Is it the albedo effect? Is it increased ice dynamics? Dutch researchers add a third player to better understand why Arctic melting is happening as fast as it is. The clue is in the winter polar night skies, they say.
Yes, indeed, we’re a couple of days late bringing you the news. But this could be an important update to our Arctic melting coverage. It’s feedback-driven (after all), American and French researchers say.
Today is September 14 2011, the day the Climate Reality Project makes a stand against the ‘new normal of climate denial.’ Over 24 times zones there will be 24 climate presentations in which public attention will be focused on the … Continue reading
It´s September and we have about two weeks to go till the annual Arctic sea ice minimum. As far as we can tell it´s going to be a close call – with a good chance that this year will beat … Continue reading
Here’s another climate model study that challenges the Arctic tipping point idea. Arctic melting is still sensitive to temperature rise though and any further increase in atmospheric CO2 will keep translating to further ice loss. According to the new NASA … Continue reading
Computer simulations of the US National Center for Atmospheric Research indicate that the natural Arctic climate variability, like seasonal and annual variations in pressure systems, wind patterns and precipitation or cloud cover, could be larger than previously thought.
As Edward Lorentz once put it so eloquently in his Chaos Theory is that something as small as the flutter of a butterfly’s wing can ultimately cause a typhoon halfway around the world. Then what influence could something as large … Continue reading
During the Holocene Climatic Optimum of 8,000 to 5,000 years ago, the Arctic sea ice was less than 50% [so <2.6 mln sq km] of the lowest extent on satellite record, the 2007 melting record, researchers of Copenhagen University stated … Continue reading
