It hasn’t been a good year for people concerned about climate change. The expected peak in carbon emissions has not appeared, meaning global warming continues to accelerate (see ‘Humans have warmed the planet by 1.5°C since 1700’). Meanwhile, Donald Trump’s election as US president for a second term and his pledge to “drill, baby, drill” new oil and gas supplies could lead the country to backtrack on climate action. expensive.
Similar sentiments against fossil fuels come from Azerbaijan’s President Ilham Aliyev, who called the oil-rich country’s natural resources a “gift from God.” Aliyev made the comments at the COP29 climate summit in Azerbaijan’s capital Baku. Ironically, this “gift” will become increasingly unavailable as a warming world dries up the Caspian Sea and strands billions of dollars in fossil fuel infrastructure. (See ‘We face climate disaster as the world dries up’).
Given the failure of politicians on the international stage to grasp the reality of climate change, other leaders need to step up, but surprisingly, mayors are the best suited to do so. Maybe it’s the position.
It will be essential for cities to adapt to cope with the unique impacts of urban heat.
Mayors cannot be expected to influence the Earth’s climate, but they oversee the well-being of more than 50 percent of the world’s population who live in urban centers. This number is expected to increase to 70 percent by 2050. Current projections are for spot temperatures to increase by 2.5 degrees Celsius. Adapting cities to deal with the unique effects of urban heat will be essential, from promoting green spaces to investing in buildings that can be cooled without air conditioning (‘Extreme heat makes cities uninhabitable’). (See “How can I survive?”)
The good news is that many mayors already recognize their responsibilities. London Mayor Sadiq Khan aims for the city to be net zero by 2030. Anne Hidalgo, the mayor of Paris, France, planted trees in certain areas and banned cars from passing. Los Angeles Mayor Karen Bass also pledged environmentally friendly changes in preparation for the 2028 Olympics. Organizations like C40 and Climate Mayors are helping to unite local politicians around the world into action. This won’t solve climate change, but it will make life in a warming world more bearable for many people.
