Greenland on the rocks, renewable energy gets stiffed again
The melting of Greenland could send cities like New Orleans under the sea. The $26 billion teacher-saving bill is bad news clean energy.

Ten green stories you probably missed this week
The big story of the week, of course, is that BP, after almost three miserable months, may have finally stopped its Gulf gusher. (Emphasis on “may.”) But chances are you missed these greener tales — from the beauty of pond scum to the bendable bike to the regenerative power of beer. Flasks of algae waiting […]

Paleoclimatologist studies sea levels in a desert
Exactly how much did the sea level rise three million years ago? Okay. Probably not a question you’ve asked yourself lately. But the question and, more importantly, its answer are significant. They will help scientists understand how fast and how high our current sea levels are likely to rise as today’s global warming trend melts […]

The Climate Post: BP oil spill washes up on Potomac shores
First things first: Oil-spill updates continue to gush out of the Gulf and Washington at volumes difficult to estimate. BP initiated its risky “top kill” maneuver Wednesday and the Coast Guard reported cautiously this morning that the oil stream has abated. If the effort works, BP will begin to plug the well with concrete in […]

Weighing Greenland
Scott Luthcke weighs Greenland — every 10 days. And the island has been losing weight, an average of 183 gigatons (or 200 cubic kilometers) — in ice — annually during the past six years. That’s one third the volume of water in Lake Erie every year. Greenland’s shrinking ice sheet offers some of the most […]

The future of freezing
Cross-posted from Climate Central. In many parts of the U.S. March went out like a lion this year. But a new interactive map of high-resolution climate projections from Climate Central promises much tamer, warmer Marches in the future. In fact, freezing March temperatures will retreat northward this century like a routed army. (The retreat would […]

Nature: “Dynamic thinning of Greenland and Antarctic ice-sheet"
The most detailed satellite information available shows that ice sheets in Greenland and western Antarctica are shrinking faster than scientists thought and in some places are already in runaway melt mode, a new study found…. Using 50 million laser readings from a NASA satellite, scientists for the first time calculated changes in the height of […]

The Climate Post: Climate change blamed for New York midtown traffic
First Things First: The journal Nature has published a study that attempts to find numerical “planetary boundaries” for global change, an effort that the authors believe will help policymakers better understand humanity’s impact on the planet and its life. A team of Earth scientists, led by the Stockholm Resilience Center, has identified and defined nine […]
