By Victoria Gill – BBC News – May 10, 2013Three species of migratory duck have shifted their wintering grounds northward in response to increasing temperatures, say scientists. The birds - the tufted duck, goosander and goldeneye - are common in Britain and Ireland during northern Europe's winter. But their numbers in these countries have shrunk in the last 30 years. According to the findings, published in the journal Global Change Biology, many now stop short on their annual journey. Gathering and analyzing data from the three-decade-long International Waterbird Census, the researchers found many birds were staying closer to their summer breeding grounds all year round.

Restore America's Estuaries – March 2013
Coastal blue carbon refers to the greenhouse gas benefits of tidal wetlands, including salt marsh, seagrass, and mangroves. These ecosystems are highly proficient at removing carbon dioxide from the atmosphere and storing it in wetland soils. Recognition of the greenhouse gas benefits of protecting and restoring coastal marine ecosystems can increase the scale and pace of restoration. |

The amount of vegetation in the world, and the way it is spread across the planet, has changed significantly in the last three decades, researchers say. They attribute more than half the changes they detected to the effects of the warming climate, with people responsible for only around a third. Surprisingly, perhaps, they are at a loss to attribute about 10 percent of the changes unequivocally to either the climate or us. For full story, click here. |

Senior US government officials are to be briefed at the White House this week on the danger of an ice-free Arctic in the summer within two years. The meeting is bringing together Nasa's acting chief scientist, Gale Allen, the director of the US National Science Foundation, Cora Marett, as well as representatives from the US Department of Homeland Security and the Pentagon. This is the latest indication that US officials are increasingly concerned about the international and domestic security implications of climate change. For full story, click here.

By Brent Martin – Nebraska Radio Network – April 25, 2013An assessment on how climate change might affect Nebraska agriculture would be conducted under a bill moving forward in the legislature. LB 583 advances, though some lawmakers cast doubt on whether man-made activities have spurred climate change. Sen. Scott Price of Bellevue tells colleagues there’s no doubt the climate is changing.

Science Codex – April 18, 2013
A team of geoscientists from Southwest Research Institute (SwRI) using newly available remote-sensing technology has achieved unprecedented detail in quantifying subtle, long-period changes in the water levels of shallow lakes and ponds in hard-to-reach Arctic wetlands. Analysis comparing time-lapsed, high-resolution satellite imagery of the Ahnewetut Wetlands in Kobuk Valley National Park, Alaska, revealed an accelerated loss of surface water in shallow thaw lakes and ponds over a recent 27-year period compared to the preceding 27-year timespan. Those periods generally coincide with a well-known cooling and warming cycle known as the Pacific Decadal Oscillation, whose period is about five decades. For full story, click here. |

By Kevin Knobloch –Christian Science Monitor – April 18, 2013Despite the evident risks of climate change – from sea-level rise and coastal flooding to crippling drought – Congress has been slow to respond. Fortunately, states have given us reason for optimism by taking the lead on reducing heat-trapping emissions from fossil fuels. California, for instance, just launched its cap-and-trade system for reducing global warming pollution. The program was passed under a Republican governor and is being implemented by a Democratic one. The state also has the country’s most ambitious renewable electricity standard, which requires utilities to provide 33 percent of their electricity from renewable sources by 2020.
