At this rate, CSE said, temperatures would breach the 1.5 degree Celsius mark, the benchmark under Paris climate accord to limit temperature rise, in the next two decades
Indicating the alarming impact of climate change on warming in the country, annual mean temperature has been found to have increased by 1.2 degree Celsius since 1901, a new study by Centre for Science and Environment (CSE) showed. The study also showed that the annual mean temperature rise has been especially rapid from 1995 onward, when the anomaly crossed the two degree mark and that the winter of 2017 was the warmest on record in the country.
At this rate, CSE said, temperatures would breach the 1.5 degree Celsius mark, the benchmark under Paris climate accord to limit temperature rise, in the next two decades.
The non-profit organization analysed Met department's temperature data set from 1901 onward, the year Met observations began. The period between 1901 and 1930 was selected for baseline data to analyse the anomalies in temperatures. The analysis looked at the annual and seasonal trends of mean, maximum and minimum temperatures.
A look at the details of seasonal anomalies in temperatures is even more worrying. For the winter months of January and February, there has been a steady anomaly of 1 degree Celsius from the early 1990s and from 2006 onward, it has even breached the 2 degree Celsius anomaly. For instance, in the winter of 2006, the anomaly was 2.44 degree Celsius and anomaly for the 2017 winter was 2.95 degree Celsius, making it the warmest on record.
"We are experiencing frequent extreme weather events, and our weather is becoming unpredictable. Losses due to extreme weather events are mounting and it is our poor who are suffering the pains of climate change," said Chandra Bhushan, deputy director-general, CSE.
...& ANALYSIS
- With India warming rapidly, the implications of this are serious for the economic, social and ecological well-being of the country
- The temperature anomalies also reflect through its impact on larger weather events. In 2010 when average temperature was 2.05o C higher than the baseline, large parts of India saw severe heat wave conditions
