The National Snow and Ice Data Center has been tracking Arctic Ocean sea ice extent for many years, and yesterday released new data on the extent of Arctic sea ice, compared to the 1981-2000 average for this time of year:
As you can see, the 2015 Arctic Ocea sea ice extent has consistently fallen […]
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 […]
If the surface area of sea ice in the Arctic is the same as it was at the beginning of last year’s record-breaking melt, but the ice is thinner than it was then, the conclusion is clear. There’s even less volume of ice in Arctic waters right now than there was at this time last year, meaning that less energy will be required to melt it down to last year’s record-low surface area. […]
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 National Snow and Ice Data Center has released satellite data showing that with the extent of ice in the Arctic Ocean is nearing its yearly minimum, the area of the Arctic Ocean covered by ice is at its third lowest in the historical record:
The extent of ice in the Arctic Ocean is […]
The climate of the Arctic Ocean is changing dramatically. A summary of findings from the past month:
Scientists have found methane plumes emerging from seabed permafrost north of Russia at rates 100 times higher than normal. The area of the Arctic Ocean that melted this year was the second-lowest ever, barely missing the massive record […]
