Earth's Atmosphere Is Shrinking

Dotnaught writes: "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 and The Pennsylvania State University. The good news? A thinner atmosphere will mean satellites and space junk can stay in orbit longer due to the reduced drag and rockets will require less fuel to place satellites."
