Recently, Kevin Trenberth, Jim Hansen and a number of other leading climate scientists have stopped saying the standard line, "Extreme weather has many causes, and there's no way to tell whether warming caused this event," and begun emphasizing instead that warming almost certainly contributed to the event.
