If we let it. The IPCC has issued another urgent warning: Misuse of land and soil contributes a great deal to Global Warming. Fixing that misuse would go a long way to solving the problem. How, then, do we make that profitable to all of the varied users and misusers of land?

Climate Change and Land: An IPCC Special Report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems.

tl;dr

An estimated one quarter of total anthropogenic GHG emissions arise mainly from deforestation, ruminant livestock and fertiliser application, and especially methane and nitrous oxide emissions from agriculture have been rapidly increasing over the last decades. Globally, land also serves as a large carbon dioxide sink, which was estimated for the period 2008–2017 to be nearly 30% of total anthropogenic emissions.

Due to the current magnitude of GHG emissions and carbon dioxide removal in land ecosystems, there is high confidence that greenhouse-gas reduction measures in agriculture, livestock management and forestry would have substantial climate change mitigation potential with co-benefits for biodiversity and ecosystem services

We have been getting bad news for decades from all sides in ecological research. The IPCC wants us to understand how much worse it has gotten, and how urgent it is to find and implement solutions. However the Good News about sequestering many tens of gigatons of carbon over several decades in soils and plants is new.
