Could the hazy days of summer actually help keep down global warming? Well the surprising answer may be yes, according to an article by climatologist Dr. Robert Balling. Balling explains that much of the haze we see in summer comes from trees which emit a tremendous amount of hydrocarbons. Recent studies in Canada revealed that heavy concentrations of these aerosols weaken incoming solar radiation, thus having a cooling effect. Beyond that, hydrocarbons also produce more clouds, which slow down any warming. Since trees all over the world grow even faster and bigger with higher levels of carbon dioxide, Balling suggests our planet may actually be clever enough to stop any harmful warming effects from the earth’s most intelligent creatures — namely, people.
