Methane Madness
Richard Cronin:
Uuummm. Methane is produced both by Fischer-Tropsch reactions and Sabatier reactions within the Earth. As the Earth heats from within we produce more CO2, more methane, and more longer chain hydrocarbons (oil).
First Methane Leak Found on Antarctic Sea Floor Confirms Researchers' Fears
Tim adds:
More hysteria from the Gang Green. As if methane hasn't been leaking before now! Oh, and how do they square this with the fact that the oceans around Antarctica haven't really warmed as far as anyone can tell, that Antarctic ice is up, and that the whole freaking planet hasn't warmed? Does a fraction of a degree mean melting and methane release? What a ridiculous article.
Richard adds:
Your mention of Antarctic ice growing (thickening the sheets and buckling up into ridge systems) brings up another point.
There is snowfall around the perimeter of Antarctica but very little falls in the arid interior. Rather, the ice sheets form by steam vented from below. Antarctica is very seismically active. There are even mountain passes cut thru the Transantarctic mountain range and researchers describe "rivers of ice†flowing from East Antarctica into West Antarctica, where the greatest amount of calving occurs.
I reply:
Indeed Richard Cronin. I long argued that the calving in WAIS was a result of pressure from ice from EAIS, much like a fingernail breaks off after it grows too long (since WAIS floats on the sea.) As you say, there is virtually no precipitation in Antarctica thanks to the bitter cold, so ice builds up through geothermal processes. Oh, and that "warmest day ever" off the coast of the Antarctic Peninsula was clearly a result of undersea volcanism offshore. I read a paper about that recently, although I doubt I could find it again unless I had to (Google loves to hide that kind of thing.)
