First Hole in North Pole Ice Drilled by Explorers

A group of Arctic explorers has made the grueling journey to the North Pole and drilled a hole in the ice to take the first ever sample of ocean water at the pole in an effort to better understand the impacts of climate change. The explorers, part of a group called the Catlin Arctic Survey, completed the sampling expedition after failing to last year, reported the Guardian. The team reached the geographic North Pole on May 12 after a 60-day trek across the frigid Arctic ice.

EPA Announces Thresholds for Greenhouse Gas Permitting Requirements

U.S. EPA Assistant Administrator Gina McCarthy held a press conference today to discuss the EPA’s final rule to address greenhouse gas (GHG) emissions from the largest stationary sources, while shielding millions of small sources of GHGs from Clean Air Act permitting requirements. The phased-in, common-sense approach will address facilities like power plants and oil refineries that are responsible for 70 percent of the greenhouse gases from stationary sources.

Tracking Grizzly Bears

Keeping track of where wildlife may wander may give important keys on how they live and prosper as well as how to maintain their lifestyle. Rural areas with human development can lessen grizzly bear survival, and innovative bear rub tree surveys can successfully monitor grizzly population dynamics in the Northern Continental Divide Ecosystem, suggest two new studies released by the U.S. Geological Survey in the Journal of Wildlife Management

British Antarctic Survey census of biodiversity sheds light on changing climate

The British Antarctic Survey (BAS) presents the results of its ongoing census of marine life in the Antarctic at a meeting of the American Association for the Advancement of Science. The BAS census has been documenting the diversity of marine life in Antarctic waters and the way it is changing in response to climate change.

Climate accord offers some grounds for hope

The UN Climate Change Conference ended on Saturday (19 December) with frustration and verdicts of failure from many delegates because it did not reach a binding agreement on how to tackle climate change — or any agreement at all on targets for carbon emissions. But some commentators say that important principles behind fighting climate change have been established for the first time, and some action could start immediately even without the existence of a universal agreement.
