Photorespiration may increase, leading to a decrease in photosynthetic production of sugar.

The graph shows records of temperature (light gray line) and CO2 (dark gray line) over the past 1,000 years. CO2 is recorded in parts per million (ppm).


If the trends shown in the graph continue, how might this affect photosynthesis?
