Lee Kump PhD – How We Know Increased CO2 is Coming from Humans
August 3, 2015
Last month, I interviewed Geo-Chemist Lee Kump PhD via skype at his office, at Penn State University.
Dr. Kump gave an absolutely terrific mini-seminar on paleoclimate, and I’ve made clips from this an important part of my newest video, which will be posted very soon.
In the clip above, Dr. Kump explains a point that often comes up in climate denial disinformation. Climate deniers are unaware that paleo-scientists have looked long and hard at all the sources of carbon in the atmosphere, and understand quite well that human contributions are responsible for the current build-up of CO2 that is warming the planet.
