AGU 2013: The importance of 400 ppm CO2

Rather belatedly, Catherine Bradshaw and I wrote a summary of the 400 ppm sessions on the physical science of 400 ppm (Catherine’s session) and on the communication of 400 ppm climate for the Cabot Institute blog.

I don’t have much to add to it, except to say thank you to Catherine, whose original concept it was. Thank you too to Kent and Casey, who were excellent co-convenors.
