We asked you to save the date and now it is time to join in the best (only??) tephra meeting! Come to Catania, Sicily, at the foot of Etna in September to talk all things tephra - chronology to climate to hazards. Oxford Tephrochronology Group Swansea Volcanoes and Tephra Group IAVCEI Tephra Hazard Modeling Commission cot.iavceivolcano.org/cot-intimate-t…

Further details for this years CoT-INTIMATE-THM International Conference in Catania (Italy) can be found on our website: cot.iavceivolcano.org/cot-intimate-t We hope to see you in Catania!

🚨New Paper @EvelienvDijk93: The #Holocene wasn't a period of #climate stability. It saw 11 long-lasting cold periods (LIA-type events) forced by🌋🌋clusters, and seasonal-to-decadal cold extremes not seen in the Common Era.

Thanks CNN for summarizing our ice-core detective work of unlocking Earth’s explosive past. A short🧵on the 10 shown eruptions with the latest complete dataset shown at the end. 🌋🇬🇱 #Zavaristski #Tambora #Laki #Mélébingóy #Huaynaputina #Kuwae #Samalas #Eldgjá #Ilopango #Okmok

The Beyond EPICA ice core drilling has finally reached the bedrock at a depth of 2800 m: this is a huge success for our project and for ice core science! We have strong indications that 1.2 million years of climate record are stored in the uppermost 2480 m of ice. 📸©PNRA/IPEV

📣New paper in pnas by Hutchison W et al. from VICS Working Group have revealed which mystery 🌋volcano eruption caused significant NE climate cooling from 1831–33 CE using well-dated ice cores and stratigraphic records. 👏Congratulations to the entire team! pnas.org/doi/10.1073/pn…
