The Geoengineering Model Intercomparison Project

http://climate.envsci.rutgers.edu/GeoMIP

The Geoengineering Model Intercomparison Project (GeoMIP) was borne out of a need to robustly understand climate model response to geoengineering. At the time of its inception, several geoengineering studies had been performed with several different climate models, but each modeling group had done their simulations in a slightly different way, so it was hard to understand why the results were different. In 2010, Andy Jones led a study (in which I was involved) where two groups happened to do similar enough geoengineering experiments to be compared directly. This was the first true model intercomparison of geoengineering. In some cases, the models showed similar responses to geoengineering, and in other cases, the responses were different, so it was difficult to understand why the models were getting different answers.

These difficulties prompted Alan Robock and myself to draft a proposal to the climate modeling community, trying to get everyone to perform the same experiments. We settled on four experiments, detailed in a publication I led. And thus GeoMIP was born. Since then, we have had numerous successes, including a special issue in Journal of Geophysical Research of 15 publications and four international meetings. Our results were present in Chapter 7 of Working Group 1 of the IPCC's Fifth Assessment report and in the report on geoengineering from the National Research Council.

Climate Engineering Conference 2017

I am serving on the steering committee for this conference, which will be held in late summer, 2017 in Berlin, Germany.

Climate Engineering Conference 2014

http://www.ce-conference.org

Climate engineering is rapidly becoming a contentious issue within political, scientific, and cultural discussions of climate change, in part due to a perceived lack of progress on crucial emission reductions. By organizing a large conference, we strive to engage in critical global discussions by bringing together the research, policy, and civic communities to discuss the highly complex and interlinked ethical, social and technical issues that come into focus when discussing climate engineering. I am serving on the steering committee for this conference, which was held 18-21 August 2014 in Berlin, Germany.
