Global warming to kill off insects

Say goodbye to your ant farm - climate change may prove to be a more powerful pesticide than DDT. New research shows that even relatively minor fluctuations in temperature could have devastating effects on insects, especially in the world's tropical regions.

An article in the Independent quotes Curtis Deutsch, a professor from UCLA who co-authored the study to be published in the Proceedings of the National Academy of Sciences, as saying that although temperatures are not expected to increase as much in the tropics as at the poles, even a 1C or 2C jump could be fatal for insects already surviving at their edge of their climactic comfort zone.

While that doesn't look like it's all downside, especially for anyone who's been up north during blackfly season, the repercussions could be pretty ugly. Insects in warm climates are key to a healthy environment, pollinating flowers and plants, carrying away organic waste (read: eating crap) and serving as dinner for various birds and animals. If the bugs fail to adapt to a changing climate, the consequences will be felt all the way up the food chain.
