The article reports that a couple of meteorologists have claimed in a controversial new theory that questions man's fundamental understanding of what drives the weather. They believe vast forests generate winds that help pump water around the planet. If correct, the theory would explain how the deep interiors of forested continents get as much rain as the coast. It suggests that much of North America could become desert, even without global warming.
