S Asia - Future super cyclones would expose many in most vulnerable locations to extreme flooding

A new study has revealed super cyclones, the most intense form of tropical storm, are likely to have a much more devastating impact on people in South Asia in future years.

The international research, led by the University of Bristol, looked at the 2020 Super Cyclone Amphan -- the most costly cyclone to make landfall in South Asia -- and projected its consequences in different scenarios of sea level rise due to global warming.

Its findings, published today in the Royal Meteorological Society journal Climate Resilience and Sustainability, showed if the release of greenhouse gases into the atmosphere continues at the same scale, more than two and a half times (250%) the population in India would experience flooding of greater than 1 metre, compared to the event in 2020.

Lead author Dann Mitchell, Professor of Climate Science at the University of Bristol, said: "South Asia is one of the most climate-sensitive regions in the world, with super cyclones causing tens to hundreds of thousands of deaths in historical cases. Comparatively, very little climate impact research has been done in South Asia, despite the Intergovernmental Panel on Climate Change highlighting it as such a critical region.
