Royer Co-Authors Important CO2 Study

Dana Royer, assistant professor of earth and environmental sciences, contributed to an important study on the dangerous levels of Carbon Dioxide on the planet. He is featured in a Nov. 6 issue of Health News Digest. According to the article, if climate disasters are to be averted, atmospheric carbon dioxide (CO2) must be reduced below the levels that already exist today. The model, created by Royer and nine other scientists from the U.S., the U.K. and France, suggests “the only realistic way to sharply curtail CO2 emissions is phase out coal use except where CO2 is captured and sequestered.” According to the study, coal is the largest source of atmospheric CO2 and the one that would be most practical to eliminate. The study was presented in the Open Atmospheric Science Journal, Volume 2, 217-231, published in 2008.
