A new study by researchers at Kansas State and North Carolina State Universities shows that warmer nighttime temperatures cause problems in rice and (potentially) wheat, altering their circadian rhythm behavior. This is a concern for farmers because temperatures overnight are warming twice as fast as daytime high temperatures. Warm overnights are linked to higher humidity values and, in cities, to more pavement. Other crops may also be negatively affected by the warm nights.
