In April, I pointed out that PIOMAS forecasts for the summer didn’t make much sense.IOW: AGW = TFBS.
The computer model is predicting that 3+ year old ice (which is probably in excess of 10 feet thick) is going to melt by early August. That seems rather far fetched.
It is now early August. Let us see how they did. They expected most of the ice to be gone in the Beaufort Sea by now, and much of the remaining ice to be very thin.
The most recent NSIDC newsletter included this map, showing that the thick multi-year ice is still present in the Beaufort Sea. This is in stark contrast to the PIOMAS prediction of thin ice in that region.
This discrepancy will get worse through the remainder of the month. PIOMAS extent/thickness predictions are way off the mark, and their volume calculations are much too low.
Conclusion : There will probably be minimal ice loss during August. The minimum is likely to be the highest since 2006, and possibly higher than 2005. So far, my forecast of 5.5 million km² is looking very conservative. Ice extent is higher than I predicted for early August.
