Parts of China, India and the eastern US could all become too warm in summer for people to lose heat by sweating, expert warns
by David Adam in Copenhagen 
Severe global warming could make half the world’s inhabited areas literally too hot to live in, a US scientist warned today. Parts of China, India and the eastern US could all become too warm in summer for people to lose heat by sweating – rendering such areas effectively uninhabitable. Steven Sherwood, a climate expert at Yale University, told a global warming conference in Copenhagen that people will not be able to adapt to a much warmer climate as well as previously thought. The physiological limits of the human body will begin to render places impossible to support human life if the average global temperature rises by 7C on pre-industrial levels, he said. "There will be some places on Earth where it would simply be impossible to lose heat," Sherwood said. "This is quite imaginable if we continue burning fossil fuels. I don’t see any reason why we wouldn’t end up there." …
