Michael Mann is a distinguished professor of atmospheric science and director of the Earth System Science Centre at Pennsylvania State University. A climatologist and geophysicist, he is a leading contributor to the IPCC and is widely regarded as one of the world's leading climate scientists. His work has been pivotal in advancing our understanding of humanity's influence on global temperatures, notably through the famous “hockey stick graph” outlining the earth's temperature over the past millennium.  An outspoken defender of the scientific process and academic freedoms, his work also focuses on climate change denialism, reflected in his most recent book The Madhouse Effect: How Climate Change Denial Is Threatening Our Planet, Destroying Our Politics, and Driving Us Crazy (2016). He is a contributor to numerous publications including The Guardian and the Washington Post and documents the impact of climate change on current events in RealClimate.org. In this interview, Michael discusses the overwhelming scientific consensus on man-made climate change. He outlines some of the effects a warming planet could have in the future and through reference to recent extreme weather events — how climate change is already being felt in real time. Michael addresses climate change denialism, particularly the influence of “fake news,” and public disinformation campaigns that have helped turn climate science into a politically contentious topic. Michael also provides words of warning regarding geoengineering and stresses the primary need to reduce emissions whilst the carbon budget remains. He ends on a note of cautious optimism, stressing the success of the Paris Agreement, providing a blueprint to curb emissions, and how initiatives at the municipal and state level can help the United States' commitment to the accord, regardless of the political administration in the US.

RealClimate.org The Solutions Project  Skeptical Science Solutionary Rail   Guests: Michael Mann is Distinguished Professor of Atmospheric Science at Penn State University, with joint appointments in the Department of Geosciences and the Earth and Environmental Systems Institute (EESI). He is also director of the Penn StateEarth System Science Center (ESSC). Dr. Mann received his undergraduate degrees in Physics and Applied Math from the University of California at Berkeley, an M.S. degree in Physics from Yale University, and a Ph.D. in Geology & Geophysics from Yale University. His research involves the use of theoretical models and observational data to better understand Earth’s climate system. Dr. Mann was a Lead Author on the Observed Climate Variability and Change chapter of the Intergovernmental Panel on Climate Change (IPCC) Third Scientific Assessment Report in 2001 and was organizing committee chair for the National Academy of Sciences Frontiers of Science in 2003. He has received a number of honors and awards including NOAA’s outstanding publication award in 2002 and selection by Scientific American as one of the fifty leading visionaries in science and technology in 2002. He contributed, with other IPCC authors, to the award of the 2007 Nobel Peace Prize. He was awarded the Hans Oeschger Medal of the European Geosciences Union in 2012 and was awarded the National Conservation Achievement Award for science by the National Wildlife Federation in 2013. He made Bloomberg News’ list of fifty most influential people in 2013. In 2014, he was named Highly Cited Researcher by the Institute for Scientific Information (ISI) and received the Friend of the Planet Award from the National Center for Science Education. He is a Fellow of the American Geophysical Union, the American Meteorological Society, and the American Association for the Advancement of Science. Dr. Mann is author of more than 190 peer-reviewed and edited publications, and has published two books including Dire Predictions: Understanding Climate Change and The Hockey Stick and the Climate Wars: Dispatches from the Front Lines. He is also a co-founder of the award-winning science website RealClimate.org. Mark Z. Jacobson is a Professor of Civil and Environmental Engineering at Stanford University where he is also Director of the Atmosphere/Energy Program. He is a Senior Fellow for both the Woods Institute for the Environment and the Precourt Institute for Energy. He received a B.S. in Engineering, a B.A. in Economics and an M.S. in Environmental Engineering from Stanford University. He received an M.S. and a PhD in Atmospheric Science from UCLA. The main goal of Jacobson’s research is to understand better severe atmospheric problems, such as air pollution and global warming, and develop and analyze large-scale clean-renewable energy solutions to them. To address this goal, he has developed and applied three-dimensional atmosphere-biosphere-ocean computer models and solvers to simulate air pollution, weather, climate, and renewable energy. In 1993-4, he developed the world’s first computer model to treat the mutual feedback to weather and climate of both air pollution gases and particles, and in 2001, the first coupled air-pollution-weather-climate model to telescope from the global to urban scale. In 2000, he applied this model to discover that black carbon, the main component of soot pollution particles, might be the second-leading cause of global warming in terms of radiative forcing, after carbon dioxide. This and subsequent papers provided the original scientific basis for several laws and regulations on black carbon emission controls worldwide. His findings that carbon dioxide domes over cities and carbon dioxide buildup since preindustrial times have enhanced air pollution mortality through its feedback to particles and ozone served as a scientific basis for the Environmental Protection Agency’s 2009 approval of the first U.S. regulation of carbon dioxide (the California waiver). With respect to solvers, in 1993, he developed the world’s fastest ordinary differential equation solver in a three-dimensional model for a given level of accuracy. He subsequently developed solvers for cloud and aerosol coagulation, breakup, condensation/evaporation, freezing, dissolution, chemical equilibrium, and lightning; air-sea exchange; ocean chemistry; greenhouse gas absorption; and surface processes. With respect to energy, in 2001 he published a paper in Science examining the ability of the U.S. to convert a large fraction of its energy to wind power. In 2005, his group developed the first world wind map based on data alone. His students subsequently published papers on reducing the variability of wind energy by interconnecting wind farms; on integrating solar, wind, geothermal, and hydroelectric power into the grid; and on wave power. In 2009, he coauthored a plan, featured on the cover of Scientific American, to power the world for all purposes with wind, water, and sunlight (WWS). In 2010, he appeared in a TED debate rated as the sixth all-time science and technology TED talk. In 2011, he cofounded The Solutions Project, a group that combines science, business, and culture to develop and implement science based clean-energy plans for states and countries. In 2013, his group developed individual WWS energy plans for each of the 50 United States. To date, he has published two textbooks of two editions each and ~150 peer-reviewed journal articles. He has testified three times for the U.S. Congress. Nearly a thousand researchers have used computer models he has developed. In 2005, he received the American Meteorological Society Henry G. Houghton Award for “significant contributions to modeling aerosol chemistry and to understanding the role of soot and other carbon particles on climate.” In 2013, he received an American Geophysical Union Ascent Award for “his dominating role in the development of models to identify the role of black carbon in climate change” and the Global Green Policy Design Award for the “design of analysis and policy framework to envision a future powered by renewable energy.” In 2016, he received a Cozzarelli Prize from the Proceedings of the National Academy of Sciences for “outstanding scientific excellence and originality” in his paper on a solution to the U.S. grid reliability problem with 100% penetration of wind, water, and solar power for all purposes. He has also served on the Energy Efficiency and Renewables advisory committee to the U.S. Secretary of Energy and was invited to talk about his world and U.S. clean-energy plans on the Late Show with David Letterman.

Geophysicists David Archer and Raymond Pierrehumbert provide a joint perspective on rising CO2 levels in the atmosphere and their expected impact on the earth's climate. It's more than just a question of magnitude--this talk will address just how long (in geological terms) increased emissions will impact the planet's temperature, rainfall, sea level, and ice coverage. What are the ethical implications and economic arguments? Speaking from decades of research, Archer and Pierrehumbert will offer their thoughts on these questions and critique the thinking of some mainstream economists on climate change.Recommended reading:Climate Change: A Catastrophe in Slow Motion; RealClimate.org; The Long Thaw: How Humans are Changing the Next 100,000 Years of Earth's Climate; The millennial atmospheric lifetime of anthropogenic CO2; and Warming Papers (soon to be released by Blackwell/Wiley Press)

For the scientists who study global warming, now is the winter of their despair.   In the news, it has been climate scandal after alleged climate scandal.  First came “ClimateGate,” then “GlacierGate,” “Amazon Gate,” and so on.  In public opinion polls, meanwhile, Americans’ acceptance of the science of global warming appears to be declining.  Even a freak snowstorm now seems to sow added doubt about this rigorous body of research.   In response to growing public skepticism—and a wave of dramatic attacks on individual researchers—the scientific community is now bucking up to more strongly defend its knowledge.  Leading the charge is one of the most frequently attacked researchers of them all—Pennsylvania State University climatologist Michael Mann.   In this interview with host Chris Mooney, Mann pulls no punches.  He defends the fundamental scientific consensus on climate change, and explains why those who attack it consistently miss the target.  He also answers critics of his “hockey stick” study, and explains why the charges that have arisen in “ClimateGate” seem much more smoke than fire.   Dr. Michael E. Mann is a member of the Pennsylvania State University faculty, and director of the Penn State Earth System Science Center.  His research focuses on the application of statistical techniques to understanding climate variability and change, and he was a Lead Author on the “Observed Climate Variability and Change” chapter of the Intergovernmental Panel on Climate Change (IPCC) Third Scientific Assessment Report.  Among many other distinguished scientific activities, editorships, and awards, Mann is author of more than 120 peer-reviewed and edited publications.  That includes, most famously, the 1998 study that introduced the so called “hockey stick,” a graph showing that modern temperatures appear to be much higher than anything seen in at least the last thousand years.  With his colleague Lee Kump, Mann also recently authored the book Dire Predictions: Understanding Global Warming.  Finally, he is one of the founders and contributors to the prominent global warming blog, RealClimate.org.
