NASA: Sea ice at poles is shrinking
WASHINGTON (WKRC) - The sea ice in the North and South poles is shrinking.
NASA scientists say the ice reached its lowest point since it started tracking it in 1979.
The highest level of sea ice was 37,000 square-miles lower than it was two years ago.
Scientists say warm temperatures, winds and storm activity played a role.
The South Pole saw its lowest level, but NASA isn't ready to blame global warming yet.
