The Himalaya and Tibetan Plateau are only the most *recent* of the big mountain systems to have formed in south-central Asia. Well before India began to collide with Asia, the Gangdese Volcanic Arc had reached Andes-like proportions, standing ~3.5 km tall.

🚨 New paper alert! 🚨 The correlation between ENSO and Tropical Cyclone activity in the Pacific has strengthened in the recent decades. Meanwhile, there is a multidecadal oscillation in the ENSO-Atlantic TCs teleconnection strength. 🔗 dx.doi.org/10.1029/2025...

This is very good reading!

Congrats Georgina !

Congratulations @sfeakins.bsky.social on becoming the new Editor in Chief of Paleoceanography and Paleoclimatology, and thank you to Matthew Huber for all the years of service that did so much to strengthen this important journal!

Quick writeup about our recent paper on atmospheric rivers during the Last Interglacial in @eos.org! eos.org/editor-highl...

Nice analyses by Eden Markovitz and Nathan Steiger on recent persistent drought for Easter Island (Rapa Nui). Indeed, the island had one of the more severe future drying trends in our 2016 paper (Karnauskas et al. www.nature.com/articles/ncl...) agupubs.onlinelibrary.wiley.com/doi/10.1029/...

PNAS: Six-million-year-old ice discovered in Antarctica offers unprecedented window into a warmer Earth via our NSF COLDEX & US Antarctic Program. ❄️ www.pnas.org/doi/10.1073/...

This is cool, 6 million year old ice from Antartica with inferred temperature ~12°C warmer than the late Pleistocene. No CO2 level yet! (That will be highly anticipated!) www.pnas.org/doi/10.1073/...

An interesting paper exploring the early Neanderthal climate connection. This paper suggests that long-distance movement of Neanderthals would have been facilitated by periods of favorable climate. doi.org/10.1073/pnas...

Dr. Julie Edwards (@julieedtree.bsky.social) leads a new paper showing that high-resolution cellular-scale measurements (Quantitative Wood Anatomy) yield better temperature signals in Alaskan tree rings than even conventional MXD across all frequencies agupubs.onlinelibrary.wiley.com/doi/10.1029/...

⏰New paper⏰ Very excited to share our more recent paper published today in @nature.com Communications, where we show based on #clumped #isotope measurements in a giant sea #snail 🐚 that Europe experienced a monsoon-like climate during the #Eocene high-CO2 period. www.nature.com/articles/s41...

Our new study finds that the upper atmosphere is becoming more sheared and less stratified because of climate change. Both these changes are making the air less stable and more conducive to turbulence. Published in the November issue of Journal of the Atmospheric Sciences. doi.org/10.1175/JAS-...

#S42025 is grateful to all the instructors who took out time from their busy schedule and came to join us. Also not to forget who joined us online. Thanks for sharing your experience in the field.

Couldn’t have asked for a better talk @carbon8.bsky.social !

Day 2 starts with another great talk by Dr. Lijuan Sha on triple oxygen isotopes in speleothems and it’s applications #SEPM #S42025

Next we have Prof. Heather Stoll from ETH Zurich talking about marine- speleothem record connections

The late 1450s eruption (eruptions?) continues to be an odd one www.nature.com/articles/s43...

@jonbakerocean.bsky.social talking about this today in #S42025 - Amazing work and congratulations to the entire team !

Amazing such archives were preserved… Late Miocene Arctic warmth and terrestrial climate recorded by North Greenland speleothems www.nature.com/articles/s41...

New paper out on @natcomms.nature.com! We found recurring deep ocean oxygen minimum events in the Pacific Southern Ocean during Marine Isotope Stage 11, that are linked with perturbed Antarctic Bottom Water formation driven by West Antarctic Ice Sheet destabilization. www.nature.com/articles/s41...

Next we have Dr. Yassine Ait Brahim from UM6P talking about the speleothem based paleoclimate records in NW Africa #S42025 #SEPM

A great start to the Day 1 of #S42025 with Dr. Jon Baker from University of Innsbruck, Austria - talking about the Conventional Approaches in Speleothem Science #SEPM #S42025

Kicking off #S42025 officially.

🌊 Proxy data + models show the AMOC was shallow during the last ice age, similar to projections for future warming. Its depth is set mainly by AABW density. The Southern Ocean plays a key role in AMOC strength across climate states. www.nature.com/articles/s41...

Jay was on my PhD committee and taught me carbonate geochemistry, and to approach my speleothem problems with patience and depth. I’m deeply grateful for the time I got to learn from him. His influence will always remain a part of my journey. Will miss you, Jay!

Every ton of CO2 matters : @climatenerilie.bsky.social quantifies the climatic impacts of one large fossil fuel project and its implications for further human heat exposure or coral reef loss, and how committed emissions challenge climate pledges www.nature.com/articles/s44...

Paper alert 🎓🌿 I’m excited to share a new publication from my PhD On-site plant-wax biomarkers + compound-specific isotopes show why relying on bulk δ13C of SOM can mislead in the tropics. Case study: Jwalapuram (S. India). Read: www.cell.com/iscience/ful... Huge thanks to all co-authors 🙏

🌊 New study suggests climate change may supercharge ENSO into a stronger, more regular rhythm, syncing with other global climate patterns to trigger extreme, rapid swings in hydroclimate. Think climate “whiplash”, not just warming. www.nature.com/articles/s41...

Cool new Exp382 study out in @natcomms.nature.com showing an extreme poleward shift of ACC during the last interglacial. The coolest thing is that it confirms our 2024 results using fast and non-destructive XRF. 🤩 1) www.nature.com/articles/s41... 2) publications.iodp.org/proceedings/...

Cool work ! @iplumm.bsky.social !!

Your wonderful 206Pb/238U clock seems broken? Do not despair, you may be able to fix it using 207Pb/235U! Read here how…. 👇 kudos to Pieter and team, I certainly learned a lot in the process! 🤩😛 gchron.copernicus.org/articles/7/4... @annabelwolf.bsky.social @pucicu.de @geochron.bsky.social

New modelling study suggests the deglacial radiocarbon seesaw was driven by weaker Antarctic overturning + lower Southern Ocean reservoir age — not stronger circulation. Both poles had sluggish deep water flow. www.nature.com/articles/s41...
