- Observation Growing season temperatures in Iowa are projected to increase by more than 5°C by the end of the twenty-first century
- Observation Growing season precipitation in southeastern Australia is projected to decrease by 15% by the late twenty-first century
- Observation Temperatures in southeastern Australia are projected to increase by 2.8°–4.5°C by the late twenty-first century
- Observation Wheat yields in southeastern Australia are projected to decline by 70% by the late twenty-first century
- Association The frequency of low-yield years in southeastern Australia rises dramatically in the twenty-first century because of projected drying
- Association The frequency of high- and low-yield years in maize and wheat was related to changing local hydroclimatic conditions
- Association Historically high and low maize yields in Iowa tended to occur in anomalously wet and dry growing seasons, and this is exacerbated in the future
