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.
There is absolutely no way to remove carbon from the atmosphere in quantities that will make any kind of difference. The only thing we can do is to stop polluting. This does not start with cars, it starts with cruise ships and industry. And since we all know that will never fucking , just celebrate the end of the world.
Honestly, I don’t even know why the sub exists.
Seconded. Plant life has spent hundreds of millions of years perfecting carbon capture. We're so cocky as a species, thinking we can speed-run terraform tech and that might somehow allow us to continue our culture of constant growth without consequence.
Relying on carbon capture to fix climate change is like calling in a construction company to rebuild your house while it's still actively on fire.
Probably worth trying though?
We can concentrate energy way better than plants can, so the possibility is there. The problem is that as Climateworks is a private company, they are not releasing the data that might help others.

I like those green algae bubblers set up on the exhausts of thermal powerplants, though, those are fun and work (partially), unlike this carbon capture fairytale bullshit.
isn’t there already carbon capture with biochar?

The reasonable RCP pathways we're trying to follow require us to remove a net 2 Gigatons of CO2 a year from the atmosphere per year.
And yeah we can't really do it this way because of entropy unless we work a miracle, best we can do is tip the Earths natural carbon sinks into our favour but we're doing the exact opposite of that.
Those carbon sinks can also take millenia to find a state of equilibrium as well.
I know I sound like a pessimist so here's my take from this, these companies have insidiously compartmentalised an existential threat to our species to the confines of the economy.
These companies will never amount to anything significant, they will ride a model of perceived hype around some vaporware tech that flies in the face of thermodynamics.
This detracts from real solutions to a very real problem that falls beyond the comprehension of these arseholes and they don't deserve our attention much less the time of day.
