As inventors of all varieties race to develop the magic eco-fuel, the best ion battery or the most effective solar collection system, geologists are quietly exploring how certain types of rocks absorb our human carbon emissions.

According to a new article in the journal Global Change Biology, a team led by Michigan Tech forestry professor David F. Karnosky has established that increased levels of atmospheric CO2 “act directly to delay the usual autumn spectacle of changing colors and falling leaves in northern hardwood forests.”
