Pinpointing the minimum
UPDATE September 16th: Given another uptick and the current weather forecast, I'm ready to call the minimum for IJIS SIE V1 on September 12th at 5,000,313 km2. Apparently the high was too big and the pressure gradient too low to prolong things (see below). --- This blog post should perhaps ha...

Perception of the Arctic 2
Like I've written in the previous blog post with the same title, I'm not just interested in the science/ observation of Arctic sea ice and the consequences of its loss, but also in the question how and how far these events are finding their way to the collective consciousness. Are people becomi...

ASI 2013 update 2: shaken and stirred
During the melting season I'm writing (bi-)weekly updates on the current situation with regards to Arctic sea ice (ASI). Central to these updates are the daily Cryosphere Today sea ice area (SIA) and IJIS sea ice extent (SIE) numbers, which I compare to data from the 2005-2012 period (NSIDC has ...

The Four Charts That Really Matter
Guest post by R. Gates Recently on Judith Curry's blog, a guest post was submitted by DocMartyn which was a rather nicely (from a math perspective) done extrapolation of past tropospheric temperature trends and cycles out to 2040 and beyond. It was essentially a nice job of, as he put it, "gra...
2.2 M km^2
And smaller next year, close to zero.
It seems that a good number of folks both here and elsewhere have been influenced by the cool weather this spring in North America and Europe. The Arctic temperatures have not been colder than normal, however -- see http://polar.ncep.noaa.gov/sst/ophi/color_anomaly_NPS_ophi0.png
So my guess is that we will set a significant record, given the thinness of the ice and likelihood of an increase in feedback effects. It is going to be a pivotal year.

How does the collective wisdom of Arctic Sea Ice blog participants compare with expert scientific analysis in forecasting the September sea ice extent? This question seems worth exploring with a crowd-source experiment. You are all invited to submit, as comments to this post, your best guess for...

FWIW, I have been looking at the Fram each day using Worldview and calculating the speed at which ice is moving. For most purposes, you can use an average of 10 miles per day. It sometimes is more.

Following up on SATire, the Ellesmere crack appeared rather suddenly between Jan 21 and Jan 22. Overlaying the wind speed and direction for those days on the same chart shows that there was a substantial onshore wind which bifurcated to the east and west more or less along the crack line. I suppose that wind, which seems unusual to this novice, created the stress which broke the ice.
