Experts from the Met Office, the University of Exeter and the Centre
for Ecology & Hydrology, have found that projections of increasing
ozone near the Earth's surface could lead to significant reductions in
regional plant production and crop yields. Surface ozone also damages
plants, affecting their ability to soak up carbon dioxide from the
atmosphere and accelerating global warming.
Near-surface ozone has doubled since 1850 due to chemical emissions
from vehicles, industrial processes, and the burning of forests.
