Biodiversity conservation has an evidence problem — it’s time to fix it Globally, more than one million species are threatened with extinction, but often interventions intended to protect biodiversity are not rooted in robust research. The field has an opportunity to chan...

#DidYouKnow many conservation policies lack strong scientific evidence? The @ipbes.net #BizBiodiversity report highlights the urgent need for better data on what works and what doesn’t. Let's build a future where decisions are evidence-based!

Donald Trump: Schauspieler Ian McKellen hält Shakespeare-Monolog gegen US-Präsident Sir Ian McKellen ist für eindrucksvolle Filmrollen bekannt. Nun hat er in Stephen Colberts »Late Show« gezeigt, was er von der aktuellen US-Politik hält – mithilfe eines 400 Jahre alten Theatermonologs.

Gladys Mae West obituary: mathematician who pioneered GPS technology She made key contributions to US cold-war science despite facing huge barriers as a Black woman.

No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition.

Which just makes me want to share it again: www.nature.com/articles/d41...

The latest European Grassland Butterfly Indicator is out. It shows that grassland butterflies have declined by 47% since 1991, indicating a huge loss of grassland biodiversity. The data come from 16,150 transects & 15,000 volunteers. We are calling for urgent action. www.bc-europe.eu/documents/69...

US bars five Europeans it says pressured tech firms to censor American viewpoints online The State Department is barring five Europeans it accuses of leading efforts to pressure U.S. tech firms to censor or suppress American viewpoints.

To be clear: the CEO's of HateAid have recently been awarded the German Federal Cross of Merit for their support of human rights and dignity. Concepts rather alien to the Trump administration.

It should be: trust the scientific method. It will in most cases lead to much better results. This is a subtly different way of communication - honest, not arrogant - and may generate trust rather than scepticism.

The future of climate science is more diverse, more connected, and more collaborative.
We need every voice, every perspective, every mind to solve what’s ahead.
WCRP is building a climate science community that reflects the world it serves.

After 7 Decades of Measurements From a Peak in Hawaii, Trump’s Budget Would End Them

www.nytimes.com/2025/07/17/c...

As record heat continues to impact communities across the nation, this is what is in that proposed budget: 🌡️

"With this termination, NOAA will no longer support the National Integrated Heat Health Information System" (aka NIHHIS or heat[dot]gov)

Excerpt from proposed NOAA budget showing zero funding for Climate Laboratories and Cooperative Institutes

Proposed NOAA budget zeros out ALL climate laboratories and cooperative institutions.

GFDL, NSSL, GML, etc.

This appears to also end the US greenhouse gas sampling network, including at Mauna Loa, the oldest continuous carbon dioxide monitoring site on Earth.

The tongue of Rhone #Glacier ten days after my last visit. Can you guess how much ice melted away? 1️⃣ meter in terms of thickness! 1️⃣0️⃣ days... And that's just the beginning of the summer season.
We know the times are bad for the ice, but still it is hard to accept these numbers!

Den @deutschlandfunk.de.web.brid.gy Autoren Rassismus vorzuwerfen (sie zeigen die Geschichte der Wokeness nicht, wo es doch um den Punkt geht, dass in der aktuellen Debatte viele Menschen, links & rechts, glauben, dass die großen Probleme unter den Tisch fallen) geht am eigentlichen Thema vorbei.

Nein - der Autor ist kein naiver Bewunderer von Thiel, sondern zeigt nur die Faszination auf, die von ihm für viele ausgeht. Wenn Welt-Herausgeber und viele junge Männer heute glauben, die Zerstörung von Institutionen sei etwas tolles, muss das doch herausgearbeitet werden.

Doch - Peter Thiel ist äußerst intelligent. Das macht ihn, zusammen mit seiner libertären Einstellung und den Ideen einer bevorstehenden Apokalypse ja so gefährlich.

Had an inspiring talk from Dave Stainforth from @granthamlse.bsky.social today at @wegenercenter.bsky.social. What can you learn from models? How to design ensembles? And how to spend our money?

We had a really interesting talk by Mathias Rotach from @uniinnsbruck.bsky.social here at @wegenercenter.bsky.social. He showed us the complexity in modeling the mountain boundary layer, and that it is still a long way to robustly represent climate change in local mountain valleys.
