RS93 - Dr. Michael E. Mann On The Science Of Climate Change

Release date: September 29, 2013

Michael E. MannIn this episode of Rationally Speaking, Julia and Massimo talk to physicist and climatologist Michael Mann about how we know the climate is getting warmer. Among other things, they cover the physical processes of climate change, the role that predictive models have played in confirming scientists' theories about the rate of warming, and what are uncertainties in the science. Also, how optimistic we should be about technological solutions to the problem.

Dr. Michael E. Mann is Distinguished Professor of Meteorology at Penn State University, with joint appointments in the Department of Geosciences and the Earth and Environmental Systems Institute. He is also director of the Penn State Earth System Science Center. Dr. Mann is author of more than 160 peer-reviewed and edited publications, and has published two books including Dire Predictions: "Understanding Global Warming" in 2008 and "The Hockey Stick and the Climate Wars: Dispatches from the Front Lines" in 2012. He is also a co-founder and avid contributor to the award-winning science website

As always, I enjoyed the podcast. But I wish there will be a guest less podcast soon. I just enjoy the conversations between Julia and Massimo. I really missed Julia in this episode as she did not say much.

Another gripe I have with this episode that Massimo, as a former biologist, did not point out the obvious, safest and the most beneficial way of sequestering carbon from the atmosphere: increasing tree and vegetation cover in degraded, deforested and farm lands. The current carbon loading of the atmosphere is due to the release of carbon sequestered by plants alive millions/billions (I am not sure if it takes million or billions of years for biomass to turn to fossil fuel). Deforestation and emission from agriculture continue to be major sources of GHG emissions currently. So I think plant based sequestration is still a much better and safer solution than geo-engineering. They also have potential for creating more habitat for wild life and livelihood opportunities for the rural poor around the world.

"The outer boundary of what we currently believe to be feasible is still far short of what we actually must do". --Al Gore on global warming from his Nobel Peace Prize acceptance speech

If Mr. Gore is right, "What we actually must do" is indeed WELL beyond "The outer boundary of what we currently believe to be feasible." Even then, that was an estimated 80% reduction in "greenhouse gases" by 2050.

There's something relatively simple from outside the box that would help a lot, but would require profitable grass roots participation -- governments simply aren't going to do squat.

What percentage of the greenhouse effect derives from water vapor?

Perhaps we should implement a worldwide Hydrocarbon Fuel Tax.
