I listened to a man today talk about how global warming model are way off in determining the warming predictions of the earth. They have learned that the sun has a more profound effect on the climate than before as the sun cycles and is not a constant source and is enough to throw off all the modeling. Apparently they have satellites now capable of measuring more accurately how heat escape the atmosphere and that too is happening at a much faster rate than the modeling inferred.
That the models are way off is nothing new. To put it in a more course term, the figures are pulled out of someone's backside that go into the computer modeling. The only thing I have issue with in those "OMG WE ARE OVERHEATING THE EARTH" arguements is whether humans are causing it or not. Yes, the weather is odd the last few years and does match the "global warming" theory or whatever you want to call that hypothesis today.
But really those computer models they go for are garbage. They cannot predict the weather accurately 48 hours in advance, how am I to believe they are doing it years in advance? I don't. Only historic data is reliable.
