Scientific efforts to find out what’s happening to the Arctic ice cap and to the polar bears who live there are continuing. In 2009, the Arctic Survey project plans to send a team of explorers to travel across the Arctic on foot, measuring the thickness of the ice. The team will be led by Arctic explorer Pen Hadow. The “on the ice” measurements will help scientists see what is actually happening and refine their computer simulations. Current predictions show the ice disappearing in the next 5 to 100 years, which will change the face of the Arctic completely. Read about the planned expedition — the Arctic Survey .
