While large parts of the world saw record breaking heat in July, and Antarctic sea ice extent remained at record daily lows as assessed over the satellite record, Arctic sea ice extent for July was only the twelfth lowest in the satellite record.

Late June ushered in a significant shift in weather and melting for Greenland, particularly for the southern portion of the ice sheet, known as South Dome, where melting is currently on a record pace. Melting along the northern rim of the ice sheet is also greater than average.

The longest day of summer has come and gone, and summer melt is in full swing, with the pace of ice loss overall about average for this time of year. Arctic sea ice extent for June was not exceptionally low compared to other recent years.

Feature Story
In July 1879, the USS Jeannette left port in San Francisco en route to the North Pole. What lay at the top of the world was still shrouded in mystery. Was it a warm inland sea, a sheet of ice, or open ocean? The crew set out to find out. The majority of the crew of the USS Jeannette perished during the journey, but their memory lives on through the invaluable scientific information that they laboriously collected and returned to civilization.

Analysis - Ice Sheets Today
The melt season for the Greenland Ice Sheet has been near-average so far, with cool conditions in northern Greenland despite warm weather in nearby Arctic Canada. A small region of the ice sheet may not be properly mapped as it shows a higher number of melt days than is likely considering the observed weather for that area.
