Arctic sea ice forecast: it’s going to be tough to stay cool

Bad news from the Arctic is piling up as we head into the last few weeks of the melting season. The various measures of sea ice area, volume and extent are plummeting towards a new record minimum. I have therefore reviewed the history of Arctic sea ice melting seasons since 2007, and compiled my own forecast of how the rest of the year is going to pan out. Remember, you read it here first…

When Arctic sea ice area sets a new record low in the next couple of weeks, the usual suspects ((Being Watts, Goddard, Bastardi, Jo Nova, Delingpole, the GWPF, Morano and their NZ poodle, Richard Treadgold.)) will say: “You can’t trust area, sea ice extent is the only valid metric“.

When Arctic sea ice extent sets a new record low in September, the following arguments will be run in parallel:

  • There will be a frantic search for a definition of extent in which a new record was not set
  • There will be a complaint that the satellite record has been blighted by the failure of a sensor and the calibrations needed to get a new sensor in operation have corrupted the record ((With added bonus insinuations of fixing and fraud by “warmist” scientists.))
  • It will be claimed that it was all caused by the major Arctic storm that hit in August, and thus can’t be attributed to global warming ((In 2007, the record low was all down to winds, remember?))
  • It’s cyclical — it’s all happened before, in the 1930s ((Or pick a date (any date), based on an old press clipping reporting anecdotal evidence of ice loss.)), and is therefore nothing unusual
  • That it’s irrelevant, because it’s not global and not happening where anyone lives so can’t possibly matter.

When the sea ice extent and area anomalies blow out to record levels in early October because of the delayed freeze-up, there will be silence.

When the re-freeze starts, and the Arctic basin is covered in ice once more (early December), Anthony Watts will report on the record rate of ice formation, calling it a “stunning recovery“.

When a cold spell hits the Eastern US and/or Western Europe in December/January, caused by a major Arctic Oscillation excursion and the resulting big slow-moving loops in the polar jetstream ((A result of massive heat loss from the Arctic Ocean during the refreeze, see the work of Jennifer Francis, reported earlier.)), the usual suspects will cackle loudly that global warming has suffered another mortal blow from which it will never recover.

Long range forecast for the next five years, until the Arctic Ocean is ice free in summer? Rinse and repeat.

Greenland’s extraordinary summer #2: still melting

Petermann20120806

Greenland’s extraordinary summer is far from over. The ice island that broke off the Petermann glacier tongue last month — now dubbed PII-2012 — is edging its way out into the Nares Strait between Greenland and Ellesmere Island, as this satellite image, snipped from NASA’s fabulous daily Arctic Mosaic shows. For updates on events in Nares Strait, check out Dr Andreas Muenchow’s Icy Seas blog — he’s up there at the moment. Elsewhere on the great ice sheet, melting continues apace. Jason Box reports that ice sheet albedo has dipped again into record levels for the time of year, and there are reports of further extensive surface melting at the end of July. Box also reports that a recent update of the Greenland temperature record shows that current temperatures are unprecedented in at least the last 172 years. There’s also excellent coverage of the summer at Greenland melting.

Meanwhile, and rather unsurprisingly, New Zealand’s little band of climate deniers are insisting that there’s nothing special going on up North. And, equally unsurprisingly, they’re totally wrong.

When asses go to court

Perhaps the least interesting aspect of the High Court hearing which started today — the NZ Climate “Science Education” Trust (NZCSET) versus the National Institute of Water and Atmospheric Research (NIWA), before Justice Venning — is the ostensible casus belli, the construction of a long term temperature record for New Zealand. The law does not concern itself with trifles, and the minutiae of the techniques used to homogenise temperature records to account for site moves and instrument changes is nothing if not trifling with respect to the climatological big picture. New Zealand and the world have warmed significantly over the last 150 years, of that there is no doubt, and no amount of legal action will make warming go away and New Zealand’s glaciers recover the mass they’ve lost.

Nor has the the long term New Zealand temperature record been important to the formulation of government policy on climate change. That has relied on international diplomacy, the workings of the United Nations and the international consensus on the science of climate, all leavened with a healthy dose of local politics. The NZ temperature record played no part in either the design of the emissions trading scheme or its watering down.

So if this case is not about temperature records and their relevance to government policy, what is it about? We need to consider a few key questions.

  • Who is bringing the action?
  • Who is paying the lawyers?
  • Who wins, and who loses?

The answers are bad news for the taxpayers and citizens of New Zealand — and perhaps the world.

Shang a de Lange

Much exercised by the question of ocean warming, New Zealand’s most litigious temperature savant posts excerpts from an article on the subject, and thanks Waikato University’s Willem de Lange for introducing him to this “really clear treatment of ocean warming and ocean-atmosphere interaction”. Two things are interesting about Treadgold’s post, and neither has anything to do with the contents of that article ((Life’s too short, basically, to debunk an article of dubious provenance now 12 years old.)).

The piece, by oceanographer Robert E. Stevenson (deceased), was published in the summer 2000 edition of 21st Century Science & Technology magazine. This is interesting in and of itself, because 21st Century Science & Technology is is an organ of the Lyndon LaRouche movement, centred on an oddball and extremely fringe US politician. We last encountered LaRouche when exploring the footnotes in Ian Wishart’s remarkable climate book Air Con. Amongst many strange things, LaRouche believes that the President of the US and Prince Philip are conspiring to reduce the population of the world from 7 billion to 2 billion, and that financier George Soros is their henchman ((No, really. Check the link.)). 21st Century Science & Technology espouses what might be charitably described as non-mainstream views on many science-related subjects, from the “swindle of special relativity” to global warming as “hoax“.

Which leads me to the second interesting thing: does Waikato University’s Willem de Lange, one of the tiny coterie of climate sceptics still active in New Zealand academic circles, listed by his university as an expert on “tsunami and storm surge prediction and mitigation; wave-induced sediment transport; dispersal studies; climate change; oceanography”, really regard Stevenson’s article as a credible reference? Would he be prepared to defend this 12 year old article’s interpretation of the physics of ocean warming against his peers? Or was he perhaps just digging around for a little chum to throw to the less well-educated hordes who congregate around Treadgold’s pulpit desperate for anything to support an oddball contention, that ocean warming somehow has nothing to do with the increase in carbon dioxide in the atmosphere? You be the judge…

You might think that de Lange, Treadgold and Lyndon LaRouche make for strange bedfellows, but when you have nothing better to turn to, I suppose — as Steven Stills so memorably sang — you have to love the one you’re with. Rather a pity for all their credibility, what little might be left of it.

Still warmin’ after all these years (Prat watch #5.6)

1967withlines

Courtesy of Texas state climatologist John Nielsen-Gammon, a very nice graphical demonstration of why “warming” hasn’t stopped in the last decade (or two). Nielsen-Gammon took the GISS global temperature series, classified years as El Niño dominated, neutral, or La Niña, excluded the influence of the Pinatubo-cooled years in the early 90s, and then calculated the trends for each set. The graph really says it all, but his blog post provides all the analysis. The next El Niño looks as though it’s going to be interesting…
