Global Temperatures 8th Warmest on Record

According to the National Oceanic and Atmospheric Administrationโ€™s latest analysis of global temperatures, October 2011 was the 8th warmest October ever recorded since 1880. NOAAโ€™s National Climatic Data Centre provide a series of reports as part of their services to the government, business and community leaders, which have been helping everybody keep a track of […]

Satellite Imagery of Arctic Sea Ice Second Lowest Extent (VIDEOS)

On September 9 scientists from NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado in Boulder showed satellite data that capped summertime sea ice coverage at the second lowest ever recorded since records were first kept. Seen below marked out in yellow is the 30 year average, while the red line represents the opening of the Northwest Passage shipping lane.

Arctic Sea Ice Minimum Extent Imagery and Video

As reported yesterday the University of Colorado at Boulder’s National Snow and Ice Data Center announced that the Arctic sea ice minimum extent would come in as second lowest since recording began back in 1979. Now, NASA’s Goddard Space Flight Center has provided their own series of images and videos to back up that report, showing the extent of Arctic sea ice for September 9, 2011.

No Tipping Points for Arctic Sea Ice Loss

A growing body of scientific evidence has led researchers to believe that in a warmer climate there will be no โ€œtipping pointโ€ beyond which the Arctic sea ice cannot recover if temperatures start to decrease. Added to this is new research out of the University of Washington which suggests that even if the planet warmed enough to melt all polar sea ice, it could still recover if the temperatures cooled again.

The Arctic Sea Ice

“Lots of people think of the Arctic as just a flat expanse of white. This couldnโ€™t be further from the truth. There are all sorts of cracks (leads) and mountains (ridges), similar to tectonic plates. The ice below is constantly moving via the winds and currents, and those forces acting on each piece of ice makes for a very dramatic seascape”
