Agricultural data gathered over a dozen years at a rice paddy in the Philippines suggest that climate changes brought about by global warming could significantly diminish rice yields.

On some plots, researchers have grown the same variety of rice with the same agricultural techniques since 1992, says Kenneth G. Cassman, an agronomist at the University of Nebraska in Lincoln.
