This could include expensive large-scale carbondioxideremoval or risky "solar radiation management".
2
However, these methods of large-scale carbondioxideremoval tend to be slow-acting, costly and could be challenging for agriculture, sustainability and biodiversity.
3
Several adjuncts to mechanical ventilation, including heliox, general anesthesia, and extra-corporeal carbondioxideremoval, can be used as life-saving measures in extreme cases.
4
The scenarios also require carbondioxideremoval, changes to agriculture and forestry land use, as well as bioenergy with carbon capture and storage.

Carbondioxideremoval (CDR) techniques would suck the greenhouse gas out of the atmosphere and lock it away underground or in the oceans.
