CO2 worsens wildfires by helping plants grow

A recent study by the University of California - Riverside found that carbon dioxide is driving an increase in the severity and frequency of wildfires by fueling the growth of plants that become kindling. This process occurs because plants use the extra CO2 to make carbohydrates, leading to an increase in biomass that burns.
