‘Foul and loathsome’ or jewels of the natural world? The complicated history of human-frog relations

Shutterstock

When was the last time you saw a frog? Perhaps you came across one in your garden and wondered at its little hands, glossy skin and what looked very much like a contented smile.

Maybe you regularly see them on Instagram or TikTok, where “frog accounts” have proliferated in recent years. People share adorable cartoon frogs, coo over crocheted frogs or go gaga for frogs dressed in cute hats.

In fact, our fascination with frogs isn’t new. As our research has found, the history of human-frog relations is long and complicated – and not all of it is nice.

Why we love frogs

There is a rich history of people really loving frogs.

This is interesting, because many people much prefer mammals and birds over reptiles and amphibians.

But the frog is an exception – for a lot of reasons. People tend to be attracted to baby-like faces. Many species of frog have the large eyes characteristic of young animals, humans included.

Having no teeth and no sharp claws, they also do not seem to be immediately threatening, while many of them have beautiful skin colouring and some are improbably tiny.

Frogs are truly among the jewels of the natural world, unlike toads which – with their more mundane colours and “warty skins” – do not usually inspire the same sense of enchantment.

Their beauty connects us to the wider riches of a vibrant nature hidden from most people’s sight in the dense rainforests of the tropical regions.

And they also connect us to nature in our own backyards. At certain times of the year, they spontaneously appear in our gardens and ponds. They can feel like special visitors from the natural world.

Dissecting human feelings for frogs

Yet relationships between people and frogs haven’t always been so positive. In fact, frogs occupy complicated places across cultures all over the world.

In the Western tradition, the legacy of biblical and classical sources was both negative and longstanding.

References to frogs in the Bible rendered them the instrument of divine anger as a swarming plague.

Frogs challenged early modern zoological taxonomies, moving between classification as serpent, insect or reptile.

Perhaps their resistance to easy placement by humans explains the strong emotional language about them used by Swedish naturalist (and “father of modern taxonomy”) Carl Linnaeus.

When he considered the Amphibia in his 1758 Systema Naturae, he noted:

These foul and loathsome animals are abhorrent because of their cold body, pale colour, cartilaginous skeleton, filthy skin, fierce aspect, calculating eye, offensive smell, harsh voice, squalid habitation, and terrible venom.

In modern science, they sit in a branch of zoology, herpetology, that brings frogs together as “creeping animals” with snakes and lizards.

Frogs have also (or perhaps consequently) suffered in the service of science since at least the eighteenth century because it seemed to be possible to easily replicate experiments across multiple frog specimens.

Frogs were particularly crucial to the study of muscles and nerves. This led to ever more violent encounters between experimenters and frog bodies. Italian scientist Luigi Galvani, for example, did experiments in the late 18th century on legs of frogs to investigate what he thought of as “animal electricity”.

In this sense, frogs were valued as significant scientific objects, their value lying in their flesh, their nervous systems, rather than in their status as living, feeling beings in the world.

In time, experiments with frogs moved beyond the laboratory into the classroom. In the 1930s, schoolchildren were expected to find frogs and bring them to school for dissection in biology classes.

This practice was, however, somewhat controversial, with opponents expressing sentimental attachment to frogs and concerns that such animal cruelty would lead to barbarism.

Recognising the fragility of frogs

So, our relationship with frogs is complicated. From the frogs of Aesop’s Fables to the meme Pepe the Frog, we have projected our own feelings and frustrations onto frogs, and exploited them for science and education.

Frogs have also borne the brunt of our failures as environmental stewards.

By 1990, the world was seeing a global pattern of decline in frog populations due to destruction and degradation of habitat for agriculture and logging, as well as a global amphibian pandemic caused by the chytrid fungus.

Climate change is also making life hard for many species. In 2022, over 40% of amphibian species (of which frogs and toads are by far the largest group) were threatened with extinction. Their vulnerability has seen the frog – especially the red-eyed tree frog – become a symbol for the environment more generally.

So we should delight in frogs and marvel at how beautiful and special they are while we still can, and consider how we might help save them.

Something to reflect on next time you are lucky enough to spot a frog.The Conversation

Labour scaling back its £28 billion green pledge will impact UK housing – and public health

Shutterstock

The UK Labour party has announced its intention to reduce its £28 billion green investment pledge to less than £15 billion if elected this year. The political fallout has been been largely focused on the party’s fiscal credibility and leader of the opposition Keir Starmer’s seeming proclivity for U-turns.

A crucial question so far overlooked is what impact the cut would have on public health. The initial pledge included a key home-insulation plan to upgrade 72% – 19m homes – of the UK’s housing stock.

The revised plan, however, replaces that ambitious target with the more ambiguous statement that “millions of homes” will be refurbished. Research has long shown that uninsulated homes have consequences for health, especially for those living in poverty and in poor quality housing. This in turn places an extra burden on an already over-stretched health service.

Existing government failure

The wider societal cost of poor-quality housing in the UK is estimated at £18.6 billion a year. Such costs, however, are often ignored when housing policy is being developed and implemented.

Labour promises to deliver 1.5 million homes by “blitzing” the planning system, but it has so far ignored the potential consequences for public health.

Of course, the failure to factor in health is by no means unique to Labour policy. It is already embedded in the government’s approach. A recent academic review of government housing and transport policy found that health is notably absent, despite well-established evidence that urban spaces are making us ill. This shows that on the occasions where health is included, it is lower in a hierarchy of priorities compared to other agendas such as growing the economy.

For many years, government housing policy has been shaped by the numeric gap between supply and demand, rather than the type or quality of the housing stock. The mechanisms for delivering have been based on land release and planning reform. Successive housing policies have mentioned involving communities and supporting their health, social, and cultural wellbeing. But there have been no clear targets for ensuring house retrofit and house building positively impact public health.

In his 2010 independent review on how to reduce health inequalities in England, epidemiologist Michael Marmot showed that prioritising health in urban policies, like housing and transport, can have significant health benefits for local populations.

Our research project has shown that health should be made a central factor in all national policy and guidance that shapes urban spaces. The World Health Organization recommends explicitly including health in housing policy – and tracking its impact with recognised metrics. UK politicians have largely failed to respond.

Promising developments

In addition to positive developments in government, such as the Build Back Beautiful Commission, the opposition also has some promising ambitions. Labour is pledging to deliver a “prevention-first revolution”, in which it envisions a pro-active role for government in ensuring that everybody has the building blocks for a healthy life.

In its mission document for health policy, Labour says that retrofitting of millions of homes will “keep families warm rather than living in damp, mouldy conditions that give their children asthma”. The fact that the party is making explicit this link between housing and health signal is a potentially very positive step forward.

However, in all the furore about Labour scrapping its £28 billion pledge, this crucial link to public health has been entirely forgotten. Indeed, while Labour’s environmental policy has been carefully updated to revise and remove various targets, the preventative health agenda retains the now defunct promise to “oversee retrofitting of 19 million homes”. This is perhaps indicative of the extent to which policymakers just don’t think about health when they think about housing.

While the Conservative pledges for the next parliament remain unclear, analysis of their existing policies in government has found a failure to think about or measure the way housing and urban development policis impact health. Instead, it is merely assumed that housing policies will have positive health outcomes. Rather than making such assumptions, policymakers should be putting public health considerations at the centre of all their decision making.

To ensure that the impact any given policy has on public health is measured and acted upon, health needs to be an explicit urban planning policy outcome. It needs to be clearly defined, measurable, and built into policy implementation and political discourse.

It is also important that different government ministries and relevant stakeholders focused on public health, planning and the environment work together more effectively. Unhealthy homes should be a priority for both the housing minister and the health minister.

Healthier people are more economically productive. They have a smaller financial footprint on the NHS. In the long term, better preventative health is a key part of solving some of the UK’s biggest economic challenges, from labour shortages and sluggish productivity growth to stretched public finances.

Too often government policy is not often designed with the long-term in mind. Instead, short-term economic outcomes and political gains are prioritised – to the detriment of public health.

The best way for the government to protect public health is for every department to consider how their work impacts on it. If political and economic calculations about creating, scrapping and rescaling major projects continue to ignore health, however, politicians are likely to continue coming up with the wrong answers.The Conversation

UK peatlands are being destroyed to grow mushrooms, lettuce and houseplants – here’s how to stop it

Peat is a natural carbon sink but is often found in house plants and other retail products, particularly within the food and farming industry.

During the long, solitary days of lockdown, I found solace in raising houseplants. Suddenly stuck at home, I had more time to perfect the watering routine of a fussy Swiss cheese plant, and lovingly train our devil’s ivy to delicately frame the bookcases.

But I started noticing that these plants, sourced online, often arrived in the post with a passport. Most had travelled from all over Europe, with one common tagline: contains peat.

As a peatland scientist, these labels instantly filled me with horror. Hidden Peat, a new campaign launched by The Wildlife Trusts, is now highlighting the presence of peat in all sorts of consumer products, including house plants.

Peatlands, such as bogs and fens, store more carbon than all of the world’s forests combined. They trap this carbon in the ground for centuries, preventing it from being released into the atmosphere as greenhouse gases that would further warm the climate.

Peatlands have multiple environmental benefits. They are havens for wildlife, providing habitat for wetland birds, insects and reptiles. They supply more than 70% of our drinking water and help protect our homes from flooding.

So why on earth is peat being ripped from these vital ecosystems and stuffed inside plant pots?

From sink to source

Despite their importance, peatlands have been systematically drained, farmed, dug up and sold over the last century. In the UK, only 1% of lowland peat remains in its natural state.

Instead of acting as a carbon sink, it has become one of the largest sources of greenhouse gas emissions in the UK’s land use sector. When waterlogged peat soils are drained, microbes decompose the plant material within it and that results in the release of greenhouse gases such as methane into the air.

Most of the peat excavated, bagged up and sold in the UK is used as a growing medium for plants. Gardeners have become increasingly aware of this problem. Peat-free alternatives have been gaining popularity and major retailers have been phasing out peat-based bagged compost in recent years.

Indeed, the UK government announced they would ban sales of all peat-based compost by 2024. But this legislation has not yet been written and it seems unlikely it will be enacted before the end of the current parliament.

Even if brought in to law, this ban would only stop the sales of peat-based bagged compost of the type you might pick up in the garden centre. Legislation for commercial growers is not expected until 2030 at the earliest. So the continued decimation of the UK’s peatlands could remain hidden in supply chains long after we stop spreading peat on our gardens.

Hide and seek peat

For consumers, it’s almost impossible to identify products that contain peat or use peat in their production. All large-scale commercial mushroom farming involves peat and it is used for growing most leafy salads. It gives that characteristic peaty aroma to whisky, and, as I found out, is a popular growing medium for potted plants.

But you’d struggle to find a peat-free lettuce in the supermarket. The Hidden Peat campaign asks consumers to call for clear labelling that would enable shoppers to more easily identify peat-containing products. Shoppers are also encouraged to demand transparency from retailers on their commitment to removing peat from their supply chains.

You can ask your local supermarket about how they plan to phase out peat from their produce. Some supermarkets are actively investing in new technologies for peat-free mushroom farming.

Make informed purchases by checking the labels on garden centre potted plants or source plants from peat-free nurseries. The Royal Horticultural Society lists more than 70 UK nurseries dedicated to peat-free growing.

You can write to your MP to support a ban on peat extraction and, crucially, the sale of peat and peat-containing products in the UK. That ensures that peat wouldn’t just get imported from other European countries.

Pilots and progress

The UK government recently announced £3.1m funding for pilot projects to rewet and preserve lowland peat, with peat restoration seen as a cornerstone of net zero ambitions. This campaign calls for further acceleration of peatland restoration across the UK.

As a research of the science behind peatland restoration, I see firsthand the enormous effort involved in this: the installation of dams to block old agricultural drainage ditches, the delicate management of water levels and painstaking monitoring of the peat wetness.

I spend a lot of time taking samples, monitoring the progress, feeding results back to the land managers. Like many other conservationists, I work hard to find ways to preserve these critical habitats.

But sometimes, there may be a digger in the adjacent field doing more damage in a day than we could undo in a lifetime. That’s the reality, and the insanity, of the UK’s current peatland policies.

We heavily invest in restoring peatlands, yet fail to ban its extraction – the one action that would have the most dramatic impact. By demanding that peat is not only eradicated from garden compost, but weeded out of our supply chains, we can keep peat in the ground, not in pots.

Is the Loss and Damage Fund all that it promises to be?

Examining some of the Fund’s shortcomings and putting things into perspective after COP 28

Failed crop

 COP 28, the latest United Nations Climate Conference, came to an end in December 2023. It began with an agreement to launch the loss and damage fund, which was kick-started by the UAE’s $100 million pledge. A further 15 countries followed suit, making pledges of varying amounts, and by 2 December 2023, a cumulative total of $655.9 million had been pledged to the loss and damage fund.[1] The fund has been heralded by many as the biggest success of the entire conference and a historic agreement – being the first time that a substantive decision was adopted on the first day of the Conference. The delegates of nations present from around the world, rose in a standing ovation when the agreement was passed.  

However, although the loss and damage fund is an important and long overdue step towards getting vulnerable countries and communities funding they require, it may be too soon to be rejoicing, with many of the details regarding the fund’s set-up being highly controversial.  

A brief background to the loss and damage fund  

The loss and damage fund was first agreed to at COP 27 last year, after more than three decades of pressure from developing countries disproportionately affected by the irreversible and adverse consequences of climate change calling for funding to help them pay for the losses and damages suffered as a result of the escalating climate crisis. These impacts range from, and are caused by, increasingly frequent and more extreme weather events, as well as slow-onset events, including sea-level rise, increasing temperatures, ocean acidification, glacial retreats, loss of biodiversity, land and forest degradation, salinisation and desertification. These endanger human security and health, destroy homes, disrupt agriculture and threaten water and food security in ways that are often unequally distributed. 

As one of the outcomes of COP 27, a Transitional Committee was established and, in the lead up to COP 28, they met several times to negotiate the operationalisation and the details of the new funding arrangements. In less than a year, the Transitional Committee were able to report back with its recommendations and its text was subsequently passed at COP 28, with no objection by the parties. After almost no momentum for thirty years, the progress made in less than a year is a remarkable feat.  

Examining some of the shortcomings  

While funding for climate disaster loss and damages is vital and certainly hard fought for, one should be hesitant before deeming it a substantive win for developing countries.  

 Inadequate and duplicate pledges 

Although $655.9 million may at first glance appear like a significant amount of money, it is in fact relatively insubstantial when one considers that it is estimated that more than $400 billion is suffered in losses by developing countries each year,[2] a figure which is expected to grow as the impacts of climate change grow worse. The current funding will therefore cover less than 0.2% of developing countries’ annual needs. It has therefore been recommended that $400 billion be used as a baseline and revised upwards over time to meet increasing needs.[3] Furthermore, how to actually implement the pledges that have been made poses its own issue. This is a problem that previous funds, such as the Green Climate Fund, have faced and it is an issue that will need to be tackled to ensure that the pledges made do not simply turn out to be more broken promises.  Moreover, approximately $115.3 million of the total amount pledged to date will go towards setting up the fund rather than directly to beneficiaries of the fund.[4] Future pledges to the fund may make this operational expense insignificant, but it is still uncertain how much money will go into the fund and where it will come from. In addition, campaigners pointed out that some countries, such as the United Kingdom, were simply re-pledging money that they had already committed to, rather than offering new or additional funding.[5] In this way, the United Kingdom are simply re-branding existing forms of climate finance or development aid so as to appear to be contributing.  

Moreover, the amount pledged by some countries has been criticised for being inadequate. In particular, the United States, the world’s largest historical emitter[6] and the largest producer and consumer of oil and gas in 2023,[7] pledged only $17.5 million, an amount that still needs to be approved by Congress and accordingly hinges on the political climate and the upcoming elections. When viewed against the billions of dollars of undelivered climate finance that the United States owes to developed countries as part of its share of the annual $100 billion climate finance goal committed to by developed countries in 2009, this amount of $17.5 million certainly appears limited.[8] Of the $43.51 billion the United States owes, as part of its fair share of the $100 billion goal, only $9.27 billion has been provided to date, being a measly 21% of its targets.[9] 

It is also very telling as to what the United States’ priorities are when the $17.5 million pledged by the United States to the loss and damage fund is compared to the estimated annual $20.5 billion in fossil fuel subsidies distributed by the United States government each year,[10] contributing to the cumulative amount of $7 trillion in fossil fuel subsidies in 2022.[11] 

Historical responsibility and voluntary contributions  

During the negotiations that the Transitional Committee had leading up to COP 28, the United States, Australia and Canada all insisted that the loss and damage fund be de-linked from liability or compensation. This is in keeping with previous stance adopted by developed countries, particularly with that of the United States, who insisted that this wording be included in the decision on the adoption of the Paris Agreement which noted that loss and damage was “not a basis for liability or compensation”.[12] As the historically greatest emitters, developed countries have long opposed the establishment of the loss and damage fund over concerns that it would open the door to legal liability and compensation. Due to this refusal to assume historical accountability, communities who are experiencing the worst impacts of climate change have been forced to shoulder the consequent costs of loss and damage suffered, even though many of them, such as the Pacific Small Island Developing States, have contributed very little to climate change. This goes to the issue of equity and responsibility for the climate crisis, a sensitive topic which makes developed countries defensive. Instead of framing loss and damage in terms of responsibility and liability, wording was included in the agreed text stating that the fund is based on cooperation and facilitation.  

The approved text also stops short of demanding any payments, with the United States having fought to ensure that the contributions should remain voluntary, and the text indicated that developed countries ought to “take the lead” on providing seed money. The text “urged” developed countries to contribute to the fund, while other developing countries are “encouraged” to provide support “on a voluntary basis”.[13] The United States, Australia and Canada further insisted that contributor countries include presently high-polluting nations such as China, India, Russia and Saudia Arabia, and that only the least developed countries be eligible to benefit from the fund. As a result, high polluter states are not obligated to make any payments into the fund and instead of framing the contributions in terms of countries’ responsibility for the majority of greenhouse gas emissions, they are framed as donations made out of generosity and charity. 

The World Bank as the interim host of the Loss and Damage Fund, the set-up of the Fund’s governing board and the structure of funding 

Who would host and administer the new fund was a politically contentious sticking point in the discussions leading up to COP 28. Less than a month before COP 28, at a final and impromptu meeting called by the Transitional Committee, this matter was hastily decided. Developing countries wanted the loss and damage fund to operate as an independent United Nations body and were resistant to it being hosted by the World Bank, which many poorer countries see as an economic policy weapon wielded by the industrialised world.  

The World Bank was established by colonial powers and is known for having historically spread pro-Western ideologies and policies.[14] Moreover, it is housed in Washington DC, is headed by a US citizen, appointed by the government of the United States, as its major shareholder,[15] and has a history of operating as an Untied States policy tool. In addition, concerns were raised that the World Bank would be charging high hosting fees, has a weak climate change record and that having it host and administer the loss and damage fund would compromise the fund’s independence and give developed countries the influence over who receives the funds and who doesn’t. Developing countries eventually caved under the United States’ insistence that the fund be hosted and administered by the World Bank, and it was agreed that the World Bank would act as an interim host, provided that the World Bank would agree to certain conditions. This arrangement is to be reassessed in four years, which will result in either the fund being made fully independent or continuing as a permanent hosting situation under the World Bank.  

The United States has argued that there are practical reasons for placing the loss and damage fund under the auspices of the World Bank, and that the fiduciary experience the institution has, places it in the best position to deliver money to state beneficiaries. However, given the World Bank’s donor-recipient and loan-driven business model, reservations have been expressed as to whether developed donor countries would have a disproportionate influence, even though the Transitional Committee has recommended that the fund’s governing board have a majority of developing-country members. Although this sounds positive, the board’s composition is limited to national representatives, meaning that civil society representatives such as members of Indigenous groups, are automatically excluded. 

Another concern regarding the World Bank, is high overhead costs, with the administrative fees of the World Bank rising and likely to absorb a large portion of the funding meant for the fund’s beneficiaries. Further, developing countries have consistently called for funding to be in the form of grants, rather than debt and loan financing, which would only deepen the debt crisis and increase developing countries’ burden, which is the traditional model of financing employed by the World Bank. The agreed text stipulates that “the Fund will provide financing in the form of grants and highly concessional loans”.[16]

The ultimate success or failure of the loss and damage fund still hangs in the balance  

In order to retain any faith in the international climate policy process, there needs to be follow-through on both the pledges and commitments made. To date, climate finance has not had the best track record. Other funds, including the Green Climate Fund and the Adaptation Fund, have been radically under-resourced from the get-go and climate finance has grown at an annual rate of only 7%, which is less than half of the cumulative annual growth of 21% which is required until 2030.[17] In order for the Loss and Damage Fund to be effective, the scale of the funding will need to be increased, as what has been pledged to date constitutes a mere 0.2% of what is actually needed. 

There are also still a lot of questions to address, which the new Board of the Loss and Damage Fund will start to work through at its first meeting on 31 January 2024. Popular Gentle, the development management expert to the prime minister of Nepal, pointed out that while the establishment of the loss and damage fund is a promising start, that applause should be reserved for the time being, saying “our concern is we are excited about the establishment of the loss and damage fund. We are still cautious that the same story will be repeated. We need easy, equitable, accessible loss and damage funds without any procedural difficulties”.[18]  

So far, there are already some concerning issues that have arisen out of what has been decided. The issues that still need to be determined will prove critical to whether the fund’s operation is a success or a failure. These issues include the fact that there are no specifics yet on the scale and scope of funding, the financial targets or how the loss and damage fund will be funded going forward – although the text provides that contributions will come from a “variety of sources”.[19] The current language included in the agreed text merely invites developed nations to “take the lead”[20] in providing finance and encourages other developing country parties to make commitments. There is also little clarity regarding the performance indicators and who will be eligible to receive funding or precisely what type of climate loss and damages will qualify. Another issue will be how the application procedure will work and how quickly countries who need it will be able to access the funds and whether they will encounter any procedural difficulties in doing so. Until these things are decided, it is simply too early to greet the loss and damage fund with anything other than a mixture of cautious optimism and healthy scepticism.

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.

Loss and Damage: fears, vulnerabilities, emotions and compensation in the face of climate change

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 Loss and Damage event.

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.

post it notes about compensation with regards to loss and damage

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.

Bats are avoiding solar farms and scientists aren’t sure why

The common pipistrelle. Rudmer Zwerver/Shutterstock

As our planet continues to warm, the need for renewable energy is becoming increasingly urgent. Almost half of the UK’s electricity now comes from renewable sources. And solar accounts for one-fifth of the energy capacity installed since 2019.

Solar farms are now a striking feature of the British landscape. But despite their growth, we’re still largely in the dark about how solar farms impact biodiversity.

This was the focus of a recent study that I co-authored alongside colleagues from the University of Bristol. We found that bat activity is reduced at solar farms compared to neighbouring sites without solar panels.

This discovery is concerning. Bats are top predators of nighttime insects and are sensitive to changes in their habitats, so they are important indicators of ecosystem health. Bats also provide valuable services such as suppressing populations of insect pests.

Nonetheless, our results should not hinder the transition to renewable energy. Instead, they should help to craft strategies that not only encourage bat activity but also support the necessary expansion of clean energy sources.

Reduced activity

We measured bat activity by recording their ultrasonic echolocation calls on bat detectors. Many bat species have distinctive echolocation calls, so we could identify call sequences for each species in many cases. Some species show similar calls, so we lumped them together in species groups.

We placed bat detectors in a solar farm field and a similar neighbouring field without solar panels (called the control site). The fields were matched in size, land use and boundary features (such as having similar hedges) as far as possible. The only major difference was whether they contained solar panels.

We monitored 19 pairs of these sites, each for a week, observing bat activity within the fields’ centre and along their boundaries. Field boundaries are used by bats for navigation and feeding.

Six of the eight bat species or groups studied were less active in the fields with solar panels compared to the fields without them. Common pipistrelles, which made up almost half of all bat activity, showed a decrease of 40% at the edges of solar panel fields and 86% in their centre. Other bat species or groups like soprano pipistrelles, noctules, serotines, myotis bats and long-eared bats also saw their activity drop.

Total bat activity was almost halved at the boundaries of solar panel fields compared to that of control sites. And at the centre of solar panel fields, bat activity dropped by two-thirds.

Why are bats avoiding solar farms?

Conflict between clean energy production and biodiversity isn’t just limited to solar farms; it’s an issue at wind farms too. Large numbers of bats are killed by colliding with the blades of wind turbines. In 2012, for example, one academic estimated that around 888,000 bats may have been killed at wind energy facilities in the United States.

The way solar farms affect bats is probably more indirect than this. Solar panels could, in theory, inadvertently reduce the abundance of insects by lowering the availability of the plants they feed on. We’re currently investigating whether there’s a difference in insect numbers at the solar farm sites compared to the control sites.

Solar panels may also reflect a bats’ echolocation calls, making insect detection more difficult. Reduced feeding success around the panels may result in fewer bats using the surrounding hedgerows for commuting, potentially explaining our findings.

However, bats are also known to collide with smooth vertical flat surfaces because they reflect echolocation calls away from bats and hence appear as empty space. Research has also found that bats sometimes attempt to drink from horizontal smooth surfaces because they interpret the perpendicular echoes as coming from still water. But, given the sloped orientation of solar panels, these potential direct effects may not be of primary concern.

Improving habitats

An important lesson from the development of wind energy is that win-win solutions exist. Ultrasonic acoustic deterrents can keep bats away from wind turbines, while slightly reducing the wind speed that turbines become operational at (known as “cut-in speeds”) has reduced bat fatality rates with minimal losses to energy production. Research suggests that increasing turbine cut-in speeds by 1.5 metres per second can reduce bat fatalities by at least 50%, with an annual loss to power output below 1%.

A slightly different approach could be applied to solar farms. Improving habitats by planting native trees along the boundaries of solar farm fields could potentially increase the availability of insects for bats to feed on.

Research that I have co-authored in recent years supports this theory. We found that the presence of landscape features such as tall hedgerows and even isolated trees on farmland has a positive effect on bat activity.

Carefully selecting solar sites is also important. Prior to construction, conducting environmental impact assessments could indicate the value of proposed sites to bat populations.

More radically, rethinking the siting of these sites so that most are placed on buildings or in areas that are rarely visited by bats, could limit their impact on bat populations.

Solar power is the fastest-growing source of renewable energy worldwide. Its capacity is projected to overtake natural gas by 2026 and coal by 2027. Ensuring that its ecological footprint remains minimal is now particularly important.

Britain’s next election could be a climate change culture war

Signs indicating Ultra Low Emission Zone (ULEZ) on a street in London, UK.

A byelection in a London suburb has placed environmental policy at the centre of political debate in the UK, and could make it a key battleground in the next general election.

The Conservative party narrowly held former prime minister Boris Johnson’s seat in Uxbridge and South Ruislip, vacated after his resignation from parliament. The win has been cast as a victory driven by popular anger against climate policy, particularly London’s ultra-low emissions zone (Ulez) – an area where drivers of the highest-polluting vehicles must pay a fee.

The winning candidate positioned himself as the anti-Ulez choice, tapping into local anger at the policy. But as comments from media and politicians show, the Uxbridge story signals a new stage of national politics that demonises environmental policies. And my research suggests this could develop into an important new front in the culture war, with the power to help determine the next election.

The Ulez, created by Boris Johnson as mayor of London in 2015, is a restricted area covering central London, where vehicles must meet emissions standards or pay £12.50 to enter. Most petrol cars registered after 2005 and diesel cars registered after 2015 meet the standards. It’s primarily a public health policy, with the goal to reduce air pollution and encourage the use of low-emission vehicles.

It is due to expand into London’s outer boroughs in August 2023 – an area 18 times larger than the original zone. Legal battles and public protests have blamed London’s Labour mayor, Sadiq Khan, for the expansion of the policy.

The opposition to Ulez is highly partisan. Nationally, 59% of Conservatives oppose Ulez schemes compared to 23% of Labour voters. In London, 72% of those who voted Leave in the 2016 Brexit referendum opposed the Ulez expansion. Former Remain voters are evenly split, with 44% in support and 44% against the policy.

The Conservative prime minister, Rishi Sunak, has now distanced the government from green policies that could contribute to household expenses. Labour leader Keir Starmer acknowledged the role that Ulez played in the loss, saying that “policy matters” in elections. He also called on Khan to “reflect” on the Ulez expansion.

Climate change culture wars

My research shows net-zero policies are the next target of right-wing populism and culture wars in the UK. Narratives are emerging that tie complaints about climate policies being undemocratic or expensive to issues of Brexit, energy security and a “green elite”.

Last year, Nigel Farage called for a referendum on net-zero, policies that, in his words, had “been imposed upon people without any public discussion.”

This narrative is evident in the opposition to Ulez, despite evidence for the scheme. Air pollution has dropped dramatically one year into the Ulez expansion across inner London, and most cars in London’s outer boroughs fulfil the Ulez standards and would be unaffected by the expansion.

Yet videos of anti-Ulez protests show placards reading “Stop the toxic air lie”, a cardboard coffin with “democracy” written across it and protesters complaining about a lack of fairness and transparency in the policy.

Climate and public health measures are now linked in broader ideological battles about political and economic priorities. These policies have become fertile ground for anybody seeking to rally new supporters. Those supporters will come from groups whose day-to-day lives are impacted by these policies.

Green policies

The Ulez is not the first environmental policy to face public opposition. In 2009, the UK saw a popular campaign against the replacement of incandescent lightbulbs with LEDs.

More recently, bollards that designate low-traffic neighbourhoods have been set on fire. Opposition to these schemes has also been co-opted by conspiracy theorists arguing that climate policies are an attempt to take away personal freedoms.

We have seen the consequences of such debates before. A decade before Sunak, Conservative prime minister David Cameron stepped back from environmental policies, calling for ministers to “ditch the green crap”. This arguably led to a “lost decade” in climate policy, as well as the slowing of policies that would have reduced vulnerability in the recent energy crisis.

There is reason to hope that the coming election will be different. Public concern about the climate remains high: 67% of British people surveyed worried about climate breakdown.

And people are more likely to think that the government should do more, not less, in climate policy. New polling shows that climate concern is likely to pay off for Labour.

As I’ve argued, green policies can transform neighbourhoods. But governments must also recognise how such policies affect people’s everyday struggles, like cost of living, which are likely to dominate the next electoral cycle.

Policies must minimise impacts that disproportionately impact some groups over others. People living in London’s outer suburbs, without wide access to public transport, are more likely to own a car – driving local opposition to the Ulez in places like Uxbridge.

Ways to address this include paying people to scrap older vehicles. This is something Khan has put in place for Londoners, but has not had the government support to expand it to people living around London who would be affected when they drive into the capital.

Khan has spoken about opposition to the Ulez expansion as an “orchestrated campaign” that has moved beyond many Londoners’ “genuine concerns”. But concerns about Ulez aren’t limited to those engaging in conspiracy theories. They include residents worried about the getting to work, the school run, or caring for elderly relatives. These are problems that should be ironed out by comprehensive and sensitive policies that maximise the benefits of any change.

The coming election

The fact that a candidate can win on an anti-Ulez platform shows the effectiveness of simplifying climate action and its outcomes into what people can lose, and failing to emphasise the benefits.

The current debates miss a key point of climate action: it is never just about emissions. Opposition to the Ulez is not exclusively resistance to climate policy. It is dissent over who it impacts, and how.

The Labour party must decide whether to retreat from or double down on climate action. If the latter, the next general election will be fought as a climate change culture war.

On one side will be a group seeking to portray climate action as a costly, undemocratic and unfair exercise. On the other must be a call for climate policy that is about cleaner air, warmer homes and healthier neighbourhoods, without disproportionately impacting certain groups of people.
