Arctic Ice Decline Confirms Global Warming Predictions
Posted on Sep 14, 2006
The amount of ice being formed in the Arctic winter has declined sharply in the past two years, which a NASA scientist called “the strongest evidence of global warming in the Arctic so far.”
Also, this summer was the second-hottest on record in the continental U.S. since records started being kept in 1895.
The amount of ice being formed in the Arctic winter has declined sharply in the past two years, a finding that NASA climate researchers say significantly increases their confidence that greenhouse gases created by autos and industry are warming the Arctic and the globe.
For years, scientists have reported a steady decrease in summertime Arctic ice, but they had never before found a similar reduction in the amount of ice being created during the frigid and dark Arctic winter. This lack of effect on the Arctic winter was one flaw in the scientific models of global warming, which predicted a steady decrease in ice formation.
But a new paper by Josefino Comiso, a senior research scientist at NASA’s Goddard Space Flight Center in Greenbelt, found precisely the reduction in wintertime ice over the past two years that the model had predicted. The past two winters each produced 6 percent less ice than the average amount measured for almost three decades.
