Last summer a headline from the Christian Science Monitor read: "Arctic Sea Ice Melting Faster Than Expected". The first line of the article sounded the environmental alarm.
It said: "Arctic Ocean sea ice, one of the most visible indicators for global warming, may be headed for another recordbreaking summer decline." There were similar articles concerning a connection between global warming and melting Arctic sea ice in many other magazines and newspapers at the time.
However, when conditions in the Arctic change, there is no longer any apparent media interest in reporting about Arctic sea ice. So, everyone concerned with global climate change should ask this question; If Arctic Sea ice really is "one of the the most visable indicators for global warming", why is the mainstream media not reporting what is happening in the Arctic Sea today?
The fact is that after last summer's Arctic ice melt fell short of the 2007 record extent, Arctic sea ice has been increasing at the fastest rate seen in years. As of last Friday, it was running ahead of the same day in October of last year by 31.3%. (See: annual comparison in purple shade in picture above - 10/17/2007 5,663,125 square kilometers, 10/17/2008 7,436,406 square kilometers ).
The truth is that despite all the recent media hype, melting Arctic Sea Ice probably has nothing to do with man-made global warming. (See: Melting Arctic Sea Ice And Global Warming Hype) on eWorldvu.com .
In fact, there are several other possible explanations for the recent record melt in Arctic sea ice that have little to with global warming.
A scientist at the University of Fairbanks, Alaska, (Igor Polyakov) points out that pulses of unusually warm water have been entering the Arctic Ocean from the Atlantic, which several years later are seen in the ocean north of Siberia. These pulses of water are helping to heat the upper Arctic Ocean, contributing to summer ice melt and helping to reduce winter ice growth.
Another scientist, Koji Shimada of the Japan Agency for Marine Earth Science and Technology, reports evidence of changes in ocean circulation in the Pacific side of the Arctic Ocean.
"Through a complex interaction with declining sea ice, warm water entering the Arctic Ocean through Bering Strait in summer is being shunted from the Alaskan coast into the Arctic Ocean, where it fosters further ice loss. Many questions still remain to be answered, but these changes in ocean circulation may be important keys for understanding the observed loss of Arctic sea ice.”
The media reports that the recent record Arctic ice melt is connected with global warming as fact, when it certainly is not. After all the environmental hype concerning record melting Arctic sea ice last summer, there is a notable lack of reporting on the dramatic annual increase (31%) in the extent of Arctic Ice in evidence in the past week.
Indeed, after a summer of Arctic ice melt from global warming media hype, the rapid increase in Arctic Ice this year is a media story that we just don't hear.
