Forecasting model from IITM, Pune, says heat waves likely to be three or four times higher

India’s first ever national forecast on the impact of global warming on the subcontinent in the coming century, expects annual rainfall to increase, along with more severe cyclones and — paradoxically — more droughts.

These projections, based on a climate forecasting model developed at the Indian Institute of Tropical Meteorology (IITM), Pune, will be part of the next report of the Intergovernmental Panel on Climate Change (IPCC), expected to be ready in 2022.

From 1986-2015, the hottest day and coldest night have warmed 0.63°C and 0.4°C, respectively. By the end of the 21st century, the report says, these temperatures are projected to rise by approximately 4.7°C and 5.5°C, respectively, relative to the corresponding temperatures in 1976-2005. This under a hypothetical scenario where no steps are taken to curb global greenhouse gas emissions or the RCP8.5 as it is called.

Currently countries have signed an agreement to reduce emissions to restrict global temperature rise by the end of the century to less than 2°C.
