India will not accept limits on its greenhouse gas emissions at climate talks later this year and instead will focus on economic growth and lifting its people out of poverty, according to Environment Minister Jairam Ramesh. He said that a legally binding emissions target would endanger India’s food security and transport, adding, “India cannot and will not take emission reduction targets because poverty eradication and social and economic development are first and overriding priorities.”

The explosive growth of modern refrigerants, originally developed to replace ozone-destroying chemicals, could become a significant cause of global warming if they are not soon replaced by a new class of coolants, according to Dutch and U.S. researchers.

Reporting in the Proceedings of the National Academy of Sciences, the scientists said that hydrofluorocarbons (HFCs) – now used in most air conditioning in cars and buildings – are a potent greenhouse gas whose heat-trapping effects currently equal less than one percent of all CO2 emissions worldwide. But booming economic growth in the developing world and the rapid spread of air conditioning mean that by 2050 HFCs could cause at least 25 percent of human-induced global warming, the study said.
