Wind and waves scatter sea ice, not AGW

Antarctic sea ice

Antarctic sea ice can be breathtaking.

Waves  chase away warming

A paper has arrived from NIWA that says, in effect, warming is not necessary to explain the disappearance of much sea ice. That it removes a warming element from the polar pieces of the global warming puzzle gives me great pleasure. Well done, them!

I’m talking about “Storm-induced sea-ice breakup and the implications for ice extent” (Nature 509, 604–7), published online in Nature on 29 May, by A.L. Kohout, M.J. Williams, S.M. Dean and M.H. Meylan (KWDM). Its major discovery is that large waves travel much farther through pack ice than hitherto realised, thus breaking up much more ice than we realised and allowing it to be swept away by wind and wave—it hasn’t been melting from the heat of global warming.

Egos on ice

If you have been following the story of the Akademik Shokalskiy, you’ll know it’s a global warming boat stuck in an Antarctic ice pack. What piqued my curiosity was that the expedition is called ‘Australasian’. Now, I don’t mind when Aussies make absolute fools of themselves, but when Kiwis are involved in the foolishness, I get brassed off. More so when the stupidity is funded by my taxes.

Antarctic ice expands “against odds”

From a scientist friend, who comments:

About two weeks after it was noised on various blogs and electronic news sources, and is old “news”, The Australian finally deigns to notice the record Antarctic sea-ice (I wonder whether the SMH and The Age will now me-too the story as well?). Leaving aside the wonderful headline, the article itself is a classic attempt to weasel out of accepting the obvious conclusion. The scientists involved really ARE shameless.

I entirely agree with him. This story presents a deplorable mish-mash of propaganda from a scientist who should be a lot better behaved. Be nice to see this covered in the Herald – or has it been – anyone know?

Please note the frank distortion in the original headline: the sea ice hasn’t expanded “against the odds”, it has simply defied certain (wrong!) predictions. Emphasis added, my comments in green. – RT

ANTARCTIC sea ice has expanded to cover the largest area recorded since satellite mapping began more than three decades ago, in stark contrast to this year’s record melt on the northern pole.

The expansion continues a trend of increasing Antarctic sea ice cover of about 1 per cent a decade and is at odds with predictions of climate change models that continue to forecast a long-term decline. Continue Reading →

Renowden’s foot again finds his mouth

Renowden continually misquotes me.

I wrote about the summer low achieved by Arctic sea ice. He maligns me for saying the ice didn’t melt until winds pushed it away into warmer water.

Gareth, criticise me for giving voice to heresy; and by all means, fault my scholarship, my knowledge of climatic or arctic affairs; feel free to mock my “disconnection from reality”; I hope you even pull out a paper by Notz and Marotzke and share the authors’ speculation that, as is apparently obvious to the rest of you, “the most likely explanation for the linear trend [in sea ice decline] during the satellite era from 1979 onwards is the almost linear increase in CO2 concentration during that period.”

But I didn’t say it. NASA did.

So now please kindly redirect all that rude, inaccurate mockery to the proper quarter.

UPDATE 30 SEP

Renowden’s friend Rob Taylor, in comments below, cites one John Yackel in Science Daily. Yackel makes a couple of howlers.

First, he contradicts NASA and insists on talking about the summer Arctic ice “melt”. Obviously he didn’t get NASA’s memo explaining about the storm that shifted the sea ice before it melted.

Second, he asserts that, with the ice gone and the sea surface exposed to the air, “more moisture off the ocean’s surface” will “get into the atmosphere”, making for more violent storms.

Remarkable. Here’s a geographer who doesn’t know that the amount of water vapour in the air depends on the temperature. I learnt that in high school but somehow he missed it at university.

But he also apparently imagines that “the water vapor in the atmosphere makes for more violent storms” – it doesn’t need a higher temperature at all! Well, it’s a new concept, but I’m not sure how it works.

I think it’s nonsense.

Finally, I observe that Rob Taylor claims I’m wrong about something, but none of our friends from the dark side deny that Renowden disagrees with NASA. Renowden is wrong to call this record ice disappearance a “melt” and blame it on global warming and therefore on our considerable, unforgivable sins.

Arctic sea ice dispersed by storm – not hot air

NASA admission

Arctic cyclone in August ‘wreaked havoc’ on sea ice

via NASA finally admits Arctic cyclone in August ‘broke up’ and ‘wreaked havoc’ on sea ice — Reuters reports Arctic storm played ‘key role’ in ice reduction | Climate Depot.

NASA has announced that an Arctic storm played a ‘key role’ in a dramatic new summer minimum ice extent recorded in August.

Reuters news service filed a September 21 report based on NASA’s video admission titled: “NASA says Arctic cyclone played ‘key role’ in record ice melt.” The news segment details how the Arctic sea ice was reduced due to “a powerful cyclone that scientists say ‘wreaked havoc’ on ice cover during the month of August.” (Reuters on “Arctic Cyclone” — 0:47 second long segment — Rob Muir reporting.)

Why does everyone feel guilty about the disappearance of the Arctic ice? All it proves is a bit of warming; it most certainly does not prove a human cause for that warming. Continue Reading →

Lawless misled by the clueless

Lucy Lawless, famous actress and newly-minted Greenpeace activist, claimed yesterday:

“…make no mistake, due to the harshness and remoteness of the Arctic environment, an oil spill up there will make the Gulf of Mexico look like a children’s party.”

I agree that it’s a distinct possibility, and precautions should be taken to prevent and, at need, to clean up such a spill. No doubt about it. But then our eco-warrior says boldly:

“To see the melting of the sea ice not as a warning to humanity but as an invitation to drill for more of the stuff that caused the problem in the first place is the definition of madness. What Shell is doing is climate change-profiteering.” (Emphasis added. H/T Richard Cumming)

Lucy, turn towards your Greenpeace advisers and say after me: “What is the evidence?” Continue Reading →

Multiple meltings of Arctic sea ice

The Skate at North Pole in 1959

Australis posted this link to Steven Goddard’s Real Science list of newspaper articles for us here in comments. I highly recommend it.

Whenever anyone – anyone at all – becomes anxious over apparently excessive melting of Arctic sea ice, this long list of previous such meltings will demonstrate that Nature can cope with it and bounce back from it.

Whenever anyone tries to alarm others with the modern, allegedly excessive, melting of Arctic sea ice, this long list of historical events will stop them in their tracks and prevent alarm.

It’s what we might call proof that modern sea ice melting is not unprecedented, despite the efforts made by the likes of Greenpeace to make us believe that it is.

Speaking of Greenpeace

For example, in August 2009, Greenpeace were caught in a lie. Continue Reading →

More ice in scary melting

Arctic ice

The Associated Press chills our blood again with a story on record Arctic sea ice melting.

Arctic sea ice melted this summer to the second lowest level since record-keeping began more than 50 years ago, scientists reported Thursday, mostly blaming global warming.

“This is not a random event,” said oceanographer James Overland of the U.S. National Oceanic and Atmospheric Administration. “It’s a long-term change in Arctic climate.”

Only in 2007 was there less summer sea ice, which has been dramatically declining since scientists began using satellites to monitor melt in 1979.

So, unless I’m mistaken, in each of the last four years there has been more ice than there was in 2007. That sounds like a recovery — it’s certainly not getting worse. Continue Reading →

Taking the chill off the Arctic

burning ice

What a joke, doctor

At the Huffington Post, “field biologist” Dr Reese Halter talks of the “unprecedented warming of our globe” and claims that “missing” Arctic sea ice is a “wake-up call.” He says the news of Arctic sea ice reaching its lowest point since the start of satellite observations in 1972 (actually 1979) is “outright heartbreaking.”

The heartbroken biologist meanders through observations on the climate, economics and some waffling, brainlessly misleading arguments against climatic scepticism. Continue Reading →

Cool that ice nonsense

Arctic ice

Georg Heygster, head of the Physical Analysis of Remote Sensing Images unit at the University of Bremen’s Institute of Environmental Physics, announces a new record Arctic ice minimum today.

Ignoring the fact that they actually report 140,000 square kilometres more ice today than in 2007 (the previous record minimum) because of altered methods, the good Georg raises more questions than he answers. Like any good climate scientist. First (though this could be the AFP reporter):

Arctic ice cover plays a critical role in regulating Earth’s climate by reflecting sunlight and keeping the polar region cool.

QUESTION: At the last minimum, in 2007, how much did global temperature rise due to the reduced ice cover? ANSWER: Global temps did not rise in 2007 — they fell about 0.4°C. Any albedo effect reducing global temperatures is likely to be insignificant. Continue Reading →

The dirt on Black Carbon

village fires

How convenient this is! With all the doubt now falling on the culpability of carbon dioxide (“carbon”) in the crime of global warming, the worried warmists have wheeled in a new culprit accused, already chained and bearing a conspicuously disreputable name — Black Carbon.

Just as CO2 has been wilting under an intensive examination and showing undisputable signs of innocence, how lucky to have soot standing by to shoulder the blame on behalf of we horrid humans. Continue Reading →

Revkin declines Joe Romm’s bet on Arctic sea ice

Andrew Revkin

Andrew Revkin – Dr Who?

Warmist internecine strife has never really appeared on my radar, but now it’s actually spoiling the image. How encouraging it is to my sceptical heart to hear leading warmists brawling in their little playground. They express perfect hatred for each other.

Are they frustrated that their warmist preferences for scientific conclusions and policy recommendations are becoming as last season’s fashions? Does it sting their vanity that they can do nothing to halt the loss of face that now disfigures their darling beliefs in global warming?

Does the sudden, inexorable and widespread use of the terms “scam”, “myths” and “fallacies” associated with “climate change” drive them insane with rage? We can but hope. Continue Reading →

Global warming first: oxygen involved!

The mighty Merz Glacier

A story in the NZ Herald a few days ago talked about giant Antarctic icebergs:

A massive iceberg struck Antarctica, dislodging another giant block of ice from a glacier, Australian and French scientists said.

The end of the mighty Mertz Glacier had been repeatedly hammered by the 97-kilometre-long iceberg as it moved in the ocean currents. Note that there’s no mention of global warming to explain this “breakup” of ice.

This event was driven entirely by mechanical forces …

… until the final paragraph, when the article talks about oxygen levels and quotes “a leading climate expert”, Steve Rintoul:

Oxygen levels being fed into the world’s ocean currents are now changing “and the overturning circulation currents will respond to that change,” Rintoul said. Observing what happens “will … allow us to improve predictions of future climate change.”

One wonders whether Rintoul is accurately quoted.

It is understandable that the overturning circulation might transport water of differing oxygen levels around the oceans, but it is incredible that differing oxygen levels might affect the overturning circulation.

I do not understand how observing the effects of oxygen on the overturning circulation might have any effect on our predictions of “climate change”, much less allow us to improve them.

Further explanation is required, and it ought to have been obtained by our beloved Herald before publication of this nonsense.
