We had only recently passed 350 ppm when I started my PhD in Earth System Science, already a value understood to be dangerous and a threat to society.
And now, 33 years and 30 COPs later, we are at a value that is unprecedented for the past 3 million years and maybe even the past 8 million years.

One of the first people I met in vertebrate paleontology. A terrific guy and a fantastic artist. Gone far too soon.
Got informed about some sad news. Garfield Minott, a prolific dinosaur modeller, special effects and palaeoartist, recognised for contributions to the description of dinosaur binocular vision, passed away at age of 58.

Wonderful remembrance of the great Philippe Taquet by my friend Didier Dutheil. Sad news indeed.
Very proud to have been part of the team that honored him by naming a dinosaur species after him—and a most bizarre one at that (which, as it turns out, was found by Didier).

Super cool experimental study demonstrating how warming and species richness alter mass-abundance structure of ecological communities.
Does body size predict abundance the same way in all environments, as predicted by the Metabolic theory of Ecology? Our new study challenges this assumption. Read it here: 📄 doi.org/10.1111/ele....
Biodiversity modulates the cross‐community scaling relationship in changing environments
Organismal abundance typically declines with increasing body size, with metabolic theory predicting a universal size–abundance slope of –0.75. Using protist microcosms across gradients of species ric...

Trophic rewilding depends on the assumption that replacing lost megafauna with alternative species can generate similar benefits. This new review by Bescond-Michel et al. challenges that belief. 🌏🌐🧪
Harms of introduced large herbivores outweigh benefits to native biodiversity - Nature Communications
Using impact assessment frameworks, this study shows that the introduction of large mammalian herbivores outside their native range has predominantly caused negative impacts on native biodiversity globally. The authors advise caution regarding their further intentional introduction for conservation purposes.
