Global warming is accelerating 5,000 times faster than rice can evolve
A recent study indicates that global warming is accelerating at a rate 5,000 times faster than rice can evolve. This rapid change threatens rice cultivation, which is vital for over a billion people worldwide. Researchers warn that many regions currently suitable for rice may soon become too warm for the crop to thrive.
- ▪Climate change is pushing rice-growing regions into temperatures beyond those at which rice has been cultivated for the past 9,000 years.
- ▪The study suggests that warming is proceeding 5,000 times faster than rice has ever evolved.
- ▪Rice is a staple crop for over half of the world's population, with 90% of cultivation occurring in Asia.
