Why in news
World Weather Attribution (WWA) reported that human-caused global heating increased the intensity of heavy rain in the Cyclone Senyar-affected region by 28-160%.
Background
The WWA study found that heavy rain periods in Sri Lanka are now 9% to 50% more intense due to climate change. These extreme weather events, including Cyclone Ditwah and Cyclone Senyar, resulted in over 1,750 deaths.
