Geoengineering to fix climate change could harm biodiversity, according to two modelling studies.
Bioenergy with carbon capture and storage needs a lot of land, while solar geoengineering could, if introduced and then abruptly stopped, cause climate swings too rapid to allow for species to adapt. For a more extended summary, see Carbon Brief’s excellent briefing here. See also the image below for results from one of the papers.
