Temperature and Precipitation Responses to a Stratospheric Aerosol Geoengineering Experiment Using the Community Climate System Model 4
Open accessAbstract
As the global climate continues to change it may become critical to explore possibilities for climate intervention and remediation to counteract warming by greenhouse gases. One such ‘geoengineering solution’ proposes to inject reflective aerosol particles into the atmosphere to decrease insolation, the amount of radiation coming from the sun received by the Earth. Given constraints due to a lack of technology and restricted physical experimentation, we study the unintended potential consequences of this experimental solution by examining the temperature and precipitation response to historical scenarios, projected radiative forcing, and idealized geoengineering scenarios to counteract radiative forcing due to human influences, using the Community Climate System Model version 4, CCSM4. The model projects increased temperature globally, increased precipitation in the Tropical Pacific, and decreased precipitation in some semi-arid regions if climate change continues without mitigation. Although these changes are not as severe with geoengineering, global temperature and precipitation are still redistributed globally. This research helps to understand the possible effects of geoengineering on the radiative balance affecting the Earth’s temperature and hydrologic cycle.

The paper’s Summary describes a JEI study of climate change and geoengineering, so it supports citing this article as an example of climate-related research. Neither the Summary nor the passages retrieved about classroom use report that the article was used successfully to supplement high-school climate education; the high-school affiliation and pre-college internship do not establish classroom use.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
