Short summary

The injection of aerosols into the stratosphere to reflect sunlight could reduce global warming, but this type of geoengineering would also impact other variables like precipitation and sea ice. In this study, we model various climate impacts of geoengineering on a 3-D graph to show how trying to meet one climate goal will affect other variables. We also present two computer simulations which validate our model and show that geoengineering could regulate precipitation as well as temperature.
