Washington Post: Humanity’s greatest ally against climate change is the Earth itself. Ecosystems can draw down carbon and buffer us from the worst effects of climate change — but only if we protect them.
A 2020 analysis in the journal Nature Sustainability found that better soil stewardship could reduce emissions by at least 5.5 gigatons of carbon dioxide each year — about 15 percent of current annual emissions.
In a study in the Proceedings of the National Academy of Sciences (PNAS), they concluded natural climate systems are capable of storing almost 24 gigatons of carbon dioxide per year — roughly two thirds of what people emit. About half of that sequestration would be cost-effective, meaning enacting the necessary protections would cost less than the consequences of keeping that carbon in the air.
