Climate change will make rice toxic, say researchers
- A new study reveals that climate change threatens rice, a staple food for over half the world.
- Rising carbon dioxide and temperatures may increase inorganic arsenic levels in rice, creating a toxicity risk.
- Researchers simulated growing conditions over years using Free-Air CO₂ Enrichment platforms across multiple rice varieties.
- The hazard quotient in Vietnam reached 12, far exceeding the safety threshold of 1, and China may face excess cancer cases.
- The study indicates an urgent need to lower arsenic exposure in rice through science, policy, and farming practice investments.

Half the world’s people depend on rice; new research says climate change will make it toxic
Rice, the world’s most consumed grain, will become increasingly toxic as the atmosphere heats and as carbon dioxide emissions rise, potentially putting billions of people at risk of cancers and other diseases, according to new research published Wednesday in The…
Climate change could make rice more toxic by boosting arsenic levels
Rice, a staple food for half the world’s population, may become increasingly toxic due to climate change, as new research finds that warming temperatures and rising carbon dioxide levels increase arsenic concentrations in the crop.Georgina Gustin reports for Inside Climate News.In short:A six-year study published in The Lancet Planetary Health shows that rising temperatures and carbon dioxide concentrations lead to higher levels of inorganic ars…
Climate Change Will Increase Arsenic Levels in Rice, Study Finds
Rice is the most consumed grain in the world, but new research has found that it will become more toxic as carbon emissions rise and the planet continues to heat up, potentially putting millions at risk of diseases. Climate change could have a major impact on the arsenic levels found in paddy rice, according to a new study by researchers at Columbia University’s Mailman School of Public Health and colleagues at the Chinese Academy of Sciences an…
