Today, we published a study long in the making on how upper and subsurface tropical Pacific waters responded (and maybe will adjust) to warmer global climate. Here’s the story of how we got here after 15 years. many authors but shout out @jfarmersalmanac.bsky.social 🌊 www.science.org/doi/10.1126/...

Excited !!!

🚨New work🚨 led by Ph.D. student Dipesh Chuphal (IIT Gandhinagar), shows that the recent drying of the Ganga River basin is unprecedented in 1,300 years—more severe than historical famines. This ~multidecadal drying appears forced, but many models do not capture it. ☔️ 🌧️ www.pnas.org/doi/10.1073/...

After a brief (ahem) hiatus, the HadCRUT5 global temperature dataset has now been updated to June 2025 by @metoffice.gov.uk @climateuea.bsky.social and @ncas-uk.bsky.social

It’s migration time which means SO MANY BIRDS!! Here are just a few you might see passing through the US and Canada. #birds 🌿 🧪

🚨New paper alert! Kaushal N et al. have published in CP: "Perspective on ice age terminations from absolute chronologies provided by global speleothem records" which uses the PAGES #SISALv3 database! 🔗 pastglobalchanges.org/publications... #GlacialTerminations #Paleoclimate #Speleothems

E-see you all the climate enthusiasts at our upcoming ICCP speleothem lecture series on 25th September with Dr. Stacy Carolin Zoom link: pusan.zoom.us/j/8901635789...

Great work @jschnaubelt.bsky.social !

Strengthened Pacific zonal SST gradients can arise from a number of asymmetric and/or spatially varying features - ocean heat flux, radiative forcing, surface radiative feedback, surface-air relative humidity contrast. or a more zonally asymmetric wind speed journals.ametsoc.org/view/journal...

Thrilled to share my first thesis article in GRL! We reconstructed 131 years of Eastern Amazon wet-season rainfall using C. odorata tree-ring oxygen isotopes. This work offers a paleoclimatic perspective that is crucial for understanding the Amazon’s hydrological cycle. dx.doi.org/10.1029/2025...

Congratulations to Zilu Meng and coauthors - this work definitely advances last millennium data assimilation - looking forward to digger deeper into this journals.ametsoc.org/view/journal...

A new paper out in AGU Advances led by Xiaoqing Liu in which we try to take the 'time' out of paleo and focus on the pattern of warming for wide range of global warming levels. agupubs.onlinelibrary.wiley.com/share/K8WWRP...

The last 48 hours have been surreal here in Kathmandu! Nepal’s youth recently started a viral online campaign exposing and targeting corrupt politicians & their children’s lavish lifestyles while the rest were struggling! Rattled, they tried banning social media altogether and all hell broke loose!

Controls of the global overturning circulation of the ocean by Roquet et al 🌊 looks like a neat review! www.nature.com/articles/s41...

Afternoon folks. I'm delighted to announce our manuscript "Speleothem evidence for Late Miicene extreme Arctic amplification" was published online today. Happy reading! @speleoseb.bsky.social @thomasopel.bsky.social cp.copernicus.org/articles/21/...

Shoutout to @harryjgrosvenor.bsky.social !

Honoured to have received an Honourable Mention at #ICP15 in the Paleomonsoon/Monsoon session. Grateful to my advisor @carbon8.bsky.social — this achievement wouldn’t have been possible without his constant guidance and support.

Glad to see advances in Tex86 in speleothems to understand temperatures with amazing precisions. Speaker : River Shen from NTU Taiwan.

It’s that time of year again! #MinCup25! Vote for your favourite mineral as long as it is #calcite! In the form of #speleothems this mineral tells us so many stories about our #climate through the ages! 🤩 from precipitation to temperature to wildfire to past forests…

Really amazing to see a science communication panel at #ICP15

Day 3, #ICP15 , perspective talk by Bridget Wade @es-ucl.bsky.social The Oligocene - with ice and a twist 🙏🏼

Great talks today at #ICP15 Day #3 with @hl-ford.bsky.social providing a comprehensive overview of Pliocene tropical Pacific 🏝️ model-data 🖥️ comparisons, & Lukas Jonkers highlighting recent advances in foraminiferal 🐚 paleoecology & pelagic paleobiogeography 🌊

#ICP15 Johann Klages explains the Evolution of the Antarctic Ice Sheet from green- to icehouse conditions

🌊 In 2023, the ocean carbon sink weakened for the first time in a record-hot year 🌡️🌎 Our new study in Nature Climate Change quantifies this unexpected decline and explains how it came about. 👇 doi.org/10.1038/s415...

Awesome performance at #ICP15 concert by my advisor @carbon8.bsky.social and his team.

Next up #ICP15: I really enjoyed Xu Zhang's interesting new results on how #Antarctic ice-sheet dynamics may have played a pivotal role in modulating atmospheric CO₂ and the resulting intensification of #interglacials after the mid-Brunhes event around 400,000 years ago!

Day #2 of #ICP15 kicks off with talks on Overturning #ocean Circulation variability & impacts—1st, Cristiano Chiessi on how Atlantic MOC changes need to be factored into Amazonian tipping-point assessments. Now: Frerk Pöppelmeier on future #AMOC changes & how a "full collapse" may not be likely...

Great start to Day 2 of #ICP15 by Frerk Poppelmeier talking on AMOC

Raja Ganeshram delivered yesterday's plenary lecture on #ocean #deoxygenation variability & showcased some amazing decadal-scale #nitrogen isotope δ¹⁵N records across multiple (de)glacial #climate states. #ICP15

#ICP15 Day 1 had a busy poster session and finished after a perspective talk by Raja Ganeshram on Climate forcing on ocean deoxygenation 🙏🏼

This week, I am grateful to be at the International Conference on Paleoceanography #ICP15. Great start this morning with a tour of #Boron isotopes & #Cenozoic CO₂ reconstructions from @eleniwater.bsky.social & @chalkyoceans.bsky.social. Nice to see all the paleoceanographers in #Bengaluru!

Great talk by @seavdavis.bsky.social right now—highlighting dynamic #oxygenation changes over the last glacial cycle & showing how Globorotaloides hexagonus is a key species that is able ot survive in low-oxygen marine environments. #ICP15

Happening now at #ICP15: Arvind Singh from Physical Research Labs, Ahmedabad, talks about #iodine (I/Ca) measurements in planktic #foraminifera from Arabian Sea #sediments recording glacial-era expansion of the oxygen minimum zone.

⏰ Reminder: Tomorrow I’ll join @climtip.bsky.social to discuss the future of the AMOC. Our Nature study suggests collapse is unlikely this century — but the risks remain critical. 🗓️ 2 Sept, 14:00–15:00 CEST 👉 tum-conf.zoom.us/j/6933421034...

Inequality in human exposure to future climate extremes ... hitting low-income countries hardest, mostly due to rapid pop growth, not just climate change As event severity rises, exposure inequality lessens, but compound hot-dry events still create massive risks... www.nature.com/articles/s41...

I know I don’t need to say, but this would not be good… High-emission scenarios show possible AMOC shutdown after 2100 phys.org/news/2025-08...

I'll be in #ICP15 talking about speleothem based ISM convection reconstruction across the last six centuries - Anyone want to chat some science - lets meet !

#ICP15 welcomes you if you are attending pre-conference workshops on #foraminifera #proxies @oscarbranson.bsky.social and #paleotemperature Antje Voelker 🙏🏼 Detailed programme 👇🏼

Doing what I love to do the most - caving in south India !!! Photos from today (summer monsoon season) and you can see how lush green it is ! Thanks to my PhD supervisor and the best mentor @carbon8.bsky.social for giving me the opportunity !

The new DOE Climate Report claims that "natural climate signals" like the Pacific Decadal Oscillation (PDO) could have affected global temperatures, but a new study shows that the observed PDO trend since the 1980s is human-caused by greenhouse gas emissions. www.nature.com/articles/s41...
