In this video I will explain what is the diurnal temperature range. It is the range of the lowest temperature in a 24-hour period to the highest temperature in the same 24 hours. I will also explain why the smaller the range, the more effective the greenhouse gases; and the larger the range the less effective the greenhouse gases.
