Summary:Every year, we report on the melting and growth of Arctic sea ice, the vast sheath of frozen seawater floating on the Arctic Ocean and its neighboring seas. Much attention is focused on the area and extent of sea ice because it has been shrinking steadily. But there is another problem: as the ice extent has shrunk, the oldest and thickest ice has either thinned or melted away, leaving the sea ice cap more vulnerable to the warming ocean and atmosphere.
