Neelin is a professor of atmospheric and oceanic sciences and an expert on global climate patterns and climate modeling. An atmospheric physicist, he contributed to reports by the United Nations Intergovernmental Panel on Climate Change and the National Research Council on ocean-atmosphere-land interactions affecting climate.
Tripati is an assistant professor of Earth, planetary and space sciences who reconstructs Earth’s ancient climate record to discover the long-term effects of atmospheric carbon dioxide, a key contributor to global climate change. Based on techniques Tripati helped develop, she and her colleagues have been able to study carbon dioxide levels over the last 20 million years.
Hall is a professor of atmospheric and oceanic sciences and an expert on climate modeling, the mechanisms that govern Earth’s climate and the planet’s sensitivity to historical increases in greenhouse gas emissions. An atmospheric physicist, he contributed to the United Nations Intergovernmental Panel on Climate Change report.
