But he that dares not grasp the thorn. Should never crave the rose! #Landesgartenschau2024 #Wangen

Come join us Sep 8-16 to talk about all things tephra in Sicily! 🌋 Our friends from IAVCEI Tephrachronology are putting together a fantastic workshop. Hazard and climate enthusiasts welcome! Abstract/ECR fund deadline = June 17. All info 👇

🚨New Paper Evelien van Dijk: 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. Universität Bern Universitetet i Oslo European Research Council (ERC)

The decline in emissions in planet-cooling sulfur dioxide since 1980 is also reflected in ice cores from Greenland where sulfur concentrations are approaching again preindustrial levels. 🏭🌡️ Leon Simons Zeke Hausfather

The new study on the impact of volcanic eruption on #Iceland on the early #medieval #climate in Europe and #Byzantium made it also now into Scandinavian media :)

Calls for a specific paleoclimate chapter in IPCC #AR7 to encompass an in-depth assessment of uncertainty in paleoclimate reconstructions spanning the past 2000 years.

Neuer Blickwinkel auf den #Hockeystick :
🌡️
Wir argumentieren, dass die Beschränkung des #IPCC auf eine einzige Temperaturrekonstruktion für die letzten 2000 Jahre eine 'unzureichende Zusammenfassung unseres Verständnisses von Temperaturschwankungen' war.

We've got a new paper in Communications Earth & Environment led by Jan Esper and Jason Smerdon. We argue that the IPCC's focus on a single Common Era temperature reconstruction was an 'insufficient summary of our understanding of temperature variability' and we provide a broader context

#Vulkanausbrüche auf #Island waren im Frühmittelalter dafür verantwortlich, dass u.a. das Schwarze Meer gefroren war. Dies zeigt eine internationale #Studie Oeschger Centre #unibern mit Beteiligung der Austrian Academy of Sciences: sohub.io/5usm.

The article in Communications Earth & Environment of Imogen Gabriel & Michael Sigl (@unibern) et al. shows how an active period of Iceland´s volcanoes affected the #climate from Ireland to #Byzantium & Egypt between 750 and 940 AD.

And here are our projections for (minor) climate forcing and temperature response, for emissions to date. We used 0.4 +/- 0.15 Tg SO2 and 19+/-3 km height based on estimates by Simon and others 🙏 Anyone can use our simple climate-volcano tools on volc2clim.bgs.ac.uk 🌋

First first-author paper is out! 💪

We investigate the global climatic impact of the Mt Samalas 1257 eruption, using model-multi-proxy approach + potential historical impacts. Such a learning curve project, but so thrilled to see it finally shared.
