Rice yield declines in Asia

Rice yields declining under global warming

"Global warming is cutting rice yields in many parts of Asia, according to research, with more declines to come."

Yields have decreased 10-20% in the last 25 years in some areas.

The theorized mechanism that causes the decline: when it's hotter at night, plants need to respire (breathe) more, so they expend more of their energy at a time when they are not able to photosynthesize.
