Connecting the Atlantic Meridional Overturning Circulation to the Southern Ocean Following the Closure of Equatorial Seaways During the Cenozoic
Before the Miocene, the Atlantic overturning circulation was confined to the Northern Hemisphere, becoming inter-hemispheric thereafter During the Cenozoic, the upwelling of North Atlantic Deep W...

Devastating news that marine biologist, science communicator, and UniMelb VC Professor Emma Johnston has died after a short illness.
She really was an extraordinary and visionary leader, and I have no doubt she would have made a fine Chief Scientist one day.

Emma Johnston was a visionary scientist, environmentalist and leader, with an abiding hope for humanity
The University of Melbourne Vice-Chancellor, who has died aged 52, was driven by a deep love of science and a desire to safeguard the planet’s future.

Really grateful to be reconnecting w colleagues.
Feels like a subdued AGU this year esp in the paleo sections.
Registrations are down by about a third v last year.

I was shocked when I first saw these results from standard climate models used in IPCC reports: for high emissions, the Atlantic overturning circulation #AMOC shuts down in all 9 models that ran past 2100, and is well on the way to shutdown by 2100.
