A new website by NASA features videos, images, and articles about climate change. A Warming World has been designed to help all of us understand what warming means and how it impacts our world. Here's a sample:
Each year, scientists at NASA'S Goddard Institute for Space Studies analyze global temperature data. The past year, 2009, tied as the second warmest year since global instrumental temperature records began 130 years ago. Worldwide, the mean temperature was 0.57°C (1.03°F) warmer than the 1951-1980 base period. And January 2000 to December 2009 came out as the warmest decade on record.
