October 17, 2014 by Roman Kilisek

The Arctic and the Military

Even though these developments seem to push military security on the US Arctic agenda, it better serves US interest to comprehend Russia’s moves in the Arctic as rational and expand the use of confidence-building measures, as well as prioritize climate change during its Arctic Council Chairmanship.[read more]

Earth at Boiling Point

June 15, 2011 by Sam Carana

As long as no tipping points are crossed, many believe, there will only be insignificant rises in temperature and sea level, while any dangers are far away in the future. However, the boiling point analogy may more appropriately describe the risk of Arctic methane releases, and the window of opportunity we have to act.[read more]

Arctic Oil and Gas: The Emerging Question

February 15, 2011 by Emily McGlynn

“What would happen if a Deepwater Horizon-type oil spill were to happen in the Arctic?” is a question Arctic coastal nations have been asking themselves for almost a year now. It is important to stress that this is not a high-flown hypothetical. The USGS released a report in 2008 saying that there could be up to 400 billion barrels...[read more]

Open Waters Around Normally Frozen Baffin Island this New Year

January 4, 2011 by Simon Donner

At a casual meal on the weekend, I met a couple in town from Iqualit. The capital of Canada's northern Inuit territory of Nunavut is located on Frobisher Bay in southern Baffin Island. They told me that when they left home in mid-December, the ice on Frobisher Bay was not frozen. I almost coughed up my food; that can't be possibly be...[read more]

Arctic Sea Ice Melt Season Ends, with Ice Continuing its Recent Sharp Downward Trend

September 29, 2010 by Andrew Freedman

After a false alarm earlier this month, the 2010 Arctic sea ice melt season has come to a close, with sea ice extent reaching the third-lowest in the satellite record. This continues the steady and steep decline in sea ice cover during the past few decades, which scientists have traced mainly to emissions of greenhouse gases, as well as...[read more]

What the Battle Over the Arctic National Wildlife Refuge Tells Us about Public Opinion and Climate Change Legislation

September 17, 2009 by Tim Hurst

A study about attitudes toward drilling for oil in the Arctic National Wildlife Refuge sheds some light on how conservationists might influence public opinion in favor of climate change legislation. When the United States Congress finishes its work on health care this Fall, the next big challenge it will take on will be climate change...[read more]

Newsweek’s Science Editor explains why climate change is “even worse than we feared” and how “a consensus has developed during IPY that the Greenland ice sheet will disappear.”

August 5, 2009 by Joseph Romm

Among the phrases you really, really do not want to hear from climate scientists are: “that really shocked us,” “we had no idea how bad it was,” and “reality is well ahead of the climate models.” Yet in speaking to researchers who focus on the Arctic, you hear comments like these so regularly they begin to sound like the thumping refrain...[read more]

GOTW: Ice extent

On September 15-16, 2007, at the time of the Arctic sea ice minimum, relatively...[read more]

The title of this post is one of the scariest numbers I’ve run across in my energy and environmental research is a long time. Nine hundred billion metric tons. What is it? That’s the trend of net ice loss from the Arctic every year over the last few years. That’s 900 cubic kilometers of ice. Every year. (Drive down a straight, flat...[read more]
