10bn tonnes must be captured from the air every year to limit global heating to 1.7C, says Johan Rockström

Problem is this part:

To achieve this through technological means, such as direct air capture, would require the construction of the world’s second biggest industry, after oil and gas, and require expenditures of about a trillion dollars a year, scientists said. It would need to be done alongside much more drastic emissions cuts and could also have unintended consequences.

That makes it incredibly unlikely that this kind of removal will be done.

Is silence7 a bot? Just curious. If not, good job keeping this sub active.

Regarding this article: yeah... we're fucked. Technology isn't going to magically save us, and DAC can't scale anywhere close to what we need. It's still worth reducing carbon/methane emissions as much as possible since every little 0.1 deg C makes it that much worse, so to any doomers (and API/Exxon astroturf bots) we still need to take action to remove Big Oil as an industry.

As usual, just sharing this: The dirty dozen: meet America’s top climate villains
