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.

Most of the climate benefits from "tree-planting" really derive from reforestation. Forest ecologies are complex and take decades-centuries to develop to the point where they can function as meaningful carbon sinks. The cycle was covered in my biology 101 class in college, can't find a graphic covering the overall cycle at the moment, but the point is it's not just lots of trees = carbon sink, it's the enormous community of life that develops around (and also often precedes) the trees that makes forests -- not just "groups of trees" or even "a rather large group of trees" -- function as carbon sinks.
It's a fantastic idea for the long-term considering all the other problems we're running into with global deforestation anyways, but businesses whittled the concept down to plant tree = good because that's easier than dealing with the causes of global deforestation (hint: businesses)
If you’re interested in the complex ecology of forests the book “The Hidden Life of Trees” is a really good book that talks about all of the symbiotic relationships of forests and how they work together to make a forest strong. Can’t recommend it enough
Good book. I think the thumbnail sounds up the main problem with mindless tree planting. Monocultures, isolated from historic biomes won't become healthy ecosystems at all but fall prey to bugs and disease. Same as with human culture, biodiversity is needed for it to thrive.
