Ganges flow could double at 2 degrees C global warming

 London, April 2: Examining how climate change could raise food insecurity risk across the world, researchers have projected that the flow of the Ganges river could more than double at 2 degrees Celsius global warming, with floods putting food production at risk in countries like India. “Climate change is expected to lead to more extremes of both heavy rainfall and drought, with different effects in different parts of the world,” said study co-author Richard Betts, Professor at the University of Exeter in Britain. “Such weather extremes can increase vulnerability to food insecurity,” Betts added.

The study looked at the difference between global warming of 1.5 degree Celsius and 2 degree Celsius (compared to pre-industrial levels). The findings showed that despite increased vulnerability to food insecurity in both scerios – the effects would be worse for most countries at 2 degrees Celsius. “Some change is already uvoidable, but if global warming is limited to 1.5 degree Celsius, this vulnerability is projected to remain smaller than at 2 degrees Celsius in approximately 76 per cent of developing countries,” Betts added.
