Another curious aspect of the data, not mentioned in The Great Global Warming Swindle,is that as well as there being a lag on the way up there is also a lag on the way down. The significance being that global temperature can fall even while CO2 levels are still rising, which is kind of a kick in the teeth for the CO2 = Global Warming fanboys Now,whilst this data does not definitely disprove that CO2 plays some part in global warming it certainly doesn’t constitute proof that it does either.
Famous for 15 megapixels Of course nobody claimed it did, not even Al Gore methinks. This is certainly unintuitive but then multi-variable feedbacks normally are. Actually it’s really not that hard to come up with a reason why an effect should decrease even when a cause is increasing. Example: pressing down on the accelerator of a car normally makes the car go faster. Now try the same thing while aiming the car at a wall, or when it is nearly out of fuel.
