Arctic sea ice extent has reached its seasonal minimum, dropping to the sixth-lowest level in the 35-year satellite record.
This year’s melt represents a significant gain in sea ice extent from last year — when the ice cover plummeted to a record low — but scientists cautioned that long-term trends are what is most important, with most projections still showing a seasonally ice free Arctic Ocean by the middle of the century, if not sooner.
In addition, measurements of sea ice volume are at near-record low levels, indicating that the ice cover is unusually thin and vulnerable.
Temperatures warmed into the 50s Wednesday. Patchy fog and moderate rain overnight followed by snow Thursday.
