How Do Hard Data and Computer Climate Models’ Dire Predictions Compare?

Nobel Prize-winning physicist Richard Feynman explained “the key to science” this way: In general we look for a new law by the following process. First we guess it. Then we compute the consequences of the guess to see what would be implied if this law that we guessed is right. Then we compare the result
