Media Advisory: NSIDC Arctic Sea Ice Scientist at Press Briefing

NSIDC Research Scientist and Arctic sea ice expert Julienne Stroeve will join a panel of scientists on December 16 at 9:00 am Pacific Standard Time for a press briefing on Arctic change. Stroeve will discuss the emergence and implications of stronger warming in the Arctic compared to the rest of the globe, a process tied to the rapid decline of summer Arctic sea ice.

Please see below for call-in information for reporters not attending the Fall American Geophysics Union (AGU) Conference. Please contact Peter Weiss at or Maria-Jose Vinas at for more information on attending AGU with press credentials.

Press briefing details

The Arctic in Flux: New Insights from the International Polar Year

Continuing climate changes in the Arctic received renewed scientific attention during the International Polar Year (IPY), which began in February 2007. This briefing presents early results from a range of studies conducted during IPY based on climate models and new observations taken from sea, land, and space.

Findings include evidence that the predicted amplification of Arctic warming caused by decreasing sea ice has already begun (Stroeve); large increases in tundra greenness along North America's Arctic coasts (Walker); the discovery of new seeps of the greenhouse gas methane along the East Siberian Arctic Shelf (Semiletov); and a lengthening snowmelt season and a second year of ice mass loss in Greenland (Tedesco).
