Secretary-General's Call to Action on Extreme Heat
Crippling heat is everywhere. Billions of people around the world are wilting under increasingly severe heatwaves driven largely by a fossil-fuel charged, human-induced climate crisis. – 2.4 billion people – are now at high risk of extreme heat. The most vulnerable communities are hit hardest.
In response to the rapid rise in the scale, intensity, frequency and duration of extreme heat, UN Secretary-General António Guterres on 25 July 2024 called for an urgent and concerted effort to enhance international cooperation to address extreme heat in four critical areas:
Caring for the vulnerable - Protecting workers - Boosting resilience of economies and societies using data and science - Limiting temperature rise to 1.5°颁 by phasing out fossil fuels and scaling up investment in renewable energy.
Secretary-General's remarksStrengthening Global Action
The UN Secretary-General's Call to Action on Extreme Heat brings together the diverse expertise and perspectives of ten specialized UN entities (FAO, ILO, OCHA, UNDRR, UNEP, UNESCO, UN-Habitat, UNICEF, WHO, WMO) in a first-of-its-kind joint product, underscoring the multi-sectoral impacts of extreme heat.
Call to Action"Extreme heat is having an extreme impact on people and planet. The world must rise to the challenge of rising temperatures."
ANT?NIO GUTERRES, United Nations Secretary-General (25 July 2024)
