I am a climate scientist, focused on paleoclimate, sea level change and the evolution of Quaternary glaciations.
I reconstruct ice sheets using glacial isostatic adjustment and ice sheet modelling. In Japan but have been all over the place. 🇨🇦🇯🇵🇦🇺🇩🇪🇸🇪

It is not the right platform to do that, though. Musk controls what people see, and he purposely uses it to spread misinformation as he sees fit. It is a waste of time.
From my view, it is much more useful to be on a platform where people are willing to listen. That platform, IMO, is Mastodon.

I left the day Musk bought it. You can't educate people who are there to dominate at any cost. Why sacrifice your mental health to argue with trolls? There is nothing to be gained.

I had a lot of troubles with this, but I always remember my meeting with Larry Edwards (one of the top speleothem researchers). After grilling me a bit, he encouraged me and said that taking my own path was the only way forward.

I have stepped on some toes that definitely have made some researchers unhappy, but it is the only way to advance things.

Most of these countries are experiencing freezes or cuts to funding.
Back in 2009 when my mining industry job was cut, my boss said "it might be time to get a PHD". In 2025, the advice might be "it might be time to go into industry".

I was having a look at this a few days ago. I am definitely excited about the results!

What do you mean? Heninngsmoen's name appears in the subhead.

Vestfold is an area in southern Norway where sea level is falling as a result of glacial isostatic adjustment. 10,000 years ago, sea level was over 60 m higher than now!

Another poster yesterday pointed out this is clearly AI generated. Look at the faces of the people.

I have seen far too many garbage papers published there to trust anything.

Even just looking at the fold, where layers just suddenly end. That is not how geology works.

Yikes, the southern fire is not far from where the University of Manitoba does their geology field course. I hope they have wrapped it up already.

Unfortunately I do not arrive until Wednesday morning, but I am sure we can run into each other at some point.

I was talking to my dad this morning, who farms in Manitoba. It is not just the extreme heat, but the strong winds that are accompanying the heat that is affecting things. It is very dry and there are fire bans.

My presentation is on Friday morning in the Paleoclimate session!

It is amazing that this is the first time that the rupture from an earthquake has been filmed.

Are you planning to do volcano hunting in Kyushu?

Obviously, pin-pointing a specific sea level from these data is difficult, since the height of the sill likely varied due to tectonics, and the "connection" based on these proxies probably does not depend precisely on sea level being above or below -60 m.

During MIS 5, there is also fluctuations, with evidence of isolation during the MIS 5b stadial. During MIS 3, there is evidence that sea level must have risen enough that there was periodically a connection with the Mediterranean Sea (i.e. sea level > -60 m).

The major interglacials of MIS 17, 13, 11 and 9 indicate fully connected conditions. MIS 7 shows fluctuations, indicating that ice volume varied. This is perhaps not surprising, since there is a large interruption in MIS 7 with a sharp rise in δ¹⁸O in the marine records, likely a brief glaciation.

During glacial periods, sea level fell sufficiently to isolate the Gulf of Corinth from the Mediterranean Sea. Therefore, this record can be used as a way to estimate global ice volume. The major glacial periods of MIS 18, 14, 8, 6, 4 and 2 show a complete isolation of the Gulf.

They conclude based on ¹⁴C, they conclude the mountain was covered for at least 20-25 thousand years during the LGM. The inheritance signature of cosmogenic ²⁶Al and ¹⁰Be indicates a substantial erosional event during the penultimate glacial cycle.
