Global Warming Was Already Influencing Droughts in Early 1900s, Study Shows

Global warming has been fueling droughts since the early 20th Century, when soils started drying out at the same time across parts of North and Central America, Eurasia, Australia and the Mediterranean, new research shows. The researchers say the surprising early-century findings provide the clearest signal yet that human-caused greenhouse gas emissions are changing the hydroclimate in ways that can devastate agriculture, health and livelihoods.
