Physical measurements have demonstrated a negative bias to Antarctic temps for some time. Sea Ice area has demonstrated a negative temperature bias for some time. Well.............guess what? The models are not going to save Antarctica! onlinelibrary.wiley.com/doi/10.1002/2015GL066749/fullAh!!

Whoopie ... we're all saved!

www.trust.org/item/20160111070215-lzt7z/Jan 11 (Reuters) - Although the Arctic ice sheet gets all the media attention, noteworthy activity has been brewing in the Antarctic. The Antarctic ice sheet has stopped expanding for the first time in four years, and in fact, sea ice extent has dipped below average levels. The Antarctic ice sheet holds roughly 61 percent of the Earth's fresh water, and despite the mass shrinking of its Arctic cousin over the last decade, the Antarctic has experienced several periods of growth over the same time frame.

We'll have to watch these two carefully. If the Arctic ice extent starts growing while the Antarctic starts to decline, then? AMO going cold .... PDO may shortly go cold after the blob interlude and likely La Nina?? Then what can we say? Time to move to Chile???

Yeah, Kinda! Chile is like Southern California up to Canada upside down. Deserts in north ... tundra in south. In between .. good wine and a Mediterranean climate. Most stable country politically in South America. Some people 'flip' houses ... we 'flip' climates. Sovereign man likes Chile.

Antarctic ice is also looking weaker than many recent years.

Nino is not the friend of Antarctic Sea ice nor the land based Shelf's of Thwaits/P.I.G. with wind reversals increasing ice loss by driving warm waters under the Shelfs.
I also wonder if the rapid retreat of ice in Ross means action there over Southern summer?

El Nino is fading.
Planet always cools after this event.
Cooler planet means more ice.
Why is everyone worried about ice melting?
The next Ice Age is likely already actuarially reducing the expected lifespan of most members of homo sapiens.
Not sure about the sapiens bit!

I'm thinking that nino will fade to neutral only ( no Nina) as Northern summer skews global temps ( now the IPO is back into surface heating phase?).
This month saw us rise above 405ppm CO2, levels this high were last seen in the Miocene ( 15 to 33 million years ago ) starting at the time Antarctica first held ice fields ( 33 million years ago) so we enter into global condition that edge toward an ice free planet ( in time and should CO2 remain elevated)
As with the Perma Frost the frozen lands ( Greenland/Antarctica) also hold part of the old carbon cycle , entombed when the ice arrived, awaiting re animation.
last year saw CO2 rise by 5ppm, rather higher than the 2ppm we expected, this could be solely down to warmer oceans not able to absorb as much CO2 or may reflect the 4th " 1 in 100 year" drought to strike the Amazonian Forest since 2000? Whatever the cause to see CO2 levels accelerate when the world tries to slow gains must be of concern? ( to anyone knowing what CO2 does to global temps?)

I'm no expert, but I believe the Late Ordovician Period was also an Ice Age while at the same time CO2 concentrations were roughly 10 times higher than today.

This might help. Late Ordovician Glaciation occurred with several thousand ppm of CO2. "Settled science" would suggest that is impossible. Or perhaps our climate theory is a little incomplete?

View AttachmentThis might help. Late Ordovician Glaciation occurred with several thousand ppm of CO2. "Settled science" would suggest that is impossible. Or perhaps our climate theory is a little incomplete? More importantly from that chart the temperature has a ceiling at ~22C this would appear to indicate the presence of a strong negative feedback that operates at that 'global temperature' preventing excursion above it. This level of stable homeostasis falsifies catastrophic AGW.
