The Climate Post: Grid, for lack of a better word, is good
First Things First: Cars, trucks, planes, and other things that go add more greenhouse gas to the atmosphere than any other sector where end-users burn their own fuel. And transportation added more energy-and-climate headlines this week than any other sector, driven by an emergency congressional payout to continue the “cash-for-clunkers” program and General Motors’ promotional […]

With a melting Greenland as a backdrop, Danish minister urges climate action
The Sermeq Kujalleq glacier (also known as the Jakobshavn Glacier) near where it flows into the sea in western Greeland. The photo was taken in the summer of 2008. Scientists have recorded the glacier’s rapid melt over the past decade.Courtesy kriskaer via Flickr Here’s a tip for the ministers who are attending the latest of […]

Greenland ice sheet could raise East Coast sea levels 20 inches by 2100 – to over 6 feet
The eastern United States must plan on the very real possibility that total sea level rise by 2100 will exceed 6 feet on our current emissions path. Sadly, the Washington Post got the story only half right. This week I’ll focus on our best understanding of the impacts that Americans face from human-caused climate change. […]

MIT doubles its 2095 warming projection to 10°F
Today’s question: How the heck does the Greenland ice sheet survive accelerated disintegration from projected 20°F warming by the 2090s? I previously blogged on how the Massachusetts Institute of Technology Joint Program on the Science and Policy of Climate Change has joined the climate realists — the growing group of scientists who understand that the […]

Sea levels to surge at least a metre by 2100, scientists warn at Copenhagen meeting
COPENHAGEN — Months before make-or-break climate negotiations, a conclave of scientists warned Tuesday that the impact of global warming was accelerating beyond a forecast made by U.N. experts two years ago. Sea levels this century may rise several times higher than predictions made in 2007 that form the scientific foundation for policymakers today, the meeting […]

Scientists find bigger than expected polar ice melt
GENEVA — Icecaps around the North and South Poles are melting faster and in a more widespread manner than expected, raising sea levels and fuelling climate change, a major scientific survey showed Wednesday. The International Polar Year survey found that warming in the Antarctic is “much more widespread than was thought,” while Arctic sea ice […]

Massive Greenland meltdown? Not so fast, say scientists
The recent acceleration of glacier melt-off in Greenland, which some scientists fear could dramatically raise sea levels, may only be a temporary phenomenon, according to a study published Sunday. Researchers in Britain and the United States devised computer models to test three scenarios that could account for rapid — by the standards applied to glaciers […]

Two trillion tons of land ice lost since 2003, rate of Greenland summer ice-loss triples 2007 record
The AP reports on new data to be presented at the annual meeting of the American Geophysical Union: More than 2 trillion tons of land ice in Greenland, Antarctica and Alaska have melted since 2003, according to new NASA satellite data that show the latest signs of what scientists say is global warming. More than […]

Greenland ice-loss soars: Bad for you, great for bottled water biz
A new study in Geophysical Research Letters ($ub. req’d) led by the Jet Propulsion Laboratory finds … … the ice sheet was losing 110 ± 70 Gt/yr [billion tons/year] in the 1960s, 30 ± 50 Gt/yr or near balance in the 1970s-1980s, and 97 ± 47 Gt/yr in 1996 increasing rapidly to 267 ± 38 […]
