“We cannot withdraw from the fact that over 1 million species of plants and animals face extinction.”

IPBES remains committed to its mandate to provide the most credible science and evidence about biodiversity to all decision makers and actors.

Right side shows a photograph of a man wearing glasses, dressed in a dark jacket and grey shirt, seated at a conference table with a microphone. The IPBES logo appears at the bottom with the tagline "Science and Policy for People and Nature". The design features white typography on the dark green background, creating a professional contrast. Several small pins or badges are visible on the speaker's jacket.

Ecologist here, we know plenty about the diversity of life, and as the @britishecologicalsociety.org we actively support the inclusion of trans people alongside all the many ways of simply being human. Dawkins does not represent or speak for us.

I’m really upset about this as a Guiding member for over 30 years. We’ve always welcomed trans girls and made a safe space for them. Not sure this will make any difference but if you can sign please do: c.org/SR6NcW46B7

Land-use changes threaten the safety net for birds

Although the title misses the point by a long way. It's not the "safety net for birds" that is at stake here, but the "safety net provided by birds" - the resilience of ecological functions supporting the whole ecosystem.

Twitter accounts are based in Russia. BlueSky accounts are based in homes with, frankly, too many books, plants, obsolete cables, and pieces of rustic pottery, that could do with a bit of a tidying up, to be honest.

In 2019, UNESCO in Paris, hosted the 7th Session of the IPBES Plenary, which approved the landmark #GlobalAssessment

It is therefore fitting that next week, UNESCO will again host IPBES for the First Author Meeting of the #2ndGlobalAssessment.

Stay tuned for updates! #SciencePolicy #Legacy
