Video of Decline of Arctic Sea Ice


No matter which side of the fence you are on global warming, there is no doubt that the earth's temperature has been rising in recent times.

The debate will continue on how much man has influenced this, but the evidence of the warming itself is irrefutable.

Check out  this HD Animation from NASA of Arctic Sea Ice Decline (note, my browser plays it slowly and erratically, so you might need the latest Quick Time updates).

Arctic Sea Ice key points

  • This NASA animation shows the annual Arctic sea ice minimum area from 1979 to 2012 with a graph overlay.
  • Satellite data show that Arctic sea ice has been declining both in extent and thickness.
  • Since 1979, September Arctic sea ice extent has declined by 13 percent per decade.
  • Sea ice covering the Arctic Ocean declined to the lowest extent on record in 2012.

So, is this a natural cycle, human influence, or a combination of the two?

Right or wrong, the American Meteorological Society's official statement on climate change is very stern.  In the "Final Remarks"it says "The dominant cause of this warming since the 1950s is human activity".
