CSTEP’s latest report, ‘Climate Atlas of India’, summarises the findings from historical climate analysis and makes future climate projections.
Here are the key findings:
-
The historical climate data was gathered for the period 1990-2019 from the Indian Meteorological Department (IMD) while the projections have been made for the next 30 years, 2021-2050 at a district level for the 28 states of India.
-
Climate change projections have been done for two representative concentration pathways (RCPs) or climate scenarios: RCP 4.5 (moderate #emissions scenario) and RCP 8.5 (high emissions scenario). Under both scenarios, a warmer and wetter future is projected for India.
-
An increase in maximum temperature by 1.5℃ to 2℃ is projected for 15% of the districts under the moderate emissions scenario and for 63% of the districts under the high emissions scenario.
-
An increase in the number of days with temperature departure from the normal by 4.5°C to 6.4°C and >6.4°C is projected under both climate scenarios compared to the historical period in all the 15 districts analysed for heatwaves.
-
Additionally, very high-intensity rainfall events are projected to increase by one to two events annually under the moderate emissions scenario and one to three events under the high emissions scenario.
