Adding to the Everything-Causes-Global -Warming file comes the nuttiest idea yet! Researchers have used computer modelling to show plants actually cause global warming. The research shows surprise,surprise,that the contribution of CO2 to Global Warming is "worse than we thought". I think that alarmist keyboards have those four words on a function key for fast retrieval.
Plants take carbon dioxide (CO2) out of the atmosphere to do photosynthesis, and thus help reduce the greenhouse gases warming the planet. At least, that’s how the story went before researchers from the Carnegie Institution for Science (CIS) realized that the today’s carbon dioxide levels cause the plants to behave in a way that actually contributes to global warming.
Writing in the latest issue of the journal Proceedings of the National Academy of Science, the CIS scientists unveiled new research that shows increased carbon levels cause plants to retain water that otherwise would have evaporated from their leaves, entered theatmosphere and helped cool the planet. At local levels, this effect can increase the temperature to be 25 percent more than what the greenhouse effect would have done on its own.
“There is no longer any doubt that carbon dioxide decreases evaporative cooling by plants and that this decreased cooling adds to global warming,” said Long Cao, a CIS scientist and study coauthor . “This effect would cause significant warming even if carbon dioxide were not a greenhouse gas.”
Of course we now need and have been given a new climate computer model to rectify any minute inaccuracies in the old ones.
Most climate models don’t take the cooling effect of this escaped plant water into account, so the CIS researchers generated new climate models based on their understanding of this phenomenon.
The new model showed that, averaged over the entire globe, the loss of released plant water accounts for 16 percent of warming of the land surface, with greenhouse effects accounting for the rest. But in some regions, such as parts of North America and eastern Asia, the effect can account for more than 25 percent of the total warming.
Unfortunately, these results don’t just confirm that the contribution of CO2 to global warming is worse than scientists previously thought, but also greatly complicate any attempts to reverse the warming process.
Somewhere,sometime' these loons in white coats will have to learn that not every single natural process in this world has to be related to Global Warming and some things just are!
