November 22, 2007--History shows climate changes led to war (Environmental Network News)
Global warming is one of the most significant threats facing humankind, researchers warned, as they unveiled a study showing how climate changes in the past led to famine, wars and population declines. The world's growing population may be unable to adequately adapt to ecological changes brought about by the expected rise in global temperatures, scientists in China, Hong Kong, the United States and Britain wrote in the journal Proceedings of the National Academy of Sciences. "With more droughts and a rapidly growing population, it is going to get harder and harder to provide food for everyone and thus we should not be surprised to see more instances of starvation and probably more cases of hungry people clashing over scarce food and water" said Peter Brecke, associate professor in the Georgia Institute of Technology's Sam Nunn School of International Affairs.
