This article is bizarre.
Some quotes that strikes me as just really really odd:
"Jerry Mitrovica has been overturning accepted wisdom for decades" - no one is this good.
"What he calls postmodern geology" - this is very concerning. Postmodernism is like Foucault and Derrida and about power and society. Foucault is actually the most cited academic of all time statistically, so for a Professor to knowingly use this word to describe the science of geology is just strange.
"Though a practiced public speaker" - what is this? should he be ashamed?
"These are known as sea-level fingerprints, because each ice sheet has its own geometry. Greenland produces one geometry of sea level change and the Antarctic has its own. Mountain glaciers have their own fingerprint." - what?
