As a philosopher of science, my projects involve conceptual and foundational issues in climate science.I am currently working on two projects.
The first is untangling what is meant by “Added value” in Regional Climate modeling, and what it can mean in relation to global climate models, where I am working with Linda Mearns and Melissa Bukovsky. My second project is a co-authored piece with Naomi Oreskes, analyzing the Detection and Attribution research community’s responses to Kevin Trenberth’s efforts to get them to change their starting assumptions when they analyze extreme events; what are their null hypotheses, or their priors? Why do they demonstrate so much resistance to Trenberth et al.’s suggestion in June 2015 to privilege the thermodynamic parts of the models in order to establish that there is, indeed, a climate change influence on the extreme event under scrutiny? These are all very philosophical disagreements the climate scientists are having, so they are fascinating and fun for a philosopher to analyze.
