Study: Extreme Heatwaves May Occur Annually by 2040 in Africa
Periods of unusually hot weather are on the rise in Africa and may become a normal occurrence in 20 years, which could have a damaging effect on life expectancy and crop production in the continent, a new study has warned. This scenario could be triggered by an increase in average global temperature of 2 degrees, said researchers who examined temperature data from 1979 to 2015. Located between the Tropic of Cancer and the Tropic of Capricorn, Africa experiences high levels of solar radiation all year round and heat waves can occur in any season, not just during summer months. Running climate models through to 2075, scientists found that so-called unusual heat waves could occur as frequently as four times per year towards the end of the century.
