Effects of Climate Change are not Contained within Nations – The Impact on India: Nagraj Adve

Guest post by NAGRAJ ADVE

This post is the second part, excerpted and slightly adapted, from the booklet by Nagraj Adve, Global Warming in the Indian Context: An Introductory Overview (Ecologise Hyderabad 2019). The first part appeared in Kafila on 1 July 2019

While the earlier post covered the basic science of global warming, the roots of the problem, and how inequality relates to climate change, this part focuses on key impacts of climate change in India, on humans and other species, and the reasons for urgency in tackling the problem.

Before we consider impacts in India and elsewhere, a few things are useful to keep in mind:

– Unlike most other forms of pollution, the source of carbon dioxide and where its effects are felt can be very far apart. Carbon dioxide generated in the United States affects people on the Orissa coast.

– A significant portion of carbon dioxide emitted today will remain in the atmosphere for centuries, influencing future climates.

– Even after the world ceases to emit carbon, higher average temperatures are “largely irreversible for a thousand years” because the gains of lesser radiation being trapped gets offset by the reduced loss of heat to the oceans. Hence, climate change is the new ‘normal’.

– Impacts will worsen because of the time lag between emissions and warming. Some of it is unavoidable. Our urgent intervention is needed to make sure they do not get much worse, and that the situation does not spiral out of our control.
