2017 Arctic Sea Ice Minimum Extent Is Eighth Lowest on Record
Arctic sea ice appeared reached its yearly lowest extent on Sept. 13. Analysis of satellite data by NSIDC and NASA showed that at 1.79 million square miles, this year’s Arctic sea ice minimum extent is the eighth lowest in the consistent long-term satellite record, which began in 1978.
“The weather conditions in the Arctic have not been particularly noteworthy this summer," said Cryospheric Sciences Laboratory member Claire Parkinson. "The fact that we still ended up with low sea ice extents is because the baseline ice conditions today are worse than the baseline 38 years ago.”
