The Arctic Ice Death Spiral!

Visual image of the rapidly disappearing Arctic ice!
Note that extent last month was just the same as it was in April 2006.
Meanwhile, volume is back to 2006 levels
And thickness for most of this year is at its highest since 2006.

Despite a lower max this year is keeping pace with 2014, according to MASIE.

Yeh, Masie has ice free areas in Beaufort Sea:-

Whilst NOAA ‘Ice Desk’ seems to see it differently:-

I know, I know, is it 30% or 15% etc, but NOAA seems to be 7/10ths?
Anyhow, hey ho, on we go! So with the North looking good, warmer they say, and south getting rather a bit chilly, suppose it is good to have more land in the north?
I really don’t know why anyone should trust NOAA these days.
Thanks! A timely post for me that came during an argument with a Death Spiral moron that claimed the Arctic is losing ice “10 times faster than the Antarctic is gaining it”. I had proven my point on extent using Cryosphere today comparative images and Sunshine hours graphs but of course after that he claimed that volume was declining.
It really is both amusing and disturbing that so many people believe that kind of crap when such sites as these citing credible scientific sources exist.
So thanks again!
Thanks, Paul.
Arctic Sea Ice extension measurements started in 1953, and have been decreasing since peaking in 1970 to December 2012. Satellite measurements started in 1979.
See SOTC: Sea Ice (National Snow and Ice Data Center – NSIDC),
at https://nsidc.org/cryosphere/sotc/sea_ice.html
It has been on recovery mode since 2012, but the NSIDC hasn’t noticed yet.
Of course, as entertaining as it is to follow the twists and turns of Arctic ice extent, we should not forget the extent is a function of water, wind and cloud, not CO2 or air temperature.

Yes, of course. In my climate pages I show:
In the winter the Arctic sea ice more than doubles in size. Arctic sea ice extent is directly dependent on winds and currents, not just on temperatures.
Yep in many ways the Arctic is more dynamic than the Antarctic. Sea ice extent can change very quickly.
The Arctic is also land boundary restricted.
There are only a couple of sectors where it can increase above a certain maximum of sea ice.
Unlike the Antarctic, which is free to expand and expand… like it seems to be wanting to do.
Um, so what? The planet, polie bars, and we would do just fine without any sea ice. The peaks of civilization and biosphere have always occurred in warm periods. Disaster or even harm predicted by warmists is bogus. The current greening of the planet is just the first indicator. We may hope it’s not truncated by the end of the interglacial. We wouldn’t enjoy that, at all.
