Global Warming: Fast Facts Fast

A good link to some fast "facts on global warming" from the National Geographic.

Global Warming Fast Facts

As a taster here are facts 1 and 2.
There is little doubt that the planet is warming. Over the last century the average temperature has climbed about 1 degree Fahrenheit (0.6 of a degree Celsius) around the world.

The spring ice thaw in the Northern Hemisphere occurs 9 days earlier than it did 150 years ago, and the fall freeze now typically starts 10 days later.

The 1990s was the warmest decade since the mid-1800s, when record-keeping started. The hottest years recorded: 1998, 2002, 2003, 2001, and 1997.

• The multinational Arctic Climate Impact Assessment (ACIA) report recently concluded that in Alaska, western Canada, and eastern Russia, average temperatures have increased as much as 4 to 7 degrees Fahrenheit (3 to 4 degrees Celsius) in the past 50 years. The rise is nearly twice the global average. In Barrow, Alaska (the U.S.'s northernmost city) average temperatures are up over 4 degrees Fahrenheit (2.5 to 3 degrees Celsius) in 30 years.

The United Nations' Intergovernmental Panel on Climate Change (IPCC) projects that global temperatures will rise an additional 3 to10 degrees Fahrenheit (1.6 to 5.5 degrees Celsius) by century's end.

Thanks to Eco-critic for the hat-tip. Eco-critic begin:

"This blog aims to discuss the political issues associated with global warming and climate change. It seeks to address the problem from a non-ideological perspective, from neither left or right, but from the viewpoint that this issue transcends our petty political divides. Over time the author hopes to expand the scope of the blog to deal with the emergence of eco-critical issues in the humanities."
