They do grow more quickly, but their leaves are thinner and lacking in flavor (nutrients). It's pretty easy to spot the produce in the grocery store that comes from greenhouses.<br /><br />The long-term consequences for trees that live for many years of higher levels of CO2 could be the same as the long-term consequences of elevated caloric uptake for people - health issues like diabetes and heart disease.Gail Zawackihttps://www.blogger.com/profile/01800944469843206253noreply@blogger.comtag:blogger.com,1999:blog-5549306427964459740.post-75463299556230422282010-08-24T19:11:11.934-04:002010-08-24T19:11:11.934-04:00I saw this comment at Kevin Drum and thought you m...I saw this comment at Kevin Drum and thought you might be interested<br /><br /> <br />Eric Worrall Today 11:10 AM<br />Farmers use elevated CO2 levels to boost production in Greenhouses, so the reduction in update of CO2, if any, cannot be due to any increase in CO2 levels.<br /><br />There is another possibility. The sun is unusually quiet at the moment. Its been known for centuries, ever since the decadal solar cycle was correlated with food prices, that the solar cycle has a significant impact on food production, with a quiet sun being bad. The periods of low solar activity in medieval times were detected by, among other things, examing records for evidence of periodic changes in grain prices.<br /><br />http://www.bioedonline.org/news/news.cfm?art=686<br /><br />Reduced plant growth due to the extended period of low solar activity could explain a reduced uptake of CO2.<br /><br />catmanAnonymousnoreply@blogger.com
