Temperature likely to increase by End of Century
Reportedly average temperature over india is projected to rise by 4.4 degrees Celsius, while the intensity of heat waves is likely to increase by 3 to 4 times by the end of the century, according to a government report on the impact of climate change on the country. India's average temperature has risen by around 0.7 degree Celsius during 1901-2018, largely on account of GreenHouse Gases-induced warming, states the report by the Ministry of Earth Sciences. Meanwhile the report has been prepared by the Centre for Climate Change Research, a cell under MoES' indian Institute of Tropical Meteorology, Pune. By the end of the twenty first century, average temperature over india is projected to rise by approximately 4.4 degrees Celsius.
Meanwhile in the 30 year period between 1986 and 2015, temperatures of the warmest day and the coldest night of the year have risen by about 0.63 degrees Celsius and 0.4 degree Celsius, respectively. By the end of the century, the temperatures of the warmest day and the coldest night are projected to rise by approximately 4.7 degrees Celsius and 5.5 degrees Celsius, respectively, according to the report. The frequencies of occurrence of warm days and warm nights are projected to increase by 55% and 70%.
Moreover the frequency of summer (April-June) heat waves over india is projected to be 3 to 4 times higher by the end of the twenty-first century, the report states.
The average duration of heat wave events is also projected to approximately double. The combined rise in surface temperature and humidity, amplification of heat stress is expected across india, particularly over the Indo-Gangetic and indus river basins, the report notes.
