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.

how carbon removal technology is like a time machine. They are both pipe dreams and distract from real helpful actions.
We will likely need both carbon reduction and sequestration to actually be effective in reducing carbon emissions in general. Here's an article that touches on that and as well as goes over concerns about relying too much on carbon dioxide removal.
I get that carbon collection on industry exhausts are necessary and a must have for a lot of products (like steel). But other than that this is silly. Plant trees and use them to build stuff, plant new trees after that. Rinse, repeat.
I think we need to go a step further. The article I linked earlier touches on how several natural carbon sequestration systems rerelease carbon seasonally or have other implications. Seagrasses release carbon when water is warmer than usual. Trees release carbon during forest fires or from natural decomposition, and even potentially cause local atmospheric warming due to a low reflectivity. Artificial methods of sequestration are necessary, whether as systems that directly capture atmospheric carbon and store it or as systems that interrupt the process of natural decomposition or combustion and divert it to storage or further processing.
