 In their Explore Series lecture, scientists Dr. Yaga Richter from NCAR and Dr. Doug McMartin from Cornell University discussed turning down the thermostat, climate intervention using stratospheric aerosols. In his presentation, we're going to talk about climate intervention research utilizing stratospheric aerosols, and we're going to talk about only modeling studies that utilize the community Earth system model, which is one of the world's best Earth system models. We hope that we can manage climate change simply by cutting emissions, but if we can't, we may need to think about other ideas on how we can cool the planet and reduce climate impacts. Natural analog for this is volcanic eruptions. That puts material up into the stratosphere that cools the planet. Those natural analogs prove that the idea works. It's a very complex problem, and we are very uncertain what the regional changes associated with climate intervention might be. We need lots of scientists from different areas to study the topic, as it really is a whole Earth system problem.
