Daniel P. Schrag
From Wikipedia, the free encyclopedia
Daniel P. Schrag is the Professor of Earth and Planetary Sciences and Director of the Laboratory for Geochemical Oceanography at Harvard University. He co-wrote the Snowball Earth with his Harvard colleague Paul F. Hoffman.
In 2004, President Lawarence Summers selected Prof. Schrag to direct the Harvard University Center for Environment.
Dr. Schrag is well known for his work constructing geologic temperature records with deep marine sediments and corals. He is also known for working on a wide variety of scienctific issues from the paleo-climate history of Mars to engineering solutions to anthopogenic climate change. His recent work wih Kurt Zenz House (Harvard University) and Charles Harvey (MIT) on storing captured CO2 as dense liquid and solid hydrate in deep ocean sediments has been widely discussed.
In February of 2007, Dr. Schrag published a perspective in Science Magazine titled, "Preparing to Capture Carbon." In that article, Dr. Schrag advocates a large scale effort to prepare the world to capture carbon dioxide from large point sources and store the CO2 in various geologic repositories.
