Arctic temperatures the warmest in 2,000 years; 2009 Arctic sea ice loss 3rd highest (Junk science)
Weather Underground ^ | 9/4/2009 | Dr. Jeff Masters

It's time to take a bit of a break from coverage of the Atlantic hurricane season of 2009, and report on some important climate news. The past decade was the warmest decade in the Arctic for the past 2,000 years, according to a study called "Recent Warming Reverses Long-Term Arctic Cooling" published today in the journal Science. Furthermore, four of the five warmest decades in the past 2,000 years occurred between 1950 - 2000, despite the fact that summertime solar radiation in the Arctic has been steadily declining for the past 2,000 years. Previous efforts to reconstruct past climate in the Arctic extended back only 400 years, so the new study--which used lake sediments, glacier ice cores, and tree rings to look at past climate back to the time of Christ, decade by decade-- is a major new milestone in our understanding of the Arctic climate. The researchers found that Arctic temperatures steadily declined between 1 A.D. and 1900 A.D., as would be expected due to a 26,000-year cycle in Earth's orbit that brought less summer sunshine to the North Pole. Earth is now about 620,000 miles (1 million km) farther from the Sun in the Arctic summer than it was 2000 years ago. However, temperatures in the Arctic began to rise around the year 1900, and are now 1.4°C (2.5°F) warmer than they should be, based on the amount of sunlight that is currently falling in the Arctic in summer. "If it hadn't been for the increase in human-produced greenhouse gases, summer temperatures in the Arctic should have cooled gradually over the last century," Bette Otto-Bliesner, a co-author from the National Center for Atmospheric Research, said in a statement.

I have a theory on the Arctic ice cap melting....no doubt that warming temperatures could melt the ice cap...but if we remove the temperature factor, we have the accumulation of dust, volcanic ash, and desert sand on the ice surface, this covering adsorbs the suns radiation, and accelerates the melting process...

It can be demonstrated that global winds rise over the Ecuador, and descend over the Arctic regions, hence the global winds are a transport for fine dust particles, that are deposited on the Arctic ice.... Concurrent with the upper wind circulation, are the changes in surface winds, caused by such events as the occurrence of mountain ranges, expansion of deserts, and other physical changes to the earth surface...The surface winds will be deflected by such changes and direct warmer air to the Arctic ice cap...

I have been using Wunderground for years. I think it’s the best weather site. It’s only been recently they went over the dark side on GW. I may have to rethink the ten bucks a year.

Why won’t they release their raw data? Because they know it was faulty. It is also contradicted by a Danish study.

And here in northern Wisconsin and Minnesota we’ve had the coolest summer for many years - the fewest 90-degree days in many years.

"90-degree days"? You lucky dog! I'm in central Wisconsin and we have had one 90-degree day. June 23 the high was 93 degrees.

And I don't want people to think that we have been hovering at just under 90 degrees all summer because we have not. It has been a cold 'summer' with high temps rarely into even the '80's. Basically, this has been the summer that wasn't.

“... used ... tree rings to look at past climate”

-—<>-—<>-—<>-—<>-—<>-—

Invalid study.

Mann and Jone’s Hockey Stick data used those, and it has been demonstrated unequivocally that tree ring data is not reliable indication of temperatures.

Where may I find the weather records for the years 09 to 2009 AD? I would like to verify the data.

I tried this but all the Roman numerals make my head ache.

There are strong indications that Marco Polo, the Chinese, and the Scandinavians sailed an ice-free Arctic Ocean in the years around 1000AD-1300AD give or take. There are maps and many other indications of exploration on the north coasts of Canada and Russia. That would make sense, since the temperatures of Earth were a couple degrees higher than the current temperatures (despite bogus studies such as this which deny the historical evidence)

---------Marco Polo, the Chinese, and the Scandinavians----------------

All apparently using internal combustion engines.

Hmm obviously it is NOT weather related

The recent warming has been because Sarah Palin is Hot.

This arctic summer had been cooler because she was writing her book in San Diego.
