Worst then that, it is an excuse to continue or increase emissions and distract people from real solutions. We need to reduce emissions first. It might be valuable someday once the low hanging fruit has been dealt with.
Its a waste of valuable resources that could be used on known, more efficient ways of reducing emissions. Carbon capture isn't here to save us, it is here to save oil and gas
It's not a single bullet solution. There is no single bullet solution.
It is one bullet, in a hail of bullets fired at the problem. They'll all be needed.
Use coal to pull carbon from the air. Makes total sense! /s
But, it’s “clean coal!!!” /s
tl;dr waste of money
It's a big fuckin' mystery.
I would say its a yes and. Yes it costs a lot of money and it's not as efficient as trees long term. But Trees + these machines + no longer burning and releasing CO2 at the current rate + land rewilding = a chance at survival.
Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
