@benlockwood.substack.com I have prepared a rebuttal paper. Are you interested in collaborating?

We just published an especially relevant warning from Craig McLean, the acting chief scientist and head of NOAA Research during "Sharpiegate." He defended scientific integrity—and was removed as chief scientist. Scientists can't be silent now either, he says. www.motherjones.com/politics/202...

I paid the price for speaking out about “Sharpiegate.” Scientists can’t be silent now, either.

By definition, numerical weather models require international data. The atmosphere knows no geopolitical boundaries: any model that begins and ends at its country’s border is unable to generate reliable predictions until after a weather system crosses its boundaries. Which defeats the purpose!

Would appreciate a RT from the scientists for this one! We have 665 scientists in the spring database and I want to get us to about 1000 before we set the teachers loose on the database for January matches.

According to the City of Paris, in the last 10 years 150,000 trees have been planted and 45 hectares of parks created in the city, to improve quality-of-life today, and also to help the city adapt to and manage summer heatwaves of 50℃ (122F) by 2050. On top of everything else Paris has been doing.

Do #ForestEurope indicators work for #biodiversity? We tested them against field-sampled multi-taxon data (a lot of them!) and ... only some of them moderately relate to species richness! Read the recent article led by #YoanPaillet doi.org/10.1016/j.bi... Time for a data-driven revision!

As you go out on your winter walks, have a careful look at tree buds. A bud is an amazing structure. For many temperate trees, all of next year's growth is already in the bud - leaves, buds, internodes, even flowers. That means that this year's weather already established next year's growth.
