Earlier this month, DMI showed Arctic ice volume above the 2004-2013 average. I tweeted about this and copied BBC News, CNN, NPR and the New York Times.
Quite predictably, the data disappeared for three days, and now that it has returned, DMI has massively reduced the amount of sea ice in the Arctic. Much of the thick ice off the coast of Siberia has disappeared.
Now, just as Arctic sea ice extent was about to become the highest for the date in the past 17 years, the extent data has disappeared as well. This is what the OSI Arctic and Antarctic sea ice data looked like three days ago.
And this is what it looks like now. All the data after November 4 has disappeared.
According to NSIDC, Arctic sea ice extent is just below 2004 and 2014
