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.

Carbon capture, illustrated:
Not to say we shouldn't try to pull CO2 from the atmosphere, but I just don't see how we can do that without it also being permission to keep emitting at current levels.
If you look a the physics and engineering challenges of attempting to pull CO2 out of the atmosphere, you'll very soon reach the conclusion that it's better to stop CO2 emissions at the source, or to reduce activities that cause CO2 emissions.
The only people who would rather put pollution into the atmosphere, then spend vast amounts attempting to take it out again, are those whose profits come from selling the oil.
The technology is here and it is developing at a rapid pace. There are a lot of clever ways to remove CO2. Keep in mind “CDR” - carbon dioxide removal and “CCUS” - carbon capture, utilization & storage are two different approaches to reducing atmospheric CO2 concentrations. CDR includes soil carbon sequestration, bio-char, ocean alkalinity. CUS is storage of supercritical CO2 between the pore space of permeable rock.
