The people from PIOMAS have done an extra data release (there'll be another one next week for all of the August data). This data shows us that yet another record domino has fallen, after so many others already. This is one of the biggest dominoes out there, especially now that observational data from CryoSat-2 is largely confirming PIOMAS modeled data. It's all about the volume.
Here's the graph that clearly shows the new record:
Here is Wipneus'
version with the calculated "expected" 2012 values (dotted
lines), based on the same date values of 1979-2011 and an exponential
A caveat from Wipneus: "Note that the statistical error bars are quite large."
Statistical error bars aside, the trend line follows the dotted forecast line almost to a T.
Here's Larry Hamilton's excellent bar graph:
The anomaly has come up some more (thank goodness):
As has the PICT graph, my crude method of dividing PIOMAS volume numbers by Cryosphere Today area numbers to calculate the ice pack's average thickness. This is just an indication that allows us to compare with previous years:
The average thickness is just as low as 2010 and 2011, but that's also because the current total area is respectively 791 and 603 thousand square kilometer smaller. There's a lot less ice than there has been for a long, long, time.
The Polar Science Centre now also has a thickness map on their website:
This record has been broken, just like all the others, but minimum hasn't been reached yet on most of the charts. We now await those. We also patiently await a record on the IMS sea ice extent chart (the last ice floe fake skeptics try to stand on), NSIDC September average extent, CT SIA anomaly, perhaps even CT global SIA and anomaly.
Records keep falling on my head...
