Temperature North of 80 Rollercoaster

Published on by sunshinehours11 Comment

At the beginning of the year the DMI “Daily mean temperatures for the Arctic area north of the 80th northern parallel” was a few degrees C above normal.

And then it went about 12C above normal. That coincides with the Arctic Sea Ice Extent falling out of the one standard deviation point it was in on day 26

In the last week or so it has plunged back down to 7C above normal, and it looks like it will continue. I wonder what will happen?

Published on by sunshinehours1Leave a comment

Did you know Global Sea Ice Extent is 900,000 sq km above the 1981-2010 mean?

Yes, Arctic Sea Ice Extent is 580,000 sq km below the 1981-2010 mean.

But Antarctic Sea Ice Extent is 1.47 million sq km above the 1981-2010 mean (the 2nd highest on this day ever).

Arctic Sea Ice Volume Up 50% From 2012

Published on by sunshinehours1Leave a comment

Arctic Sea Ice Volume in 2013 Up 50%. (h/t NorthWest Passage 2013 blog)

“Measurements from ESA’s CryoSat satellite show that the volume of Arctic sea ice has significantly increased this autumn.

The volume of ice measured this autumn is about 50% higher compared to last year.

In October 2013, CryoSat measured about 9000 cubic km of sea ice – a notable increase compared to 6000 cubic km in October 2012.”

“90% of the increase is due to growth of multiyear ice”

“This year’s multiyear ice is now on average about 20%, or around 30 cm, thicker than last year.”

“the volume of ice year-to-year was not varying anything like as much as the ice extent”
