Arctic sea ice / Re: Latest PIOMAS update (May mid-monthly update)
« on: June 01, 2018, 09:20:53 PM »
so I'm not sure what Tenney's on about.

Glad I am not the only one.  I did wonder if we were just talking past each other.


How are you ruling out slow rate of decline now the MYI is down to minimal levels (and FYI replaces itself each winter) and some natural variability?

I am not taking your point, crandles.  I have been saying for many years that PIOMAS cannot be right, that the increases in volume from the low must be due to problems with the algorithms.  Of course, there might have been some increase due to natural variation, but the consistent increase over several years cannot have been right, IMO. Tell me how the water-logged slush can be measured in the same way that a similar section of tightly compressed multi-year ice can?  Further, slushy ice cannot be same temperature.  And, there is the stuff that resembles swiss cheese.  How is that being handled?

This seems based on assuming a rapid rate of decline and therefore does not appear to address the issue at hand of how to rule out slow rate of decline and some natural variability.
