NSIDC has provisionally announced that Arctic sea ice extent has recorded the lowest maximum in the satellite record.

This has naturally set the media off ringing alarm bells, like this silly one from Climate Home, “Arctic sea ice fell to its lowest winter extent in recorded history”

 

The reality is much more boring. According to NSIDC themselves, maximum extent this year has dropped from 5.612 to 5.607 million sq miles since last year. Such a small amount must be well within the margin of error, although these are not published.

 

Far from collapsing, Arctic sea ice area has been remarkably stable in the last decade.

And with multi year ice continuing to recover from 2008 lows, ice volume has also been growing in the last few years.

But it is no longer a case of science, when Ted Scambos, lead scientist at the NSIDC, can say

“The Arctic is in crisis. Year by year, it’s slipping into a new state, and it’s hard to see how that won’t have an effect on weather throughout the Northern Hemisphere,”

    The clue is in the name “SCAM”, just needs another “S” to make it perfect- “Scamboss”.

    Satellite data all the way back to 1979. What about all that loss of sea ice during the 1920s in the Arctic…back before CO2 started doing its thing? It could be seen from shipboard.

    NSIDC ice extent is a funky number. Defined as 15% of a satellite microwave pixel is ice. Which means 85% is open ocean. So how compact the sea ice ‘edge’ is (wind, currents) greatly affects extent. Much warmunist ado about nothing, as DMI says the average Arctic temperature was about -20C in February 2016. That is warmer than the usual -35C. But sea ice forms at -2C.

    Percent difference formula yields: ((5.612-5.607)/5.607)*100 = 0.089% difference..
    Yawn. Not a crisis. In a sane world not even news.

    Here are some maps and graphics that worth taking a look: http://www.arctic-warming.com/?page_id=14/. They analyse what had happened in the Arctic Region in the past, I hope you’ll find it interesting.

    So after a big El Nino there’s a bit less Arctic sea ice compared to the same time last year. Why is that even a surprise, let alone an alarm?

    Let’s see how the next few years go with no El Nino to distort the picture.
