Media Teleconference: Exploring Sea Ice, Climate Warming Link

Researchers have suggested for some time that the icy surface of the Arctic's waters, or sea ice, is retreating because of an ever-warming climate. Sea ice is an indicator of changing water, air, and sea surface temperatures, and is important to the well being of Arctic mammals such as polar bears.

With the annual minimum perennial sea ice period less than a month away, a representative from the National Snow and Ice Data Center (NSIDC), Boulder, Colo., will present the latest on the state of summer Arctic sea ice. Scientists from NSIDC and NASA will answer questions such as: Is wintertime Arctic sea ice also showing significant signs of change? How might earlier spring Arctic sea ice break-up affect polar bear populations?

NASA hosts a teleconference for the media on Sept. 13, 2006 at 1 p.m. Eastern on this topic. This conference will be archived for a short time at 888-568-0871.
