Minimum temperatures are rising faster than maximum temperatures

A new study published recently by the Royal Meteorological Society has confirmed what climatologists have known for quite a while–minimum temperatures (which are usually observed around sunrise) are rising faster over time than maximum (daytime) temperatures. One of the results of this is that the daily temperature range between max and min temperatures is decreasing. Warmer nighttime temperatures are most worrisome for heat stress in livestock in summer but they also can affect the growth of some crops like corn.
