Please help Project Drawdown and our work to deploy science-based climate solutions out into the world.

It sometimes feels impossible to build a better future, but I assure you that it is not. A better future is possible, but only if we choose to pursue it.
Tomorrow is #GivingTuesday! The spirit of giving is coming alive around the world — and you have the power to lead. When you donate tomorrow, you can DOUBLE your impact with a generous match. Together we can make the impossible possible!

@atinygreencell.bsky.social , turns out I am growing a Korean perilla (Perilla frutescens) that is doing a consistent triple whorl, spontaneously. Happy to ship a sample, once shipping between our countries is a go again

Does nature observe city limits? Why no, it does not. Menno Schilthuizen´s ´the urban naturalist´ is full of fascinating stories of life adapting to the urban environment and the people studying it.

Second electroplating experiment, for an anode for what will be an ion-plasma wind tunnel. Electroplating is fun and easy, I can live with that!
