...average of 20-40%. But things get messier when scientists add CO2 to plants growing in real-world conditions. In a set of experiments called the Free-Air Carbon-dioxide Enrichment project, or FACE, investigators have been introducing CO2 into the air in experimental fields and forests around the world. The result is that some plants do grow bigger, says Field, "but an increase in growth doesn't necessarily mean an increase in the plants you want." At Duke University, one of the sites used in the FACE program, he says, "the pine trees grew more, but poison ivy grew...
...their ranges as the climate changes. But as Kuparinen and her colleagues are only the most recent to note, that shifting won't necessarily keep pace with a shifting climate. "In general," says Field, "we don't have very good understanding of the mechanisms that allow plants to move around on the landscape." Current estimates, he says, are based largely on studies of ancient ecologies. "But our models are mostly not validated for the modern, human-dominated environment...
Most of us can remember spending prefrosh weekend wandering around the Yard with bright red folders that our hosts weren't merciful enough to tell us to leave in our rooms. That special weekend in spring has always formally been called the "April Visiting Program"—but it looks like that might change soon...
