For the latest, most up-to-date information on climate change, the National Science Foundation (NSF) offers a new website. "Our planet's climate affects - and is affected by - the sky, land, ice, sea, life, and people found on it. To understand the entire story of climate change," according to the site, "we must study all of the natural and human systems that contribute to and interact with Earth's climate system."  Visit: http://www.nsf.gov/news/special_reports/climate/
