Climate Engineering: Benefits, Side-Effects, Risks, and Opportunities

Dr. Simone Tilmes

Atmospheric Chemistry Observations & Division, NCAR

Climate Engineering has been proposed to counteract the effects of climate change. There are two types of climate engineering, one that actively removes carbon dioxide from the atmosphere and therefore addresses increasing greenhouse gases directly, and the other, that attempts to reduce incoming solar radiation to directly cool the Earth’s surface, also called solar radiation management (SRM). In this seminar, research on one of the more prominent methods of SRM is presented, the reduction of incoming solar radiation via stratospheric aerosol modifications. This approach has been widely discussed in recent years and various climate model studies have been performed to understand impacts and efficiency of a potential application. I will discuss potential benefits, side effects and risks of stratospheric aerosol modification approaches. There are many reasons why SRM may not be a good idea. However, continued increase of surface temperatures will likely lead to warming above certain targets and SRM in addition to aggressive mitigation may help reduce suffering as a result of climate change and potentially avoid reaching tipping points. I will outline how well-designed sulfur injection strategies may be a game-changer in climate engineering research.
