Been thinking about student writing assignments and how to describe what AI-soup-speak sounds like.

My take now is, that if a piece of writing sounds like a horoscope reading or prediction, it's written by generative AI

It's been a good few months of getting some fieldwork in. There's lots of Holocene muds and sands in WA, NSW, and VIC that still have many secrets to tell about past coastal change.

I have some wonderful colleagues I get to work with along on the way! : )

Global sea-level rise in the early Holocene revealed from North Sea peats - Nature An early Holocene sea-level curve based on data from the North Sea reveals two phases of accelerated sea-level rise owing to meltwater from the North American and Antarctic ice sheets.

Global sea-level rise recorded in North Sea peats! Paleo sea-level work hitting it big.

Join @ruthreef.bsky.social @kerryleerogers.bsky.social Catherine Lovelock and me at the Australian Marine Science Assoc. conference in Narrm for our session 'Sea-level rise and coastal change through time and space' !

Submit your abstract by 14th Feb : )

Conditions like these are not ideal for grant writing....!!

(Plz send me good vibes for getting my DECRA application together)

Great few days learning the ways of the uwitech corer at Lake Bullen Merri for Louisa Sheridan's PhD. The western volcanic plain is such a fabulous part of Victoria!

Great job opportunity here as part of @21stcenturyweather.bsky.social to work on changes in storms under climate change! jobs.unimelb.edu.au/en/job/91911...

We are hiring! Full details at the link below. We are looking for 2 postdocs to work on reconstructing past sea surface temperatures and sea ice distributions as part of the "Past 2 Future" consortium seeking to improve climate models with palaeoclimate data durham.taleo.net/careersectio...

🔥New paper alert! 🔥 Jacky Austermann and I show that simultaneous Antarctic collapse + Laurentide persistence during the Last Interglacial (130,000 - 115,000 years ago) could explain the local sea level oscillation observed in the Bahamas, Seychelles, Australia, and elsewhere. tinyurl.com/yjj7w2mr 🧵

neat sediment records to help us understand past environmental change in an under-studied area! super excited to see what's in em 👀

Truly appalling decision. My fear is that other governments will see it as a great idea. Science does not, and cannot, operate in a vacuum. Almost all the impact comes from collaboration with non-scientists.

It’s not ok that many people are confusing a policy goal (1.5 C) with a physical limit of the climate system. It threatens rash actions, it threatens despair, and it threatens loss of credibility.

PALSEA friends we have a session we'd love to see your abstracts in... 'understanding drivers of paleo sea level change through proxies and modeling'

Deadline extended for abstract submission to the 2025 PAGES OSM! It's looking like a great meeting, with 600+ abstracts so far.

For all my Common Era friends, we've got a 2k session which is looking great so far but would also love YOUR amazing science.

That's great Emma!! Let the migration begin!

Landscape burning facilitated Aboriginal migration into Lutruwita/Tasmania 41,600 years ago Paleoecological records show that Aboriginal people burned wet forest to first settle in Tasmania 41,600 years ago.

Our new study out in @ScienceAdvances shows human presence in Tasmania at least 41,600 years ago, nearly 2000 years earlier than previously thought, and Aboriginal people burned and used wet forests.

PaleoSTeHM v1.0-rc: a modern, scalable spatio-temporal hierarchical modeling framework for paleo-environmental data Abstract. Geological records of past environmental change provide crucial information for assessing long-term climate variability, non-stationarity, and nonlinearities. However, reconstructing spatio-...

How about AOGS in 2024?!

We've got a session in Ocean Sciences:

'Past, present, and future sea-level change in Asia, Oceania, and beyond'

See you in South Korea!

Hello AGU-ers!

We're doing a PALSEA working group meet up on Monday 11th December at Zeitgeist bar from 7 pm.

Everyone is welcome - see you there!

Cute pet names like LEO189-190, lol

When your job is mud kitchen !

Ancient warning of a rising sea Fossil coral reefs in the islands of the Seychelles may indicate where sea level rise will be felt the hardest as human-caused climate change impacts the world’s oceans.

@drandreadutton.bsky.social The Washington Post ran a huge interactive piece on your work about how fossil corals let us understand past sea level rise.

we have a new pre-print out reviewing wind-blown dunes. we explain why dunes look the way they do, and classify them. lots of thought, debate, and time went into this one - hopefully you find it useful! eartharxiv.org/repository/v...
