António Guterres calls extreme heat “the new abnormal” as he urges countries to step up protection of vulnerable populations
People everywhere are struggling with the fatal impacts of worsening extreme heat, which is also damaging economies, widening inequalities and undermining the world’s development goals, 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 broken 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 17.16 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.
