Global warming could make your pollen allergies a lot worse

new study suggests that various pollen and grass allergies could get much worse due to the higher greenhouse gas concentrations that result from global warming.  In this study, the effects of elevated levels of CO2 (carbon dioxide) and O3 (ozone) on Timothy grass (Phleum pratense L.) were examined.  Researchers found that elevated levels of CO2 increased the amount of grass pollen produced by ~50% per flower.  The net effect of CO2 and O3 indicated that increased allergen exposure occurred under elevated levels of both greenhouse gases.  Better stock up on Reactine..
