Greenhouse gases projected to sharply increase extreme flooding in Central Himalayas

Rising #GreenhouseGas #emissions could see the size of extreme f#loods in the Central #Himalaya's increase by between as much as 73% and 84% by the end of this century.

Geographers at Durham University, UK, simulated the risk of increased flooding on the Karnali River, which spans #Nepal and #China and has the potential to impact communities in Nepal and #India.

They found that extreme floods—those with a 1% chance of happening within a year—could increase in size by 22% and 26% between 2020 and 2059, compared to flooding seen in the region between 1975 and 2014.

This increase is expected to be 37–43% between 2060 and 2099 with medium greenhouse gas emissions. High greenhouse gas emissions could see the size of extreme floods increase by between 73% and 84% in the same period.
