EXTREME weather, driven by climate change, hit every populated continent in the world in 2019, killing, injuring and displacing millions of people and causing billions of dollars of damage, according to a new report.

Counting the Cost 2019: a year of climate breakdown, from Christian Aid, identifies 15 of the most destructive droughts, floods, fires, typhoons and cyclones of the past year, each of which caused damage of more than $1 billion (£769m).

The report said several of the figures were likely to be underestimated as some included only insured losses and did not take into account lost productivity and uninsured losses.

It said the billion-dollar disasters were linked with human-caused climate change which, in some cases, made the particular event more likely or stronger, for example with Cyclone Idai in Africa. In others, the event was the result of shifts in weather patterns – like higher temperatures and reduced rainfall that made fires more likely or warmer water temperatures that supercharged tropical storms. The most financially costly disasters were wildfires in California, which caused $25bn (£19.2bn) in damage. Floods in Northern India, which killed 1900, caused the greatest loss of life.

Dr Adelle Thomas, director of the Climate Change Research Centre at the University of the Bahamas and one of the lead authors of the Intergovernmental Panel on Climate Change’s sixth assessment report, said: “In small island developing states, such as The Bahamas where I’m from, we’ve experienced first-hand the repeated devastation caused by the climate crisis.

“Most recently, the record-breaking Hurricane Dorian destroyed lives, livelihoods and our sense of security. This was unfortunately not an isolated event, as multiple hurricanes in recent years have resulted in unprecedented devastation throughout the Caribbean region.”

Sally Foster-Fulton, head of Christian Aid Scotland, added: “In the year that Scotland signed one of the world’s most ambitious climate change acts, this report is a stark reminder about the urgency of climate action.”
