NASA: Arctic sea ice reaches second-lowest level on record

A new preliminary report from NASA confirms our worries. The sea ice at the Arctic is disappearing.

NASA reports that the Arctic sea ice has reached a second all-time low "since the dawn of the satellite era". Previous record low for September was in 2005. NASA says that this year' loss of sea ice "further reinforces the strong negative trend in summer sea ice extent observed during the past 30 years". In the past sea ice has covered about 60% of the Arctic. But this winter the sea ice covered less than 30%.

"In March, when the Arctic reached its annual maximum sea ice coverage during the winter, scientists from NASA and the data center reported that thick, older sea ice was continuing to decline. According to NASA-processed satellite microwave data, this perennial ice used to cover 50-60 percent of the Arctic, but this winter it covered less than 30 percent. Perennial sea ice is the long-lived layer of ice that remains even when the surrounding short-lived seasonal sea ice melts to its minimum extent during the summer."

The image shows that the daily Arctic sea ice extent for September 12, 2008, was 4.52 million square kilometers (1.74 million square miles). The orange line shows the 1979 to 2000 average extent for that day. The black cross indicates the geographic North Pole. A high-resolution image can be found here.

Mother earth has been put through abuse of using resources and polluted. The different changes on earth, could possibly be the earth cleansing itself from all the years destruction. As the living way of humans change, the earth must change as well.
