The Sky Is Rising

Makarand writes "The height of the tropopause, the boundary layer between the troposphere and stratosphere and the roof of the Earth's lower atmosphere, has risen by an average of around 650 feet globally over the last 22 years according to this article in the San Francisco Chronicle. Greenhouse gases trap infrared radiation and warm the troposphere. The resulting tropospheric expansion is moving the tropopause upward. Also, the ozone depleted stratosphere is losing its ability to absorb sunlight causing it to cool and contract pulling the tropopause upward."
