Several independent rating services ranked Gerrard as the leading environmental lawyer in New York and one of the leading environmental lawyers in the world.
James Hansen is director of NASA’s Goddard Institute for Space Studies. He is also an adjunct professor in the Department of Earth and Environmental Sciences at Columbia University. Hansen has studied global surface temperatures and the earth’s atmosphere since the 1970s,with a particular focus on the development and application of global numerical models to understand climate trends and the impact of human activities on climate. Recently Hansen has spoken out against government censorship of climate science.
Geoffrey Heal is the Garrett Professor of Public Policy and Corporate Responsibility at the Graduate School of Business at Columbia University. He is also the executive director of Columbia’s Center on Globalization and Sustainable Development. Heal’s research focuses on the interface between economics and ecology and the extent to which profit-oriented companies can contribute to the solution of social and environmental problems. His most recent book, When Principles Pay: Corporate Social Responsibility and the Bottom Line, was published in 2008.
Patrick Kinney is associate professor of environmental health sciences at Columbia’s Mailman School of Public Health (MSPH) and director of the Program on Climate and Health. Kinney’s teaching and research address issues at the intersection of global environmental change, human health and policy, with an emphasis on the public health impacts of air pollution. At MSPH, he heads an interdisciplinary research and teaching program on the human health impacts of climate variability and change.
Klaus Lackner is the Ewing-Worzel Professor of Geophysics, the director of the Lenfest Center for Sustainable Energy (LCSE) and chair of the Department of Earth and Environmental Engineering in the School of Engineering and Applied Sciences.

Gisela Winckler is a Doherty Associate Research Scientist at the Lamont-Doherty Earth Observatory at Columbia University. Winckler uses interplanetary dust found in sediment cores to get a clearer picture of the earth’s geology and climate hundreds of thousands of years ago. Her reconstruction of past climates is key to understanding the climate system’s sensitivity to natural variability and anthropogenic, or human-induced, perturbations.
