Ken Caldeira

Climate Scientist, Carnegie Institution for Science, Department of Global Ecology at Stanford University

Ken Caldeira is a climate scientist at the Carnegie Institution for Science, where his job is “to make important scientific discoveries.” He investigates issues related to climate, carbon, and energy systems. His primary tools are climate and the carbon cycle models, although he does field work related to ocean acidification. Caldeira is also a contributing author to the Intergovernmental Panel on Climate Change AR5 report "Climate Change 2013: The Physical Science Basis." Professor Caldeira has a wide-spectrum approach to analyzing the world’s climate systems.

Caldeira received his B.A. from Rutgers College and both his M.S. (1988) and Ph.D. (1991) in atmospheric sciences from New York University.
