Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Past Decade Warmest on Record

Posted by feww on July 29, 2010

Earth has been growing warmer since the 1950s

Past Decade Warmest on Record According to Scientists in 48 Countries: NOAA

The 2009 State of the Climate report highlights 10 key climate indicators based on scientific evidence that the world is warming.  “More than 300 scientists from 160 research groups in 48 countries contributed to the report, which confirms that the past decade was the warmest on record and that the Earth has been growing warmer over the last 50 years.” A Report said.

This is one of a very few worthwhile studies carried out by the scientific community. Alas, they only tell you the result when it’s practically too late to do much about it.

“The temperature increase of one degree Fahrenheit over the past 50 years may seem small, but it has already altered our planet,” said Deke Arndt, co-editor of the report and chief of the Climate Monitoring Branch of NOAA’s National Climatic Data Center. “Glaciers and sea ice are melting, heavy rainfall is intensifying and heat waves are more common. And, as the new report tells us, there is now evidence that over 90 percent of warming over the past 50 years has gone into our ocean.”

Critically Endangered Species: Arctic Sea Ice

Hell Hath No Fury Like Oceans Warming!

Record Arctic ice loss in August

Previously you read on this blog that the Arctic ice cover was the second-lowest on record. The National Snow and Ice Data Center has since reported that the rate of ice loss through the month of August set a new record, reinforcing conclusions that the Arctic sea ice cover is in a long-term state of decline. With more than a week left to the end of the melt season, the Arctic shrink could still hit a new record annual low in September.

See below for the stats:

  • Arctic sea ice extent on September 3, 2008 was 4.85 million square kilometers.
  • Extent decline since the beginning of August was 2.47 million square kilometers.
  • Extent is now within 370,000 square kilometers of 2007 value on the same date (about 2.08 million square kilometers below the 1979 to 2000 average).
  • The average daily ice loss rate for August 2008 was 78,000 square kilometers per day (the fastest rate of daily ice loss ever recorded for a month of August).
  • The average daily ice loss rate for August 2007 was 63,000 square kilometers per day.
  • The average daily ice loss rate for the month of August was 51,000 square kilometers per day.

It takes very little additional energy to melt what remains of a very thinned sea ice cover!
