The damage caused by the climate crisis through extreme weather has cost $16m (£13m) an hour for the past 20 years, according to a new estimate.

Storms, floods, heatwaves and droughts have taken many lives and destroyed swathes of property in recent decades, with global heating making the events more frequent and intense. The study is the first to calculate a global figure for the increased costs directly attributable to human-caused global heating.

 

It found average costs of $140bn (£115bn) a year from 2000 to 2019, although the figure varies significantly from year to year. The latest data shows $280bn in costs in 2022. The researchers said lack of data, particularly in low-income countries, meant the figures were likely to be seriously underestimated. Additional climate costs, such as from crop yield declines and sea level rise, were also not included.

 

The researchers produced the estimates by combining data on how much global heating worsened extreme weather events with economic data on losses. The study also found that the number of people affected by extreme weather because of the climate crisis was 1.2 billion over two decades.

Two-thirds of the damage costs were due to the lives lost, while a third was due to property and other assets being destroyed. Storms, such as Hurricane Harvey and Cyclone Nargis, were responsible for two-thirds of the climate costs, with 16% from heatwaves and 10% from floods and droughts.

and yet governments IMO spend sod all on mitigation of extreme events.

The Japanese are the only ones I know of that have built sea defenses.
