The Arctic freeze-up season is well underway, with ice extent increasing faster than average for most regions in November. Exceptions were in the Chukchi and Barents Seas, where the ice has been slow to form. Meanwhile, November snow cover over North America was the…
Arctic sea ice appears to have reached on March 7 a record low wintertime maximum extent. This is the lowest maximum in the 38-year satellite record. On the opposite side of the planet, on March 3 sea ice around Antarctica hit its lowest extent ever recorded by…
Analysis of climate conditions, conducted by NASA's scientists shows the global surface temperatures and Arctic sea ice extent during the first half of 2016 set new records and are continuing trends of change observed over the last few decades. NASA's…
A newly published study offers evidence that the negative phase of the Interdecadal Pacific Oscillation (IPO), which is characterized by cooler-than-average sea surface temperatures in the tropical eastern Pacific, has created favorable conditions for additional…
The sea ice cover of the Southern Ocean reached its yearly maximum extent on October 6, 2015. Sea ice cover at its maximum has spread across the area of 18.83 million square kilometers (7.27 million square miles), which puts it both on the 22nd lowest and 16th…
Satellite data show the Arctic sea ice minimum extent of the year 2015 is the fourth lowest recorded since the beginning of the observations from space.Researchers from NASA and the National Snow and Ice Data Center (NSIDC) at the University of Colorado at Boulder have
