Ocean warming threatens stability of Antarctic ice shelves

Discover: The Getz Ice Shelf extends several miles into the ocean along the western Antarctic coast. The vertical face of the ice shelf is almost 200 feet high and is estimated to extend another 1,000 feet below the ocean surface. This photo was taken from a NASA DC-8 by Ted Scambos, Lead Scientist at the National Snow and Ice Data Center. Note: Thanks to a spring-break getaway, I`m just now catching up to this new research showing that warming ocean waters are threatening the stability of giant, floating...

Federal Environment Minister won’t say if Canada can develop oilsands and meet climate targets

Calgary Herald: Canada`s environment minister won`t say if the country can meet its climate change commitments and at the same time green-light new pipeline projects.

Study questions China’s CO2 emissions dip

Climate Central: China's greenhouse gas emissions are on a downward trajectory, but its emissions may not have fallen quite as much over the past two years as the Chinese government and the International Energy Agency have suggested. That's the conclusion of a new study published in the journal Nature Climate Change, which says China's emissions may have actually increased in 2014, rather than fallen. The International Energy Agency estimated last year that both the decline in China's coal use and falling electricity...

Cold War-era Alaskan tunnel yields clues on climate

ClimateWire: Ten miles north of Fairbanks, along a man-made valley cleared by industrial gold dredgers in the early 1900s, a small red building at the base of a hill provides a portal to the geologic history of central Alaska. Behind a locked metal door lies the Cold Regions Research and Engineering Laboratory, a 360-foot tunnel that gives scientists hands-on, underground access to frozen permafrost dating from the present to nearly 50,000 years in the past. Operated by the Army Corps of Engineers and the...

$1tn could be wasted on ‘unneeded’ new coal plants, report warns

Guardian: Almost $1tn of investment in new coal-fired power stations could be wasted if growing concerns about climate change and air pollution leave the plants unused, according to a new report. About 1,500 new coal plants are in construction or planning stages around the world but electricity generation from the fossil fuel has fallen in recent years, the detailed report from the Sierra Club, Greenpeace and CoalSwarm found. In China, existing plants are now used just 50% of the time, coal use is falling...

Irrigation district intervenes in Rio Grande water lawsuit

KCBD: The board of directors for one of New Mexico's major irrigation districts has voted to intervene in a lawsuit concerning decades-old permits and the authority to pull water from the Rio Grande.
