Throughout recent weeks, Europe has yet again experienced the deadly effects of record-breaking extreme heat. Hundreds of heat alerts were put in place across the continent, as temperatures soared to 46C in some regions – with school closures and outdoor working bans in some nations.

Here in the UK, England may have just experienced its hottest June on record, with close to 600 people estimated to have died during the hottest period. Droughts have been declared in the North West of England and Yorkshire following the driest spring in 132 years; and wildfires recently scorched the earth across Scotland, Dartmoor and the Peak District. The land area burnt so far this year is already the highest in over a decade.

On Monday, the latest State of the UK Climate report showed that the number of days with temperatures 5C above the 1961-1990 average has doubled since that period for the most recent decade from 2015-2024. According to the Met Office, the hottest days experienced in the UK have dramatically increased in frequency in just a few decades, while the last three years have been in the country’s top five warmest on record.

Not prepared for extreme weather

Government statistics show there were more than 10,000 heat-related deaths in the UK alone between 2020 and 2024. Close to 3,000 people died amidst the record-breaking 2022 heatwaves, when UK temperatures exceeded 40C for the first time.

Despite this, the UK remains unprepared for extreme heat. In April this year, stark warnings were issued by the national government’s official climate adviser, the Climate Change Committee (CCC): The country is “not prepared” for climate impacts, progress has been “inadequate”, “too slow”, or has “stalled”. Encompassing heat risks, the CCC reported that not a single outcome of UK climate adaptation shows signs of ‘good’ delivery.

Scientists hail rapid estimate of climate change’s role in heat deaths as a first

The British public agrees the nation isn’t ready. Climate Barometer polling finds that more than three quarters (78%) believe the UK is ‘not prepared’ to deal with climate impacts, including extreme weather. Just 16% say there has been ‘good progress’ when it comes to climate adaptation.

In 2023, over two-thirds of the public said both national and local governments in the UK are not prepared for extreme heat events. Alarmingly, this sentiment is shared by paramedics, fire fighters, decision makers and community leaders who worked on the frontline of the 2022 heatwave response.

A disjointed landscape of heat communication

With most heat-related deaths being preventable, the way we communicate plays a pivotal role in reducing impacts. But we urgently need to improve the landscape of heat risk communication.

In the UK, while updated heat warning systems have been welcomed, aspects of the public-facing communication may be inadequate or unclear in terms of encouraging action. More widely, media portrayals of heatwaves continue to show people having ‘fun in the sun’, despite research showing this undermines the severity of heat risks.

Comment: Early warnings for heatwaves can save lives – and we need them now

Across Europe, in the absence of strong leadership on heat, political narratives are quickly forming around the moral need for air conditioning rollouts – despite AC units being costly, energy intensive, and making urban heat worse.

This all has knock-on consequences. Recently published UK-wide survey research shows that less than half of respondents (46%) said they felt ‘well-informed’ about heat risks. Very few felt that national (27%) and local governments (18%) were doing a ‘good job’ of communicating heat risks, and 20% said they lacked confidence in the accuracy of media coverage (37% were unsure).

Communicating better about heat

To help improve this disjointed landscape, here are three key suggestions:

1 – Heat communications must draw on social research. Studies show a very wide range of factors influence our actions and vulnerabilities when it comes to heat. From our belief about the risks, to where we live, to our cultural heritage, and the actions of our friends and family – these factors all play a role in shaping heat-related behaviour. Taking stock of these influences, alongside an awareness of the unequal impacts of heat, is necessary to inform better communication approaches. Social research also highlights the need for active, inclusive engagement that goes beyond one-way messaging (e.g. locally-led projects to increase tree cover, or community decision making about heat-resilient neighbourhoods).

2 – A focus on advance preparation is sorely needed. Preparation for heat should occur “all year round”, but typically UK risks aren’t treated in this way, with media coverage spiking as the heat takes hold. A review of heatwave research found an overwhelming focus on ‘protective actions’ (e.g. using a fan or drinking water to stay cool during heatwaves), rather than ‘preparative actions’ (e.g. installing shutters and blinds, or improving shading). This is despite the latter typically bringing benefits for more than one person, by reducing household vulnerability. Instead of an overemphasis on short-term coping, we need to build longer-term heat resilience.

3 – Effort is needed to address heat perception gaps. There are well known vulnerability gaps when it comes to climate impacts. Research by the British Red Cross found that “those most vulnerable to the effects of extreme weather often have the lowest awareness of their risk and the least knowledge of how to prepare”. Similar ‘perception gaps’ have been found in relation to heat impacts. For instance, people tend to believe they are less vulnerable to heat impacts than others in their community. Many in the UK look forward to heatwaves, despite the risks. And more than a third think heatwaves will only be a problem for the UK in the future. Tackling perception gaps like these could help unlock community preparedness.

Better communication alone is not enough. This must go hand-in-hand with policy changes, regulation, planning, and coordination. But with extreme heat a “new normal”, the way governments, community leaders and the media communicate about extreme heat matters now more than ever.

The more that social research insights are taken onboard, ultimately the more lives could be saved.

How clean energy can boost business for Africa’s food producers

Published

on

Despite millions of dollars in grants and technical help for African businesses to power farming and other food production activities with renewable energy, most efforts remain stuck at the early stages because they struggle to find the investors, markets and expertise they need to grow.

This was the message from a coalition of global institutions working on energy, water and agriculture at this month’s Africa Food Systems Forum in Kigali, Rwanda.

“Energy, agriculture, water and nutrition actors rarely design solutions together,” the Agri-Energy Coalition said in a Call to Action on powering food systems with clean energy.

Using more renewables – especially solar power – to drive food systems would reduce food losses, ensure year-round availability and affordability of healthy foods, and improve productivity, income and resilience among farmers, food processors and other small enterprises, the coalition added.

In an interview with Climate Home News at the forum, Olamide Niyi-Afuye, CEO of the Africa Minigrid Developers Association (AMDA) – a body representing private-sector developers of small-scale, off-grid electricity systems across the continent – said its members are starting to recognise this interdependence and are increasingly considering businesses that combine energy with agricultural activities.

    This, Niyi-Afuye added, could lead to greater supply and use of clean power for key processes like irrigation, food processing and storage, creating new sources of revenue for both sectors.

    CHN: Conversations at the Africa Food Systems Forum highlighted how organisations working in energy and agriculture often operate in silos. What has hampered their collaboration, and how has that affected Africa’s economic development?

    A: Most mini-grid companies in Africa were primarily incentivised to achieve connections. If you look at some ongoing projects, you see a cost-per-connection model [of revenue]. When a subsidy is tied to achieving a connection, regardless of whether it is a productive connection, you might not notice the problem until five years down the line, when you realise the cash flows are not what you projected.

    Despite African walkout, fractious land COP ends without drought deal

    So now we’re in a “come-to-Jesus moment” as an industry, where we’re righting the wrongs and adjusting our business models to make sure companies do not go bust and there is some level of sustainability over the long term.

    The saying is not wrong that we’ve been working in our own silos because we’ve focused on the smaller things instead of the helicopter view. There needs to be cross-pollination [between the energy and agriculture sectors] because, if we are thinking about industrialisation, energy is a key driver of industrialisation. We will not achieve that if we’re not in the room and part of those conversations.

    CHN: Productive use of energy is intended to ensure electricity access goes beyond lighting homes to improving livelihoods, creating jobs and powering equipment. But what happens when farmers cannot afford the equipment they need to do that? How can energy, agriculture and equipment players work together to make the transition more accessible?

    A: That’s why we’re having conversations with companies set up to de-risk the agriculture sector. By leveraging that connection, we’re able to aggregate potential energy needs and develop instruments that make equipment more affordable through bulk procurement.

    We can have arrangements that make it easier for farmers and food producers to lease equipment and eventually own it over a period. There’s no real pressure to recover the capital very quickly because you’re looking at scale.

    There is a whole lot across the agricultural value chain that needs energy, from farming and harvesting to food processing and value-addition. We need to understand the energy needs across the value chain and bring our members in to provide solutions.

    Developers do not necessarily need to provide every productive-use solution themselves. They can partner with equipment suppliers, financiers, agribusinesses and other service providers to enable customers to use electricity productively. The objective is simple: do not just electrify communities; enable economic activity that uses that electricity.

    CHN: When Africa’s industrialisation is discussed, you hear things like renewables cannot provide enough baseload, while some food processors are sceptical about switching to renewable energy because of these concerns about reliability. What is your response?

    A: It’s not a controversial statement to say that a typical baseload is usually from the grid, and it’s usually from multiple sources including renewable energy. For large-scale operations, we can look at blending multiple sources of energy. But how do we solve the problem of a mid-sized farmer? We can solve it with a mini-grid using renewable energy.

    Comment: Every country needs a model to help optimise its energy transition

    If you go to a small farmer in a rural area, they don’t care about what source of energy they’re getting. They just want something that can help them get from A to B. If you look at the direct energy needs of farmers and food processors, I’m sure 90 percent of their consumption can be solved by renewable energy. Let’s start with that problem first. Then, as they scale, they might need to ramp up, and we can start talking about a bigger baseload.

    CHN: How much agricultural value is lost because farmers and food businesses lack reliable, affordable electricity?

    A: If you look at, for example, the fact that we need to maybe plant tomatoes or strawberries in Jos before it gets to Lagos [Nigeria], which most likely is by road, I can assure you that a good chunk, if not stored properly, would be bad by then. So the fact that we do not have energy is in itself a lost opportunity to maximise the potential of the agriculture sector. So until we’ve solved the energy problem, we will not salvage waste – and for me that is a lost opportunity.

    CHN: AGRA, an institution focused on scaling agricultural innovations to help smallholder farmers, estimates a massive shortfall between current investments in the continent’s food systems and what is actually needed to build a resilient, profitable agricultural economy – to the tune of $180 billion per year. Can integrating energy into food systems help bridge that gap?

    A: Yes – if energy can help unlock the potential to earn more money, investors will follow the money. Investments go where there is certainty, and until there is certainty around cash flow and revenue, investment will be limited.

    My vision is to see more Power Purchase Agreements (PPAs) being signed between energy players and the agriculture sector. We can start by getting people into the room, understanding their pain points, crafting a framework and documentation that works for both parties, and then seeing deals happen.

    Human security relies on adapting to the world’s new climate reality

    Published

    on

    Cristina Rumbaitis del Rio is a senior advisor on adaptation and resilience with the United Nations Foundation and Mattias Söderberg is global climate lead at Danish NGO DanChurchAid.

    Recent extreme events – from wildfires and heatwaves in Europe to flash flooding following a glacier collapse in Nepal – have shocked and devastated communities, bringing years of warnings about such climate impacts to the doorstep of communities around the world.

    One thing is certain: the new climate reality is here – and the adaptation strategies designed for yesterday’s world are no longer sufficient.

    Attribution science has since shown that the hotter and more frequent heatwaves we’re experiencing around the world would have been virtually impossible without today’s high concentrations of greenhouse gases in the atmosphere. Climate shocks are now so severe that they reverberate through supply chains, food and water systems, financial markets and the movement of people.

      They must be a catalyst for a new way of thinking about adaptation and resilience, and how we finance solutions that work. A failure to invest in adaptation in one region can create costs far beyond it, which is why the concept of shared resilience is critical for leaders to grasp.

      Investment not charity

      At the UN General Assembly (UNGA 81) this month, leaders have an opportunity to translate today’s urgency into concrete commitments on adaptation and loss and damage finance ahead of COP31.

      Those commitments are needed to underpin global stability, shared prosperity and human security. Governments should use this moment to show what a new response looks like: finance that reaches communities faster, supports locally grounded solutions, strengthens national systems, and helps countries prepare before the next shock arrives.

      If we want sustained economic growth, food and water security, and resilient and prosperous societies across every region, adaptation must be at the heart of today’s development and security agenda. It cannot be just a future planning consideration or a narrow issue for climate ministries. Adaptation is now everyone’s business – and it must be financed fast and fair.

      UN Secretary-General António Guterres has repeatedly framed climate finance as an investment rather than charity, warning that “a world in climate chaos cannot be a world at peace” and describing human security as freedom from the chronic and sudden disruptions that climate change multiplies.

      What’s more, adaptation delivers a real return-on-investment, with researchers estimating that every dollar invested produces $10 in benefits, saving lives, protecting livelihoods, and reducing the costs of future disasters.

      Hitting adaptation limits

      The urgency to scale adaptation systematically is growing. The newly released “Limiting Overshoot” report from the UN Environment Programme (UNEP) confirms what scientists have long warned: exceeding global warming of 1.5C is now unavoidable under current policies. Yet, how high temperatures rise – and how long the world remains above the 1.5C threshold – will determine whether communities, economies and entire ecosystems can keep pace.

      There are limits to adaptation. When we breach those limits, lives and livelihoods are lost, and people and ecosystems suffer greatly. We cannot simply build yesterday’s infrastructure a little stronger and assume it will be enough.

      Nepal flood destruction shows “limits to adaptation”, scientists say

      We need to fundamentally change the systems that determine how societies anticipate, absorb and recover from both immediate and evolving non-linear climate shocks. This includes transforming physical systems, such as infrastructure, and the governance systems that affect where and how we live to how we maintain our health and wellbeing.

      Finance today is nowhere near the scale of the challenge.

      The UNEP “Adaptation Gap Report 2025” estimates the shortfall in adaptation finance in developing countries at $284 billion–$339 billion a year – roughly 12 to 14 times current international public flows of around $26 billion. That gap is a development, economic and human security problem, especially for the most vulnerable populations who have contributed the least to causing the climate crisis.

      Building resilience into financial systems

      There are already signs of what a more systemic adaptation response could look like. Communities around the world are delivering practical solutions at local level, even as adaptation finance remains notoriously, and appallingly, difficult to access. Cyclone-resistant homes, local forecasting capacities, drought-resistant crops, heat insurance for pregnant informal workers and mangrove restoration are rooted in local knowledge and lived experience, while delivering benefits far beyond the communities where they originate from.

      But local innovation alone is not enough; the systems around it need to be resilient too.

      Jamaica offers one example. The country has built a multi-layered disaster-risk financing framework, including a catastrophe bond and contingency funds, through sustained fiscal discipline and proactive investment. Its debt-to-GDP ratio fell from around 147% in 2012 to around 62% in 202-25. That groundwork matters when disaster strikes.

      Hurricane Melissa’s destruction shows need for climate resilience push

      Following Hurricane Melissa, Jamaica was able to secure billions of dollars in reconstruction financing from multilateral banks – finance that might otherwise have been much harder to access. The lesson is clear: resilience can be built into the financial architecture of a country before a crisis arrives. That is the shift we now need to make at scale.

      The foundations already exist – in Kingston’s fiscal reforms, in early-warning systems from the Sahel to the Pacific, and in every community that adapted before disaster struck. What is still missing is the political will, and the finance, to take what works and put it to work everywhere, at the speed our world’s new climate reality demands.

      Framing the climate science debate as a binary battle isn’t just wrong – it’s dangerous

      Published

      on

      Lidy Nacpil is the coordinator of Asian Peoples’ Movement on Debt and Development (APMDD).

      Recent reporting on international climate negotiations has highlighted a sharpening divide within civil society and multilateral diplomacy. A troubling, simplistic narrative has taken root: that the UN climate process is witnessing a binary struggle between defenders of science and those attacking it.

      This framing is not only inaccurate; it is dangerous. Characterising a substantive methodological and political debate in these terms misdiagnoses the stakes and stirs conflict instead of clarity.

      No one disputes that climate action must rest on science. Science tells us what has led us to the climate crisis – the accumulation of historical emissions – and how much carbon budget remains if we are to keep temperature rise below 1.5C. It tells us how much global emissions must drop, and how fast. Science is also essential in assessing each country’s historical contribution to the accumulation of greenhouse gases in the atmosphere.

      Responsibility, however, must also be based on capacity. For those who generated the largest share of historical emissions, that capacity includes the enormous wealth and economic power accumulated through the same fossil-fuel-intensive development that generated those emissions.

      As science comes under attack at UN talks, climate movement splits over how to respond

      While principles that should guide human action aren’t scientific questions – they are matters of values – applying them to real-world problems requires scientific grounding. Equity recognises the scientifically established reality of differentiated responsibilities among countries and within societies. Putting equity into practice demands scientific rigour.

      Scrutiny of IPCC models

      Today, critics are scrutinising the assumptions and frameworks behind the Intergovernmental Panel on Climate Change’s Integrated Assessment Models (IAMs), used to project future scenarios and map global mitigation pathways. These concerns centre squarely on equity and justice.

      The economic, technological and policy assumptions used in IAM scenarios are normative choices rather than scientifically prescribed or neutral facts. These include choices about discount rates, economic growth, energy demand, technology costs, carbon prices, land availability and the regional location of mitigation. Many IAM scenarios reproduce existing global inequalities rather than transform them. Questions about transparency, representativeness and diversity in the scientific process are deeply urgent.

      Most IAM scenarios are built primarily around global cost-effectiveness – directing emissions reductions to places where mitigation is modelled as cheapest rather than allocating effort according to historical responsibility, capacity and development needs.

      The resulting pathways allow developed countries to retain disproportionately high levels of energy and fossil-fuel consumption while requiring developing countries to undertake substantial mitigation and carbon removal, including land-based measures that threaten food security and local development.

      Northern models often assume uniform access to cheap financing. In reality, Global South economies face far higher capital costs, driving up the price tag of rapid infrastructure shifts.

      Constraints on development space

      Scenario constraints also limit the development space poorer nations need without guaranteeing adequate climate finance. When models treat profoundly unequal starting points as uniform baselines, policy pathways lock in global inequality under the banner of scientific objectivity.

      Pointing out these structural flaws isn’t rejecting science. It is essential scientific scrutiny aimed at producing stronger, fairer, and more actionable results.

      Science ‘under attack’ from fossil fuel interests at UN climate talks

      The fight is not about whether we want to keep temperature rise below 1.5C, but about how we get there. A pathway can be technically compatible with 1.5C or 2C while still being deeply unequal in who gets to consume energy, who must reduce emissions, and whose development is constrained. Temperature compatibility alone does not make a pathway fair.

      Critiquing IAM scenarios from an equity perspective is neither an attack on the Intergovernmental Panel on Climate Change (IPCC) nor an attack on science. Rigorously examining IPCC reports – their substance, assumptions, and processes – is an acknowledgement of the IPCC’s importance and entirely consistent with scientific method.

      Tensions over AR7 timing

      There is a separate but related tension over the cycle and timeline of the IPCC’s Seventh Assessment Report (AR7). Some governments and civil society voices advocate completing its Working Group reports in time to feed directly into the UN’s Second Global Stocktake in 2028.

      The motivation makes sense: policymakers need timely science. But several developing-country negotiators and researchers have warned that meeting that deadline could severely disadvantage the Global South.

      Funding gap threatens next round of IPCC climate science reports, chair warns

      Global North authors and institutions remain disproportionately represented in the research underlying IAM assessments. Developing-country researchers often work with fewer institutional resources, smaller research budgets, and less administrative support. Accelerated publishing and assessment schedules can further limit their ability to generate, submit, and peer-review research in time for inclusion.

      The AR7 timeline concerns boil down to inclusivity, representation, and equity. Requiring the IPCC to meet tight political calendars without ensuring meaningful support and participation for developing-country researchers risks reproducing the very inequalities being challenged.

      Cooperation requires equity

      Political interests are indeed at work in UNFCCC negotiations and must be surfaced. Bad-faith actors seek to evade fossil-fuel phase-outs or shirk climate-finance obligations. Many developed country parties are guilty of both, including those who style themselves as “Friends of Science.”

      We must not lump legitimate scientific critiques raised by several Global South researchers and many civil society organisations concerning representation, economic assumptions and fair-share accounting together with obstructionism. Doing so risks misrepresenting and delegitimising critical scientific work and Global South equity and justice perspectives.

      The climate movement is strongest when it aligns rigorous science with global equity and justice. Achieving the Paris Agreement’s goals requires robust science that fully integrates the experiences, economic realities and academic contributions of the Global South. Effective climate action also requires international cooperation, and without equity, such cooperation cannot be sustained. We do not have to choose between science and equity. We need both.
