Other claims from this paper (6)
- Association Climate changes from 1961 to 2010 significantly reduced simulated national rice yield by 11.5% in China.
- Association Changes in growing-season radiation and diurnal temperature range, rather than growing-season temperatures, contributed most to the simulated rice yield reduction.
- Association A 1°C growing-season warming decreased rice yield by roughly 4% in rice areas with mean growing-season temperature at 12–14°C or above 20°C.
- Mechanism The warming-related yield decrease is partly attributed to increased heat stress and shorter growth period.
- Association In southern China and the Yangtze River Basin rice areas with growing-season temperature above 20°C, decreased growing-season radiation partly explained the simulated yield decline.
- Association Recent global dimming made a significant negative contribution to rice production in China's main rice areas.
