The Caribou and us.
Sometimes the most important news is what is not happening.
That comment in a recent article along with the following adaptation (from the French) of a story sent to me by a colleague in Quebec Canada made me reflect on why the global community is not focused and active on pushing for immediate reductions in greenhouse [...]

Massive ice island breaks off Greenland
August 7th — A piece of ice four times the size of Manhattan island has broken away from an ice shelf in Greenland, according to scientists in the U.S.
The 260 square-kilometer (100 square miles) ice island separated from the Petermann Glacier in northern Greenland early on Thursday, researchers based at the University of Delaware said.
The [...]

The permafrost methane problem.
In 2008 when I wrote ZERO Greenhouse Emissions, I included a chapter ‘Mother Natures Super Salesman’ to attempt to get the point across that unless we decarbonise our activities in the short term Mother Nature would kick in some of her stores of carbon and methane. Many other facts were revealed and I would encourage [...]

Arctic Climate May Be More Sensitive to Warming Than Thought, Says New Study
A new study shows the Arctic climate system may be more sensitive to greenhouse warming than previously thought, and that current levels of Earth’s atmospheric carbon dioxide may be high enough to bring about significant, irreversible shifts in Arctic ecosystems.
Led by the University of Colorado at Boulder, the international study indicated that while the mean [...]

Sea Ice in the Arctic Not Recovering: Another Critical Minimum Forecast
A critical minimum for Arctic sea ice can again be expected for late summer 2010, according to researchers.
Scientists from the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association (AWI) in Bremerhaven and from KlimaCampus of the University of Hamburg have now published data in this context in the annual issue of [...]

Melting ice makes the Arctic a vicious circle
EVERYONE knows how much hotter it feels to wear a black T-shirt, rather than a white one, on a warm day.
In the same way, the melting of sea ice in the Arctic, revealing the dark water below, has been shown by Australian scientists to be the main cause of unusually rapid warming at the top [...]

Scientists find signs of global warming in Arctic Ocean
St. Petersburg, April 21 (IANS/RIA Novosti) Increasing amount of Organic materials dissolved in the Arctic Ocean may be an indication of global warming, scientists have said.
The amount of organic materials dissolved in the Arctic Ocean has doubled over the last 12 years, which is possibly one more sign of global warming, Russian oceanographer Natalia Lapina [...]

Copenhagen pledges set Earth for warming
Carbon-curbing pledges under the Copenhagen Accord are likely to doom Earth to warming of three degrees Celsius (5.4 degrees Fahrenheit) or more, compared to the deal’s target of 2C (3.6 F), scientists said on Wednesday.
In an analysis published by the journal Nature, researchers at the Potsdam Institute for Climate Impact Research (PIK) near Berlin said [...]

Massive Arctic Ice Cap Is Shrinking, Study Shows; Rate Accelerating Since 1985
Close to 50 years of data show the Devon Island ice cap, one of the largest ice masses in the Canadian High Arctic, is thinning and shrinking.
A paper published in the March edition of Arctic, the journal of the University of Calgary’s Arctic Institute of North America, reports that between 1961 and 1985, the ice [...]
