Plant growth declines as warming causes drought

WASHINGTON – Plant growth that had been spurred by global warming has reversed, despite temperatures that continue to rise.

Researchers say the change could affect food security and development of biofuels.

The amount of carbon taken up by growing plants increased from 1982 through 1999 as temperatures rose and the amount of carbon dioxide in the atmosphere increased.
