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.

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.

Ice (Re) Cap: June 2015

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.

    Seasonal ice-cover reduction throughout Arctic waters mapped

    Nowhere is climatic warming more evident than in the Arctic. Arctic air has warmed almost twice as much compared to the global average in recent decades, and Arctic sea-ice extent has hit historic lows in the last decade.

    Warm river water melted Arctic sea ice

    In September 2012, the area of the Arctic Ocean covered by sea ice was the smallest on record since satellite monitoring began in 1979. Several factors are thought to have contributed to that summer’s diminished ice, including a large cyclone in August that brought warmer ocean waters into the area and broke up the ice and a longer-term trend of thinning and weakening sea ice. Now, researchers have found that at least one large burst of warm freshwater into the Arctic earlier in the summer probably played a role as well.

    Bare Earth Elements: Cool time-lapse shows movement of ice and animals in Antarctica's Ross Sea

    Has anyone else been obsessed with Antarctica lately? As an erstwhile scientist with a lasting interest in the life that inhabits what we think of as extreme environments (not to mention the physical environments themselves), I’ve been gleefully soaking up details from the myriad news reports, blog entries and scientific studies coming out of the icy continent of late. The latest bit of fodder for my Antarctophilia is a 5-minute time-lapse video (below) taken from the icebreaker Nathaniel B. Palmer during a recent two-month stint in the Ross Sea.
