# HuffPo: ‘Global Warming Causes Volcanoes’

Huffington Post blogger DK Matai’s bio claims him to be “an engineer turned entrepreneur, investor and philanthropist with a keen interest in the well being of global society”.

If this guy is an engineer, then I’m Lady Gaga.

Did you ever notice that these warming alarmists have a habit of just making stuff up?

In a weekend post titled Are Global Warming, Volcanoes and Earthquakes Linked?, Mr. Matai exposes a less-than-thorough comprehension of earth science and basic engineering principles.

Ice is heavy and exerts enormous pressure on whatever lies beneath it. Under the ice’s weight, the Earth’s crust bends and as the ice melts the crust bounces up again. Imagine a floating cork, topped with a piece of lead. Will it not pop upwards when the lead is taken off? Similarly, a shrinking ice cap reduces the pressure on the earth’s mantle, causing it to melt and creating magma. Also, this frees tectonic plates up to move against each other and cause the friction needed to initiate earthquakes. This tallies with mathematical models that suggest such processes may potentially lead to more earthquakes, tsunamis and volcanic eruptions.

The cork illustration is way off. Each plate of the earth’s crust covers a significant fraction of the globe, not at all like a bobbing cork. Oceanic crust is 5 to 10 kilometers thick, while glacial ice might be a few hundred meters. And the average density of the crust is 2.7 times the density of ice. The mass of a glacier is not significant relative to the mass of the plate on which it rides.

It is true that ice load can deform the crust, and when that load is removed, the crust will rebound. Most of Michigan, for example, is still rebounding from the retreat of the ice cap (N.B. not a glacier) at the end of the last ice age some 12,000 years ago.

Get that? Still rebounding. So no, the crust doesn’t bob like a cork.

And melting ice doesn’t create magma. I’ll leave that explanation to Steven Goddard at wattsupwiththat.com. Suffice it to say that a reduced overburden of a thick ice layer might effect the melting point of underlying magma by half a degree C or so (out of +/-1,500 deg C). Really insignificant.

A thaw of ice caps caused by global warming may trigger more volcanic eruptions in coming decades by removing a vast weight and freeing magma from deep below ground, research suggests.

Research suggests“?! What research? Do you have a cite?

Iceland sits astride a mid-ocean ridge, the site of seafloor spreading and the engine that drives North America and Europe two centimeters further apart every year. Iceland is unusual in that it’s above sea level. If you wait around long enough, you’re going to see magma at the surface, glaciers or no.

Back to the original passage: “This tallies with mathematical models…[etc.]“. Again, what mathematical models? Can you produce or cite just one?

All this talk about earthquakes and volcanoes being the result of Global Warming does raise an interesting question. If, as Mr. Matai would have it, warming caused earthquakes and volcanoes at the end of the last ice age some 12,000 years ago, then that rules out volcanic CO2 as a cause of the end of the ice age.

That means increased atmospheric CO2 was a result, not a cause, of warming.

The PE license qualifies them to be experts in any other field that they choose, don’t you know… Sort of like a Ph.D., but better! (Written by a geologist who has worked many years with many licensed civil engineers!)

Vladimir, the plates are under pressure from both ends. One of the ends usually being driven under another plate. Mass isn’t even a significant factor. If you push a 2×4 against the wall, with a nickel resting on top of the 2×4, then have someone lift off the nickel, nothing will happen.
There are markings of glaciers all over the mountains in my area. They were not only so-called heavy, but also ‘rivers of ice’. They cut the mountainsides, but did not move them. Flaking, and freeze thaw, account for much more mountain mass removal than the actions of glaciers. These guys are a waste of time.

in an article by Alan Weisman. Weisman isn’t an engineer, either – his education was in literature – but he plays one for global warming.

The HuffPo blogger seems to have ripped his theory off almost verbatim.

But the pretense of scientific certainty has been blown out of the water by the recent scandals anyway – why fake data and graphs and suppress dissent and violate the law to keep it all secret if the facts are really on your side? So the target audience is the stupid and gullible (or, as we recently have come to know them, “Obama voters”), so like the bandits in Treasure of the Sierra Madre, they say, “Qualifications? We don’t need no stinkin’ qualifications!”

what is he doing writing for HuffPo? I know that the recession hit hard, but really…

Organized crime is well established in the climate industry having had years to get set up without interference. Unfortunately many people are unaware that recent climate ‘science’ claims do not hold up. The hockey stick creator even said in recent weeks that his claims have been given a clean bill of health and he was not disputed. A few people may be aware it was rigged to transfer trillions from evil US taxpayers to various crooks, and that carbon trading is made to order for organized crime. There is almost nothing about this whole thing including wind farms and solar panels that hasn’t been stolen or is about to be.

So it always has to be connections and corruption.

I love these idiots who “play engineer/climate expert on TV” who spout this nonsense– let ‘em keep speaking and making a fool of themselves, I say– as long as we are allowed to debunk them of course…….

Sounds like a normal day at Redsate. Does Sandler spend his down time lurking? HuffPo readers don’t sound as if they’re fully committed to the “science” either. Or was that just trolling?

Three words…………Chicago Climate Exchange. Did anyone see this on Glenn Beck’s show yesterday?
The so-called “brain” behind the CCX claims that the carbon credit industry will be a 10 Trillion dollar a year industry. Is it any wonder that the 5th largest owner of CCX is Al Gore and GOLDMAN SACHS employees??? And the “go-to” person for selling shares in CCX??? None other than Obama himself.
I wish I had a link to his show to explain how he laid it all out, but it’s obviously all about money and as long as they can scare the wits out of people to keep them subservient and make themselves rich, they will do everything they can to make it happen.

Lesson 1: The earth’s crust is anywhere from 20 to 30 miles thick, and is composed of solid rock.

Lesson #2: Solid Rock – depending on variety – can weigh anywhere from 160 – 190 pounds per cubic foot.

Lesson 3: Solid ice weighs about 57 – 58 pounds per cubic foot.

Lesson 4: Ergo, ice is lighter than rock.

Lesson 5: Conservatively, a square core of rock (1 ft x 1 ft x 20 miles thick) , at an average of 175 lbs / cu. ft. would weigh 18,480,000 pounds, or 9240 tons.

Lesson 6: Conversely, a square core of solid ice from a glacier 2,000 feet thick would weigh 114,000 pounds, or 57 tons – or a mere 0.617% of the 20-mile deep rock on which it sits. (Hardly the lead-on-cork scenario described in the theory.)

Lesson 7: In order for a glacier to weigh THE SAME as the rock on which it lies, the glacier would have to be about 61.4 miles thick.

Lesson 8: Solid lead weighs about 710 pounds per cubic foot; cork: about 15, for a ratio of 47.33 to 1. In order for a glacier to exert a comparable amount of pressure on the earth’s crust as the lead-on-cork premise, the glacier would have to be 2906 miles thick!

If the theory that the resulting reduction in weight that melting glaciers presents on the earth’s crust were true, why don’t we have similar seismic or subterranean “events” every time a large building is demolished? Or an avalanche cuts loose from a mountain side?
