There are forests and soils and mycelial networks that drive more carbon into the soil, there are solutions like biochar for taking wood and plowing it into the soil, allowing a new tree to grow in that tree's place, there are algea and plankton in the ocean that actually make carbon fall to the ocean floor (the article above just taught me that), there are people working on mechanical and chemical ways of removing carbon from the air.
All of these sinks together cannot compete with how much we are still, *increasingly*, pumping and digging out of the ground.
That has to stop, that's step zero, and then all of these ways of reducing existing carbon can be our way to get back to 20th century climate, maybe some time in the 22nd century. But that's currently a fantasy, as we're not even stopping the escalation of burning 300-million-year-old trees and other plants.
(I had to look it up, trees showed up 370 Mya, so they're in there) 😅
