Cato,
I think you have to view the DMI ice thickness figures with a degree of caution - as there seems to be a bit of disagreement between their prediction and those of Navy's HYCOM, as well as the last data reported by CryoSat
e.g. DMI seems to have a band of 4.5 m thick ice just north of Greenland and CA - which isn't present in either of these other 2 sources.
It also had the Kane Basin as being filled with ~4 m thick ice - but the latest MODIS images suggest this isn't the case
PIOMAS July 2016
Another month has passed and so here is the updated Arctic sea ice volume graph as calculated by the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) at the Polar Science Center: As expected after a month of stalling sea ice extent and weather that generally isn't conducive to se...
Rob, it was published. http://journals.ametsoc.org/doi/full/10.1175/2010JCLI3823.1
Crisis in the Cryosphere
I recently received an e-mail to draw my attention to a recent two-part feature article on the Scientific American website by Dr. John J. Berger, an independent energy and environmental consultant. The article called Crisis in the Cryosphere is about the changes going on in the world of ice and ...
Hi Neven,
While the JAXA numbers have been dropping slowly over the last week. There is a lot of blue on the Modis images and some of the areas previously covered by melt ponds in the East Siberian sea have already drained. The regional maps seem to be suggesting that a fair amount of ice has been transported back into areas of the AC and ESS that were previously cleared and have raised SST. So not really sure that it has been a "good" first week for sea ice in June.
PIOMAS June 2016
Another month has passed and so here is the updated Arctic sea ice volume graph as calculated by the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) at the Polar Science Center: As of May 31st the 2016 trend line is lowest on the graph. A sea ice volume decrease of 3037 km3 duri...
Bob,
It is highly unlikely that a highly published scientists such as Rignot (with a H-factor of 63 and 493 papers to his name) would agree to be a co-author on a paper that he found "highly questionable".Co-authorship is voluntary and the norm is to remove your name from a paper you disagree with.
Also reading the links you provide - I also can't see how you interpret what he said as highly questionable. Especially as he also stated:
"Hansen’s co-author Eric Rignot said in an email that the exploration of such extreme scenarios was justified “because they are not unlikely, and they are more likely than the more conservative scenarios branded by [United Nations] reports.” http://www.slate.com/blogs/the_slatest/2016/03/22/james_hansen_sea_level_rise_climate_warning_passes_peer_review.html
Beaufort under relentless (high) pressure
When I wrote the Beaufort under early pressure blog post last month, I didn't quite expect this unprecedented pressure (timing and magnitude) to keep up for so long. High pressure areas tend to be short-lived in the Arctic, but this one was still going strong when the Beaufort quick update was p...
Sorry – I meant to type “century” (as in one hundred) rather than "centaury" - the plant
ASI 2015 update 4: massive heat
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 2005-2014 period (NSIDC has...
Seems like 2015 has decided to play catch-up. Jaxa has report two centaury breaks over the last two days (112 and 163).
