Global Warming and Earth's Shrinking Atmosphere

Climate Change Affecting Earth's Outermost Atmosphere
December 11, 2006

BOULDER—Carbon dioxide emissions from the burning of fossil fuels will produce a 3 percent reduction in the density of Earth's outermost atmosphere by 2017, according to a team of scientists from the National Center for Atmospheric Research (NCAR) and The Pennsylvania State University (PSU). The research, which appears in the latest issue of Geophysical Research Letters, will be presented today at the annual meeting of the American Geophysical Union.

"We're seeing climate change manifest itself in the upper as well as lower atmosphere," says NCAR scientist Stan Solomon, a co-author of the study. "This shows the far-ranging impacts of greenhouse gas emissions."
