Climate science: Understand Arctic methane variability

How measurements provide the basis to understand climate variability

Arctic tundra fires: natural variability and responses to climate change

© The Ecological Society of America www.frontiersinecology.org A surveying scientists working in the Far North for tundra-fire observations and examining Canadian Government fire records, pioneer Arctic ecologist Ross Wein concluded that “tundra fires occurred infrequently, and were invariably small in areal extent... Little is known about the ecological significance of tundra fires” (Wein 1976...

Science and Culture: Arctic photographers bring climate change into focus.

In 2009, a hunter shot a polar bear and carried it by dogsled about 750 meters to the town of Ittoqqortoormiit on the eastern coast of Greenland. Typically, the town’s hunters encounter polar bears on distant sea ice a couple of hours or even days from town. They skin their catches and leave behind the heavy bones. But as climate change melts more sea ice—the bear’s preferred hunting grounds—po...

Strong atmospheric chemistry feedback to climate warming from Arctic methane emissions

[1] The magnitude and feedbacks of future methane release from the Arctic region are unknown. Despite limited documentation of potential future releases associated with thawing permafrost and degassing methane hydrates, the large potential for future methane releases calls for improved understanding of the interaction of a changing climate with processes in the Arctic and chemical feedbacks in ...
