UW has released the data for Julys Arctic sea ice volume estimate.

July 2018 has come in at 10309 km3 which is the 6th-lowest for the month in
the data series.

The top10 lowest Arctic sea ice volumes are now:

Year Month Vol (000s km3)
2017 7 9.141
2012 7 9.264
2011 7 9.546
2010 7 10.244
2016 7 10.257
2018 7 10.309
2013 7 10.538
2015 7 11.649
2014 7 11.951
2007 7 12.119

From the sea ice extent released by NOAA a few days back and PIOMAS ice volume we can estimate an
"average thickness".

July 2018 comes in at 1.2541 m "avg thickness" over the area of Arctic
sea ice, making it the 4th-lowest reading for the month in the sat-based
record.

The top10 lowest sea ice thicknesses are now:

2017 1.1513
2012 1.2078
2011 1.2365
2018 1.2541 <-- new #4
2010 1.2694
2016 1.2918
2013 1.2962
2015 1.3901
2014 1.4736
2009 1.5151

No surprise the rankings of ice thickness estimates and avg global temps
are closely related. We should also note the ranking of thickness is
closer to data series with good polar representations (e.g. NASA's
GISTEMP or Cowtan & Way's adjusted HadCRUT) rather than series
with poor polar representations (e.g. Hadley's HadCRUT).

Hayne blame game: banks' misconduct to blame for confidence slump, not
royal commission
ABC Analysis, 06 Aug 2018
The quiet but concerted campaign to ensure the royal commission into the
banks is stopped in its tracks follows a perverse logic that ignores it was
Australia's banks that caused the sector's reputational damage, not the
exposure, writes Ian Verrender.

... that hillBillyBot tabulated *all* the way back to 2007.

That's 6th-lowest out of the 12 values listed ... aka: right in the
middle of the sample.

How shocking!! /sarc
