Major Arctic sea ice melt is expected this summer
May 2, 2008 By RANDOLPH E. SCHMID, AP Science Writer(AP) -- The Arctic will remain on thinning ice, and climate warming is expected to begin affecting the Antarctic also, scientists said Friday. "The long-term prognosis is not very optimistic," atmospheric scientist Jennifer Francis of Rutgers University said at a briefing.

"NASA satellites found that last winter's Arctic Sea ice covered 2 million square kilometers (772,000 square miles) more than the last three years' average. It also was 10 to 20 centimeters (about 4-8 inches) thicker than in 2007. The ice between Canada and southwest Greenland also spread dramatically. "We have to go back 15 years to find ice expansion so far south," Denmark's Meteorological Institute stated."

Ithink it is the steady reduction in summer sea ice that is the best predictor of global warming.

No,the best INDICATION of global warming is TEMPERATURE.Official data now shows that the temperature has hardly changed over the past 10 years and fallen in last year.Even some of the British press "believers" have published it ,along with an "official" prediction that temps will not rise,or,even fall further in the next decade or so.
The change in SEA ice has been put down,mainly,to changes in currents.This would also explain some coastal melting and increase inland,of the ice cap.

niftyswell - If you are content with your understanding of the world being only influenced by newswire service headlines then you will forever by blown about by the whims of editors. Your assignment - learn the difference between weather and climate.
mikiwud - you simply do not want to accept that short term variabilities are different than long term changes.
Notparker - why do call "nonsense" for this article, which is simply a report on observations?
All of the above - what you continue to ignore is that "energy" is not "temperature", and changes on Earth follow the law of conservation of energy. There is no such thing as "conservation of temperature." Frankly, all three of you apparently were not paying attention in high school chemistry and physics classes.

Also, don't want to insult anyone, but this illustrates why engineers and scientists see things differently. An engineer responsible for, say, a faulty bridge must have calculated something incorrectly. A scientist with a faulty model must have made an incorrect an incorrect assumption, or not had fine enough resolution, or one of dozens of other problems that might come up while doing science - and they need to try and correct this and experiment some more. That's how science works. To say they should be held accountable is an engineering mindset, and doesn't make sense with science.
