Volcanoes Caused Ecological Disruption Says Thomas in Nature Article

Ellen Thomas

Ellen Thomas, University Professor in the College of Integrative Sciences and research professor of earth and environmental sciences, is a co-author of a paper titled “Very Large Release of Mostly Volcanic Carbon During the Paleocene-Eocene Thermal Maximum,” published in the weekly science journal Nature on Aug. 31.

The study focused on Palaeocene–Eocene Thermal Maximum, a surface warming event associated with ecological disruption that occurred about 56 million years ago, releasing a large amount of carbon. The researchers combined boron and carbon isotope data in an Earth system model and found that the source of carbon was much larger than previously thought.

Most of the carbon, Thomas and her colleagues discovered, was probably released by volcanism during the opening of the North Atlantic Ocean when Greenland separated from Europe.

The paper also was cited in another Nature article, on PhysOrg and on Science Daily.
