Comment: Crazy times in the Arctic

As atmospheric greenhouse gas concentrations increase, the resulting warming and its effects are most pronounced in the Arctic, where last year’s sea-ice changes and temperature fluctuations are surprising even seasoned experts.

Wintering in the high Arctic reveals surprising results

A summary of the results of the winter 2015 Norwegian Young Sea ICE Expedition (N-ICE), during which the Lance, a Norwegian research vessel, drifted for six months with the shrinking Arctic sea ice reaching as far as 83 degrees north. More than 70 scientists from 10 countries participated in the second-only winter field survey of the Arctic ice pack, and what they found surprised them.

Ice (Re)Cap: October 2016

From Antarctica to the Arctic; from polar caps, permafrost and glaciers to ocean-rafted sea ice; and from burly bears to cold-loving microbes, fascinating science is found in every nook and crevasse of Earth’s cryosphere, and new findings are announced often. Here are a few of the latest updates.

Arctic climate change marked by warmer, wetter conditions

At least since satellite observations began four decades ago, climbing temperatures have chipped away at Arctic sea ice causing earlier spring melting and later autumn freezing. Because ice reflects more sunlight than water does, shrinking sea-ice cover means that Arctic waters soak up more solar energy, which affects climate both regionally and globally. Now, a new study has documented how Arctic warming leads to wetter air and increased cloud cover, particularly during autumn and winter, which spurs even more warming in a self-reinforcing cycle.

Benchmarks: August 3, 1958: USS Nautilus crosses the North Pole

As the USS Nautilus glided through the black depths of the Arctic Ocean, Cmdr. William Anderson asked the crew for quiet. A tense silence hung over the dull roar of the propellers and the sharp pings of sonar as the submarine closed in on its destination. “Eight … six … four,” Williams counted down over the intercom, accelerating as they got closer, “three … two … one …”

Endangered Icebreakers: The future of Arctic research, exploration and rescue at risk

A shortage of ice-breaking ships limits polar research efforts; complicates search-and-rescue efforts when fishermen, tourists or others are stranded in sea ice; and raises national security concerns. So far, though, the U.S., which has only two government-owned icebreakers, isn’t prioritizing funding for these important ships.

The Arctic is open for research

“Science knows no boundaries, and the issues that the Arctic region faces require high-quality, trans-disciplinary and problem-based research, something which cannot be accomplished solely at the national level.” So stated Annu Jylhä-Pyykönen, Finland’s Head of Delegation to the Arctic Council’s Task Force for Enhancing Scientific Cooperation (SCTF) in an interview published on the Arctic Council’s website in March 2015.
