People everywhere are struggling with the fatal impacts of worsening extreme heat, which is also damaging economies, widening inequalities and undermining green development, U.N. Secretary-General António Guterres said on Thursday. 

Calling for global action to limit the devastating consequences, the head of the United Nations said “billions of people are facing an extreme heat epidemic – wilting under increasingly deadly heatwaves”.

Extreme-heat events have been getting more frequent, intense and longer-lasting in recent decades as a result of human-made climate change.

Guterres’ appeal comes as the record for the world’s hottest day was set twice on consecutive days this week, according to Europe’s Copernicus Climate Change Service. Monday beat Sunday, with the global average surface air temperature reaching 17.15 Celsius, as parts of the world sweltered through fierce heatwaves from the Mediterranean to Russia and Canada.

Guterres said the UN had just received preliminary data indicating that Tuesday “was in the same range”, which would make a third hottest straight day on record, if confirmed.

In a speech, he noted that heat – driven by “fossil fuel-charged, human-induced climate change” – is estimated to kill almost half a million people a year, about 30 times more than tropical cyclones.

This year alone, extreme heat struck highly vulnerable communities across the Sahel region, killed at least 1,300 pilgrims in Mecca during Hajj and shut down schools across Asia and Africa affecting more than 80 million children.

“And we know it’s going to get worse. Extreme heat is the new abnormal,” Guterres added in his speech to journalists at UN headquarters in New York.

The Secretary-General’s “call for action” brings together ten specialised UN agencies for the first time in an urgent and concerted push to strengthen international cooperation in addressing extreme heat.

Focus on most vulnerable

Guterres listed four areas where greater efforts could be made to keep people, societies and economies safer from the negative consequences of rising global temperatures.

He emphasised the importance of “caring for the most vulnerable” – with those at greatest risk including poor people in urban areas, pregnant women, people with disabilities, the elderly, children, those who are sick and people who are displaced from their homes.

Households living in poverty often live in substandard homes without access to cooling, he added, appealing for a boost in access to low-carbon cooling and expanded use of natural measures – which include planting trees for shade – and better urban design, alongside a ramp-up of heat warning systems.

Workers also need more protection, he said, as a new report from the International Labour Organization warned that over 70 percent of the global workforce – 2.4 billion people – are now at high risk of extreme heat, especially in Asia-Pacific, Africa and the Arab States.

The UN is calling on governments to urgently review laws and regulations on occupational safety and health to integrate provisions for extreme heat, including the right to refuse working in extreme hot weather.

Energy transition and adaptation

A third area targeted by the UN for action is making economies and societies better able to withstand heat, through stronger infrastructure, more resilient crops, and efforts to ease the pressure on health systems and water supplies.

“Countries, cities, and sectors need comprehensive, tailored Heat Action Plans, based on the best science and data,” Guterres said.

Lastly, the UN chief urged stepped-up action to “fight the disease”, by phasing out fossil fuels “fast and fairly” including no new coal projects, with the aim of limiting global warming to 1.5C – a goal nearly 200 governments signed up to in the 2015 Paris Agreement.

“I must call out the flood of fossil fuel expansion we are seeing in some of the world’s wealthiest countries,” he emphasised. “In signing such a surge of new oil and gas licenses, they are signing away our future.”

The United States, Canada, Australia, Norway and the UK have issued two-thirds of the global number of oil and gas licences since 2020, according to research published by the International Institute for Sustainable Development this week.

‘Still time to act’

Commenting on the UN’s call to action, Alan Dangour, director of climate and health at Wellcome, a UK-based science foundation, noted that people working outside in physical jobs and those who cannot afford to adapt to rising heat are particularly exposed – but the effects are far broader.

“The levels of heat we now routinely see around the world put every part of society under extreme pressure, directly harming our health while also affecting food and water security and much of our vital infrastructures,” he said in a statement.

Speaking to journalists on Thursday, scientists convened by Wellcome said there are positive measures that can be taken to combat the problem of extreme heat, which can also bring wider social benefits.

For example, they explained that using community facilities as cooling centres can offer older people a place to chat or play cards, tackling social isolation and heat stress at the same time. Or adding shades with solar panels to market stalls can help women traders keep working on hot days while also providing free electricity for their businesses.

“There is still time for concerted action to save lives from the impacts of climate change, but we can no longer afford to delay,” Dangour said.

The UN’s call for action points out that existing tools to reduce the devastating consequences of extreme heat could be deployed with large and far-reaching effects. Guterres said the good news is that “there are solutions… that we can save lives and limit its impact”.

For example, a global scale-up of heat health warning systems could save more than 98,000 lives every year, according to the World Health Organization. And the rollout of occupational safety and health measures could avoid $361 billion a year in medical and other costs, the ILO has estimated.

The UN chief urged a “huge acceleration of all the dimensions of climate action” as global warming is currently outpacing efforts to fight it. That could start to change, he added, as heatwaves, impacts on public health and disasters such as Canada’s wildfires are now hitting the richest countries as well as poorer ones.

“The heat is being felt by those that have decision-making capacity – and that is my hope,” he said.

Santa Marta was a learning moment for how to shape inclusive just transitions

Published

on

Hina West is managing director of Climate Strategies.

The first Global Conference on Transitioning away from Fossil Fuels, organised by Colombia and the Netherlands, in Santa Marta late last month convened nearly 60 countries, as well as activists, Indigenous peoples, the private sector and academia. The aim of this historic event was to build a “coalition of the willing” driving action for fossil fuel phase-out beyond the UN climate process.

The stakes could not have been higher. As the planet grapples with catastrophic warming, economic instability and geopolitical conflicts fuelled by fossil fuel dependence, this conference represented a rare opportunity to reshape global energy governance, putting science and justice at the core.

For decades, fossil fuel phase-out has been the elephant in the room at climate COPs. Now is finally the time to have this conversation, with Santa Marta as the starting point.

So, what’s needed for this process to succeed? In the days preceding the political conference, all the different social group chapters – including academia, labour, private sector, civil society and Peoples (including Indigenous Peoples, Afro-descendant Peoples, peasants, frontline collectives and youth, among others) – developed ambitious recommendations to inform this new multilateral process.

As one of the co-hosts of the academic dialogue, I have learned a clear lesson on what is needed for Santa Marta to create actual breakthroughs for the global energy transition.

Looking where it matters

As someone working at the climate science-policy interface, I believe that science-based evidence is a crucial pathway towards implementing just, orderly and equitable transitions away from fossil fuels.

Yet, as Santa Marta convened colleagues from all over the world, we heard a clear call from representatives of regions directly impacted by the fossil fuel economy: We are over-diagnosed. The evidence is all here, and what we need now is action.

This is a humbling call for the research community: while we remain committed to the creation of knowledge, how can we ensure that these efforts lead to practical outcomes?

As we explored within the academic dialogue ahead of and at Santa Marta, international support for Just Transitions does not often strengthen the capacity of local actors (who are at the frontline) to develop and deliver just transition strategies. If the Santa Marta process wants to translate high-level commitments into credible and effective transition strategies, it must address this gap.

    Our discussion created a series of recommendations to address the challenge. Among them, we see the need for stronger collaborative governance across all scales and regions – from the global to the local and including South-to-South partnerships – that explicitly supports the local delivery of transition pathways. This is a gigantic task, made harder by the limited resources available.

    Today, climate finance remains systematically skewed towards technical and infrastructural investment, at the expense of social and justice programmes. Current regulatory frameworks and investment criteria must be redesigned so that following Just Transition goals brings financial returns, to ensure that resources are directed where they are most needed. Grant-based mechanisms and highly concessional finance must also be strengthened.

    Social dialogue and public participation

    Local communities and livelihoods must be placed at the centre of this process, to ensure that interventions are inclusive, aligned with territorial development strategies, and comprehensively address transition impacts (including informal and gendered work).

    This requires strong mechanisms for social dialogue and public participation, to be established early on and maintained throughout the implementation of Just Transition strategies. These can take different forms, such as legally binding participation frameworks, public interest committees and community-led advisory bodies.

    Grassroots communities must be recognised as co-producers of knowledge, not as consultees or receivers of information. This is also applicable to the Santa Marta process.

    Climate scientists call for fossil fuel transition roadmaps

    An expected highlight of this conference was the inclusion of underrepresented groups, including subnational governments, frontline communities, and Indigenous Peoples. Their active participation is crucial to ensure that the transition strategies discussed are not just technically sound, but socially just and locally relevant. These voices must be at the heart of the conference’s final outcomes.

    Nevertheless, Santa Marta was only the starting point of this ambitious multilateral process, and also in itself, not free from controversies. The transition away from fossil fuels will bring many uncertainties which require continuous learning and adaptation.

    What next?

    Taking a ‘build the ship as we sail it’ approach to this new layer of cooperation did not come without friction – be it from balancing Global South and North representation and short input deadlines, to knowing who had charge of the pen before, during and after the creation of our chapter’s output report, intended to feed into the subsequent high-level segment.

    I believe that robust, inclusive and context-specific analysis is essential for Just Transition planning and implementation. But as the expert community, we must provide this with solidarity, humility, and willingness to learn from those at the frontline of the transition.

    Many learnings surfaced regarding methodology and decision-making, and enhancing overall transparency and inclusivity for the next pre-science convening (and the broader event), currently mooted to be happening in Ireland, with the diplomatic gathering in Tuvalu, at some point next year.

    As we look towards the multilateral milestones ahead – Bonn, Tuvalu, Antalya – the message from Santa Marta is clear. This international momentum must be laser-focused on ensuring practical outcomes on the ground.

    What we need now is not another layer of dialogue or more diagnosis, but concrete action: binding and consistent commitments, robust and accountable governance, and finance that prioritises people and the planet. The future we want is within reach, and we have more than enough evidence to demonstrate it, but we need our resources and efforts to be aligned where it matters.

    Wyoming’s Largest Utility Joins a New Western Day Ahead Market for Electricity

    Published

    on

    Access to more power producers over a wider range of the West could lower rates, but Wyoming regulators will monitor the market to see if it penalizes the state’s coal, oil and gas over the next five years.

    Wyoming’s largest utility today began participating in a new “Extended Day Ahead Market” for electricity on the Western grid, a potentially landmark shift in the way energy is sold in the state that could lower rates as energy costs soar.

    Trump Pushes ‘Peace Pipelines’ to Boost Exports of Climate-Busting LNG to Europe

    Published

    on

    Exporting LNG overseas takes a massive environmental toll, generating huge amounts of greenhouse gases and pollution. It also increases natural gas prices, as many Americans struggle to pay rising energy bills.

    In the midst of a war in Iran and skyrocketing energy prices at home, the Trump administration is pushing to boost sales of U.S. liquefied natural gas across Central and Eastern Europe.
