Recently, Joseph Ortiz, Ph.D., professor and assistant chair in the Department of Geology in Kent State University’s College of Arts and Science, partnered with Sir Roland Jackson, Ph.D., a historian of science at the Royal Institution and the Department of Science and Technology Studies at University College London, to co-author a paper assessing the experiments described in Eunice Foote’s papers from a detailed quantitative perspective and to place them in historical context. They point out the differences between her hypothesis and that of the modern greenhouse effect.

Dr. Joseph D. Ortiz, a professor in the College of Arts and Sciences’ Department of Geology at Kent State University, was part of an international team of researchers that co-authored an article about a deadly tsunami that occurred about 1,000 years ago in Tanzania. The study suggests that the tsunami risk in East Africa could be higher than previously thought.
