Computer analyses of global climate have consistently overstated warming in Antarctica, concludes new research by scientists at NCAR and Ohio State University.

A much-discussed idea to offset global warming by injecting sulfate particles into the stratosphere would have a drastic impact on Earth's protective ozone layer.
