Detectable impacts of Climate Change in the UK; a new review for the next Climate Change Risk Assessment

Posted on January 17, 2023March 29, 2023 by janet.crompton

2022 was another year of “unprecedented” weather. Provisional figures indicate that it was the warmest so far recorded, with almost every month hotter than average. Much of the country had a notably mild New Year, despite the cold snap in mid-December. This was preceded by the third warmest autumn on record, and that by a scorching summer, with the hottest day ever recorded in July. But summer’s heat waves were also accompanied by a rise in the number of daily deaths across the country. People around the world are becoming increasingly more aware of events like these, and their impact in the UK is particularly concerning amidst the ongoing cost-of-living, energy, and NHS crises.

Ahead of the Fourth UK Climate Change Risk Assessment (CCRA4), the Climate Change Committee (CCC) are asking what we know about the impact of past and present climate change on natural and human systems here in the UK specifically. At the global level, the 2021 IPCC sixth assessment working group I (AR6 WGI) report concluded: “It is unequivocal that human influence has warmed the atmosphere, ocean and land.” This single sentence has been informed by decades of research by people at the cutting edge of climate science, and the evidence to support it has grown stronger in every IPCC report since they began. The report goes on to say: “Human-induced climate change is already affecting many weather and climate extremes in every region across the globe.” In last year’s follow-up AR6 WGII report on impacts, adaptation, and vulnerability, an extensive assessment of the science led to the conclusion that the magnitude and proliferation of extremes caused by human-induced climate change were having widespread, adverse impacts on both nature and people. Last summer’s heatwaves, and the concurrent dangers to health, homes, and the environment, were a graphic illustration of the nature of such human-induced impacts.

The study of impacts that informed this conclusion is the remit of climate scientists who specialise in “detection and attribution”. This is about looking at what is changing around us and being able to pinpoint the cause(s) – and particularly, whether human-induced climate change is at the root. To inform CCRA4, the CCC have commissioned a joint Bristol and Exeter University team to conduct a comprehensive review of the detection and attribution of climate change in the UK. The first part will cover the detection and attribution of weather and climate changes in the UK, relevant to specific “Climate Impact Drivers”. The second will cover attribution of impacts on societal, infrastructural, economic, and biodiversity sectors. We aim to find out what studies have been done so far, where the gaps are, and whether they can be filled, or if they would require substantial new methodological or data advances. We aim to identify variables which are key drivers of multiple impacts, and, importantly, where further attribution analysis is needed – especially when the impacts are critical for UK risk.

Detection and attribution is a rapidly evolving field, with focus only relatively recently moving from meteorological attribution (e.g., weather extremes) to impact attribution (e.g., consequences for humans and ecosystems). Our systematic review of the literature and final report will be key to tying it all together, especially with the UK focus required by the CCC. But to be able to present the most up-to-date findings, and thus make informed recommendations, we need to ensure that we have considered all relevant studies. So, if you, or someone you know, has published on this topic – whether UK specific or not – we’d like to know about it! Help shape and inform the next UK Climate Change Risk Assessment.

Four ways winter heatwaves affect humans and nature

Posted on January 11, 2023April 14, 2023 by janet.crompton

An extreme winter heatwave meant countries across Europe experienced a record-breaking New Year’s Day. New daily temperature records for the month of January were set in at least eight countries: Belarus, Czechia, Denmark, Latvia, Liechtenstein, Lithuania, Netherlands and Poland.

In many cases the temperatures were not just breaking the old highs, but smashing them by massive margins. On a typical January day in Warsaw, Poland, temperatures would barely go above freezing, yet the city recently experienced 19℃, breaking the previous January high by 5.1℃.

New January records were set at thousands of individual stations in many other countries such as 25.1℃ at Bilbao airport in Spain, 0.7℃ hotter than the previous record set only last year. Large areas of central and Eastern Europe experienced temperatures 10℃ to 15℃ warmer than average for this time of year – and that has persisted through the week.

When Europe experienced extreme heat in July of last year, more than 20,000 died. Fortunately winter heatwaves are much less deadly, but they can still affect both human society and natural ecosystems in many ways.

1. Less energy is needed

In Europe deaths due to cold weather vastly outweigh those caused by extreme high temperatures – in the UK there are ten times more. Warmer winters will reduce this excess mortality and, with the current cost-of-living crisis, many will have been relieved that a heatwave meant less energy was needed to heat their homes.

Electricity demand is influenced by things like the time of day, the day of the week and socio-economic factors like the COVID pandemic or the war in Ukraine. The weather also makes a difference. For example, in Poland and the Netherlands demand was noticeably lower than average, especially since January 1 was a Sunday. The extent of the heatwave also meant countries could refill some of their winter gas reserves, or large batteries.

2. Reduced yields for some crops

Winter warm spells don’t always have such a positive impact though. For instance a lack of snow in the mountains affects agriculture and can reduce crop yield, since snow creates an insulating blanket that prevents frost from penetrating into the soil. This means snow can actually increase soil moisture more than rainfall, thus improving growing conditions later in the season.

The big snow melt in spring time replenishes reservoirs and allows hydroelectricity generation, but unexpected snow melt can lead to flooding. Changes to the timings of these events will require preparation and adaptation to enable a steady supply of water to where we need it.

Warmer temperatures will create longer growing seasons in many regions. This is not always the case though. A recent study showed that for alpine grasslands an earlier growing season (the point when snow has melted entirely) leads to ageing and browning of the grasses in the later part of the summer.

3. The snow economy is in trouble

The heatwave caused ski resorts across the Alps to close in what should be their busiest time of year. In January the slopes would be expected to have a good covering of snow – but instead we saw green grassy fields.

This hits the local economy where many people rely on winter sports tourism. Events such as the Adelboden alpine ski World Cup are relying on artificial snow, which comes with a further environmental cost increasing the carbon footprint of ski resorts and requiring a large water supply. Indeed, the Beijing winter Olympics used the equivalent of daily drinking water for 900 million people to generate the artificial snow it required.

4. Animals out of sync with the climate

We humans are perhaps fortunate, as we are able to adapt. Some ski resorts have already opened mountain bike trails in winter to offer alternative tourism, but wildlife and ecosystems cannot adjust so rapidly.

In the mountains many species, such as ptarmigan and mountain hares, change their colouring for winter to camouflage in the white snow. The timing of this change is determined by length of day – not the temperature or amount of snow. These creatures are at greater risk of being preyed on when it is warmer.

Over the past century heat extremes in Europe have increased in intensity and frequency. Both the general warming and heatwave events have been firmly attributed to humans.

Future projections suggest these trends will continue and heatwaves in both summer and winter will get hotter, last longer, and occur more often. We need to learn to adapt for these changes in all seasons and think about the impacts on everyone – and everything – on our planet.

After COP27, is 1.5C still alive?

Posted on December 2, 2022April 16, 2023 by janet.crompton

Try booking a train on Boxing Day in the UK and you’ll soon find out that none are running. Well, not entirely. One small railway line managed by indomitable Gauls still holds out: The Eurostar. And airports are still being served as plains are still flying. Obvs. If this is not just the present, but also our future, then Mia Mottley, Prime Minister of Barbados, is right: “We’re at 1.2 degrees now. If in 5 years we’re at 1.5, then we’re…. we’re…. I won’t use that word now.”

Apologies, I got carried away. Back to planes (flying), trains (not running) and automobiles (driving). These are symptomatic of the mess we’re in, but nothing compared to the mess we’re heading towards. And nothing compared to the mess others already find themselves in. If these current trends continues the number of refugees is set to increase from 21m in 2022 to 1bn in 2050 (Mia Mottley again). Many originate from Africa which is responsible for only 4% of global emissions (and 2% of historic emissions) and home to 600m without access to electricity.

While inanimate capital moves freely across borders, refugees are increasingly prevented from doing so. As their poverty and desperation grows in a warming world, their cost of borrowing increases as the World Bank uses per capita income as a proxy for borrowing conditions. Consequently, such countries (Least Developed Countries – LDCs) borrow at 12-14% while rich countries (the G7) borrow at 1-4%. According to Indian economist Joyashree Roy, these countries need 7% growth per year to escape their plight but if they are borrowing at +10% cost of capital, this growth will not be powered by renewables.

Neither will the focusing on the supply of renewables alone deliver Sustainable Development Goals (SDGs). Demand-side interventions are necessary to shift investment patterns and create new economic opportunities that are synergistic with SDGs. But all this depends on infrastructure access and empowerment to make the right choices, which in turn are determined by the flow of finance. To put on track for 1.5C, these flows need to quadruple to $4-6trn per year, according to Macky Sall, Senegalese President and current Chairperson of the African Union. IPCC Chair Hoesung Lee, goes one step further: access to capital is the key determinant of limiting global warming to 1.5C. Concessional access to finance was provided during COVID, as Mia Mottley pointed out, so why can it not be provided to prevent climate catastrophe?

On the plus side, outgoing COP26 President Alok Sharma suggests that 90% of global emissions are covered by a net zero target. Almost 1/3rd of the global population who accumulate 55% of global GDP are covered by Emissions Trading Schemes, according to Stefano de Clara, Head of the International Carbon Action Partnership. Then again, the current average carbon price stands at $6/t. This needs to increase to $75/t by 2030 to limit warming to 2C, not to mention 1.5C, according to Dora Benedek from the International Monetary Fund.

Without such a massive increase in the cost of carbon, emissions are expected to be only 12% (6GtCO2eq) lower in 2030 compared to today. What about magic??, you might interject at this point. Current Carbon Capture and Storage (CCS) and Direct Air Capture (DAC) capacities amount to around 4 hours of global emissions and are projected to amount to around 16 hours in 2030, according to Sven Teske from the University of Technology Sydney. To keep 1.5C alive, we need to reduce emissions by 30-50% in by 2030 (Dora Benedek again). So yes to magic, but only within the bounds of Kate Raworth’s famous doughnut.

And it’s both sides of that tasty doughnut that we need to bear in mind. On the outside, quick wins are possible regarding methane emissions which are responsible for around 0.5C of the 1.2C we stand above pre-industrial levels. Around 0.1C of warming can be addressed by cutting gas flaring and coal related methane emissions at no cost, according to US Deputy Climate Envoy Richard Duke. Addressing such emissions deliver invaluable co-benefits on the inside. 15% of all deaths (7million a year) are due to polluted air, according to Jane Burston of the Clean Air Fund. Companies are having to pay a pollution premium to attract talent to polluted cities.

It’s both the out and the in-side of the doughnut we need to focus on for a just transition to happen. According to Heike Henn, of Germany’s Federal Ministry for Economic Affairs and Climate Action and whatnot, Article 6 is emerging as the mechanism to allocate those $100bn/a finance pledged in Paris which never materialised as well as the trillions needed to implement NDCs (Nationally Determined Contributions) and SDGs.

Not Article 6.2 though, which requires adjustments in GHG registries upon the transfer of a carbon credits (Internationally Transferrable Mitigation Outcome – ITMO) and is already seeing emerging economies lowering ambition in their NDCs. Article 6.4 is what I’m talking about. Although it will take years to be operationalised, its infrastructure is being developed as we speak. The Climate Action Data Trust, for example, can significantly lower transaction costs of carbon market transactions through automated Measurement, Reporting and Verification (MRV) and tokenisation to create digital carbon assets.

Now it’s down to ambitious countries to form alliances and agree on a sharing mechanism to convert the 1.5C target into demand for mitigation action distributed dynamically over time, and measure achievement and contribution using Article 6.4. “Getting to net zero is a heroic task”, according to Dirk Forrister of the International Emissions Trading Association, “and you won’t get there by going alone”.

Where does this leave 1.5C? “I find it hard to stay optimistic”, said Nichola Sturgeon on day 1 of COP27. I echo this sentiment. Yet we need to remind ourselves that the combined net zero targets, if implemented, can limit warming to 1.7C and increase, yes INCREASE, global GDP by 0.4% per year, according to Fatih Birol from the IEA. If we can’t sort this out, bins will be burning.

COP27: What really happened on finance, justice and Loss and Damage?

Posted on December 2, 2022April 16, 2023 by janet.crompton

The Cabot Institute for the Environment sent three delegates to the recent Conference of the Parties 27 (COP27). Drs Alix Dietzel (Sociology, Politics and International Studies); Colin Nolden (Bristol Law School); and Rachel James (Geographical Sciences) were present for most of the first week and Colin was there for the full two weeks. As the Institute has observer status with the United Nations Framework Convention on Climate Change, Alix, Rachel and Colin had the chance to engage with policy makers and climate policy experts from around the world to help promote climate action which is informed by the best evidence and research.

We asked them to give an update on their experience at COP27 and as a result, whether the pledges made at COP27 would mean that 1.5C is still achievable.

Drs Colin Nolden and Alix Dietzel at COP27.

Climate finance – Dr Colin Nolden

Colin’s research interests span sustainable energy policy, regulation and business models and interactions with secondary markets such as carbon markets and other sectors such as mobility. COP27 was an opportunity for him to talk directly to policymakers about implementing the Paris Agreement and to people directly affected by climate policy decisions.

Here are Colin’s post-COP thoughts:

“Alongside Loss and Damage, the main issue discussed at COP is climate finance for decarbonisation. The $100bn/yr pledged in Paris has never materialised and to add injury to insult, rich countries can borrow at 4%, whereas poor countries borrow at 14%, as Mia Motley, Prime Minister of Barbados, pointed out in her speech on Day 1. Under these conditions, investments in fossil fuel infrastructures pay off, but investments in renewables do not. An endless number of panel discussions and side events on ‘climate finance’ and ‘accelerating the clean energy/net zero transition’ are testament to this gap.

“Article 6 of the Paris Agreement is a mechanism to overcome this funding gap by providing the legal foundation to finance decarbonisation projects in a country in exchange for carbon credits provided by another. Whether these should lead to according adjustments in emissions inventories, as is the case under bilateral agreements using Article 6.2, is controversial. How Article 6.4 will deal with this issue is still unclear and is unlikely to be agreed on at successive COPs. Negotiations on Article 6 will determine the climate credit and finance architecture for years to come.”

Climate justice – Dr Alix Dietzel

Alix is Associate Director for Impact and Innovation at the Cabot Institute for the Environment and an environmental justice scholar. Her role at COP27 was to observe the negotiations and critically reflect on whose voices were heard and whose were left out of the discussion, as well as concentrating on whether topics such as Loss and Damage and just transition were being given adequate space and time during the negotiations.

Dr Alix Dietzel at COP27.

Here are Alix’s reflections from COP27:

“Despite much excitement over a new Loss and Damage fund, there is backsliding on commitments to lower emissions and phasing out fossil fuels. As an academic expert in just transition who went along this year hoping to make a difference, I share the anger felt around the world about this outcome.

“Attendance at COPs is strictly regulated. Parties (negotiating teams), the media, and observers (NGOs, IGOs, and UN Agencies) must all be pre-approved. Observers have access to the main plenaries and ceremonies, the pavilion exhibition spaces, and side-events. The negotiation rooms, however, are largely off limits. Most of the day is spent listening to speeches, networking, and asking questions at side-events. The main role of observers, then, is to apply indirect pressure on negotiators, report on what is happening, and network. Meaningful impact on and participation in negotiations seemed out of reach for many of the passionate people I met.

“It has long been known that who gets a say in climate change governance is skewed. As someone working on fair decision making as part of just transition, it is clear that only the most powerful voices are reflected in treaties such as the Paris Agreement. Despite being advertised as ‘Africa’s COP’, COP27 has further hampered inclusion. The run up was dogged by accusations of inflated hotel prices and concerns over surveillance, no chance to organize protests, and warnings about Egypt’s brutal police state.

“Arriving in Sharm El Sheik, there was an air of intimidation starting at the airport, where military personnel scrutinized passports. Police roadblocks featured heavily on our way to the hotel, and military officials surrounded the COP venue the next morning. Inside the venue, there were rumours we were being watched and observers were urged not to download the official app. More minor issues included voices literally not being heard due to unreliable microphones and the constant drone of airplanes overhead. Food queues were huge, and it was difficult to access water to refill our bottles. Sponsored by Coca Cola, we could buy soft drinks. Outside of COP, unless I was accompanied by a man, I faced near constant sexual harassment, hampering my ability to come and go freely.

“Who was there and who was most represented at COP27 also concerned me. The United Arab Emirates (UAE) registered the largest party delegation with more than 1,000 people, almost twice the size of the next biggest delegation, Brazil. Oil and gas lobby representatives were registered in the national delegations of 29 different countries and were larger than any single national delegation (outside of the UAE). At least 636 of those attending were lobbyists for the fossil-fuel industry. Despite the promise that COP27 would foreground African interests, the fossil lobby outnumbers any delegation from Africa. These numbers give a sense of who has power and say at these negotiations, and who does not.

“All this to say, I am not surprised at the outcomes. There is some good news in the form of a new fund for Loss and Damage – but there is no agreement yet on how much money should be paid in, by whom, and on what basis. More worryingly, the outcome document makes no mention of phasing out fossil fuels, and scant reference to the 1.5C target. Laurence Tubiana, one of the architects of the Paris Agreement, blamed the host country, Egypt, for the final decision.

“COP27 produced a text that clearly protects oil and gas petro-states and the fossil fuel industry. The final outcomes demonstrate that despite the thousands who were there to advocate for climate justice, it was the fossil fuel lobby who had most influence. As a climate justice scholar, I am deeply worried about the processes at COPs, especially given next year’s destination: The United Arab Emirates. Time is running out and watered-down commitments on emissions are at this stage deeply unjust and frankly dangerous.”

Loss and Damage – Dr Rachel James

Rachel is a climate scientist, focusing on African climate systems and developing climate science to inform and advance climate change policy. Her previous research has been designed to progress international climate policy discussions, including the COP process, and she has analysed the impacts of global mitigation goals, comparing different warming scenarios (1.5°C, 2°C and beyond). At COP27, she engaged in adaptation discussions, to learn more about how science can support national adaptation planning, to guide her new research programme “Salient”, a UKRI Future Leaders Fellowship to improve climate information for adaptation, primarily in southern Africa.

Dr Rachel James (fourth from right) at COP27.

In her previous work, Dr James has also looked at how science can support policy discussions about ‘Loss and Damage’, from climate change, and at COP27 she followed discussions on Loss and Damage, as well as taking part in a workshop to establish a network of African researchers focusing on Loss and Damage. Rachel reflects on her experience of COP and the Loss and Damage discussions:

“The COP is now a huge event, with hundreds of discussions happening simultaneously, and many thousands of people, (almost) all pushing for climate action, and acting on it in their own ways. There are lots of things going on, deals being struck, collaborations forming, alongside the official UNFCCC business.

“This was supposed to be the “COP of implementation”, as the Paris Agreement and the rulebook are already in place. Some said we were largely beyond negotiation.

“However, the Global South came ready to negotiate, particularly on Loss and Damage. They wanted a finance facility on Loss and Damage to be established. Negotiations began in the weekend before the COP, and – after negotiating all night with no food – the developing countries succeeded in getting this onto the formal agenda.

“Over the two weeks of the COP, my perception was that there was a huge shift on Loss and Damage. Once it was on the official agenda, it was much easier to talk about. It has been a very contentious issue. Broadly, the most vulnerable countries have called for mechanisms to address the fact that they are, and will continue to, experience loss and damage from climate change impacts like sea level rise and extreme weather. Those countries who have emitted the most fear this could lead to unlimited liability. When I first started working on it I’d often get a worried look when I mentioned the topic.

“In a side event during the first week at Sharm El Sheikh, I heard someone say “some magic has happened” and we can now talk about this in the mainstream. We also saw a series of announcements from countries committing finance for Loss and Damage. Then, finally, after two weeks of negotiations ran into extra time, countries agreed to establish a fund for Loss and Damage.

“This was a huge victory for the developing countries. Lots of questions remain about how it will work, who will pay into it, and who will benefit, but nevertheless it marks a big step. Developing countries (especially AOSIS, the Alliance of Small Island States) have been working on this for decades. The negotiators work so hard, often into the night, it’s incredible.

“My overall view is that COP continues to be a difficult process, but it is shifting, maybe substantially. Many view COP as a talk shop and suggest it’s a waste of time, but I disagree. Although the process is tortuous, slow, and frustrating, it is the best one we have, and still vital. Progress is way too slow but there is progress. Every country is represented, and we don’t have any other process on climate change where that is the case. The developing countries have power in numbers at the COP that I am not sure they have in any other forum on climate change.”

Dr Alix Dietzel (fourth from right on the back row) at COP27

Is 1.5C still alive?

Colin: “The International Energy Agency expects fossil fuel demand to peak as early as 2025. However, with all countries harbouring exploitable fossil fuel resources racing to extract them (with our former Secretary of State for Business, Energy and Industrial Strategy Rees-Mogg vowing in September 2022 to “squeeze every last drop of oil” out of the North Sea) and key initiatives such as the Glasgow Financial Alliance for Net Zero failing to deliver on their promises, fossil fuels will not be phased out anytime soon.

“At the same time, pinning our hopes on Carbon Capture and Storage (CCS) is misguided as current capacities amount to four hours of global emissions and International Energy Agency projections suggest that capacities in 2030 will amount to 16 hours of emissions. This implies that in the absence of a sustained global financial commitment towards demand reduction or sustainable supply, limiting average global temperature rise to 1.5 above will be very difficult indeed.”

Rachel: “A key goal in Glasgow and in Sharm El Sheikh has been to keep 1.5°C alive. Some countries were attempting to backslide on mitigation goals during the final days, but in the end 1.5°C remained in the text. It’s disappointing that we didn’t see an increase in ambition from Glasgow, but 1.5°C is still there – even if “on life support”, as noted by Alok Sharma.

“It’s easy for us to do an academic analysis and speculate as to whether or not we think 1.5°C is politically feasible. But the IPCC has spelled it out clearly: every fraction of a degree of warming matters. What’s important is that we increase ambition to reduce emissions, and we phase out fossil fuels, so that we can limit global warming as much as possible.”

Towards urban climate resilience: learning from Lusaka

Posted on November 29, 2022March 29, 2023 by janet.crompton

“This is a long shot!”

These were the words used by Richard Jones (Science Fellow, Met Office) in August 2021 when he asked if I would consider leading a NERC proposal for a rapid six-month collaborative international research and scoping project, aligned to the COP26 Adaptation and Resilience theme. The deadline was incredibly tight but the opportunity was too good to pass up – we set to work!

Background to Lusaka and FRACTAL

Zambia’s capital city, Lusaka, is one of Africa’s fastest growing cities, with around 100,000 people in the early 1960s to more than 3 million people today. 70% of residents live in informal settlements and some areas are highly prone to flooding due to the low topography and highly permeable limestone sitting on impermeable bedrock, which gets easily saturated. When coupled with poor drainage and ineffective waste management, heavy rainfall events during the wet season (November to March) can lead to severe localised flooding impacting communities and creating serious health risks, such as cholera outbreaks. Evidence from climate change studies shows that heavy rainfall events are, in general, projected to increase in intensity over the coming decades (IPCC AR6, Libanda and Ngonga 2018). Addressing flood resilience in Lusaka is therefore a priority for communities and city authorities, and it became the focus of our proposal.

Lusaka was a focal city in the Future Resilience for African CiTies and Lands (FRACTAL) project funded jointly by NERC and DFID from 2015 to 2021. Led by the Climate System Analysis Group (CSAG) at the University of Cape Town, FRACTAL helped to improve scientific knowledge about regional climate in southern Africa and advance innovative engagement processes amongst researchers, practitioners, decision-makers and communities, to enhance the resilience of southern African cities in a changing climate. I was lucky enough to contribute to FRACTAL, exploring new approaches to climate data analysis (Daron et al., 2019) and climate risk communication (Jack et al., 2020), as well as taking part in engagements in Maputo, Mozambique – another focal city. At the end of FRACTAL there was a strong desire amongst partners to sustain relationships and continue collaborative research.

I joined the University of Bristol in April 2021 with a joint position through the Met Office Academic Partnership (MOAP). Motivated by the potential to grow my network, work across disciplines, and engage with experts at Bristol in climate impacts and risk research, I was excited about the opportunities ahead. So when Richard alerted me to the NERC call, it felt like an amazing opportunity to continue the work of FRACTAL and bring colleagues at the University of Bristol into the “FRACTAL family” – an affectionate term we use for the research team, which really has become a family from many years of working together.

Advancing understanding of flood risk through participatory processes

Working closely with colleagues at Bristol, University of Zambia, University of Cape Town, Stockholm Environment Institute (SEI – Oxford), Red Cross Climate Centre, and the Met Office, we honed a concept building on an idea from Chris Jack at CSAG to take a “deep dive” into the issues of flooding in Lusaka – an issue only partly explored in FRACTAL. Having already established effective relationships amongst those involved, and with high levels of trust and buy-in from key institutions in Lusaka (e.g., Lusaka City Council, Lusaka Water Security Initiative – LuWSI), it was far easier to work together and co-design the project; indeed the project conceived wouldn’t have been possible if starting from scratch. Our aim was to advance understanding of flood risk and solutions from different perspectives, and co-explore climate resilient development pathways that address the complex issue of flood risk in Lusaka, particularly in George and Kanyama compounds (informal settlements). The proposal centred on the use of participatory processes that enable different communities (researchers, local residents, city decision makers) to share and interrogate different types of knowledge, from scientific model datasets to lived experiences of flooding in vulnerable communities.

The proposal was well received and the FRACTAL-PLUS project started in October 2021, shortly before COP26; PLUS conveys how the project built upon FRACTAL but also stands for “Participatory climate information distillation for urban flood resilience in LUSaka”. The central concept of climate information distillation refers to the process of extracting meaning from multiple sources of information, through careful and open consideration of the assumptions, strengths and limitations in constructing the information.

The “Learning Lab” approach

Following an initial evidence gathering and dialogue phase at the end of 2021, we conducted two collaborative “Learning Labs” held in Lusaka in January and March 2022. Due to Covid-19, the first Learning Lab was held as a hybrid event on 26-27 January 2022. It was facilitated by the University of Zambia team with 20 in-person attendees including city stakeholders, the local project team and Richard Jones who was able to travel at short notice. The remainder of the project team joined via Zoom. Using interactive exercises, games (a great way to promote trust and exchange of ideas), presentations, and discussions on key challenges, the Lab helped unite participants to work together. I was amazed at the way participants threw themselves into the activities with such enthusiasm – in my experience, this kind of thing never happens when first engaging with people from different institutions and backgrounds. Yet because trust and relationships were already established, there was no apparent barrier to the engagement and dialogue. The Lab helped to further articulate the complexities of addressing flood risks in the city, and showed that past efforts – including expensive infrastructure investments – had done little to reduce the risks faced by many residents.

One of the highlights of the Labs, and the project overall, was the involvement of cartoon artist Bethuel Mangena, who developed a number of cartoons to support the process and extract meaning (in effect, distilling) the complicated and sensitive issues being discussed. The cartoon below was used to illustrate the purpose of the Lab, as a meeting place for ideas and conversations drawing on different sources of information (e.g., climate data, city plans and policies) and experiences of people from flood-affected communities. All of the cartoons generated in the project, including the feature image for this blog, are available in a Flickr cartoon gallery – well worth a look!

Integrating scientific and experiential knowledge of flood risk

In addition to the Labs, desk-based work was completed to support the aims of the project. This included work by colleagues in Geographical Sciences at Bristol, Tom O’Shea and Jeff Neal, to generate high-resolution flood maps for Lusaka based on historic rainfall information and for future climate scenarios. In addition, Mary Zhang, now at the University of Oxford but in the School of Policy Studies at Bristol during the project, collaborated with colleagues at SEI-Oxford and the University of Zambia to design and conduct online and in-person surveys and interviews to elicit the lived experiences of flooding from residents in George and Kanyama, as well as experiences of those managing flood risks in the city authorities. This work resulted in new information and knowledge, such as the relative perceived roles of climate change and flood management approaches in the levels of risk faced, that was further interrogated in the second Learning Lab.

Thanks to a reduction in covid risk, the second lab was able to take place entirely in person. Sadly I was unable to travel to Lusaka for the Lab, but the decision to remove the virtual element and focus on in-person interactions helped further promote active engagement amongst city decision-makers, researchers and other participants, and ultimately better achieve the goals of the Lab. Indeed the project helped us learn the limits of hybrid events. Whilst I remain a big advocate for remote technology, the project showed it can be far more productive to have solely in-person events where everyone is truly present.

The second Lab took place at the end of March 2022. In addition to Lusaka participants and members of the project team, we were also joined by the Mayor of Lusaka, Ms. Chilando Chitangala. As well as demonstrating how trusted and respected our partners in Lusaka are, the attendance of the mayor showed the commitment of the city government to addressing climate risks in Lusaka. We were extremely grateful for her time engaging in the discussions and sharing her perspectives.

During the lab the team focused on interrogating all of the evidence available, including the new understanding gained through the project from surveys, interviews, climate and flood data analysis, towards collaboratively mapping climate resilient development pathways for the city. The richness and openness in the discussions allowed progress to be made, though it remains clear that addressing flood risk in informal settlements in Lusaka is an incredibly challenging endeavour.

What did we achieve?

The main outcomes from the project include:

Enabling co-exploration of knowledge and information to guide city officials (including the mayor – see quote below) in developing Lusaka’s new integrated development plan.
Demonstrating that flooding will be an ongoing issue even if current drainage plans are implemented, with projections of more intense rainfall over the 21st century pointing to the need for more holistic, long-term and potentially radical solutions.
A plan to integrate flood modelling outputs into the Lusaka Water Security Initiative (LuWSI) digital flood atlas for Lusaka.
Sustaining relationships between FRACTAL partners and building new links with researchers at Bristol to enable future collaborations, including input to a new proposal in development for a multi-year follow-on to FRACTAL.
A range of outputs, including contributing to a FRACTAL “principles” paper (McClure et al., 2022) supporting future participatory projects.

It has been such a privilege to lead the FRACTAL-PLUS project. I’m extremely grateful to the FRACTAL family for trusting me to lead the project, and for the input from colleagues at Bristol – Jeff Neal, Tom O’Shea, Rachel James, Mary Zhang, and especially Lauren Brown who expertly managed the project and guided me throughout.

I really hope I can visit Lusaka in the future. The city has a special place in my heart, even if I have only been there via Zoom!

“FRACTAL-PLUS has done well to zero in on the issue of urban floods and how climate change pressures are making it worse. The people of Lusaka have continually experienced floods in various parts of the city. While the problem is widespread, the most affected people remain to be those in informal settlements such as George and Kanyama where climate change challenges interact with poor infrastructure, poor quality housing and poorly managed solid waste.” Mayor Ms. Chilando Chitangala, 29 March 2022

COP27: how the fossil fuel lobby crowded out calls for climate justice

Posted on November 22, 2022April 16, 2023 by janet.crompton

COP27 has just wrapped up. Despite much excitement over a new fund to address “loss and damage” caused by climate change, there is also anger about perceived backsliding on commitments to lower emissions and phase out fossil fuels.

As an academic expert in climate justice who went along this year, hoping to make a difference, I share this anger.

“Together for Implementation” was the message as COP27 got underway on November 6 and some 30,000 people descended on the Egyptian resort town of Sharm El Sheik. The UNFCCC strictly regulates who can attend negotiations. Parties (country negotiation teams), the media and observers (NGOs, IGOs and UN special agencies) must all be pre-approved.

I went along as an NGO observer, to represent the University of Bristol Cabot Institute for the Environment. Observers have access to the main plenaries and ceremonies, the pavilion exhibition spaces and side events. The negotiation rooms, however, are largely off limits. Most of the day is spent listening to speeches, networking and asking questions at side-events.

The main role of observers, then, is to apply indirect pressure on negotiators, report on what is happening and network. Meaningful impact on and participation in negotiations seems out of reach for many of the passionate people I met.

Who does – and doesn’t – get a say

It has long been known that who gets a say in climate change governance is skewed. As someone working on fair decision making as part of a just transition to less carbon-intensive lifestyles and a climate change-adapted society, it is clear that only the most powerful voices are reflected in treaties such as the Paris Agreement. At last year’s COP26, men spoke 74% of the time, indigenous communities faced language barriers and racism and those who could not obtain visas were excluded entirely.

Despite being advertised as “Africa’s COP”, COP27 further hampered inclusion. The run up was dogged by accusations of inflated hotel prices and concerns over surveillance, and warnings about Egypt’s brutal police state. The right to protest was limited, with campaigners complaining of intimidation and censorship.

Arriving in Sharm El Sheik, there was an air of intimidation starting at the airport, where military personnel scrutinised passports. Police roadblocks featured heavily on our way to the hotel and military officials surrounded the COP venue the next morning.

Inside the venue, there were rumours we were being watched and observers were urged not to download the official app. More minor issues included voices literally not being heard due to unreliable microphones and the constant drone of aeroplanes overhead, and a scarcity of food with queues sometimes taking an hour or more. Sponsored by Coca Cola, it was also difficult to access water to refill our bottles. We were sold soft drinks instead.

Outside of the venue, unless I was with a male colleague, I faced near constant sexual harassment, hampering my ability to come and go from the summit. All these issues, major and minor, affect who is able to contribute at COP.

Fossil fuel interests dominated

In terms of numbers, the United Arab Emirates (UAE) registered the largest party delegation with more than 1,000 people. The oil and gas-rich nation of just 9 million people had a delegation almost twice the size of the next biggest, Brazil. More troublingly, the oil and gas lobby representatives were registered in the national delegations of 29 different countries and were larger than any single national delegation (outside of the UAE). According to one NGO, at least 636 of those attending COP27 were lobbyists for the fossil-fuel industry.

Despite the promise that COP27 would foreground African interests, the fossil lobby outnumbers any delegation from Africa. These numbers give a sense of who has power and say at these negotiations, and who does not.

Protecting the petrostates

The main outcomes of COP27 are a good illustration of the power dynamics at play. There is some good news on loss and damage, which was added to the agenda at the last moment. Nearly 200 countries agreed that a fund for loss and damage, which would pay out to rescue and rebuild the physical and social infrastructure of countries ravaged by extreme weather events, should be set up within the next year. However, there is no agreement yet on how much money should be paid in, by whom, and on what basis.

Much more worryingly, there had been a push to phase out all fossil fuels by countries including some of the biggest producers: the EU, Australia, India, Canada, the US and Norway. However, with China, Russia, Brazil, Saudi Arabia and Iran pushing back, several commitments made at COP26 in Glasgow were dropped, including a target for global emissions to peak by 2025. The outcome was widely judged a failure on efforts to cut emissions: the final agreed text from the summit makes no mention of phasing out fossil fuels and scant reference to the 1.5℃ target.

Laurence Tubiana, one of the architects of the Paris Agreement, blamed the host country, Egypt, for allowing its regional alliances to sway the final decision, producing a text that clearly protects oil and gas petrostates and the fossil fuel industries.

The final outcomes demonstrate that, despite the thousands who were there to advocate for climate justice, it was the fossil fuel lobby that had most influence. As a climate justice scholar, I am deeply worried about the processes at COPs, especially given next year’s destination: Dubai. It remains to be seen what happens with the loss and damage fund, but time is running out and watered down commitments on emissions are at this stage deeply unjust and frankly dangerous.

The Horn of Africa has had years of drought, yet groundwater supplies are increasing – why?

Posted on November 7, 2022March 29, 2023 by janet.crompton

The Horn of Africa – which includes Somalia, Ethiopia, Kenya and some surrounding countries – has been hit by increasingly frequent and devastating droughts. Despite this, it seems the region has an increasing amount of groundwater. And this water could help support drought-stricken rural communities.

That’s the key finding from our new research, in which we discovered that while overall rainfall is decreasing, an increase in “high-intensity” rainfall has led to more water being stored deep underground. It’s a paradoxical finding, yet one that may help one of the world’s most vulnerable regions adapt to climate change.

In the Horn of Africa, rural communities live in a constant state of water scarcity punctuated by frequent periods of food insecurity. People there rely on the “long rains” between March and May and the “short rains” between October and December to support their lives and livelihoods.

As we write this, the region’s drylands are experiencing a fifth consecutive season of below-average rainfall. This has left 50 million people in acute food insecurity. The droughts have caused water shortages, livestock deaths, crop failures, conflict and even mental health challenges.

The drought is so severe that it is even affecting zebras, giraffes and other wildlife, as all surface waters are drying up and edible vegetation is becoming scarce. Worryingly, a sixth failed rainy season has already been predicted for March to May 2023.

Long rains down, short rains up

In a new paper we investigated changes in seasonal rainfall in the Horn of Africa over the past 30 years. We found the total rainfall within the “long rains” season is declining, perhaps related to the warming of a particular part of the Pacific Ocean. However, rainfall is increasing in the “short rains”. That’s largely due to a climate phenomenon known as the Indian Ocean Dipole, when a warmer-than-usual Indian Ocean produces higher rainfall in east Africa, similar to El Niño in the Pacific.

We then investigated what these rainfall trends mean for water stored below ground. Has it decreased in line with declining “long rains”, or risen due to the increasing “short rains”?

To do this we made use of a pair of satellites which orbit repeatedly and detect small changes in the Earth’s gravitational field that can be interpreted as changes in the mass of water storage. If there’s a significant increase in water storage underground, then the satellite will record a stronger gravity field at that location compared to the previous measurement, and vice versa. From this, the mass of water added or lost in that location can be determined.

Using these satellite-derived estimates, we found that water storage has been increasing in recent decades. The increase correlates with the increasing “short rains”, and has happened despite the “long rains” getting drier.

Given that the long rains deliver more seasonal rain than the short rains, we wanted to understand the paradoxical finding that underground water is increasing. A clue is given by examining how rainfall is converted into groundwater in drylands.

When rain is light and drizzly, much of the water that reaches the ground dampens the soil surface and soon evaporates back into the warm, dry atmosphere. To become groundwater, rainfall instead needs to be intense enough so that water will quickly infiltrate deep into the soil. This mostly happens when lots of rain falls at once and causes dry riverbeds to fill with water which can then leak into underground aquifers.

These most intense rainfall events are increasing in the “short rains”, in line with the overall increase in total rain in that season. And despite a decrease in overall rainfall in the “long rains”, intense rainfall has remained consistently high over time. This means that both rainy seasons have enough intense rainfall to increase the amount of water stored underground.

Finally, we demonstrated that the increasing water storage in this region is not connected to any rise in soil moisture near the surface. It therefore represents “banked” water that resides deep below ground and likely contributes to a growing regional groundwater aquifer in this region.

Groundwater can help people adapt to climate change

While early warning networks and humanitarian organisations focus on the urgent impacts of drought, our new research points to a silver lining that may support long-term climate adaptation. Those rising groundwater supplies we have identified may potentially be exploited to support people in rural areas whose food and water are increasingly insecure.

But there are some caveats. First, we have not assessed the depth of the available groundwater across the region, but we suggest that the water table is shallow enough to be affected by seasonal rainfall. This means it may also be shallow enough to support new bore holes to extract it. Second, we do not know anything about the quality of the stored groundwater and whether it can be deemed suitable for drinking. Finally, we do not know exactly what will happen if the most extreme droughts of the past few seasons continue and both long and short rains fail, causing intense rainfall to decrease too.

Nevertheless, our findings point to the need for extensive groundwater surveys across the Horn of Africa drylands to ascertain whether this increasing water resource may be viable enough to offset the devastating droughts. Groundwater could potentially irrigate fields and provide drinking water for humans and livestock, as part of a strategy to help this vulnerable region adapt to the effects of climate change.

Just Stop Oil: do radical protests turn the public away from a cause? Here’s the evidence

Posted on October 24, 2022March 29, 2023 by janet.crompton

Members of the protest group Just Stop Oil recently threw soup at Van Gogh’s Sunflowers in the National Gallery in London. The action once again triggered debate about what kinds of protest are most effective.

After a quick clean of the glass, the painting was back on display. But critics argued that the real damage had been done, by alienating the public from the cause itself (the demand that the UK government reverse its support for opening new oil and gas fields in the North Sea).

Supporters of more militant forms of protest often point to historical examples such as the suffragettes. In contrast with Just Stop Oil’s action, when the suffragette Mary Richardson went to the National Gallery to attack a painting called The Rokeby Venus, she slashed the canvas, causing major damage.

However, many historians argue that the contribution of the suffragettes to women getting the vote was negligible or even counterproductive. Such discussions often seem to rely on people’s gut feelings about the impact of protest. But as a professor of cognitive psychology, I know that we don’t have to rely on intuition – these are hypotheses that can be tested.

The activist’s dilemma

In one set of experiments researchers showed people descriptions of protests and then measured their support for the protesters and the cause. Some participants read articles describing moderate protests such as peaceful marches. Others read articles describing more extreme and sometimes violent protests, for example a fictitious action in which animal rights activists drugged a security guard in order to break into a lab and remove animals.

Protesters who undertook extreme actions were perceived to be more immoral, and participants reported lower levels of emotional connection and social identification with these “extreme” protesters. The effects of this kind of action on support for the cause were somewhat mixed (and negative effects may be specific to actions that incorporate the threat of violence).

Overall, these results paint a picture of the so-called activist’s dilemma: activists must choose between moderate actions that are largely ignored and more extreme actions that succeed in gaining attention, but may be counterproductive to their aims as they tend to make people think less of the protesters.

Activists themselves tend to offer a different perspective: they say that accepting personal unpopularity is simply the price to be paid for the media attention they rely on to “get the conversation going” and win public support for the issue. But is this the right approach? Could activists be hurting their own cause?

Hating protesters doesn’t affect support

I’ve conducted several experiments to answer such questions, often in collaboration with students at the University of Bristol. To influence participants’ views of protesters we made use of a well-known framing effect whereby (even subtle) differences in how protests are reported have a pronounced impact, often serving to delegitimise the protest.

For example, the Daily Mail article reporting the Van Gogh protest referred to it as a “stunt” which is part of a “campaign of chaos” by “rebellious eco-zealots”. The article does not mention the protesters’ demand.

Our experiments took advantage of this framing effect to test the relationship between attitudes to the protesters themselves and to their cause. If the public’s support for a cause depends on how they feel about the protesters, then a negative framing – which leads to less positive attitudes toward protesters – should result in lower levels of support for the demands.

But that’s not what we found. In fact, experimental manipulations that reduced support for the protesters had no impact on support for the demands of those protesters.

We’ve replicated this finding across a range of different types of nonviolent protest, including protests about racial justice, abortion rights and climate change, and across British, American and Polish participants (this work is being prepared for publication). When members of the public say, “I agree with your cause, I just don’t like your methods,” we should take them at their word.

Decreasing the extent to which the public identifies with you may not be helpful for building a mass movement. But high publicity actions may actually be a very effective way to increase recruitment, given relatively few people ever become activists. The existence of a radical flank also seems to increase support for more moderate factions of a social movement, by making these factions appear less radical.

Protest can set the agenda

Another concern may be that most of the attention obtained by radical actions is not about the issue, focusing instead on what the protesters did. However, even where this is true, the public conversation opens up the space for some discussion of the issue itself.

Protest plays a role in agenda seeding. It doesn’t necessarily tell people what to think, but influences what they think about. Last year’s Insulate Britain protests are a good example. In the months after the protests began on September 13 2021, the number of mentions of the word “insulation” (not “Insulate”) in UK print media doubled.

Colin Davis, Author provided

Some people don’t investigate the details of an issue, yet media attention may nevertheless promote the issue in their mind. A YouGov poll released in early June 2019 showed “the environment” ranked in the public’s top three most important issues for the first time.

Pollsters concluded that the “sudden surge in concern is undoubtedly boosted by the publicity raised for the environmental cause by Extinction Rebellion” (which had recently occupied prominent sites in central London for two weeks). There’s also evidence that home insulation has risen up the policy agenda since Insulate Britain’s protests.

Dramatic protest isn’t going away. Protagonists will continue to be the subject of (mostly) negative media attention, which will lead to widespread public disapproval. But when we look at public support for the protesters’ demands, there isn’t any compelling evidence for nonviolent protest being counterproductive. People may “shoot the messenger”, but they do – at least, sometimes – hear the message.

Climate change will not impact everyone the same way; but we do not know how

Posted on October 18, 2022March 29, 2023 by janet.crompton

Climate change is affecting the lives of billions of people. The impacts range from water scarcity and food production to health and wellbeing. Climate change impacts are felt in the cities and settlements where people live. We have heard many times that we need to ensure no one is left behind in climate change adaptation and mitigation. To ensure that every voice matters, the impacts of climate change on different groups have to be taken into account. Many individuals or groups are disproportionately affected by climate change as they have less capacity to prepare for, respond to, and recover from climate-related hazards. Worldwide, there are more than one billion persons with disabilities, 15% of the world’s population. The preamble of the Paris Agreement states that parties should respect, promote and consider their respective obligations on human rights and the rights of persons with disabilities, when taking action to address climate change.

Hence, IPCC working group II (WGII) 6th assessment report which was released earlier this year emphasizes not only the warming, drought and floods, but also how much we are exposed to these hazards. There is a renewed focus on vulnerability to climate change which varies strongly between regions and groups of people.

Germany currently holds the G7 presidency, an inter-governmental political forum consisting of several large global north industrial nations. The German Federal Government Commissioner for the Interests of the Disabled called for an Inclusion summit, the first of its kind, in September in Berlin. The main aim was to address questions around impacts of COVID-19, Artificial Intelligence, and climate change on persons with disabilities.

I have never before taken part in such an event, and it was a steep learning curve. Not only were there bilateral meetings between nations, but also the Internal Disability Alliance (IDA), had bilateral meetings with the academics who were invited to speak. The presentations were translated to international sign language, subtitled, and we implemented guidance to make these more accessible. Presenting to a group where many of the participants had visual impairments is different to the typical presentations a natural scientist is focusing on.

The climate change research was presented by Sebastien Jodoin (from McGill) and myself. Sebastien focused on the lack of inclusion of disability rights in the climate emergency. Fewer than one in four countries mentioned disabled people in their national climate plans. My contribution focused on pointing out the lack of knowledge on impacts of and adaptation to climate change in the context of persons with disability. The limited research in the climate change context focusses on heat and other extreme events. Vulnerability to climate change of persons with disabilities is not covered in the literature and therefore not assessed in the report. Disability is therefore only discussed as a category of vulnerability, as part of lists of old people, young people, marginalized and disabled. But these groups have different challenges and vulnerabilities.

So what was the outcome? IDA emphasized the importance of inclusion as a driver for change. The Chairs summary emphasized the importance of comprehensive statistical and research data to inform the design of policy aiming to identify and address barriers faced by persons with disabilities in exercising their rights.

Environmental justice ensures that socially vulnerable segments of the population should not be disproportionately affected by adverse environmental impacts or hazards. Often actions start at a local scale. In Bristol the Bristol Disability and Equality Forum is working towards inclusion on the city scale, based on their community climate action plan. Emma Green, their climate action coordinator, helped me to consider costs and benefits of climate adaptation more broadly than I did before. Environmental justice asks us all to make sure we consider the needs of everyone while we adapt to and mitigate to climate change. Subregional disaggregation will allow us to determine groups who have the information, skills and funds to implement climate adaptation and reduce their vulnerability, and those who will need support.
