Because the period of “international boiling” spawns ever deadlier heatwaves, a handful of warmth tsars are working with officers in cities from Miami to Melbourne in a race in opposition to time to chill city warmth traps and forestall tens of 1000’s of deaths.
Seven chief warmth officers – who all occur to be girls – are working in Miami, Melbourne, Dhaka, Freetown and Athens to plant bushes, create “pocket parks”, set up water fountains and train individuals in regards to the results of excessive warmth on the human physique.
The function of chief warmth officer was created three years in the past by a US-based assume tank, however even in that brief time the duty has grow to be extra pressing as planet-heating emissions – largely from the usage of coal, oil and fuel – are pushing temperatures into “uncharted territory”, in line with scientists.
Already, final yr was the hottest on document, and new analysis means that the extraordinary northern hemisphere summer season warmth made it the warmest summer season in some 2,000 years – extra proof of what UN Secretary-Common António Guterres known as “the period of world boiling“.

The chief warmth officer posts had been created by means of an initiative by the US-based Adrienne Arsht-Rockefeller Basis Resilience Heart (Arsht-Rock), which says that by 2050, heatwaves will have an effect on greater than 3.5 billion individuals globally – half of them in city centres.
“Warmth is probably the most lethal local weather hazard. It’s a silent killer,” mentioned Elissavet Bargianni, who was appointed chief warmth officer for Athens in Might 2023.

Practically half of faculties and hospitals in European cities are situated in city “warmth islands” – areas which might be at the least 2 levels Celsius (3.6 levels Fahrenheit) hotter than the regional common, in line with the European Union’s atmosphere company.
