Another year of scorching temperatures from the Middle East to sub-Saharan Africa and from Europe to the Indian subcontinent has experts increasingly worried. If nothing is done to slow climate change, record-breaking temperatures and deadly heatwaves will only become more frequent and intense, research has shown. “Climate (change) is sort of steroids for the weather. It’s loading the dice to make these sort of extreme events be more common,” says Zeke Hausfather, a climate expert at the Breakthrough Institute in California. A recent study found that if the world keeps emitting at the same levels, in less than 30 years time some parts of the Middle East and North Africa will experience long periods of extreme heat of such magnitude that during these times life outdoors will be almost impossible to bear.
