Short summary
Carbon dioxide (CO2) levels are increasing in the atmosphere. CO2 has a direct fertilization effect on plants, meaning that plants can photosynthesize more and create more biomass under higher atmospheric CO2. This paper outlines the first direct evidence of a carbon fertilization effect on plants in Earth's past from 23 × 106 yr old fossil leaves, when CO2 was higher. This allowed the biosphere to extend into areas that are currently too dry or too cold for forests.
