Climate change will make more ozone is dangerous to plants

Ground-level ozone is a pollutant of the atmosphere, harming both people and plants, and a huge influence on the extent of damage have the climate and weather. Researchers from the University of Gothenburg (Sweden) showed that by the end of the century, climate change can significantly increase the effects of ozone on plants of North and Central Europe.

"The most important effects of rising temperatures — premature aging cultures, resulting in lower yields and quality," — said study co-author Jenny Klingberg.

Ozone — atmospheric gas, located at an altitude of 10-40 km. There, the ozone layer protects the Earth's surface from the sun's ultraviolet radiation, which is harmful for all living things. Ozone is also produced near the surface due to the reactions of automobile exhausts by sunlight. Plants more than people who are sensitive to it, absorbing ozone through stomatal openings on the leaves.

Traditionally, the risk of exposure to ozone on plants was calculated on the basis of its concentration in the ambient air. Swedish researchers first showed that warming is not less important factor, because the stomata open wider in the warm weather.

On the other hand, the researchers found that the stomata are already, when increasing the concentration of carbon dioxide. Can this effect play a compensatory role? Exact figures have not been able to get (especially trees), but, according to preliminary data, the effect will be negligible.
