Three penguin species that share the Western Antarctic Peninsula for breeding grounds have been affected in different ways by the higher temperatures brought on by global warming, according to Stony Brook University Ecology and Evolution Assistant Professor Heather Lynch and colleagues. The work by Lynch and her team is contained in three papers that have been published online in Polar Biology,Ecology and Marine Ecology Progress Series (MEPS).
Lynch and her colleagues used a combination of field work and, increasingly, satellite imagery to track colonies of three penguin species -- Adélie, chinstrap and gentoo. The Adélie and chinstrap migrate to the peninsula to breed, while the gentoo are year-round residents.

In 1996 the Polar Libraries Colloquy (PLC) passed a motion at its 16th meeting in Anchorage, Alaska establishing the Hubert Wenger award to commemorate Hubert's outstanding contribution to polar libraries. The award is funded though the proceeds of the Circumpolar Auction held at each Colloquy. Donations to the award are welcome.
The purpose of the award is to provide financial assistance to one or more delegates who might otherwise be unable to attend a PLC biennial meeting. The award covers the full cost of registration for the meeting. Funds are not available to cover any delegate's travel or accommodation costs. Delegates who have received two Wenger awards in the past are not eligible to apply for further funding.
To apply for an award, contact the PLC Secretary:
Applicants should provide the Secretary with:
If an applicant is from an organization that has recently attended a PLC meeting, it is expected that the applicant or his/her organization will have paid the latest PLC membership dues.

The Greenland ice sheet is likely to be more vulnerable to global warming than previously thought. The temperature threshold for melting the ice sheet completely is in the range of 0.8 to 3.2 degrees Celsius of global warming, with a best estimate of 1.6 degrees above pre-industrial levels, shows a new study by scientists from the Potsdam Institute for Climate Impact Research (PIK) and the Universidad Complutense de Madrid. Today, already 0.8 degrees of global warming has been observed. Substantial melting of land ice could contribute to long-term sea-level rise of several meters and therefore it potentially affects the lives of many millions of people.
The time it takes before most of the ice in Greenland is lost strongly depends on the level of warming. "The more we exceed the threshold, the faster it melts," says Alexander Robinson, lead-author of the study now published in Nature Climate Change. In a business-as-usual scenario of greenhouse-gas emissions, in the long run humanity might be aiming at 8 degrees Celsius of global warming. This would result in one fifth of the ice sheet melting within 500 years and a complete loss in 2000 years, according to the study. "This is not what one would call a rapid collapse," says Robinson. "However, compared to what has happened in our planet's history, it is fast. And we might already be approaching the critical threshold."
Canadians have donated about $10,000 to help keep a unique High Arctic research station from closing after its federal funding stops, says the Canadian Foundation for Climate and Atmospheric Sciences.
Shell has been training a dachshund and two border collies to detect oil spills beneath snow and ice.
