Yesterday I looked at JAXA data and ventured that:
The Sept 15th JAXA Arctic Sea Ice extent graph was published this evening about 8PM PST (and updated overnight which is the image now shown) and shows an increase in sea ice for the second day in a row. It seems clear that Arctic sea ice is now on the rise.
The Sept 14th value was: 5,276,563 km2
You can see this minimum and upturn clearly in the zoomed graph below.
I expect this JAXA value will increase again in about 4 hours once JAXA finishes QC and final data analysis. I’ll post an update when it happens (assuming it is not too late). (UPDATED 7:45AM PDT) 9/16)
Here’s the table of data:
Barring an about face by Nature, the 2009 Arctic Sea Ice minimum occurred on Sept 13th with 5,249,844 km2
UPDATE: WUWT reader Bruce Richardson made a nice zoomed comparison graph, which he offered in comments, that I have added to this article.
