On World Environment Day, Centre for Science and Environment (CSE) is re-emphasising the crisis that we are faced with today – by releasing the results of a study it has done to find out how India has warmed over the years. The analysis looks at temperature trends in the country – both annual and seasonal – from 1901 till recent years. And it finds that the country has been getting warmer continuously, consistently and rapidly.
CSE researchers have plotted this rise in temperature on an animated spiral – the first such visual representation to come from India. A similar climate spiral graph depicting global rise in temperatures is already in existence.
What the analysis says
- 2016 was the second warmest year on record.
- 13 out of the 15 warmest years were during the past 15 years (2002-2016). The last decade (2001-2010/ 2007-2016) was also the warmest on record.
- Annual mean temperature in India has increased by about 1.2oC since the beginning of the 20th century.
- Annual mean temperature in India has rapidly increased since 1995. At this rate of increase, it will breach the 1.5oC mark within the next two decades. 1.5oC is the aspirational target set under the Paris Agreement.
- In three out of four seasons (or nine months in a year), temperature in India has already increased by more than 1.5oC since the beginning of the 20th
- Winters and pre- monsoon (summers) and post-monsoon seasons have seen rapidly increasing warming.
- Mean temperature during winter months is now over 2oC warmer than in the beginning of the 20th century.
- In the winter of 2016-17, the mean temperature was 2.95oC higher than the 1901-1930 baseline – the warmest in recorded history.
- It is only during the monsoon months that the temperature increase is about 1o
