In response to the India Meteorological Division (IMD), the final 4 many years have been considerably hotter than earlier durations since 1850. Citing the Intergovernmental Panel on Local weather Change (IPCC) report of 2021, the IMD stated world floor temperatures between 2011 and 2020 have been round 1.09 levels Celsius increased than throughout 1850-1900.
The IMD has additionally famous that heatwaves have grow to be extra frequent and intense throughout many areas for the reason that Fifties.
In India, the annual imply floor temperature confirmed a warming pattern of round 0.62 levels Celsius per 100 years between 1901 and 2020, in line with IMD information.
