“India will be one of the states hardest hit by climate change, with increased coastal flooding and melting Himalayan glaciers. Rising global temperatures would make water security an even greater problem in India-Pakistan relations. William Cline, a senior fellow at the Peterson Institute for International Economics, has estimated that a modest increase in average global temperatures would cut agricultural output in India by 38 percent.
The stakes are as great for China. Earlier this year, the head of China’s national weather service warned that climate change would have “huge impacts” on the country, including reduced crop yields, ecological harm and unstable river flows. A 2011 government report anticipated a 5-to-20 percent drop in grain output resulting from climate change by 2050. Never mind the crisis the Chinese leadership already faces from unsustainable levels of air pollution in the country’s major cities.”
