Reflections on COP28’s Global Stocktake and emissions reductions

COP28 national flags at night in Dubai.

With carbon emission of around 25tCO2 per capita (global average around 4.5tCO2eq per capita) and energy demand of around 150MWh per capita (global average around 20MWh per capita), both among the 5 highest in the world, the UAE is on a per capita basis one of the largest contributor to climate change. And the host of COP28, the 28th Conference of the Parties, the main decision-making body of the UNFCCC. This makes uncomfortable reading, especially given the lack of progress in tackling human-made climate change. Then again, it probably does not matter where COPs are held as it is the agreements which countries commit to, and their success in fulfilling these commitments, which ultimately count. The number of fossil fuel business representatives makes equally uncomfortable reading. But maybe the number of fossil fuel lobbyists is a sign that they are taking COPs more seriously and rightly recognize strong action on climate change as a challenge to business as usual. Their desire to have their voices heard is testament to their recognition of the importance the UNFCCC’s process and progress on climate policy more generally.

The event itself, meanwhile, was discombobulating. Dubai’s geography of nowhere which robs you of any sense of scale and place is replicated in its Expo2020 site where COP was held. Huge distances between everything and the closed doors behind which languished side events and pavilions, mainly of countries but also of non-governmental organisations, multinational development banks, even universities, were the polar opposite of a bazaar where exchange was facilitated at previous COPs and in the space of 100 meters you might come across the International Labour Organisation, the World Bank, Egypt, Japan, Zambia, and Portugal. Thus, COP28 was sapped of interaction where browsing is enabled, chance facilitated, and happenstance happened. Instead, it felt strangely disjointed, more like an in-person zoom conference in the desert.

But the food was good, if expensive, the streets eerily safe and clean, the organization well executed, the venue shiny and spotless, public transport clean and efficient, water plentiful, and the sun reliable. It is hard to imagine impoverished countries not choosing a similar development trajectory if they were provided the opportunity. According to some calculations, African countries are sat on $10trn worth of hydrocarbons capable of pursuing such a development trajectory while pushing global warming to 6-7 degrees above pre-industrial levels. But which alternative development trajectory are we supporting which keeps these hydrocarbons in the ground while improving living standards and increasing opportunities? Access to climate finance is essential, while debt relief is the elephant in the room (I wonder how this analogy will read if we tacitly enable their extinction through poverty?). Calculations suggest that sentencing debt costs the 58 countries that make up the Vulnerable Twenty (V20) over £100bn/a. This sum would go a long way towards greening development and keeping hydrocarbons in the ground.

Instead, the Global Stocktake, the COP28 agreement, ‘calls on parties’ to ‘tripling renewable energy capacity globally and doubling the global average annual rate of energy efficiency improvements by 2030’. This is important as we need something to replace fossil fuels the Stocktake agrees to ‘transition away from’ and coal especially which it agrees to ‘phase-down’. While it will be virtually impossible to eliminate fossil fuels entirely from our economies, this language emphasizes the need to reduce their stranglehold on our energy systems. With emphasis placed on renewables and energy efficiency, this provides a plausible, just, and equitable transition pathway. While the statement that ‘abatement and removal technologies such as carbon capture and storage’ should be accelerated leaves a loophole for abated fossil fuel technologies, it emphasizes its use ‘in hard-to-abate’ sectors such as steel and cement. This loophole is to bring on board countries with very high fossil fuel dependence, not just for power generation but as the foundation of their entire economic prosperity.

Regarding transport, the document emphasizes the ‘reduction of emission from road transport on a range of pathways, including through development of infrastructure and rapid deployment of zero and low-emission vehicles’. This reference to infrastructure is highly relevant as it refers to mass transit systems which, according to the Intergovernmental Panel on Climate Change, are far more efficient than electric vehicles for example. Finally, ‘phasing out inefficient fossil fuel subsidies that do not address energy poverty or just transitions, as soon as possible’ should act as a financial driver of this transition. According to the International Monetary Fund, such subsidies amount to $7tn per year, or 7.1% of GDP. This implies that governments around the world effectively subsidise every tonne of CO2 emitted to the amount of $125. If we used this money to subsidise renewable energy and energy efficiency, as well as abatement in hard-to-treat sectors and eventually removals to account for historical emissions, 1.5 degrees is still alive, and African countries for example could be placed on a clean development trajectory towards prosperity and opportunity.

Despite tentative progress, however, parties failed to agree on the modalities of Article 6. Article 6 is the last building block of the Paris Agreement which has yet to be agreed on, with a rulebook in place that all parties agree on. Apparently, a bloc led by the US favours a light-touch approach akin to voluntary carbon markets. Unsurprisingly given their discreditation in recent months, a bloc involving the EU an African and Latin American states favours stronger checks and balances to avoid the creation of junk credits and discreditation of all market mechanism. A lot is at stake. Under the Clean Development Mechanism (CDM), the predecessor of Article 6, over £200bn was channelled into Chinese wind energy. For all its flaws, the CDM in this particular case supported the development of a renewable energy industry in a country which barely had a wind turbine installed when it came into force. Market mechanisms are powerful instruments which are difficult to guide but their potential to incentivize climate finance is evident.

To deliver the objectives of the Global Stocktake and the Paris Agreement, we need mechanisms to avoid free-riding which occurs when countries benefit from ambitious net zero emission mitigation activities in other countries without contributing to the cost. If market mechanisms are operationalised through climate clubs, this issue of free-riding can be overcome. This enables  ambition to be raised and collective action to be supported. Yet significant efforts are required to ensure that poor countries can benefit while excludable benefits are sufficient to ensure integrity and support higher ambition in climate change mitigation. The stakes are high and the Global Stocktake is a small but significant step in this direction. But a lot more climate diplomacy is necessary, alongside a collaborative spirit, to ensure that the transition away from fossil fuel is actions and that this transition is just.

How do you manage a dam when there’s a tropical cyclone in Mozambique?

Mozambique dam

I’d never given a huge amount of thought of what a dam manager did until I visited Pequenos Libombos dam in Mozambique in October 2023. Standing at the dam, in hot conditions, listening to the lived experience of people who work on the ground and explain what they do during a tropical cyclone leaves you with more understanding than any peer reviewed journal article. Context is everything. It’s why visiting the countries I’m researching is something I do given the chance.

That’s what members of Bristol projects REPRESA (co-led by Prof Elizabeth Kendon at University of Bristol & UK Met Office, Dr Luis Artur from Eduardo Mondlane University and Prof Francois Engelbrecht from University of the Witwatersrand) and SALIENT (led by Dr Rachel James, University of Bristol) did in October. The REPRESA project aims to understand compound tropical cyclone risks, impacts of tropical cyclones and improve early warning systems in Mozambique, Malawi and Madagascar. Seeing the research alignment in projects, the SALIENT team also joined. The SALIENT project aims to improve the characterisation and communication of future climate information for national adaptation planning in southern Africa.

On the field trip day, we travelled to Pequenos Libombos dam and heard from a government official from the Vila De Boane Municipality. It was this day where I had my epiphany that if I ever left academia, dam management is not my calling. Providing water to the local population is the dams primary role and it provides 2 million people within Maputo Province with access to water. That is more than 4 times the population of Bristol.

The management of Pequenos Libombos dam is difficult as there are many other people and industries to consider and keep safe and happy when making decisions. From the businesses who want to use the dam’s water for industrial purposes to the farming communities that are reliant on the water for irrigation, and hydroelectricity companies that want to use the dam to create energy to the communities downstream that may be flooded if the dam releases water too quickly. The dam catchment is also shared with 2 of Mozambique’s neighbouring countries; eSwatini and South Africa, adding another element of complexity to the dams management.

Management must carefully balance both periods of water surplus and deficit and Maputo has experienced numerous extreme weather events in recent years.  The 2015-2016 southern African drought impacted Central and Southern Mozambique and more recently the remnants of tropical cyclones in 2019, 2011, 2022 and 2023. During February 2023, Tropical Cyclone (TC) Freddy passed over Madagascar and southern Mozambique before returning a couple of weeks later to central Mozambique. It is thought to be the longest lived and have the highest accumulated cyclone energy of any cyclone on record, awaiting formal investigation from the World Meteorological Organization. Although TC Freddy didn’t directly pass over Pequenos Limbombos, its associated rainfall resulted in 250 mm of rainfall at the dam in one day. For context, the Bristol experiences 265mm rainfall, on average, in October, November and December combined. To avoid a breach of the dam, discharge was released at the maximum rate, which is more than 500 time more than normal.

Globally there is evidence that TCs and their impacts are being impacted by climate change. The frequency, intensity and storm tracks of TCs may be changing meanwhile, rising sea levels may lead to higher storm surges. Yet we know a limited amount about how tropical cyclones may act in a future with increased global sea surface and air temperatures.  TCs in the Indian Ocean are particularly under researched, but recent and frequent events have highlighted the importance of understanding TCs in a changing climate.

After hearing about the vast amount of rain that fell in February 2023, we walk past the disused hydroelectric generator that was forced to cease operation during the drought as it was no longer economically viable. It really hammered home the complexities faced when trying to manage such a huge piece of infrastructure during extreme events. Similarly, it is clear why research projects like REPRESA and SALIENT are needed to understand how tropical cyclones may behave in the future and explore how early warning systems and climate change adaptation can be strengthened.

Mozambique dam

The human side of extreme weather

After the talk at Pequenos Libombos Dam, we visited the Municipality of Vila de Boane. Vila de Boane is located roughly 15 km downstream from the dam and the River Umbuluzi passes through the municipality. The municipality experienced large scale flooding after the dam was forced to increase to maximum discharge during the February 2023 rainfall.

Despite already hearing about TC’s Freddy’s impacts at the dam, they were not as focused on the human impact. The leader of the municipality compellingly described how 16,000 people were impacted overnight, 6000 people were displaced and 6 people sadly died. The community water pump was destroyed, leaving people without water for 3 months. The municipality leader said he had never seen that amount of water passing through the municipality at such high speed before. Meanwhile, money that had been budgeted for development initiatives, had to be redirected to repair and response. It was not clear if extra money had been sourced for the development initiatives.

It was also highlighted that the increased release of water from the dam occurred over night with little warning. The municipality had been told to expect “above normal” rainfall and to avoid being close to rivers and move farming machinery further inland. But as the municipality leader questioned, what does “above normal” actually mean? People will perceive this message differently, which will influence how they act upon it. As part of the SALIENT research project, I am researching how we best communicate future climate information to decision makers and this anecdote will stay with me. It’s clear that improved communications are needed in both weather and climate services, something REPRESA is also aiming to research further.

Reflections and collaboration

After hearing about the vast amount of impacts the flooding had on Villa de Boane, we waited for our transport back to Maputo under the shade as it was too hot to stand in the sun. It was clear everyone from the REPRESA and SALIENT teams, both physical scientists and social scientists, had taken a lot from the field day. There was discussion about what the research should consider as well as the different angles that could be taken. It also fostered collaboration, SALIENT team member, Alan-Kennedy Asser, is providing the REPRESA team with analysis of precipitation trends from a multiple ensembles of climate models to characterise the range in future projections over the region. Meanwhile I spoke with some REPRESA team members in more depth about future climate information and will be providing risk communication training session in the future.

My personal key take away is that understanding the context and hearing the lived experiences of people working and living with extreme weather events enriches me as a researcher. Similarly, collaborating with researchers and practitioners on different projects enhances your work by providing questions and inputs from different standpoints. And finally, I’m too indecisive a person to ever be a good dam manager.

Climate summits are too big and key voices are being crowded out – here’s a better solution

Conference room at COP28
Conference room at COP28

Every year, the official UN climate summits are getting bigger. In 2021 at COP26 in Glasgow there were around 40,000 participants, COP27 in 2022 in Sharm el-Sheikh had 50,000.

But this year blew all previous records out of the water. More than 97,000 participants had badges to attend COP28 in Dubai in person. This raises questions about who is attending COPs and what they are doing there, who gets their voices heard and, on a more practical note, how this affects the negotiations.

For those not familiar with the COP setup, there are two “worlds” that exist side by side. One is the negotiations, which are run under the UN’s climate change body the UNFCCC, and the other is a very long list of talks and social events. These take place in pavilion exhibition spaces and are open to anyone attending, in contrast to the negotiations which are often closed to the media and sometimes closed to observers.

There is a stark difference between these worlds, with pavilion spaces featuring elaborate and inviting settings, particularly if they are well funded, while negotiations often happen in windowless rooms.

A growing sense exists among those invested in the “traditional” side of the COPs that many delegates have no intention of observing the climate talks themselves, and instead spend their time networking in the pavilions.

In terms of who attends, at COP28 there were around 25,000 “party” (country) delegates, 27,000 “party overflow” delegates (usually guests, sponsors, or advisors), 900 UNFCCC secretariat members (who run the COPs), 600 “UN overflow”, and 1,350 from “specialised agencies” such as the World Health Organization or World Bank and their overflows. That makes up just under 55,000 or half of the attendees.

The rest are intergovernmental organisations (2,000), UN Global Climate Action award winners (600), host country guests (5,000), temporary passes (500 – many issued to big private companies), NGOs (14,000 – including one of us, as part of a university delegation), and media (4,000). This is according to the UNFCCC, which places the number of attendees closer to 80,000.

The “party overflow” badges are particularly concerning. The number of delegates connected to the oil and gas industries has quadrupled from last year to around 2,400, many of whom were invited as part of country delegations. As another example, meat industry representatives became part of Brazil’s delegation, while dairy associations organised official COP side events. In the official programme, the Energy and Industry, Just Transition, and Indigenous Peoples Day featured more events by industrial giant Siemens than by indigenous people.

Practically speaking, huge numbers cause problems – this year for example there were delayed meetings, long queues, and several negotiation rooms were beyond capacity with observers and even party delegates asked to limit their numbers and leave.

Even with access to an observer badge, there is little one can contribute to negotiations. The negotiating positions are decided long before the COPs begin, and observers are rarely permitted to speak in negotiations. In addition, a lot of the negotiations are either conducted behind closed doors (called “informal-informals” with no access for the UN or observers) or even in the corridors, where negotiators meet informally to cement positions. The negotiations you can (silently) observe are usually a series of prepared statements, rather than a discussion.

So if COPs are too big and bloated, what is the alternative?

Smaller and more online

One alternative is being a virtual delegate, which one of us tried. This year’s COP trialled live streams and recordings of some of the negotiations, side events and press conferences on an official UNFCCC virtual platform for the first time. The option is a long overdue, but welcome addition. It reduces travel emissions and makes it more accessible, for instance for people with caring responsibilities and others who are unable to travel (or perhaps who refuse to fly).

Some technical teething problems are to be expected. Yet when we queried why the virtual platform didn’t livestream many of the sessions, the COP28 support team pointed us to the official COP28 app. Our employer, the University of Bristol, had advised us not to download the app because of security concerns, which again raises serious issues around transparency and accountability in UNFCCC spaces, as well as freedom of speech and assembly in COP host countries.

Not being there in person also has downsides. As a virtual observer, it’s harder to judge the atmosphere in a negotiation room, to stumble upon and observe spontaneous negotiations happening in corridors, or participate in or observe protests. While indigenous voices were rarely heard in the livestreamed negotiations and events, the Indigenous People’s Pavilion offered a chance to hear them – but only if you were in Dubai. The virtual alternative is a good option to observe negotiations, but it means missing out on some of the civil society lifeblood of COP.

Another option is to limit access to COPs – for example, limiting the in-person negotiations only to the most vital participants. Party tickets could be limited, with lobbyists from fossil fuel industries tightly controlled and priority given to climate victims, indigenous communities and underrepresented countries. Side events and pavilions could take place a few months before the COPs, increasing the chances of influencing negotiations, since positions are cemented early. There is no reason these only need to happen in one place once a year, there could be regional meetups in between, allowing for formal contact more often.

These issues of access, transparency and influence have serious implications on negotiation outcomes and climate action. After undergoing various draft iterations that offered options ranging from “no text” to “phasing out” or “down” fossil fuels, this year’s final agreement does not include a commitment to phasing out. This watered-down agreement reflects the inability of indigenous peoples and the most climate vulnerable countries to meaningfully participate in the negotiations – future COPs must trim down to make their voices heard.

The clam before the storm

Cornish mussels

How can you not love a bivalve? I certainly spent seaside holidays picking long, thin razor shells out of the sand on the beach, marvelling at their sharp edges and brown and cream patterned growth lines. I still love clambering over rocky shorelines thick with the blue-black ovals of mussels, encrusted with limpets and rough barnacles, layered with salty strands of seaweed.

Bivalves are a keystone part of a rich ocean fauna, interlocked with the ecology of the marine environment and intertwined with lives of both ancestral and modern humans. Seafood, and particularly shellfish such as mussels, oysters, cockles, scallops and clams have long been part of the human diet. The European market for mussels alone topped 600,000 kg last year (FAO.org), the majority of which are consumed in France, Spain and Italy. Just take a moment to imagine the delicious fragrance of a seafood paella, and you will appreciate why they are so popular. Unfortunately, the future of shellfish is becoming more uncertain as the climate heats up. The days when oysters are used to fire the passions of young lovers, or indeed for lovers to gift each other nacre jewellery or pearls, may be coming to an end. Climate change is likely to lead to a scarcity of oysters and an inability for them to thrive, meaning much smaller individuals, which will make such tokens harder to obtain, more expensive or simply not available anymore.

Aside from being a food source, bivalves are an essential part of the ecosystem in both marine and freshwater habitats. One important task that bivalves do is to filter the water, collecting particles of microalgae, phytoplankton, bacteria and silt. The indigestible particles are packaged with mucus and excreted as a sandy deposit that sinks to the sea floor. In this way, bivalves help to clean murky, turbid water. Some bivalves do this at an incredible rate; green mussels (Perna analiculus) or sea scallops (Placopecten magellanicus) can filter in excess of 10 gallons of water every day. Removing and digesting the algae reduces the number of algal blooms that occur, and sticking sediment particles together so they sink, clears the water. This allows light to penetrate deeper into the ocean, benefitting photosynthetic organisms attached to the seabed.

The structure of the seabed is altered by the presence of bivalves. Some bivalves, such as Venus clams (Veneridae) bury themselves in soft sediments, helping to stabilise the sand. Others attach themselves to rocks using strong root-like threads. Reefs are reinforced by encrusting bivalves, which help to reduce shoreline erosion. This feature is becoming more important as the frequency and intensity of severe weather events is set to increase.

The shells of bivalves are made from either calcite or aragonite, which are different forms of calcium carbonate. The two forms are found in different species and at different stages of the life cycle. They have slightly different chemical properties but they both contain carbon in the form of carbonate, which molluscs extract from seawater. When the shellfish die, the shells drift to the ocean floor to begin the transition into rock such as limestones, ultimately locking carbon away and becoming an important carbon sink. Increasing carbon dioxide in the atmosphere means more carbon dioxide is dissolving in the oceans. Although this might seem like a bonus for the shell-building fauna, the carbon dioxide forms a weak solution of carbonic acid, and this is altering the pH of seawater. Acid reacts with carbonate, dissolving it, so that shelly sea creatures have to work harder to build and maintain their shells.

The complexity of reefs and other underwater habitats is enhanced by bivalves, not just with structural strength, but with complex architecture, which provides niches, refuges and points of attachment for other species. Plenty of creatures apart from humans enjoy munching on bivalves. Squid and octopods can prise the hinged shells apart using the suckers on their tentacles to get at the tasty meat inside. Bivalves also contribute to the food web by spawning large volumes of eggs and larvae. These drift on the ocean currents, providing an essential food source for pelagic fish and other hunters, such as baleen whales.

Having convinced you that bivalves are amazing, what does the future hold for hinged molluscs? Many studies have looked at how different conditions affect bivalves, with some coming to positive, and some to negative conclusions. Cherry picking the answer you want does not necessarily reflect the overall trend and can be quite misleading. One way that scientists use to get an overview of multiple studies is to carry out a meta-analysis. This is a way of combining all the studies to give a statistical probability to each value being tested.

We gathered data on how well bivalves grow under different conditions predicted to change by climate change models. Growth rate can be altered by temperature, pH, oxygen availability and salinity. Ocean temperature is increasing, and this will affect the metabolism of cold-blooded organisms, who rely on the external environment for internal temperature regulation. The pH of the oceans is becoming more acidic, causing the thinning of shells in some shelled sea creatures.

Areas of the ocean are becoming periodically, or permanently short of oxygen. This is happening in two ways. There are widespread dead zones spreading out from the estuaries of major rivers (e.g the Ganges or Mississippi) where nitrates and other pollutants are causing eutrophication, which uses up all the dissolved oxygen. Across water courses as a whole, less oxygen is present in water at higher temperatures because oxygen doesn’t dissolve as well in warm as opposed to cold water. Recent summer heat-waves have left a raft of dead, floating, aquatic organisms, both in marine settings and in inland lakes and rivers. Last summer I caught the fire-brigade pumping air into a local fishing pond, trying, mostly unsuccessfully, to prevent the fish from suffocating.

The last climate stressor that we included in our meta-analysis was salinity. As the planet warms, leading to the melting of ice-caps and glaciers, the sea level will rise with the influx of fresh water. This will alter the salinity, especially in the areas of melt-water run-off around coasts where most species of bivalves tend to live. We wanted to see if salinity changes would be problematic for bivalves, and how that would interact with the other climatic changes. One of the interesting things about meta-analyses is that the effect not only of individual stressors can be evaluated, but also the effect of the interaction of stressors. Do they combine to become more than the sum of their parts, or do they counteract each other to have an overall negligible effect?

What we found was that each of the environmental stressors individually reduced bivalve growth, but that combinations of stressors – such as a temperature increase coupled with an increase in acidity – acted together to reduce growth in a more pronounced way. If climate changes in the way that most models are predicting, then they are also predicting fewer, smaller bivalves that take longer to mature. This may disproportionally affect low-income, island nations, such as the Maldives, where a large proportion of the diet is sourced directly from the sea. For the fishing industry, this means sustainable harvesting limits will need to be adjusted over time to allow time for bivalves to grow to maturity.

This is particularly pertinent because the types of bivalves that have been studied are nearly all either commercial or easy-to-collect reef-building species. They come predominately from the northern hemisphere, and there is a distinct lack of studies on African and tropical species. There are over 100 families of bivalves, of which just 18 have had quantitative growth studies carried out. In the studies we used, 81% of them were on just four families: oysters (Ostreidae), mussels (Mytilidae), scallops (Pectinidae) and Venus clams (Veneridae). There are an awful lot of families we know nothing about, and it isn’t necessarily true that how one species responds informs us accurately about what another species might do. Temperature, for example, really slows down the growth of oysters, scallops and mussels, but can increase the growth of Venus clams and pen shells (Pinnidae). I can see you throwing your hands in the air and asking “Why??”

In this case, the answer seems to lie in the habitat or mode of life that the bivalve inhabits. The families that grow faster in warm waters are the type that bury themselves deep in the soft sand or mud of the seabed. This seems to act as a protective buffer against temperature changes, whereas bivalves attached to the surface are exposed to temperature extremes and so they show reduced growth.

The data became even more interesting when we looked at how different life stages responded to environmental stressors. Nearly all (84%) of the studies we could include in our meta-analysis had been carried out on eggs/larvae or juveniles. This of course, makes perfect sense if you are studying growth, as young organisms do an awful lot more growing than adults. It does, however, leave a hole in the data, and that can lead to biased conclusions.

Very young bivalves, which are generally a free-living part of marine plankton, grow less well in warm, acidic or low oxygen conditions. Low salinity doesn’t seem to be an issue. Adults, on the other hand, can tolerate warm, acidic or low oxygen conditions singly, but struggle when these occur in combination. Adults are also strongly affected by low salinity (in the very few studies that have tested this). Again, this makes reasonable sense. Adults are fixed to whichever rock they settled on, and so survival depends far more on metabolic tolerance to environmental extremes. Mobile, free-swimming larval forms have a greater ability to move away from uncomfortable conditions, searching for somewhere they can flourish.

However, larval vulnerability indicates that in the future bivalve populations (as opposed to individuals) will grow more slowly and may suffer from recruitment and settlement problems. It may be difficult, slow or impossible for bivalve colonies to regenerate after disturbance or harvesting, leading to major population crashes.

Climate change is going to pose some challenges to the populations of bivalves. Bivalves supply the seafood industry, filter our water, stabilise our shorelines and produce planktonic larvae, which bolsters the ocean food web. Minimising the effects of climate change will help to protect this keystone fauna and enable them to continue to form such an essential part of the natural world. I hope my children’s children can still delight in finding ropes of mussels and living pearls.

Disinformation campaigns are undermining democracy. Here’s how we can fight back

Misinformation is debated everywhere and has justifiably sparked concerns. It can polarise the public, reduce health-protective behaviours such as mask wearing and vaccination, and erode trust in science. Much of misinformation is spread not by accident but as part of organised political campaigns, in which case we refer to it as disinformation.

But there is a more fundamental, subversive damage arising from misinformation and disinformation that is discussed less often.

It undermines democracy itself. In a recent paper published in Current Opinion in Psychology, we highlight two important aspects of democracy that disinformation works to erode.

The integrity of elections

The first of the two aspects is confidence in how power is distributed – the integrity of elections in particular.

In the United States, recent polls have shown nearly 70% of Republicans question the legitimacy of the 2020 presidential election. This is a direct result of disinformation from Donald Trump, the loser of that election.

Democracy depends on the people knowing that power will be transferred peacefully if an incumbent loses an election. The “big lie” that the 2020 US election was stolen undermines that confidence.

Depending on reliable information

The second important aspect of democracy is this – it depends on reliable information about the evidence for various policy options.

One reason we trust democracy as a system of governance is the idea that it can deliver “better” decisions and outcomes than autocracy, because the “wisdom of crowds” outperforms any one individual. But the benefits of this wisdom vanish if people are pervasively disinformed.

Disinformation about climate change is a well-documented example. The fossil fuel industry understood the environmental consequences of burning fossil fuels at least as early as the 1960s. Yet they spent decades funding organisations that denied the reality of climate change. This disinformation campaign has delayed climate mitigation by several decades – a case of public policy being thwarted by false information.

We’ve seen a similar misinformation trajectory in the COVID-19 pandemic, although it happened in just a few years rather than decades. Misinformation about COVID varied from claims that 5G towers rather than a virus caused the disease, to casting doubt on the effectiveness of lockdowns or the safety of vaccines.

The viral surge of misinformation led to the World Health Organisation introducing a new term – infodemic – to describe the abundance of low-quality information and conspiracy theories.

A common denominator of misinformation

Strikingly, some of the same political operatives involved in denying climate change have also used their rhetorical playbook to promote COVID disinformation. What do these two issues have in common?

One common denominator is suspicion of government solutions to societal problems. Whether it’s setting a price on carbon to mitigate climate change, or social distancing to slow the spread of COVID, contrarians fear the policies they consider to be an attack on personal liberties.

An ecosystem of conservative and free-market think tanks exists to deny any science that, if acted on, has the potential to infringe on “liberty” through regulations.

There is another common attribute that ties together all organised disinformation campaigns – whether about elections, climate change or vaccines. It’s the use of personal attacks to compromise people’s integrity and credibility.

Election workers in the US were falsely accused of committing fraud by those who fraudulently claimed the election had been “stolen” from Trump.

Climate scientists have been subject to harassment campaigns, ranging from hate mail to vexatious complaints and freedom-of-information requests. Public health officials such as Anthony Fauci have been prominent targets of far-right attacks.

The new frontier in attacks on scientists

It is perhaps unsurprising there is now a new frontier in the attacks on scientists and others who seek to uphold the evidence-based integrity of democracy. It involves attacks and allegations of bias against misinformation researchers.

Such attacks are largely driven by Republican politicians, in particular those who have endorsed Trump’s baseless claims about the 2020 election.

The misinformers are seeking to neutralise research focused on their own conduct by borrowing from the climate denial and anti-vaccination playbook. Their campaign has had a chilling effect on research into misinformation.

How do we move on from here?

Psychological research has contributed to legislative efforts by the European Union, such as the Digital Services Act or Code of Practice, which seek to make democracies more resilient against misinformation and disinformation.

Research has also investigated how to boost the public’s resistance to misinformation. One such method is inoculation, which rests on the idea people can be protected against being misled if they learn about the rhetorical techniques used to mislead them.

In a recent inoculation campaign involving brief educational videos shown to 38 million citizens in Eastern Europe, people’s ability to recognise misleading rhetoric about Ukrainian refugees was frequently improved.

It remains to be seen whether these initiatives and research findings will be put to use in places like the US, where one side of politics appears more threatened by research into misinformation than by the risks to democracy arising from misinformation itself.

The cracks are where the light gets in – studying vulnerabilities in Elite Incumbent Resistance at COP26

Elites are often rightly blamed for resisting bold action needed to tackle climate change. But what if elite alliances are more fragile than commonly assumed? What if we consider Elite Incumbent Resistance – to transitions in food, energy and finance – not as a homogenous bloc of resistance towards sustainability transitions, but instead as made up of temporary, fragile alliances held together in ways that might be amenable to disruption?

A group of interdisciplinary researchers brought together by the British Academy’s Virtual Sandpit on Just Transition, set out to explore this question by piloting a new approach to studying the COP26 Climate Summit.

Starting Points

This thought experiment emerged from a critique of existing International Political Economy literature on climate negotiations which tends to focus on intense resistance to transitions to sustainable societies from elite groups benefiting from the status quo. This approach tends to homogenise incumbent elite-alliances, making them appear more robust than they really are. We were curious about what would happen if we instead focused on the vulnerabilities inherent in any alliances and how they are maintained and undone in climate negotiations. 

As tools to help us think this through, we firstly turned to  Laclau and Mouffe’s work on hegemony and socialist strategy. This is an old text but still relevant as it shows how all alliances are built on what they call relations of ‘equivalence’, which means, in simple terms, coming to a compromise about what key words  (‘sustainable growth’ anyone?) mean. These equivalences, however, are always temporary and can, in theory, be unsettled. 

Secondly, we drew on performance theory to highlight the importance of physical, visual and material performances, like UNFCCC COPs, for creating and maintaining the impression of elite unity and competence in managing global public goods like the climate. 

Thirdly, Science and technology studies helped us to consider how to spot opportunities to facilitate rapid transitions by identifying how changing material circumstances bridge differences between previously opposed groups.  Equally, the multiple-level perspective, drew our attention to how changing conditions at regime, landscape and local levels might have the opportunity to both disrupt existing alliances and bring seemingly opposed groups together through shared interests.  

With these theories, we set out to explore whether we could find cracks in elite forums at COP, explore whether there were strains in these performances and if we could identify potentially new alliances that might come out of opening up these cracks. 

What happens next is described in the rest of this blog and illustrated with cartoons we developed to capture the essence of what we came to think of as the highly vulnerable performances of elite power at COP26. 

Performing the COP

What struck us about COP26 was that it was not a coherent space managed and led by a single elite. Instead, it had a multiple, fragmented nature. COP is perhaps best thought of as a bewildering circus of loosely connected activities masquerading as a single event.  

This is not surprising. A COP meeting gathers multiple groups with contradictory aims: simultaneously a forum of intergovernmental negotiations, a trade fair for corporate partners and a site of civil society participation and protests. 

What is also noticeable, however, is that this fragmentation is hierarchically organised through complex procedures of inclusion and exclusion (Blue Zones, Green Zones, Access Cards, T shirts) with different levels of access accorded to different groups depending on their symbolic importance for validating the COP performance of an inclusive and diverse forum (recognised and acceptable scientists, a selection of key green activists and representatives of youth indigenous peoples). This is stage managed in such a way as to produce a performance that reassures a public watching via television and social media that there is a coherent plan for averting climate disaster. 

Cartoon of a clown made of two children standing on top of each other, standing at the entrance to a circus talking to two other children saying "of course we're a real-life legitimate, trustworthy, responsible, ticket-taking adult".

The hierarchical format of the COP, most clearly expressed through the separation between the Green and Blue Zones, maintains the impression of there being a central heart of power,  where decisions are made and the global response is organised. Such an impression produces the performance of the COP as the key forum for climate action, to which interested parties must desire access, and in which those with access must desire ever greater access to the ever elusive and ever more exclusive circle of decision-making. Despite this, the event was characterised in fact by a pluralisation of decision-making activities – by side dinners for particular industries, by one to one meetings, bilateral agreements, and encounters between civil society, academic, policy, media and industry groups. 

From this perspective, the ultimate discursive illusion of the COP is that there is a central seat of power, of the governing and corporate elites that come together in a single place to take decisive actions to avert climate change disaster. The selective inclusion of groups like youth, indigenous peoples and green civil society organisations in particular, served to bolster this illusion – creating an impression of participation while reducing them to symbolic speeches and side-events. We call this co-option because, in reality, such groups and individuals appear to have had almost no influence on the outcomes of COP, the Glasgow Climate Pact or the agreement of the Paris Rulebook.

Intra-elite cracks and potential for new alliances

Drawing on Laclau and Mouffe, we mapped out the discursive nodal points that created the equivalences that allowed the highly fractured parties in the discussions to sustain the perception of elite consensus on addressing the climate crisis. Unsurprisingly, they were vague. All organised around the major overarching nodal point – the climate model itself. The key nodal points of the official COP26 were  ‘keeping one degree alive’ and ‘achieving net-zero’, with vague references to  ‘technological solutions’ and ‘nature-based solutions’ as means of achieving this. These were reiterated in a variety of different formulations across all aspects of the COP – from the public-facing leaders’ stages to online materials to banners and marketing materials throughout the events. A second critical overarching nodal point was the false universalism that diffused responsibility from specific actors and instead presented this as a shared global challenge – the repeated marketing phrases ‘we are all in this together’ and ‘we have to turn anger into action’. This papered over the intra-elite cracks that would emerge between the winners and losers of any genuinely decisive action. 

Cartoon of balloons with environmental slogans on being popped with a person saying "your plan was more than just hot air though, right?"

Given the intentional ambiguity of these discursive nodal points, there is unsurprisingly growing debate about what they actually mean, and signs of intra-elite cracks emerging around them. This creates opportunities for civil society groups and others wanting to build alternative strategies to combat the climate emergency. 

An example of such a crack is evident in the concept of ‘nature-based solutions’ and what it can mean to different incumbent elite factions. The fossil fuel industry is happy to endorse this phrase, provided that it allows offsets from carbon emissions through reforestation to reach ‘net-zero’. Such an interpretation of nature-based solutions would in practice mean doubling down on current practices which have led to the displacement of indigenous peoples and peasants to make room for offsetting plantations.  On the other hand, the insurance industry, which routinely underwrites extractive projects, has grown increasingly aware of its exposure to climate change. We can see an emerging rift between them and their long time fossil fuel partners as they begin to demand that nature-based solutions involve the preservation of biodiverse nature. 

At COP we saw some examples of civil society groups seeking to re-articulate and open up the contestation in terms such as ‘nature-based solutions’ and ‘we are all in this together’ as a way of disrupting intra elite relationships. For example, we saw joint activities between the insurance giant Aviva, civil society group Global Canopy and representatives of Amazonian Indigenous peoples speaking of their partnership in identifying companies contributing to deforestation and divesting from them. Such activities take these key terms and make visible the differences in how they might be interpreted in ways that can either enable the preservation of climate destroying practices or empower current custodians of biodiverse nature. Such events successfully undermine the performance of consensus in events such as COP and outline routes towards rearticulating these key terms in ways that allow new alliances to form between marginalised and elite groups. 

Reflections

Our team started out with hunches that there were cracks in elite incumbent resistance to serious actions to tackle climate change. What we came away with after using these theoretical tools to make sense of the COP was less a sense of cracks in alliances, and instead a sense of profound fragmentation, disconnection between hugely varied actors and a desperate struggle to create the impression of coherence and the successful performance of control. We were left wondering whether the search for ever greater access to inner sanctums of elite power that seemed to be ever more elusive would be a wise strategy for actors wishing to shift the debate. Instead, starting from an assumption of heterogeneity and disorganisation, of failed performances and illusory central points of power would suggest there are opportunities in thinking horizontally, organising in multiple sites, pluralising and making visible the heterogeneity of decision-making moments. At the same time, rather than simply naming the over-familiar discursive nodal points as ‘blah blah blah’ – recognising them precisely as a key means of organising alliances, the challenge may be to occupy, interpret and reinterpret these terms. If we are all in it together – let’s make it all of us, if we are looking for nature-based solutions – let’s have a conversation about the different meanings of nature and what we are looking for a solution to. 

In other words – our sense is that it no longer makes sense to only search for cracks in elite incumbent resistance. But instead – there is merit in starting from the assumption that it is a miracle that alliances are made at all, and working creatively and persuasively to make visible the divides that sit both beneath the performance of events like COP, and the disagreements that sit within the language of consensus. From that, new alliances might be made.

In July 2023, the Cabot Institute for the Environment and Universities UK Climate Network hosted an event focusing on loss and damage.

Loss and damage captures the adverse impacts and irreversible harm caused by climate-related events and changes, particularly in vulnerable and disadvantaged communities. It recognizes that some effects of climate change cannot be fully mitigated or adapted to, leading to tangible and intangible losses such as loss of lives, livelihoods, cultural heritage, and ecosystems.

Loss and damage has become a significant topic in international climate negotiations, with discussions focusing on how to address and compensate for unavoidable consequences of climate change, often in the context of financial support and liability for those responsible.

Participants at the workshop were encouraged to speak openly about their emotions around climate change losses and what it might look like to be compensated. They spoke openly and with great vulnerability about what they feared and hoped for.

Artist Andy Council was on hand to take notes and created a stunning piece of art to reflect our conversations – centering around greed, grief, injustice, and anger.

Andy said ‘When I attended the event, I heard different thoughts on the issues raised and I wanted to get as many of these into my artwork piece as possible. I wanted to get the different ideas as smaller components into a larger image, a symbol: the dollar sign. It seemed relevant as unfortunately things come down to money – profit from industry over climate change and habitat loss, money put towards preserving prestigious artefacts, less industrialised nations bearing the brunt of climate change and the funding to compensate for the loss and damage. The artwork is overall quite dark and gloomy, however there are elements of hope within the piece with images of resistance and preservation of the world’s natural landscape.’

Art has the unique ability to transcend language and cultural barriers, making it a powerful tool for raising awareness and fostering understanding of complex global issues like loss and damage. Climate change often feels abstract and distant, but through art, it can become tangible and emotionally resonant. Art can also convey the urgency and gravity of the issue, bridging gaps between different communities and fostering a sense of shared responsibility.

The UK Climate network said ‘we are keen to make sure that our research connects to people and action outside the academic world. It was great to see Dr Alix Dietzel engaging the public on this topic and bringing the conversation to life through art.’

COP27 established a Loss and Damage Fund that aims to provide financial assistance to nations most vulnerable and impacted by the effects of climate change. However, the UNFCCC has not yet specified which countries should contribute to the fund, and who will be eligible to receive help. As we head into COP28, all eyes will be on the negotiations to see whether these aspects of the fund can be nailed down.

Navigating divorce and environmental challenges: Implications in a changing world

Broken heart on wooden table.In an ever-evolving world, societal dynamics are continually shifting, reflecting the multifaceted nature of the human experience. One of the most profound changes we have witnessed in recent decades is the transformation of family structures, with divorce becoming a common facet of modern life across various societies. For instance, according to Office for National Statistics as of 2021, 42% of marriages in England and Wales end in divorce. Alongside this social evolution, we grapple with an equally pressing issue—the burgeoning environmental emergency. These two forces converge dramatically in more profound ways than we might realise. In this blog, I will explore the profound impact of dealing with divorce within the context of logistical and emotional anxiety brought about by the existential threat to our environment. 

The complex landscape of divorce

Divorce, a life-altering event, affects not just the couple but an entire ecosystem—that is to say, the nuclear family. My PhD research findings illuminated the diverse experiences of young people whose parents divorced in different cultural contexts. After interviewing forty-four young people aged between 11 and 16 in Türkiye and England, what emerged strongly was a nuanced understanding of the variegated effects – both uplifting and otherwise, of divorce particularly for children. 

For instance, more than half of the Turkish young people reported changing schools due to their parents’ divorce. While many didn’t directly attribute their school performance to the divorce, several children noted that changing schools positively impacted their performance. This aligns with global trends. A changing world demands adaptability, and some young people see education as their anchor, providing hope and a chance to take control of their lives, as reported by older participants in my study. 

Emotional turmoil is a common aspect of divorce, with sadness and confusion being initial reactions. However, as my research indicates, many young people learn to adapt and grow from their experiences over time. Young people also emphasised the pivotal role that the home environment plays in shaping children’s experiences during and after divorce. Exposure to violence or maltreatment within the family environment can have a lasting negative impact. 

Environmental challenges as an added layer

While navigating the intricate terrain of divorce, families now face an additional layer of complexity—the environmental challenges we face as a society. The world around us is changing rapidly due to issues such as climate change, pollution, and resource depletion. These challenges bring new dynamics to the fore within family life. A changing world presents economic challenges for families. Natural disasters, resource scarcity, or environmental policies have disrupted livelihoods and strained family finances, each feeding into existing marital tensions and ultimately increasing the likelihood of divorce. According to the World Economic Forum, climate change and related disasters could cost the global economy $360 billion annually by 2030. 

Environmental crises force families to relocate or to become displaced persons, creating stress and uncertainty. The number of internally displaced people around the world reached 71.1 million as of the end of 2022, an increase of 20% from the previous year, according to the Internal Displacement Monitoring Centre’s flagship annual report. Today’s displacement crises are growing in scale, complexity and scope, and factors like food insecurity, climate change, and escalating and protracted conflicts are adding new layers to this phenomenon. 

The emotional toll of witnessing environmental devastation can affect family members’ mental health. Anxiety, depression, and a sense of helplessness may surface, adding to the existing emotional challenges of divorce. The Mental Health Foundation in the UK has highlighted the impact of environmental issues and climate change on mental health, that stress and anxiety are rising. 

A call for resilience and adaptation

As we stand at the crossroads of these two significant societal shifts—divorce and environmental challenges—it becomes clear that resilience and adaptation are paramount. Families must not only weather the storms of marital dissolution but must also equip themselves to confront the environmental storms of a changing world. 

Empowering young people with education and awareness about both divorce and environmental issues is crucial. They need the tools to understand, adapt, and make positive contributions to their lives and the world around them. Families need robust support systems. This includes access to mental health services for emotional well-being and community networks that can assist during economic hardship or environmental crises. 

Having to separate houses also means having to double the expenses for two different households. While divorce can bring about significant changes and challenges, it is important to recognise that it can also have positive aspects, such as the potential for personal growth and the opportunity to create healthier family dynamics. In my research, 95% of the young people said they feel happier after their parents’ divorce than before and during. Therefore, sustainable living practices can help mitigate the impact of both divorce and environmental challenges. This not only contributes to the preservation of the planet but also instils values of responsibility and resilience in younger generations. Divorce cannot solely be seen as a breakdown of a family unit. On the contrary, families can advocate for action on environmental issues, fostering a sense of purpose and unity. Addressing these challenges collectively can lead to positive changes that benefit the family unit and the world. 

In our rapidly changing world, families often find themselves at the intersection of two transformative forces—personal and environmental upheaval. At first glance, divorce and environmental challenges may seem unrelated. However, the two have a profound connection. Studies have shown that the environment plays a significant role in shaping our mental health and well-being. The increasing prevalence of climate change-related stress and anxiety, as documented by the American Psychological Association, highlights this link.

When we realise that environmental changes impact our mental health, we can begin to see the intricate relations between these forces. By acknowledging the complexity of divorce within the context of a changing world, understanding the implications of environmental challenges on our emotional well-being, and fostering resilience and adaptation, we can empower families to not only survive but thrive in this shifting landscape. Ultimately, through these challenges, we can shape a more compassionate, resilient, and sustainable world for generations to come.

The microclimate of Mount Stewart, Northern Ireland: Planning and planting for the future

Think of Northern Ireland and think of its weather. I wouldn’t blame you if all you knew about Northern Ireland is that it is cool (arguably cold) and wet. A famous pub in Belfast has a sign outside stating “Belfast has seven types of rain: Monday, Tuesday, Wednesday…” The temperature typically doesn’t get above 25 °C. While England’s all-time record temperature is 40.3 °C, Northern Ireland’s is a relatively low 31.3 °C – quite a difference. It doesn’t seem like the sort of place you would attempt to grow banana plants outside all year around. However, in the National Trust’s Mount Stewart gardens, on the shore of Strangford Lough in County Down, that is exactly what you’ll find.

Climate and climate change occurs at all different scales. We all know that the climate we experience as a resident of, for example, Belfast varies from that of Northern Ireland, or the UK in general, or Europe, or the globe. At the same time, even within a relatively small area like Northern Ireland, there will be a large range of unique microclimates as a result of highly localised physical features.

Mount Stewart is one such example of a unique microclimate. Being close to sea level keeps frost and cold extremes at bay, while it has a dense 8-acre sea plantation – a shelter belt of established woodland on the shoreward side of the gardens – that shelters tender plants from the worst of colder sea winds and salt spray. Cocooned behind the shelter belt, Mount Stewart’s range of gardens grow a huge variety of plants, including bananas, and have been voted one of the best gardens in the world.

Gardeners working at Mount Stewart have known its microclimate is unique for years, however in the face of climate change, the National Trust are taking action to get ahead of the curve and plan for the future. In recent years, high storm surges have caused salt water intrusion in parts of the ornamental gardens, with the salinity subsequently damaging or killing many plants that required replanting. Long-term, such flooding seems inevitable and is even expected to take the sea plantation with it.

To understand exactly the nature of the microclimate of Mount Stewart and the importance of its sea plantation, University of Bristol have teamed with the National Trust to install 12 sensors around the site to measure the temperature, humidity, soil temperature, soil moisture and precipitation. These sensors cover the ornamental gardens’ microclimate (some sensors are literally amongst the banana plants), the walled gardens and in the land surrounding the microclimate, on the edge of agricultural areas and on the shoreward side of the sea plantation.

The project began monitoring in July 2023. We hoped to capture how the microclimate responded through summer heatwaves, but instead had the rainiest July on record in Northern Ireland. Not to worry – that’s interesting data to capture too. The project plans to run for as long as we can maintain the sensors at the site, capturing heatwaves, cold snaps, storms and everything in between over the coming years. The variation in climate across Mount Stewart will be quantified, including the effect of the much-hyped sea plantation. At the same time, the offset between the weather recorded by Met Office or reanalysis data products for Northern Ireland in general versus at the Mount Stewart site will be calculated, allowing local scale bias corrections to be applied to historic records and potentially future climate model projections.

The initial results collected so far provide some tantalising and surprising insights. At least for a cool, wet summer like Northern Ireland has just experienced, the microclimate is in fact not warmer than the surrounding countryside. The warmest part of the site – perhaps unsurprisingly – was found to be the walled garden. However, that still leaves me wondering how the bananas survive in ‘normal’ Northern Irish weather! The true test of the microclimate and sea plantation’s effect may be seen during the coming winter, where this area is expected to be milder and significantly less frost prone.

The information from this project will be used by the National Trust to plan their next steps. They are already in the process of planting the next generation of sea plantation further inland and ultimately the majority of the gardens may have to move. Understanding how the microclimate varies will help inform where is best to resituate the existing planting and gardens. This project is a trial and if it is useful and successful, the National Trust may carry out similar analysis at other sites across the UK. As a climate researcher, I love data! However, a research question which we hope to answer with this project is whether more data is always necessary? The gardening team at Mount Stewart have a very detailed knowledge of the microclimate in terms of what plants thrive where and when – just not in terms of graphs and numbers. We will explore whether quantifying this microclimate provides added value above and beyond tacit local knowledge.

Gardeners always keep one eye on the future. Seeds are sown expecting shoots in the spring. Saplings are planted expecting an orchard in decades to come. This project will help the National Trust’s gardening team to make decisions that will shape this garden into the next century and maybe beyond. This ‘seedcorn funding’ has taken on a different and very literal meaning.

This work was funded by University of Bristol’s Third Sector Impact Seedcorn funding. The project team includes Alan Kennedy-Asser and Simon Cobb (School of Geographical Sciences) and Keith Jones (National Trust). Thanks to the gardening team at Mount Stewart including Mike Buffin, Robert Wilson and Abigail Wilson for their support in running and maintaining the sensors. You can hear Mike Buffin discussing the project on BBC Radio Ulster’s Gardeners’ Corner programme here.
