We’re Doomed (Again)

This article from Science Blog suggests that “human-induced climate changes” will affect tectonic plate activity. In the excerpt below, the authors frantically suggest that we will be experiencing unprecedented plate movement as a result of the evils of men:

The erosion caused by rainfall directly affects the movement of continental plates beneath mountain ranges, says a University of Toronto geophysicist — the first time science has raised the possibility that human-induced climate change could affect the deep workings of the planet.

From that description, one might expect that Earth may soon experience alternating earthquakes and hurricanes as mankind continues to cause devastation to the planet.

The article continues with more about the professor conducting the computer models:

“In geology, we have this idea that erosion’s going to affect merely the surface,” says Russell Pysklywec, a professor of geology who creates computer models where he can control how a range of natural processes can create and modify mountains over millions of years. Pysklywec conducts field research in the Southern Alps of New Zealand, where the mountains are high and geologically “young.” He found that when mountains are exposed to New Zealand-type rainfall (which causes one centimetre of erosion per year) compared to southern California-type rainfall (which erodes one-tenth of a centimetre or less), it profoundly changes the behaviour of the tectonic plates beneath the mountains. “These are tiny, tiny changes on the surface, but integrating them over geologic time scales affects the roots of the mountains, as opposed to just the top of them,” says Pysklywec. “It goes right down to the mantle thermal engine — the thing that’s actually driving plate tectonics. It’s fairly surprising — it hasn’t been shown before.”

Wait! Did he say “geologic time scales?” You mean this is going to take some time?

“As a concept, imagine blanketing the European Alps with a huge network of ordinary garden sprinklers. The results suggest that the subtle surface weathering caused by the light watering have the potential to shift the tectonic plates, although you would have to keep the water on for several million years.”

At this rate, we’re doomed to destroy our planet just in time for the Sun to blow up.
