Melting polar region

Both Antarctica and the Arctic are getting less icy because of global warming, scientists said on Thursday in a study that extends evidence of man-made climate change to every continent.

Detection of a human cause of warming at both ends of the earth also strengthens a need to understand ice sheets on Antarctica and Greenland that would raise world sea levels by about 70 meters if they all melted, they said.
