“By the end of the twenty-first century, average temperature over India is projected to rise by approximately 4.4 degrees Celsius,” the report says.
New Delhi| According to a government report on the impact of climate change on the country, the average temperature over India is projected to rise by 4.4 degrees Celsius, while the intensity of heatwaves is likely to increase by 3-4 times by the end of the century.
During 1901-2018, India’s temperature has risen by 0.7 Degree Celsius, largely owing to the Green House Gases-induced warming, states the report by the Ministry of Earth Sciences.
Science and Technology Minister Harsh Vardhan is likely to publish the report on Tuesday.
Centre for Climate Change Research, a cell under MoES” Indian Institute of Tropical Meteorology, Pune, has prepared this report.
“By the end of the twenty-first century, average temperature over India is projected to rise by approximately 4.4 degrees Celsius,” the report says.
The temperatures of the warmest day and the coldest night of the year have risen by about 0.63 degrees Celsius and 0.4 degrees Celsius respectively in the 30-year period between 1986 and 2015.
According to this report, 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.
The report also suggests that the frequency of occurrence of warm days and warm nights is projected to increase by 55 percent and 70 percent.
“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 added.
It is also projected that the average duration of heatwave events will also double. According to the report, particularly over the Indo-Gangetic and Indus river basins, the combined rise in surface temperature and humidity, and amplification of heat stress is expected across India.
As per the reports, Sea Surface Temperature (SST) of the tropical Indian Ocean has risen by a degree Celsius on average during 1951-2015, comparatively higher than the global average SST warming of 0.7 degree Celsius over the same period.
