Question

Quizplus · Accepted Answer

Jet contrails can decrease the daily temperature range by reflecting sunlight during the day and creating a greenhouse effect at night, trapping heat near the surface. This effect can lead to both warmer minimum temperatures at night and cooler maximum temperatures during the day, thus reducing the daily temperature range.
