You are skimming when you need to read carefully.<br /><br />The solution remains to stop burning fossil fuels.<br /><br />"The chemical known as ozone may be making a much more significant contribution to global warming than scientists had previously thought, according to a new study published in the journal Nature.<br /><br />"Ozone could be twice as important as we previously thought as a driver of climate change," said study co-author Peter Cox.<br /><br />Ozone occurs naturally in the upper atmosphere, but is produced in the lower atmosphere when sunlight strikes industrial pollutants such as carbon dioxide, methane and nitrogen oxides.<br /><br />Scientists have long known that ozone is a greenhouse gas, trapping radiation within the atmosphere and leading to rising global temperatures. But the new study suggests that ozone may have a much more significant climate impact by adversely affecting plants' ability to remove carbon dioxide from the atmosphere.<br /><br />According to the researchers, high concentrations of ozone and carbon dioxide damage plants' ability to engage in photosynthesis. This weakens the plants, causing their stomata (pores in the leaves) to close. In turn, this reduces that amount of carbon dioxide or ozone that the plants are able to absorb."<br /><br />from http://membrane.com/global_warming/notes/ozone_chokes.htmlGail Zawackihttps://www.blogger.com/profile/01800944469843206253noreply@blogger.comtag:blogger.com,1999:blog-5549306427964459740.post-57867348955661338262009-07-30T18:06:39.527-04:002009-07-30T18:06:39.527-04:00Now that the cause of the tree's distress is k...Now that the cause of the tree's distress is known to be ozone and not climate change, what steps can be taken to reduce ozone?Paul Kellyhttp://replacefossil.comnoreply@blogger.com
