It seems we’ve discovered one more confounding factor to an accurate appraisal of climate change. As reported in the NCPA’s Daily Policy Digest, researchers at the Met Office Hadley Centre in England believe that efforts in the U.S. and around the globe to improve air quality are contributing to greater numbers of tropical storms. Climate simulations (that is historical backcasting using climate models) indicate that as aerosols have decreased due to technological innovation and clean air laws, has increased tropical storm activity.
This is a bit curious since actual storm counts show no increase outside of the natural range of variability. Could this be another instance of model bias ― the bias of climate models to predict bad results whatever the change in inputs?
The more we know, the clearer it becomes that we don’t know that much about the climate.
