“Scientists Locate Apparent Hydrothermal Vents off Antarctica“. Anthony Watts reprints this interesting Columbia University report so he can imply that this discovery somehow explains why the Antarctic is losing ice mass. It’s not man-made after-all! Whew.
Hydrothermal vents occur at tectonic plate boundaries. There aren’t any such zones underneath or along the coasts of Antarctica. Even if there are hydrothermal vents where Anthony wants them, such vents are oceanographically speaking insignificant point sources of heat. Go back to the wishful thinking/goofy idea cupboard and try again.
