Greenhouse Neutral Foundation comment – I have long admired James Hansen as a person who cares for the future of all that we share our fragile planet with. The answers to all of the significant challenges we face in the imminent future is in OUR hands.
We need to accept this moral responsibility. The following article [...]

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 [...]

From John Cook Sceptical Science
I’m talking at the University of Queensland next week so I thought I might use Skeptical Science to test-drive a new visual metaphor. Sometimes in the climate debate, we get a bit lost in the data and statistical analysis, forgetting the sheer scale of the impact we’re having on our climate. [...]

New sediment cores from an Antarctic research drilling program suggest that the southernmost continent has had a more dynamic history than previously suspected
ERICE, Italy—If you think of Earth’s poles as fraternal twins, the Arctic has been the wild one in recent years, while the Antarctic has been a steady plodder. Withered by summer heat, Arctic [...]

In another display of the sea change that has occurred at the US Environmental Protection Agency under the current administration, a new report was issued yesterday regarding indicators of climate change. The report, entitled “Climate Change Indicators in the United States,” measures 24 separate indicators showing how climate change affects the health and environment of [...]

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 [...]

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 [...]

After little net change in the 1990s, Greenland is now melting and shedding billions of tons of ice, according to NASA satellite observations. This trend especially concerns scientists because meltwater and ice emptying into the ocean raise global sea level. Currently, sea level is increasing at about 1.25 inches per decade, and researchers estimate Greenland [...]

Study: Northwest areas thinning since 2005
Melt along the southern edge of Greenland’s ice sheet is now moving up its northwest coast, a new study shows.
“The ice mass loss has been very dramatic” since 2005, John Wahr, study co-author and a University of Colorado at Boulder physics professor, said in a statement.
The team, led by Denmark’s [...]

From the News desk at the BBC – A review from the UK Met Office says it is becoming clearer that human activities are causing climate change.
It says the evidence is stronger now than when the Intergovernmental Panel on Climate Change carried out its last assessment in 2007.
The analysis, published in the Wiley Interdisciplinary Reviews [...]
