Welcome!

This is Jonah Bloch-Johnson's homepage. I'm a PhD student at the University of Chicago's Department of Geophysical Sciences, where I study cloud feedbacks and other potential sources of nonlinear behavior in response to increased CO2 radiative forcing (aka, global warming) with Ray Pierrehumbert. My climate related work is here.

I was previously CEO and co-founder of Almanac Environmental Services, Inc., a software company which gave consumers the data they needed to wield their purchasing power ethically. For more on our work, click here.
