Scientists expect the rising humidity to cause heavier rains, stronger hurricanes, and increased human heat stress.More info at National Geographic.
Climate scientists have long predicted that a warmer world will allow more water to evaporate, thus making the planet more humid.
Indeed, several studies have shown trends of increasing surface humidity around the planet, but until now scientists were uncertain what was driving the trend.
The new study combined a fresh data set of surface humidity with climate models, "and actually attribute[s] those trends to human influence," said study co-author Nathan Gillett, a climate scientist at the University of East Anglia in Norwich, England.
