James’ publications

Always under development, last updated Sept 2017. A complete but older (2013) version of my web page dating to my time in Japan can be found here, which is no longer maintained. I’m slowly working through this page adding links to the older papers, and also updating with new ones as they come in.

H-index: the “official” Web of Science number was about 23 last time I checked, google scholar is more generous with 31. Ok, I admit it, I checked and updated these numbers when I last edited this page.

topics – climate change, ensemble methods/uncertainty, paleoclimate
