- Observation Projected sugarcane dry-matter yield increases under RCP8.5 were 2.9, 5.4 and 8.5 t ha−1 for the 2030s, 2060s and 2090s against baseline.
- Observation Projected sugarcane sucrose yield increases under RCP4.5 were 5.2, 7.0 and 8.3 t ha−1 across the future periods.

- Association Sugarcane yield had no significant relationship with solar radiation changes.
- Association Sugarcane yield was significantly correlated with rainfall changes.
- Association Sugarcane yield was significantly correlated with temperature changes.
- Association Combined radiation, rainfall, temperature and elevated CO2 changes may explain 76% of sugarcane sucrose yield changes.
- Association Increased temperature caused a small increase in sugarcane yield.
- Association Increased rainfall significantly increased sugarcane yield until a limit was exceeded.
- Association Sugarcane yield decreased when rainfall exceeded a certain limit.
- Association Sucrose yield increased with temperature at constant radiation.
- Association Sucrose yield decreased when radiation exceeded a certain limit.
- Association Temperature changes increased sucrose yield only when radiation and temperature increased together.
- Association Rainfall increased sucrose yield, though the amplitude was limited.
