I don't understand what you mean. Are you saying that the thing that's measurably happening now, right outside your window, that we as climate scientists told you was going to happen 20, 30, 40 years ago, is a wild assertion? The thing that every peer reviewed climate scientist in the world is screaming for action over, is a wild assertion? That has been borne out in climate modelling undertaken on literally billions of iterations of some of the most complex and advanced computer models invented by humans is a wild assertion?
Or do you think that we just sit in an office and play minecraft all day and spunk out a report at 4pm on a Friday?
