Edenhofers "CO2 Entnahme als Planetarische Müllabfuhr zur Risiko- und Darseinsvorsorge" auf der #CDR Konferenz ist, in der Tat vermutlich ein einfacher zu kommunizierendes Bild als Netto-Negative Emissionen für Temperaturzielerreichung durch Carbon Dioxide Removal 😅

Steffi Ober vom @nabu.de stellt fest in der #CDR-Konferenz: Flächen und Energie sind Limitierungen für CO2-Entnahme, und hier sei zB die Reduzierung des Fleischkonsums wichtig um Flächen für Biomassebasierte Verfahren zu haben.

Edenhofer plädiert für eine Erweiterung des EU ETS, emissions Trading Schemes, um #CDR Handel und Realisierung zu finanzieren, und sagt es brauche ein Portfolio an Optionen, natürliche wie technische. @terra-cluster.org

"Es gibt kein vernünftiges Temperaturmanagenent der Erde ohne CDR", da keine andere Möglichkeit besteht, die Deponieablage die wir bereits gefüllt haben abzutragen. Ottmar Edenhofer bei der #CDR Fachkonferenz. Es gibt akuten Handlungsbedarf, wie die Lücke zwischen Anspruch und Wirklichkeit zeigen.

Eröffnung der Konferenz im Bundesumweltministerium zur Langfriststrategie Negative Emissionen. Parlamentarische Staatssekretärin Rita Schwarzelühr-Sutter fordert auf, das 1.5 Grad -Ziel im Blick zu behalten, und CO2 Entnahme hier mit zu denken @umweltministerium.de @terra-cluster.org

Ohne einen schnellen Ausbau der CO₂-Entnahme sind die globalen Klimaziele kaum erreichbar. Das zeigt der neue #SoCDR-Bericht, an dem auch Forschende aus CDRterra beteiligt waren. Bis 2050 droht eine Lücke von über 5 Mrd. Tonnen CO₂ pro Jahr. Mehr: cdrterra.de/news/neuer-s... #CDR #StateofCDR

2026 is now on track to be just above 1.5C for the year as a whole in ERA5, though exactly how warm it will be is conditional on how quickly El Nino develops in the latter half of the year.

Monday ice update - #Arctic sea ice extent is currently the 3rd lowest on record (JAXA data)... • about 300,000 km² below the 2010s mean • about 860,000 km² below the 2000s mean • about 1,350,000 km² below the 1990s mean • about 1,760,000 km² below the 1980s mean More: zacklabe.com/arctic-sea-i...

🆕 WMO confirms: El Niño conditions are developing and are set to influence global temperature and rainfall patterns, increasing the risk of extreme weather over the coming months. Most forecast models suggest it will be at least moderate – possibly strong. Be prepared. More info➡️ bit.ly/4e1hvLt

Science is, indeed, for everyone!

#stadtradeln2026 is coming to an end in Tübingen this weekend. The contribution to our @terra-cluster.org team was challenging. May was just too short, with #EGU and post-EGU sniffles and all. We did our best @unituebingen.bsky.social :-). Loads of fun, looking forward to next year 🚲🚲🚲🚲!

Across the world, scientists are studying Earth systems and how they affect flora, fauna, and everything in between.🐌 On this #BiodiversityDay, check out @jgrbiogeo.bsky.social to read about this important work: spklr.io/63325EMyPS#BiodiversityDay #AGUPubs #Biodiversity

🌱 Landnutzungssektor (LULUCF): Statt zur vorgesehenen Emissionssenke zu werden, bleibt der Sektor laut Projektionsdaten bis 2050 durchgängig eine Treibhausgasquelle. Die tatsächlichen Emissionen dürften sogar noch über dem ausgewiesenen Wert liegen.

Fun debate today on future of palaeoclimate modeling at @marumunibremen.bsky.social, with Louise Sime from @bas.ac.uk, @fpoeppelmeier.bsky.social from Bern, Gerrit Lohmann from AWI and Kira Rehfeld from @unituebingen.bsky.social / @terra-cluster.org: 🌎 history has a lot to tell for the future!

Walking to the train station on the way to the palmod (www.palmod.de) open science conference in Bremen I pass the city of Tübingen old town... No boats out yet... but beautiful and peaceful even (too) early in the morning 🤩. Have a great Sunday!

Great to see this Alpine ice core data published, showing the potential of Mont Blanc glaciers for paleoclimate reconstruction! Kira says: "Dietmar, if you can see this from above the clouds - you were right about the Glacial ice (even though I could only speculate about this in my diploma thesis)."

Happy to announce that #TERRA was selected as a #ClusterOfExcellence by @dfg.de. K. Rehfeld (@past2futureclimate.bsky.social‬), O. Cirpka & myself express greatest thanks to @unituebingen.bsky.social‬, our mock-reviewers & the entire TERRA-team for the relentless support. Let's start the endevour!
