India’s first ever climate change assessment

Date: 20 June 2020 Tags: Climate Change

Issue

For the first time, India has released its own national report on the state of the climate crisis.

 

Background

The report, Assessment of Climate Change over the Indian Region, takes a close look at where we stand regarding long-term changes in climate patterns, and their attendant risks.

 

Details

  • The report goes on to warn that the rapid changes in India’s climate will place increasing stress on the country’s natural ecosystems, agricultural output, and fresh water resources, while also causing escalating damage to infrastructure and economy.

  • The big revelation is that India’s average temperature has increased by 0.7 degrees Celsius between 1901-2018, and that this is purely due to the emission of greenhouse gases (GHG).

  • The report further states that in a best-case scenario of immediate mitigation of emissions, India’s temperature will still rise by 2.7 degrees Celsius by 2099. The worst-case scenario sees a rise of 4.4 degrees Celsius by the end of the century.

  • It has been learnt that the sea level near Mumbai is rising at the rate of 3cm per decade. Off the Bengal coast, it’s 5cm per decade.

  • Surface temperatures in the Indian Ocean (including the Bay of Bengal and the Arabian Sea) have risen by 1 degree Celsius between 1951-2015, higher than the global average.

  • When it comes to the monsoon, the report establishes that precipitation over north India has decreased by 6% (1951-2015) due to the polluting aerosol “brown cloud".

  • The monsoon is expected to become more extreme over the coming decades, with longer dry spells alternating with very heavy rain. 

  • The report points out that April-June heat waves will become four times more frequent by 2099 (compared to 1976-2005), and their duration might also double.
