And she happened to point out some very current and needed studies
on ozone damage to plants.
It's easy to find a number of success stories on the power of political decisions as the industry has opposed using economic arguments also changes that have been easy to make (like some required changes for cars) or that did indeed allow for rapid technology development as reduction of sulfur emissions or replacement
of ozone damaging chemicals by safer ones.
They used to be chlorofluorocarbons (CFC) that were banned for damaging the ozone layer, and were replaced by HFCs don't
cause ozone damage, but are more than a thousand times worse than CO2 as greenhouse gases.
«We also welcome EPA's proposal of a separate standard to protect forests
from ozone damage,» Baron said.
Now, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have identified an aerosol for solar geoengineering that may be able to cool the planet while simultaneously
repairing ozone damage.
In contrast, the tropics, already warm, do not benefit from further warming, but they are not as hard hit by
ozone damage because ozone - precursor emissions are lower in the tropics.
«The increased risk
of ozone damage to vegetation is mainly due to rising ozone concentrations and higher temperatures in the future,» says Jenny Klingberg at the University of Gothenburg's Department of Plant and Environmental Sciences.
Once miraculous, chlorofluorocarbons that
caused ozone damage are now helping scientists track its effects on the Southern Ocean.
According to the letter, Headline was relabeled to say its «benefits may include improved host plant tolerance to yield - robbing environmental stresses, such as drought, heat, cold temperatures, and
ozone damage» as well as bacterial and viral infections.
Neutralizes free radicals on the upper layer of the skin to help prevent the impact of
ozone damage to skin
Another difference between global warming and
ozone damage was the iconic nature of the ozone problem.
Many scarcely distinguished among climate change from greenhouse warming,
ozone damage from CFCs, and health threats from automobile tailpipes and power plant smokestacks.
Klingberg said: «The results show that the risk of
ozone damage to plants is greatest in central Europe where ozone concentrations are high and climatic conditions promote uptake of ozone through the stomata.
