A team of researchers led by Christopher Trisos of the National Socio-Environmental Synthesis Centre at the University of Maryland, US, has now modelled the effects of abrupt changes in potential long-term SAI geoengineering projects.

The scientists imagine a scenario in which SAI projects continue to 2070 and then are quickly halted due, most likely, to mercurial politics. Using a geoengineering climate model simulation called the Geoengineering Model Intercomparison Project, or GeoMIP, they found that such a quick change would reduce global biodiversity more than global warming itself would.

The reason for this is to do with the rate of climate change.
