Antarctic Team Drills 6 Million Years Into Earth’s Past
At the end of the Earth there’s a record of sorts, preserved in layers of layers of Antarctic ice—you could even call it our planet’s memory. Now, scientists have unearthed a new chapter in this...

Hydrology Paper of the Day @nielsjdewinter.bsky.social on paleoclimate during the middle Eocene: understanding possible scenarios of the future by studying the past; an δ18O dataset from gastropod shell carbonate; seasonal temperatures indicative of a climate with monsoons; and models of temperature
⏰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.

I read a lot about paleoclimate during the human era, and my one observation is:
1. humans have survived some very wild temperature swings
2. relatively mild climate swings have set off wild secondary effects / chain reactions and really sucked for humans

Dans la section consacrée au sixième rapport d'évaluation du GIEC (le plus récent), il est question d'« Independent reviews, such as by the Climate Intelligence group », qui critiquent des biais dans le rapport.

![AR6 has drawn critiques for selective emphasis on model projections over observational trends in areas like disaster losses and tropical cyclones, where claims of increasing intensity were rated medium confidence despite stagnant global economic damages adjusted for population and wealth growth.[66] Independent reviews, such as by the Climate Intelligence group, identified biases in chapter selections favoring alarmist interpretations and underrepresenting dissenting empirical studies on sensitivity and extremes.[82] These concerns arise amid AR6's reliance on self-reinforcing academic literature, where institutional pressures may amplify consensus on causality while downplaying natural variability contributions documented in paleoclimate records.[58]](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:uka3hyl3scu6jg24can43msb/bafkreifgyjxmyhqczv2sxicamd4tzzx6kqhzkhhzc3kemqbei4xlpbbz6u@jpeg)

I've experienced this teaching my intro paleoclimate course (which is for any major/year for gen-ed credit) ... now, I do some *very simple* activities in the first couple weeks to provide some foundation ... by the end of the term they are pretty comfortable with it

We welcome contributions from very broad AMOC impact types (physical, biogeochemical, or socioeconomic), timescales (paleoclimate, recent past, future projections), forcings (variability, forced trends, abrupt/tipping) & tools (Earth System/regional/simple/economic models, reanalyses/observations) 🧪

Combining #climate simulations, trained deep learning models, and understanding of The Atlantic Meridional Overturning Circulation (AMOC) variations from observations and past/future climates enables more accurate projections of future AMOC tipping.

Excellent work! Using stalagmite δ18O records to correlate paleoclimate shifts with the Western Zhou collapse (~771 BCE) shows how geological archives illuminate historical events. High-resolution reconstructions like this are crucial for understanding climate-society interactions.
