NOAA Probes Arctic Pollution For Global Warming Clues
NOAA — April 7 — NOAA scientists are now flying through springtime Arctic pollution to find out why the region is warming - and summertime sea ice is melting - faster than predicted. Some 35 NOAA researchers are gathering with government and university colleagues in Fairbanks, Alaska, to conduct the study through April 23. Called ARCPAC (Aerosol, Radiation, and Cloud Processes affecting Arctic Climate Change), the project is a NOAA contribution to International Polar Year 2008.

Ringed seals key to polar bears' fate: researchers
Winnipeg Free Press — April 4 —Ringed seals could help unravel the mystery of why polar bears are disappearing in Hudson Bay, ecologist Steven Ferguson believes. He is heading a two-year project to monitor the movement of the seals, which are the bears' major food source. Ferguson's work is associated with the federally funded global warming and Arctic marine mammals research project, part of the International Polar Year program.
