Quick — tax the magma
It’s another round of Antarctic Doom about next to nothing. In April Antarctica’s ice was melting five times faster than usual. Now it’s losing ice three times faster in the last five years than the 15 before that! What you won’t hear is how the Antarctic ice cap has 29 million cubic kilometers of ice and has been there for 30 million, mostly warmer, years. You also won’t hear how Antarctica was warmer in Roman Times, or that the Antarctic Peninsula has cooled by almost 1 degree.
You also won’t hear a word about any volcanoes
The new paper has zero mentions of the word. But other scientists have published plenty of papers describing how the West Antarctic zone is being warmed from below by 1200 degrees of magma. According to scientist Dustin Schroeder and co, it is as if the Thwaites Glacier in West Antarctic is sitting on a “stovetop burner”. His words. Thwaites Glacier,, smack in the middle of the warming is being melted from below by geothermal heat. Then there is the large blob of superheated rock 60 miles below West Antarctica. The researchers use the phrase “like a blow-torch”…. Capping it off, only last year 91 new volcanoes were discovered 2km underneath the West Antarctic Rift. That’s new, as in, we didn’t know they were there.
Follow the reasoning, either a trace gas 10 kilometers up is causing some spots of Antarctica to warm and other parts to cool, or hot magma at 1,200C is. What’s more likely?
