Extreme weather events on rise in India

New Delhi : Average temperature of India experienced a rise of 0.7 degree Celsius, along with decline in rainfall, significant increase in frequency of very severe cyclonic storms and droughts in over a decade due to human activities, the Ministry of Earth Sciences in its research report said.

The contentions were made in a report issued by the ministry on the impact of climate change. It will be published by Union Minister Harsh Vardhan on June 19.

According to the report, "Since the middle of the twentieth century, India witnessed rise in temperature; decrease in monsoon; rise in extreme temperature and rainfall, droughts, and sea levels; and increase intensity of severe cyclones.

The report, prepared by researchers of the Centre for Climate Change Research, a cell under The Ministry's Indian Institute of Tropical Meteorology, Pune, further stated that there is compelling scientific evidence that human activities have influenced these changes in regional climate.

India's average temperature has risen by around 0.7 degrees Celsius during 1901-2018, it said, adding that the rise is largely on account of GHG-induced warming and partially offset by forcing due to anthropogenic aerosols.

It states that the average temperature over India is projected to rise by 4.4 degrees Celsius, while the intensity of heat waves is likely to increase by 3-4 times by the end of the century.

In the 30-year period between 1986 and 2015, temperatures of the warmest day and the coldest night of the year have risen by bout 0.63 degrees Celsius and 0.4 degree Celsius.

According to the report, 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.

Alarmingly, sea surface temperature of the tropical Indian Ocean has also risen by one degrees Celsius on average during 1951-2015.

"The frequency of very severe cyclonic storms during the post-monsoon season has increased significantly (+1 event per decade) during the last two decades (2000-2018)," it added.

This came in the backdrop of Cyclone 'Amphan' and 'Nisarga' which made landfalls on May 20 and June 3 and killed several people, flattened villages, and destroyed farms.
