Gut.
Kannste die Uhr nach stellen, dass wir in Deutschland auch bald real auf allerhöchster politischer Ebene über den Bau neuer Atomkraftwerke diskutieren werden

Very interesting read. Colonialist narratives run deep and shape trajectories until today.

I learned something about myself from this article.

My climate bubble time line is scary. Two posts next to each other.

It is Feb 11 and fire emissions are higher than all annual totals before.
Analysis of #CopernicusAtmosphere fire emissions data clearly highlights the extreme nature of the recent devastating fires in Argentina/Chile with total estimated emissions for 2026 so far (1 Jan-10 Feb) exceeding all annual totals since 2003 for Chubut province🇦🇷 & most years for Biobío province🇨🇱

Next time someone asks you about energy and land use, maybe remind them that the ~35 million acres that currently grow corn for ethanol in the US could produce ~15 PWh per year of electricity from solar photovoltaics. That's ~3.5 times more than *total annual generation from all US power plants*.

We had a great discussion with leadership. Our cocoa and coffee work is often multidisciplinary and is a great way of avoiding thematic silos.

We could do better at showing our full capacity.
🌱 What does it mean for farms and landscapes to truly thrive? It means applying practical, place‑based science to restore soils, diversify production, and boost climate resilience. We shared this with CGIAR representatives during Day 2 at our Palmira campus 🌾🌳🐄.

In Göttingen können keine Wohnungen für Familien gebaut werden in der Nähe von Schulen, Innenstadt und Bahnhof.

Begründung: die Kinder auf der Skaterbahn und dem Fußballplatz wären zu laut, außerdem sei der Parkplatz wichtig für die Biodiversität.

🤝 Yesterday, we welcomed Sandra Milach, Chief Scientist at CGIAR, to the Palmira campus of @bioversityciat.bsky.social to demonstrate how, over the past five years, our science has reached 10 million people and improved 6 million hectares across farms and landscapes.

Always good to be cited by people who work towards solutions.

Looking forward to going through the library and discussing with Coffee Watch.
Roughly half the world’s arabica coffee-growing regions will become unsuitable for cultivation of the crop by 2050 due to climate change.

The nonprofit Coffee Watch has created an e-library of all the research ever conducted on coffee agroforestry to help producers grow the finicky plant.
The knowledge to save coffee already exists, now it’s in one e-library

Is the Greenland threat an attempt to break up NATO? Trump tried to leave NATO but was stopped. Is he now trying to get kicked out, then exploiting EU internal divisions to split Europe up between Russia and U.S. along cold war borders?
I can't believe I'm posting this video - but we actually have to have a conversation about the real world implications of America going to war over Greenland.

Let me walk you through it. It doesn't turn out well for us.

Gibt keinen dümmeren Unsinn als diese Böller-Verbieterei. Wollte man Gesundheits-, Umwelt-, und Klimaschutz diskreditieren und zu leeren Worthülsen reduzieren, man könnte sich kaum eine bessere Debatte wünschen.

Vielen Dank auch.

Some people in Germany believe that rising chocolate prices were caused by 'capitalists'. But the holiday season sees chocolate prices rise everywhere.

Global markets mean that coffee consumers and producers are linked by economic policies, carbon emission and climate impacts.

Nice story about how seemingly distant places and people depend on each other. 👇

Eine sachliche Diskussion scheint nicht mehr möglich.

Der zitierte Zeit-Artikel ist mehr Verschwörungstheorie als Qualitätsjournalismus. F4F springt voll drauf auf, weil es ins Narrativ passt.

Pragmatische Lösungen für Probleme scheinen niemanden zu interessieren in dieser Runde.
Superreiche setzen unseren Planeten in Brand und wollen nicht für die Folgen aufkommen, während die Ärmsten, die am wenigsten zur Klimakrise beigetragen haben, schon heute am Meisten darunter leiden. Cool und normal!

Mal was neues mit der Bahn. Nachts um halb zwei einfach Mal eine halbe Stunde in Fulda im Bahnhof stehen, weil der Zugführer einen Fahrplan für die Schnellfahrstrecke braucht, damit wir die Verspätung aufholen können, die durch das Warten auf den Fahrplan verursacht wurde.

Yeah, no shit. In Germany, universities refuse to teach climate change except in specific degree programs because somehow it is still seen as a biophysical issue, not a social one.
Sheeeet🤯

"when asked “what proportion of climate scientists think that global warming is caused mostly by human activities?” - only 30% of middle-school & 45% of high-school science teachers selected the correct option of “81 to 100%."

Adaptation to climate change was meant to be the easy part: As easy as 1,2,3 - what will the climate be? what are the risks? do something to reduce the risk!

It is going to rain? Put on a coat and keep enjoying life!

Adaptation increasingly turns out to be much harder than emissions reduction!
September 25, 2025 at 1:15 PM
Now reading - the conventional definition of adaptation as the process adjustment often ignores ambiguity from scales, justice, socio political realities and knowledge pluralisms.

Finally, some food for thought how we move away from a technocratic approach wich disregards people's needs.
