On March 19 2015, the National Snow and Ice Data Center declared that sea ice in the Arctic Ocean had reached its high point in its area of coverage (“extent”) for the year, and that this high point was the smallest on record.
As you can see by following the blue line in this […]
From where I sit as I write this, I can look outside through a window, and see, even in the dim light of this early hour, that it is very snowy, and very cold, outside. It is easy to forget, in these conditions, that last year was the hottest year for Planet Earth in the […]
People who find it politically inconvenient to believe that global warming is real are taking glee at the suffering on board the MV Akademik Shokalskiy, a boat filled with climatologists that’s stuck in frozen waters near Antarctica. They’re writing articles suggesting that the existence of thick ice near Antarctica somehow suggests that global warming is […]
Ice cover on large bodies of water continues to decline across the north, in the Arctic, but also in the Great Lakes, according to a new report. […]
Earlier this week, the University of Washington’s Polar Science Center released its latest Arctic sea ice measurements to make them current as of September 15, 2010. The Polar Science Center uses a satellite to measure the three-dimensional volume of the Arctic sea ice (a approach different than that of the National Snow and Ice Data […]
The melting of the Arctic sea ice literally crossed another line yesterday, as the area of Arctic sea ice fell below the level of two years ago:
The collapse of the Arctic sea this year is only surpassed by the calamity of 2007. The four lowest years of Arctic sea ice extent are the […]
Last week, the National Snow and Ice Data Center reported:
Arctic sea ice appears to have reached its annual minimum extent on 10 September. The minimum ice extent was the third-lowest in the satellite record, after 2007 and 2008, and continues the trend of decreasing summer sea ice.
But appearances can occasionally be deceiving. After […]
The latest data on sea ice extent in the Arctic Ocean includes information up through October 27, 2009:

The National Snow and Ice Data Center’s standard for measuring a notable deviation from the 1979-2000 sea ice average is two standard deviations, which is a reasonably strong standard, […]
Don’t fear the data.
The latest data on sea ice extent — updated on Thursday October 29, 2009 to reflect the most recently available data, up through Tuesday October 27, 2009 — in the arctic from the National Snow and Ice Data Center:
This updated data shows that as of October 27 2009, there’s […]
Environmentalists need to consider the meaning of the ribbon seal ruling, which suggests that future conditions will often not provide a solid foundation for present-day action through the Endangered Species Act. […]
The National Ice and Snow Data Center has released its measurements of the extent of sea ice in the Arctic Ocean through the end of August. The area of the Arctic Ocean covered with ice is at its second-lowest point since measurements began (last year was the record):
The rate of sea ice loss […]
