Climate change is a reality and extremely high temperatures have been reported by India and Pakistan in the spring. In a new scientific journal article, researchers from the University of Gothenburg, amongst others, paint a gloomy picture for the rest of the century. Heat waves are expected to increase, affecting up to half a billion people every year. In turn, they can lead to food shortages, deaths and refugee flows when the heat reaches levels that exceed what humans can tolerate. But this does not have to happen if measures are put in place to reach the Paris Agreement targets, the researchers say.
In India and Pakistan, heat waves with temperatures above 40 degrees in the shade are a directly life-threatening form of extreme weather. In a new article in the journal Earth’s Future, researchers have outlined different scenarios for the consequences of heat waves in South Asia to the year 2100.
“We established a link between extreme heat and population. In the best scenario, we succeeded in meeting the targets in the Paris Agreement, which added roughly two heat waves per year, exposing about 200 million people to the heat waves. But if countries continue to contribute to the greenhouse effect as they are still doing now, clearing and building on land that is actually helping to lower global temperatures, we believe that there could be as many as five more heat waves per year, with more than half a billion people being exposed to them, by the end of the century,” says Deliang Chen, Professor of Physical Meteorology at the University of Gothenburg and one of the authors of the article.
