I wonder why they keep saying that global warming will mean less rain. What do they think will happen to all the water as it evaporates? Will we just have clouds all the time and no water falling back to earth. Will the whole earth dry up while the cloud layer gets so heavy that it scrapes the ground over the whole of the earth? Scientists are like liberals, they think the average person is extremely stupid. Millions of years ago the earth had no polar caps and the weather was moist over a large part of the earth. Can't get much warmen then that. What jerks.
