Ancient climate expert joins AAAS panel on climate mitigation

UC Davis geoscientist Isabel Montañez will take part in a symposium on how to stabilize global CO2 levels at the annual meeting of the American Association for the Advancement of Science in Vancouver next week.

Montañez’ speciality is in studying the climate of the ancient Earth, both at the time of the emergence of the dinosaurs and more recently in California since the last Ice Age.

One of the major causes of global climate change is the man-made release of the greenhouse gas carbon dioxide (CO2),  primarily from land use changes and fossil fuel consumption. Atmospheric levels of CO2 have increased dramatically since the 1700s and projections are for continued increases throughout the current century, requiring mitigation strategies such as capturing CO2 from power plants and the atmosphere and storing it in reservoirs such as the oceans, geologic formations, and soil and vegetation, a process known as carbon sequestration.

Leading experts on global CO2 cycles and the different methods for carbon sequestration as well as those involved the policy and industry perspectives will gather at the annual meeting of the AAAS at the Vancouver Convention Centre Feb, 17,  to evaluate the various options as well as to propose a path forward. The symposium entitled “Toward stabilization of net global CO2 levels” represents one of the first times that experts in all the various sequestration strategies, along with experts with policy and industry perspectives will participate in a common discussion regarding the appropriateness, the relative strengths, weaknesses, and potential hazards, as well as the economics of the various carbon sequestration methods.

In addition to Montañez, Speakers in the symposium include noted geoscientists ISally Benson (Stanford), and Peter Brewer (Monterey Bay Aquarium Research Institute), biogeochemist/ecologist Keith Paustian (Colorado State University), climate scientists James Hansen (NASA) and César Izaurralde (Joint Global Change Research Institute, Pacific Northwest National Laboratory and University of Maryland), and policy and industry experts Karen Haugen-Kozyra (KHK Consulting, Alberta, Canada) and Benjamin Yamagata (Coal Utilization Research Council).

The symposium is sponsored jointly by the U.S. National Committees of Soil Sciences, Geodesy and Geophysics, Geology, and Quaternary Research (INQUA) of the National Academy of Sciences and was co-organized by the chair of the U.S. National Committee for Soil Sciences, Paul Bertsch (University of Kentucky), and Ester Sztein (National Academy of Sciences).

  1. There is a short video on the home page about IU scientists researching the role of nitrates in groundwater contamination. Can you tell me which scientists or where I could find out more about the research and its conclusions?
