Daniel Paul Schrag (born January 25, 1966) is the Sturgis Hooper Professor of Geology, Professor of Environmental Science and Engineering at Harvard University and Director of the Harvard University Center for the Environment.
[2] With John Marshall, he co-founded The Potential Energy Coalition, an environmental NGO aimed at deploying more effective communication strategies around climate change.
With Eric Love, he co-founded The Carbon Endowment, an environmental NGO aimed at acquiring underground coal reserves and conserving them in perpetuity.
[4] Much of his early research focused on reconstructing past climate change, including work on a deep sea sediments from the Cretaceous and early Cenozoic; theories for Pleistocene ice-age cycles, including a new way of reconstructing deep ocean temperature and salinity using pore fluids; and reconstructing tropical climate variability from geochemical variations in corals and trees.
His interest in modern and future climate change led to a focus on technological approaches to mitigating future climate change, including work on carbon capture and storage (CCS), low-carbon options for transportation fuels, and a wide variety of other issues in energy technology and policy including direct air capture of carbon dioxide.
