Time Magazine writes what might possibly be the stupidest article about climate ever – climate change causes volcanoes

Anthony Watt:

The stupid, it burns like a magnesium flare.

Excerpt from the article:

Now, you can add yet another problem to the climate change hit list: volcanoes. That’s the word from a new study conducted in Iceland and accepted for publication in Geophysical Research Letters. The finding is bad news not just for one comparatively remote part of the world, but for everywhere.

Iceland has always been a natural lab for studying climate change. It may be spared some of the punishment hot, dry places like the American southwest get, but when it comes to glacier melt, few places are hit harder. About 10% of the island nation’s surface area is covered by about 300 different glaciers—and they’re losing an estimated 11 billion tons of ice per year. Not only is that damaging Icelandic habitats and contributing to the global rise in sea levels, it is also—oddly—causing the entire island to rise. And that’s where the trouble begins.

Riiight.

Here’s the money quote:

“As the glaciers melt, the pressure on the underlying rocks decreases,” Compton said in an e-mail to TIME. “Rocks at very high temperatures may stay in their solid phase if the pressure is high enough. As you reduce the pressure, you effectively lower the melting temperature.” The result is a softer, more molten subsurface, which increases the amount of eruptive material lying around and makes it easier for more deeply buried magma chambers to escape their confinement and blow the whole mess through the surface.

“High heat content at lower pressure creates an environment prone to melting these rising mantle rocks, which provides magma to the volcanic systems,” says Arizona geoscientist Richard Bennett, another co-author.

Perhaps anticipating the climate change deniers’ uncanny ability to put two and two together and come up with five, the researchers took pains to point out that no, it’s not the very fact that Icelandic ice sits above hot magma deposits that’s causing the glacial melting. The magma’s always been there; it’s the rising global temperature that’s new. At best, only 5% of the accelerated melting is geological in origin.

So, Iceland has had melting glaciers, OK we’ll accept that, but Iceland is not the world, and a good number of volcanoes that have erupted in the last century are in the tropical parts of the world where there are no glaciers on the volcanoes or magma fields, yet somehow, this writer, Jeffrey Kluger, extrapolates Iceland’s glacier melt to volcano link up to to the entire world.

To the uniniformed (such as Time Magazine writers), graphs like this one might seem to be “proof” of such Icelandic-to-global extrapolation:

Gosh, it sure looks like another slam dunk for carbon dioxide driven climate hell in a handbasket, doesn’t it? The VEI starts increasing right about the time of the industrial revolution.

For those unfamiliar: The volcanic explosivity index (VEI) was devised by Chris Newhall of the US Geological Survey and Stephen Self at the University of Hawaii in 1982 to provide a relative measure of the explosiveness of volcanic eruptions. (Wikipedia)

But, there’s a hitch, according to NOAA data, volcanic activity worldwide actually went DOWN in the 2000’s while the climate changing carbon dioxide went UP in global concentration:

Correlation isn’t causation, at least when it comes to CO2 and climate and volcanoes.

Something that DID increase during the study period was the Atlantic Multi-decadal Oscillation (AMO). Guess where Iceland is? In the North Atlantic, which has been in the warm phase since about 1980.
