An overwhelming quantity of direct observations and analyses published by scientists in various disciplines around the world demonstrates that human activity has warmed the planet and altered the climate. The severity of the projected impacts of continuing on our current greenhouse gas emissions path has only increased in recent years.
Please join the Center for American Progress for an educational event featuring two respected scientists who have both helped author reports produced by the Intergovernmental Panel on Climate Change. Dr. Michael MacCracken and Dr. Christopher Field will explain the IPCC’s assessment process, how we know what we know about human-caused climate change, what we have learned since the 2007 IPCC report, and why the science must inform public policy in the United States.
Christopher Field, Director, Department of Global Ecology, Carnegie Institution of Washington, and Professor of Biology and Environmental Earth System Science at Stanford University, and a coordinating lead author for the IPCC’s Fourth Assessment
Michael MacCracken, Chief Scientist for Climate Change Programs, Climate Institute, and co-author/contributing author for various chapters in the IPCC assessment reports
