#palaeoclimate — Public Fediverse posts

This fantastic interactive art piece from @bluerehn and Nellie Pease is on display at the South Australian Museum, or you can check it out online at https://chronovarium.com/.

Chronovarium encourages you to change boundary conditions, see how the landscape changes, and then 'collect' your core.

Here's mine - you can see the process from grassland to wooded area, to rainforest, to swamp, to jarrah forest, and the decisions I made along the way!

Brilliant work Emma, and thanks for making it available online 💚

This week's #NewBooks at the library:
- I adopted a damaged copy of David Farrier's Nature's Genius: Evolution's Lessons for a Changing Planet, published by @canongatebooks.

The other two are cases of the more I read, the more I go down rabbit holes.
- After reviewing Mysteries of the Deep, I bought an ex-library copy of the classic 1995 Paleoclimate and Evolution, with Emphasis on Human Origins, published by Yale University Press, to read more on the work of Elisabeth Vrba and colleagues (this one came from the holdings of the University Library of Durham)

- After reviewing Every Living Thing, I wanted to know more about Cuvier and tracked down an ex-library copy of the classic 1987 The Cuvier-Geoffroy Debate: French Biology in the Decades Before Darwin, published by Oxford University Press (this one came from the holdings of the University of Saint Katherine Library)

Coming back to this at #NCKF25 where my former boss (+IPCC lead author) Jens Hesselbjerg Christensen is looking at #Eemian #SeaLevelRise

Not quite as catastrophic as the MWP1a but still large. I wonder if this has been updated recently at all?

https://fediscience.org/@Ruth_Mottram/115304238980577506
Ruth_Mottram - This plot on wikipedia was made by @RARohde based on data published in late 90s and early 00s. Wondering if this has been updated or if there is new understanding on any of these palaeo records?

The first paper for our paper club is this recent one from McKay et al., presenting a thorough investigation of the (supposed?) 4.2 ka event. I'd read it when it was published, but just went through again in more detail, and what a good paper. Robust stats (of course, from this group), and they do a really nice job of building the case. I hope the group enjoys it!

🔴 🇦🇺 Highest ocean heat in four centuries places Great Barrier Reef in danger

“Climate model analysis confirms that human influence on the climate system is responsible for the rapid warming in recent decades. This attribution, together with the recent ocean temperature extremes, post-1900 warming trend and observed mass coral bleaching, shows that the existential threat to the GBR ecosystem from anthropogenic climate change is now realized.”

A full on but successful 4 days on the XFM beamline at the Ausgralian Synchrotron. We mixed things up this time by running some tree cores for Casey's PhD work - lots of cool features showing up! We also mapped a bunch of stalagmites, including some pilot data for my next job. 74 elemental maps made, a new record for us!

Box of rocks arrived for me today 😍 we will be taking these beauties to the Aus Synchrotron next month to get an idea if they might be suitable for #palaeofire research. Happily, these were collected by a friend of mine for her PhD, which means a potential collaboration with a friend (yay!), and the reuse of old samples rather than collecting new (double yay!).

I've said this a few times now, but, pending disaster, today is my last day of labwork for this postdoc! I've got 4 mm of sample to mill (40 samples!). This speleothem grew during the early Holocene before stopping, and starting again in the 1930s. I'm very excited to see the stable isotope data approaching this hiatus!

The listening entertainment for the day is the Hobbit, as read by Andy Serkis. Libraries are the best 💚

Cool new cave research out today in #Nature! Weij et al. find that in southern Australia glacial periods tend to be moist, contrary to the currently held view that glacial periods are cool and dry in the subtropics.

Neat work from Rieneke and a bunch of Aussie quaternarists!

(6/6) And it's not just what some fellow palaeobotanists like to call "flimflam" and too often is: doing #palaeoclimate reconstructions based on fossil taxon lists published ages ago and never verified.

To get results standing for a decade, you need the people who actually looked at all those fossils.

And #fossil #pollen are just beauts under the SEM.

random thought about Permian and Triassic climates: To me, the huge ocean Panthalassa seems like a good recipe for huge atmospheric rivers: it was huge, it had lots and lots of warm water, and in warm climate the air could take up a huge amount of water. (This is how I imagine the Carnian pluvials, for example.)

This map may look crude and slightly prone to giving you eye cancer, but it's my day's achievement 😅 In one of my final classes in #Palaeontology, students will compare the diversity of #fossil rodents across the #Holocene with #palaeoclimate data. Thanks to the biome reconstruction by Beyer et al. (2020) https://doi-org.proxy.library.uu.nl/10.1038/s41597-020-0552-1 they can generate their own palaeomaps of biomes that use the famed Biome4 model by Kaplan et al. (2003) https://github.com/jedokaplan/BIOME4/
Although the students aren't and don't have to be fluent in Fortran, Matlab or R, they have pieces of code that they can modify slightly to generate data and maps they need. And having to discuss data they generated on the spot makes their answers largely ChatGPT-proof.
