Plants may run out of time to grow under ongoing climate change

A key potential ‘benefit’ of global warming–namely, that plants at northern latitudes will thrive in a warmer world–is challenged by a new study released by University of Hawai’i scientists today. The prevailing assumption ignores the fact that plants in the North will remain limited by solar radiation, curbing positive effects of warming and additional CO2 availability. In addition, that same warming …
