In March and April this year, heat waves hit South Asia, killing more than 90 people. According to a report, climate change has increased the risk of this heat wave by 30 times.
“Before the onset of human-induced climate change, such events occurred approximately once every 3,000 years,” scientist Friederike Otto told AFP in a report.
Autos and his colleagues from the World Weather Attribution (WWA) Consortium have observed that global warming of up to 1.2 degrees Celsius shortens the so-called return time for the same period and extreme heat in South Asia once a century. . In other words, the probability of such a heat wave is 30 times higher.
As global warming continues unabated, the gap between these deadly heat waves will shrink further.
The aforementioned report states that if the Earth’s average surface temperature rises another four-fifths of a degree to 2 degrees Celsius, this type of heat wave may occur once every five years.
Based on the current national commitment to reduce carbon emissions under the Paris Agreement, the world will experience global warming of 2.8 degrees Celsius.
Temperatures in India and Pakistan were higher than in March and April this year.
More than 90 deaths have been directly attributed to the heat wave, but this number could increase. It will take a few more months to calculate the total toll and economic loss, taking into account illness, lost wages, missed school days and reduced working hours.
