Climate change has made extreme rainfall events similar to those that led to last month’s floods in Germany, Belgium, the Netherlands and Luxembourg between 1.2 and 9 times more likely to happen, according to a rapid attribution study by an international team of climate scientists, which also found that such downpours in the region are now 3-19% heavier because of human-caused warming.

Climate change has accentuated natural hazards, including flash floods caused by melting of snow and ice in many regions of the world. The Himalayas, which are the third largest deposit of ice and snow in the world after Antarctica and the Arctic, are heavily impacted. This was highlighted by a disaster in February in Uttarakhand in the Indian Himalayas, after a part of the Nanda Devi glacier broke off and collapsed causing a massive flood in the Rishi Ganga /Dhauliganga river. This destroyed two hydropower plants, burst open dams, and led to a large number of casualties and widespread...
