#Los Chocoyos supereruption occurred 79,500 years ago, with Earth's climate recovering within decades. Ice core analysis from #Greenland and #Antarctica challenges theories on supereruptions triggering ice ages. @NaturePortfolio https://t.co/dbFcA6hWA2 https://t.co/QqKWRc62qP

Los Chocoyos super-eruption from Atitlán caldera (🇬🇹 80 ka ago) — the single largest known sulfur injection in 100 ka — did NOT lead to an Ice Age!

A mystery eruption, solved?

Uncovering an eruption that caused global temperatures to drop took geologic detective work.

Volcanic sulfur detected in a cave in Germany 🇩🇪 from the Laacher See eruption 🌋13,000 years ago synchronizes the timelines of climate across Greenland and Europe!

📣New paper in @pnas by Hutchison W et al. from @VICS_PAGES 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!

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. 🌋🇬🇱

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.

🚨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. @unibern @UniOslo @ERC_Research

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.
