It is beautiful to see how wind and gas follow the same curve: it means that increasing wind will push out gas directly! Wind produces the most on months with high demand.

En même temps, on retrouve des fossiles de dinosaures qui ont a peine bougé en 100 millions d'années sous moins de 10 m de terre. Donc un truc enfoui sous 1000m sous terre, dans une des couches géologiques les plus stables qu'on connaisse, ça ne m'effraie pas vraiment.

All indicators point towards a global food crisis in the coming months: production decreasing in Russia, tensions on fertilizers because of the Iran war, historic heatwaves in Europe, record el Niño forecast. Governments should take all corn and soy devoted to livestock and store it for humans.

Totally disagree on this one. Letting states run everything gives even more power to corporations, who can blackmail local governments, forcing them into a competition of ever lower corporate taxes, environmental standards, labour laws etc. It would be far better to have more federal legislation.

It's funny to have to make this case but tbqh we don't make it enough: human efforts to counter fossil fuel use have had *at least some* effect on total greenhouse gas emissions since the signing of the Paris Agreement in 2015, and there's some evidence to back up this position A lil thread 🧵

my takeaway from climate week nyc is that "climate storytelling" is a little too much "we must reimagine our deepest souls in relationship to mother nature and the moral abyss of the polycrisis into which we must now stare" and not enough "ok but get a heat pump"
