An upbeat feature in Nature on the potential to "cool down the planet" through CO2 removal. I disagree with most of it. Cool down? It would be huge to even slow the heating.

At least it quotes me at the end: “We are really trying really hard not to burden the next generation with the enormous impacts of climate change,” says Lucht. “We should also not burden them with having to implement planetary-scale carbon removal.”

Yes. But no: we're not really trying really hard.
