Latest poll to see how we think the Arctic sea ice melt season will go this year. Extent has generally been hovering around 2nd to 5th lowest over the last few weeks.

As before, the data will be based on the NSIDC extent measures. They provide excel spreadsheets here that contain all of their daily data. Below are the values for the last 10 minima, in millions of km2

Opted for 4.0+ based upon the apparent large extent of ice still in the Central Arctic basin.

To get below 4.0K Km2  we will have to see some reductions in this area.

Just thought I'd add that from the previous poll, the average of 22 votes was 4.1 million km2, with a 90% range from 2.5 to 5.7. So a pretty broad spectrum of guesses.
