Study Shows Record-breaking Heatwave in Madagascar Would’ve been “Virtually Impossible” without Human-caused Global Heating

The extreme temperatures affected millions of very poor people but the damage to their lives was not recorded by officials or the media. Many governments in Africa lack the capabilities to record climate impacts. The scientists behind the report said this lack of information made implementing measures to avoid deaths very difficult. The study linking the prolonged heatwave to the climate crisis was the first in sub-Saharan Africa and found temperatures were 2.5C higher than the recent average. Antananarivo, the capital of Madagascar and home to more than 3 million people, suffered some of the most unusual heat. If continued fossil-fuel burning pushes global temperature up to 2C above pre-industrial levels, this intensity of heatwave would be expected every five years, the researchers calculated. The new study was conducted by the World Weather Attribution group. The researchers used weather data and climate models to see how the intensity and frequency of heatwaves in Madagascar today compared with those before global heating pushed up the planet’s temperature.
