...that now, some of the extra atmospheric carbon–raw material for photosynthesis--may be feeding back into living plants and making them grow faster. "The extra carbon dioxide in the atmosphere may be providing a fertilizing effect" said study coauthor Timothy Hall, a senior scientist at NASA's Goddard Institute for Space Studies...

...said David Biddinger, tree fruit entomologist and biocontrol specialist at the Penn State Fruit Research and Extension Center in Biglerville. "When the numbers of mites per leaf reaches 25 to 30, the tree becomes stressed and the leaves start to bronze. This affects the quality of its fruit and in two to three seasons can actually kill small trees."
