The breakup of the supercontinent Gondwana set off a chain of tectonic events that eventually uplifted parts of East Antarctica, creating the perfect conditions for the formation of an ice sheet, a new study suggests. eos.org/articles/the...

Fascinating piece in The Conversation by @gernon.bsky.social discussing recent work by him and his colleagues investigating how continental breakup and consequent mantle dynamics may have primed the topography of Antarctica for glaciation ~34 million years ago. theconversation.com/why-antarcti...

Our new study on how uplifting terrain in Antarctica helped provoke glaciation is out @science.org. Delighted to see this work through after many years. www.science.org/doi/10.1126/... @sasbrune.bsky.social @gfz.bsky.social @derekkeir.bsky.social @polarguy.bsky.social @unisouthampton.bsky.social

The formation of the East Antarctic Ice Sheet has stumped scientists. Could a tectonic event that took place tens of millions of years prior offer an explanation? eos.org/articles/the...

My latest for @science.org: The rifting of Gondwana likely led, some *100 million* years later, to the formation of the Antarctic Ice Sheet. (Yes, CO2 decline was also part of it.) The past isn't even past. A fascinating expansion of @gernon.bsky.social's mantle waves work.
