Sudden geoengineering termination could cause a huge warming spike

Abstract

Atmospheric concentrations of greenhouse gases are climbing, a trend that shows little sign of abating. This reality has prompted some scientists to seriously consider the prospects of geoengineering. In a new modeling study looking at the consequences of geoengineering gone awry, Jones et al. found that the sudden termination of a large‐scale geoengineering project could drive half a century's worth of warming in just a few years.
