National academies say effects include spread of diseases and worse mental health

A report by experts from 27 national science academies has set out the widespread damage global heating is already causing to people’s health and the increasingly serious impacts expected in future.

Scorching heatwaves and floods will claim more victims as extreme weather increases but there are serious indirect effects too, from spreading mosquito-borne diseases to worsening mental health.

“There are impacts occurring now [and], over the coming century, climate change has to be ranked as one of the most serious threats to health,” said Prof Sir Andrew Haines, a co-chair of the report for the European Academies’ Science Advisory Council (Easac).

However, there were also great benefits from action to cut carbon emissions, the report found, most notably cutting the 350,000 early deaths from air pollution every year in Europe caused by burning fossil fuels. “The economic benefits of action to address the current and prospective health effects of climate change are likely to be substantial,” the report concluded.

The World Health Organization director general, Tedros Adhanom Ghebreyesus, warned in November that climate breakdown was already a health crisis. “We cannot delay action on climate change,” he said. “We cannot sleepwalk through this health emergency any longer.” In December, a WHO report said tackling the climate crisis would save at least a million lives a year, making it a moral imperative to act.
