After over 2 months, new data from GRACE-FO - at last.

Updated GRACE-FO ice mass fromftp://isdcftp.gfz-potsdam.de/grace/GravIS/GFZ/Level-3/ICE/GIS

Last measurement date mid-November 2019.
12 month ice mass loss 479 GT, i.e. 1.32 mm sea level rise.

Note the precipitous loss in ice sheet mass in the south/central coast of West Greenland (basin 306) since around 2017.

The lower than average snowfall over the last month or so might show an uptick in the 12 month change in ice sheet mass in the next month or two.

For me it's simple: Humans have proven incapable of sufficient self control to forestall ecological disaster. So, Mother Nature will have to do it instead, and the sooner she does (incl. BOE), the less the long-term damage.

 GRACE-FO is producing new mass loss data that I can read. Also posted on what's new.

We will get a much better handle on what's going on from now on.

From the very first post in this thread, way back in March:

Personally, I think we will end up somewhere around 4,5 Mn km2 by the middle of September.

FWIW, it's now September and the current projected JAXA minimum (rounded to one decimal place) is in fact 4.5 million km2.  Not bad!

Well, one thing's for sure, the answer won't be given there.  ::)

I think this applies to many here

Maybe I am missing something, but that Slater projection for July 25 looks a lot more like the current ice extent from AMSR2 for June 5 (today) than it looks like, for example, the actual ice extent for July 25 last year (see below -- I've put all three maps together).  In addition to that, we are at the second lowest measured extent since 1979 for any June 5 right now, implying, at least, that ice extent should look something like last year's extent on July 25.  To me, the Slater forecast looks strange, and I would be glad to be enlightened.

AMSR2 image for July 25 2017 is a little smaller scale than the other maps... apologies.  Pattern of lower extent is still obvious, though.  No ice in Baffin Bay, Hudson Bay, Kara Sea, most of ESS free of ice etc.

Slater projection shows ice beginning to open in the CAB for July 25th, extremely close to the pole. Extent of 7.42 mil km^2 at that time.

I'm sure it will be too lefty and optimistic for some on here but I enjoyed the French doc called Demain (Tomorrow in English).

Are you thinking of Wendell Berry's:

“We thought we were getting something for nothing,

But we were getting nothing

for everything.”
