Climate change scenarios in New York State, what about the weeds?

From the 2011 report on the potential long-term effects of climate change in New York State (pdf here, very interesting read):

"Carbon dioxide fertilization tends to preferentially increase the growth rate of fast-growing species, which are often weeds and other invasives."

"Increased weed and pest pressure associated with longer growing seasons and warmer winters will be an increasingly important challenge."
