"The complete melt of the Greenland ice sheet could occur at lower global temperatures than previously thought, a study in the journal Nature Climate Change showed on Sunday, increasing the threat and severity of a rise in sea level."

"Fearing that climate change could wipe out their entire Pacific archipelago, the leaders of Kiribati are considering an unusual backup plan: moving the populace to Fiji."

"General Motors, a company that's made strides to lower the carbon footprint of driving, is taking heat from 10,000 of its customers for a donation its charitable foundation made to an institute that casts doubt on climate science."

"From its perch in a spacious brand-new headquarters blocks from the White House, the Cato Institute has built on its reputation as a venerable libertarian research center unafraid to cross party lines. Now, however, a rift with one of its founding members — the billionaire conservative Charles Koch — is threatening the institute's identity and independence, its leaders say, and is exposing fault lines over Mr. Koch's aggressive and well-financed brand of Republican politics."

Ice -- on both sea and land, near the poles and at high altitudes -- is connected in a number of ways with changing climate, as both a symptom and a cause. Several news stories about ice melt have come out recently. Charlie Petit at MIT's Knight Science Journalism Tracker has done a bang-up job of summarizing them. So we will save time and effort by linking directly to his work, which will richly reward the climate-curious.

"When at least 80 tornadoes rampaged across the United States, from the Midwest to the Gulf of Mexico, last Friday, it was more than is typically observed during the entire month of March, tracking firm AccuWeather.com reported on Monday. According to some climate scientists, such earlier-than-normal outbreaks of tornadoes, which typically peak in the spring, will become the norm as the planet warms."

"RICHMOND -- After two years and more than half a million dollars in legal fees, the Virginia Supreme Court on Friday rejected Attorney General Ken Cuccinelli II's assertion that the state's flagship university had to turn over documents related to global warming. The decision was a defeat for Cuccinelli (R), a global-warming skeptic who has garnered national attention for a string of high-profile lawsuits, just as he kicks off his campaign for governor next year. ..."

"The world's oceans are turning acidic at what could be the fastest pace of any time in the past 300 million years, even more rapidly than during a monster emission of planet-warming carbon 56 million years ago, scientists said on Thursday.

Looking back at this bygone warm period in Earth's history could offer help in forecasting the impact of human-spurred climate change, researchers said.
