Qu'est ce qui me révolte le plus ajd? Le dévoiement des mots ou dis +clairement: la trahison.
"Écoutez la science" quand ça arrange, s'y asseoir dessus qd elle dérange.
Dénoncer la désinformation devient une distraction qd les mots/faits ne signifient plus rien.

Absolutely. And we need to unmask the local-community - washing used by big corporations to cover up their polluting practices. Very present across the entire agri-food sector, not just for wine.

Remember that a large proportion of French grape producers ("large" in terms of revenues) are not small communities in beautiful villages but mass producers of industrial alcohol. It serves their shareholders to maintain a false image of winegrower identity.

I am all for helping ailing producers of things that can no longer be produced as easily or for which demand is shrinking, and both spirits and cars are good examples - but why not help them to transition to the production of healthier goods, such as pesticide-free vegetables?

Jon, I am happy to celebrate excellent scientists and extend my best wishes to James and Paul - but can we please stop the hilarious race for citations which are an extremely unfair way to estimate quality and finally benefit high-APC publishers more than anyone else?

Francesca Albanese—

"BREAKING: A new UN report finds that Israel’s assault on Gaza—with the destruction of health care, education, infrastructure, even the banking system—has erased 69 years of human development, marking the worst economic collapse ever recorded.

Das ist klima- & verkehrspolitisch völliger Irrsinn.

Wir brauchen weniger innerdeutsche Flüge, um die Klimaziele zu erreichen. Und gegen den Investitionsstau bei der Bahn helfen natürlich keine Subventionen für Airlines.

Die SPD darf diesen Angriff auf eine soziale Verkehrswende nicht mitmachen.

Australia was in the BELEM DECLARATION ON THE TRANSITION AWAY FROM FOSSIL FUELS for about 24 hours, before its Prime Minister declared that you need to extract more gas to help the transition away from fossil fuels.

Google at its peak was basically the best information retrieval system in human history and they and every competitor decided going from there to “you didn’t want answers you wanted half-assed auto-complete 80%-wrong hallucinations” in a few years was the right idea

Last week, six French scientists stood trial in Munich for a peaceful protest action in 2022.

While companies continue to profit off the destruction of our planet, scientists are prosecuted for alerting the public to the truth.

“This is the Amazon COP. If it ends with a decision that ignores Indigenous rights and props up offset markets that science says cannot work, it will squander the moral clarity of this moment,” a new op-ed argues.

We saw it with big tobacco, we saw it with the fossil fuels industry. When their own internal research showed the harm from their product, the defunded the research and attacked independent researchers coming to the very same conclusions.

Singing "Dies Irae" from Verdi's requiem, with Scientifiques en Rebellion @scientifiquesenrebellion.fr and the fantastic Orchestre de Nouveau Monde orchestredunouveaumonde.fr was a perfect way to take notion of government and private sector inaction during the 10 years since the Paris Agreement.

Depuis 30 ans de COP, les émissions de gaz à effet de serre augmentent de plus en plus vite. Et encore une fois, la COP 30, à laquelle participaient des pays pétroliers et lobbyistes des compagnies fossiles, n'a pas acté la sortie des énergies fossiles. C'est pourtant le cœur du problème !
