The geoengineering technology simply isn’t here. There’s no strong capitalist incentives for such tech to emerge or be developed.

There’s no way we can eliminate the use of fossil fuels in the next ten years. There’s no way we can change consumer diets to rely less on methane producing animals. There’s nothing we can do to stop the acidification of oceans and the collapse of aquaculture. And when the permafrost melts and releases methane exponentially into the atmosphere it’s game over.

Unless we have a way to siphon out gases from the atmosphere, we’re finished.
