DELHI and Mumbai's mean annual temperature will be five degrees Celsius higher in the 2080-2099 period as compared to the 1995-2014 period if global CO2 emissions double by 2050, according to Greenpeace India's new heatwave projections based on Intergovernmental Panel for Climate Change's sixth assessment report.

The national capital's annual maximum temperature (the median of June month record from 1995 to 2014) stands at 41.93 degrees Celsius.

It will leap to 45.97 degrees Celsius in the 2080-99 period and can go up to 48.19 degrees Celsius in "some extreme years", the NGO said in a report.

A recent heatwave in Delhi saw the maximum touching 43.5 degrees Celsius on April 29, which is well above the average maximum temperature for the month. An analysis of the historical daily temperature for April from 1970 to 2020 shows that only four years have recorded a value higher than 43 degrees Celsius, it said.

Mumbai's mean annual temperature will be five degrees Celsius higher in the 2080-2099 period as compared to the 1995-2014 period and the annual maximum temperature will increase from 39.17 degrees Celsius at present to 43.35 degrees Celsius, the report said.
