Eight ways climate change is making the world more dangerous
Forget the future. The world already is nearly five times as dangerous and disaster prone as it was in the 1970s, because of the increasing risks brought by climate change, according to a new report from the World Meteorological Organisation.
The first decade of the 21st century saw 3,496 natural disasters from floods, storms, droughts and heat waves. That was nearly five times as many disasters as the 743 catastrophes reported during the 1970s – and all of those weather events are influenced by climate change.
The bottom line: natural disasters are occurring nearly five times as often as they were in the 1970s. But some disasters – such as floods and storms – pose a bigger threat than others. Flooding and storms are also taking a bigger bite out of the economy. But heat waves are an emerging killer.
Flooding and mega-storms were by far the leading cause of disaster from 2000-2010. About 80% of the 3,496 disasters of the last decade were due to flooding and storms. Seas are rising because of climate change. So are extreme rain storms. There is growing evidence that warming temperatures are increasing the destructive force of hurricanes.
Heat waves didn’t even register as a threat in the 1970s. By 2010, they were one of the leading causes of deaths in natural disasters, along with storms. In Russia alone, more than 55,000 people died as a result of heat wave in 2010.
Disasters were about 5.5 times more expensive by 2010 than they were in the 1970s, and most of that was because of the rising losses due to floods. The cost of disasters rose to $864bn (£505bn) in the last decade.
