STUDY: SHIFTING HEAT LAYERS ABOVE ARCTIC TO BLAME FOR ICE CRISIS

Posted in New Scientific Data, News Brief on January 4th, 2008

THE DRAMATIC LOSS OF THE ARCTIC ICE CAP MAY HAVE BEEN TRIGGERED BY DISRUPTION TO THE THERMAL LAYERS OF ATMOSPHERE STACKED OVER EARTH’S FAR NORTH

It is the belief of the Stockholm University scientists involved in the study that “a possibly bigger cause for Arctic warming could be changes in heat transport in the middle of the troposphere, an atmospheric band that extends 10 kilometers (seven miles) above Earth’s surface”.

In the year just ended, summer sea ice in the Arctic shrank to about four million square kilometers (2.4 million square miles). This represents a 23% decrease from the previous record low of 5.3 million square kilometers in 2005.
