Sigh. All in the mind. I wonder if they assumed an increase in magic unicorns also and fed that into the supercomputer? Disgraceful waste of effort, money and computer time.

Watts Up With That?

New research indicates that the pollution may worsen in coming decades due to chemical reactions in the air associated with climate change. (Wikimedia photo by Thomas.)

From UCAR:  BOULDER—Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new research led by the National Center for Atmospheric Research (NCAR). The detailed study shows that Americans face the risk of a 70 percent increase in unhealthy summertime ozone levels by 2050.

This is because warmer temperatures and other changes in the atmosphere related to a changing climate, including higher atmospheric levels of methane, spur chemical reactions that lead to ozone.

Unless emissions of specific pollutants that are associated with the formation of ozone are sharply cut, almost all…
