But climate change is still in the air, and the recent weather pattern is a harbinger of what’s to come. The abrupt shift to record rainfall is the kind of extreme weather forecast for a warming planet. “Current models suggest the dice are loaded toward an increased probability of this kind of year,” said Columbia University climate scientist A. Park Williams.
