NASA satellites have been tracking such data for decades — everything from ocean and air temperatures and melting sea ice to forest fires and solar flares. But until now this data has not been offered in a visually compelling form that describes what the scientists are talking about.
Recognizing the need to get this amazing data out to the public, NASA hired a team of animators to create videos that composite real images of the Earth as seen from space with time-lapse, color-coded charts based on reams of scientific data. These videos are available on NASA's recently launched A Warming World website.
Many of the videos like the "Temperature Puzzle" video are available in full-screen high definition. You can search all of their animations by keyword — hours and hours of nerd entertainment! Check out a "Tour of the Cryosphere".
