NASA animation shows climate change impact


NASA, Jet Propulsion Laboratory, and the California Institute of Technology have come up with an online animation called the Climate Time Machine offering a highly effective visual demonstration of the impact of climate change.

The Climate Time Machine shows the progress in 4 aspects of global warming - Ice Melt, Sea Level, CO2 Emissions, and Average Global Temperature - over differing periods of time. The data used aren't projections or predictions, but actual recorded numbers which in some cases date back more than a century.

Particularly striking is the map which highlights global temperature since 1885. Temperatures remain relatively benign until the 1970's but the map starts changing colour dramatically in the 1990's, and by 2007 a good chunk of the planet is bathed in a flaming orange, indicating rapid and dramatic warming. Highly recommended for climate change skeptics.
