Remember the hysterics over the Antarctic ice shelves melting?

Antarctic ice shelves not melting at all, new field data show

Crafty boffins got elephant seals to survey for them

Twenty-year-old models which have suggested serious ice loss in the eastern Antarctic have been compared with reality for the first time - and found to be wrong, so much so that it now appears that no ice is being lost at all.

"Previous ocean models ... have predicted temperatures and melt rates that are too high, suggesting a significant mass loss in this region that is actually not taking place," says Tore Hattermann of the Norwegian Polar Institute, member of a team which has obtained two years' worth of direct measurements below the massive Fimbul Ice Shelf in eastern Antarctica - the first ever to be taken.

According to a statement from the American Geophysical Union, announcing the new research:

It turns out that past studies, which were based on computer models without any direct data for comparison or guidance, overestimate the water temperatures and extent of melting beneath the Fimbul Ice Shelf. This has led to the misconception, Hattermann said, that the ice shelf is losing mass at a faster rate than it is gaining mass, leading to an overall loss of mass.

The team’s results show that water temperatures are far lower than computer models predicted ...

Hatterman and his colleagues, using 12 tons of hot-water drilling equipment, bored three holes more than 200m deep through the Fimbul Shelf, which spans an area roughly twice the size of New Jersey. The location of each hole was cunningly chosen so that the various pathways by which water moves beneath the ice shelf could be observed, and instruments were lowered down.

The boffins also supplemented their data craftily by harvesting info from a biology project, the Marine Mammal Exploration of the Oceans Pole to Pole (MEOP) effort, which had seen sensor packages attached to elephant seals.

"Nobody was expecting that the MEOP seals from Bouvetoya would swim straight to the Antarctic and stay along the Fimbul Ice Shelf for the entire winter," Hattermann says. "But this behaviour certainly provided an impressive and unique data set."

Normally, getting sea temperature readings along the shelf in winter would be dangerous if not impossible due to shifting pack ice - but the seals were perfectly at home among the grinding floes.

Overall, according to the team, their field data shows "steady state mass balance" on the eastern Antarctic coasts - ie, that no ice is being lost from the massive shelves there. The research is published in the journal Geophysical Research Letters.

This is good news indeed, as some had thought that huge amounts of ice were melting from the region, which might mean accelerated rates of sea level rise in future.

I for one would like SEE these ' 20 year old models', please.

This underscores what I've always found baffling about a large majority of climate science: computer models.

Time and time again, these models are proven wrong. Often times these models provide data on laughable subject matter - i.e. "we know what the weather was like on this day 400,000 years ago." Much of this stuff, if not dubious, is at best a guess from a computer.

Yet we are supposed to take it all as empirical gospel and enact sweeping taxes and regulation that are poised to cripple economies. All on stuff that is spit out of a computer model.

I write software for a living. I know how error prone this stuff is.

James Lovelock at 92 years of age has some interesting comments on his old therioes about global warming/ climate change.

His other comments are also going to drive the green power people crazy. Wind power is a waste of time, nuclear is the way to provide power needs and fracking to obtain oil. gas is better than mining for coal,,,

The godfather of global warming lowers the boom on climate change hysteria

By Lorrie Goldstein ,Toronto Sun

Two months ago, James Lovelock, the godfather of global warming, gave a startling interview to msnbc.com in which he acknowledged he had been unduly “alarmist” about climate change.

The implications were extraordinary.

Lovelock is a world-renowned scientist and environmentalist whose Gaia theory — that the Earth operates as a single, living organism — has had a profound impact on the development of global warming theory.

Unlike many “environmentalists,” who have degrees in political science, Lovelock, until his recent retirement at age 92, was a much-honoured working scientist and academic.

His inventions have been used by NASA, among many other scientific organizations.

Lovelock’s invention of the electron capture detector in 1957 first enabled scientists to measure CFCs (chlorofluorocarbons) and other pollutants in the atmosphere, leading, in many ways, to the birth of the modern environmental movement.

Having observed that global temperatures since the turn of the millennium have not gone up in the way computer-based climate models predicted, Lovelock acknowledged, “the problem is we don’t know what the climate is doing. We thought we knew 20 years ago.” Now, Lovelock has given a follow-up interview to the UK’s Guardian newspaper in which he delivers more bombshells sure to anger the global green movement, which for years worshipped his Gaia theory and apocalyptic predictions that billions would die from man-made climate change by the end of this century.

Lovelock still believes anthropogenic global warming is occurring and that mankind must lower its greenhouse gas emissions, but says it’s now clear the doomsday predictions, including his own (and Al Gore’s) were incorrect.

He responds to attacks on his revised views by noting that, unlike many climate scientists who fear a loss of government funding if they admit error, as a freelance scientist, he’s never been afraid to revise his theories in the face of new evidence. Indeed, that’s how science advances.

Among his observations to the Guardian:

(1) A long-time supporter of nuclear power as a way to lower greenhouse gas emissions, which has made him unpopular with environmentalists, Lovelock has now come out in favour of natural gas fracking (which environmentalists also oppose), as a low-polluting alternative to coal.

As Lovelock observes, “Gas is almost a give-away in the U.S. at the moment. They’ve gone for fracking in a big way. This is what makes me very cross with the greens for trying to knock it … Let’s be pragmatic and sensible and get Britain to switch everything to methane. We should be going mad on it.” (Kandeh Yumkella, co-head of a major United Nations program on sustainable energy, made similar arguments last week at a UN environmental conference in Rio de Janeiro, advocating the development of conventional and unconventional natural gas resources as a way to reduce deforestation and save millions of lives in the Third World.)

(2) Lovelock blasted greens for treating global warming like a religion.

“It just so happens that the green religion is now taking over from the Christian religion,” Lovelock observed. “I don’t think people have noticed that, but it’s got all the sort of terms that religions use … The greens use guilt. That just shows how religious greens are. You can’t win people round by saying they are guilty for putting (carbon dioxide) in the air.”

(3) Lovelock mocks the idea modern economies can be powered by wind turbines.

As he puts it, “so-called ‘sustainable development’ … is meaningless drivel … We rushed into renewable energy without any thought. The schemes are largely hopelessly inefficient and unpleasant. I personally can’t stand windmills at any price.”

(4) Finally, about claims “the science is settled” on global warming: “One thing that being a scientist has taught me is that you can never be certain about anything. You never know the truth. You can only approach it and hope to get a bit nearer to it each time. You iterate towards the truth. You don’t know it.”

Is it getting hot in here ? I do sense something rising, that's for sure.
