A warmer world will have much more dangerous cloud-to-ground lightning capable of igniting more forest fires, according to a study published Thursday in the Journal Science. The research found that for each degree Centigrade (1.8°F) of global warming, lightning in the U.S. is expected to increase by 12%. This would result in about a 50% increase in lightning by the year 2100, assuming business-as-usual emissions result in a world that is 4°C (7°F) warmer. Main au...
