As a further comment Piers says [note typos amended from original and images added] :
” While recognising the huge amount of clever quality work and measurements, interesting calculations and massive resource back-up which have gone into these studies by the scientists involved, when one sees what is actually being said and the uncertainties it is beyond belief that the matter of some things that MIGHT be happening to the West Antarctic ice sheet get elevated to the level of international news to be used to add justification to modify the world economy in the name of the delusion of global warming.
Piers’ 7 Key points:
1. WHAT ARE WE TALKING ABOUT?
Answer in the abstract above 0.25mm (Maybe) sea level rise per year ie one inch in the next 100 years. NB ANY figure may be controversial. It’s not surprising there was not a headline saying this was the issue!!!!!!!!
It is important to note the media reportage of the matter is much more forthright and doom-claiming than the actual studies which admit uncertainties.
2. The studies or at least reportage of them assume ongoing Global Warming which is a delusion. IT IS NOT HAPPENING – see the pdf and link therein.
3. The studies only tell a fraction of the story. TO MAKE ANY SENSE THEY MUST
a) Admit the Antarctic ice as a whole is increasing.
b) Take the difference therefore between Antarctic Ice Gain and the projected (controversial) loss in West Antarctica. The answer could well be a net increase in ice NOT decrease – ie sea level fall not rise.
c) Consider the possibility that any loosening of the ice-grip which might be leading to extra ice flow off the West Antarctic shelf into the sea could be due to undersea volcanoes. NOTE as a FACT volcanism goes up in low solar activity periods ie Mini Ice Ages so in addition to (5) below [winds=>currents driven by MIA conditions] there could well be MIA expression volcanism involved here.
4. The authors should admit there is NO EVIDENCE that what is happening is anything to do with CO2. THAT IS JUST A POLITICAL DELUSIONAL ADD ON. To make this clear re-note
(i) They admit ocean currents are involved not surface temps which are the normal measures of claimed CO2 (delusional) effect.
(ii) CO2-warmists admit that CO2 fails totally to explain the wild jet stream in recent years and now, which is being invoked as a driver of the ocean current changes.
(iii) Extra Undersea volcanoes if involved are a signature of MIA (low solar activity) conditions nothing to do with CO2.
It ill-behoves the authors and associates of the these high-quality papers and related research to allow their work to be be-smirched with delusional CO2 nonsense the relevence of which there is NO EVIDENCE FOR – ONLY EVIDENCE AGAINST.
5. The papers / reviews mention that increased wind speeds in / near Antarctica may be driving the extra ocean currents which may be causing POTENTIAL increased rate of slippage of The West Antarctic ice sheet into the sea.
(NB these things are always moving so the changes in rates are the issue and to conclude they know something extra is really happening has large uncertainties. The desire for an alarmist conclusion is political).
THIS WIND DRIVER through Atmosphere-Ocean coupling of course is a MINI-ICE-AGE change in circulation effect which is solar driven (as evidenced by WeatherAction successful forecasts and the admitted inability of CO2 models to predict ANYTHING about circulation / jet stream changes in recent years)
6. Why the West Antarctic Slippage / BreakUp will probably never ‘take-off’:-
a) Since the wild Ocean currents which are thought to be giving the POTENTIAL for slippage and breakup occur at times during and are a consequence of Mini-Ice-Age circulation these same Ocean currents will end in their effectiveness when the present MIA (also known as “Wild-Jet-Stream-Age to reflect our understanding of its nature) ends. This is in about 30 years time. THE TIME IS NOT LONG ENOUGH to allow the West Antarctic slippage to develop.
b) The time scales involved in the models (without the party pooper just above) are 200 to 900 years and so considerably longer allowing for the fact that it appears MIA conditions are needed for the slippage. If slippage just happens during MIAs and stays ‘normal’ without recovering outside MIAs (which in fact it probaly would) this time would go up (at least) ~5 fold (the ratio of time between MIAs to MIAs) giving at least 1000 to 5,000 years. In that time the Earth will probably be entering a full ice-age and the Antarctic considerably larger not falling into the sea.
7. IF THERE IS ANY REAL OR POTENTIAL BREAK-UP AND SEAWARD SLIDE OF THE WEST-ANTARCTIC ICE SHEET GOING ON IT IS A Mini-Ice-Age / Solar-Lunar Action Technique EFFECT and CO2 has no role whatsoever
