More Background

I love the How Stuff Works website, the writers concisely and intelligently explain the background to issues you're interested in and provide video and resources for your further education.

Check out their page on climate refugees: http://www.howstuffworks.com/climate-refugee.htm

And while no legislation exists in UN law, that does not mean that agencies like the UNEP and UNDP are not concerned and aware of climate refugees and the global need to prevent further forced migrations of people due to the effects of climate change. The UNEP predicted that there would be 50 million climate refugees by 2010 in 2005. This is the UNEP's map of areas most effected by climate change and those regions that will produce climate refugees over the next decade.
