Make sense. Global climate is too complicated for scientists, who arrogantly think too much of themselves, to be able predict with certainty that the climate is indeed warming and then make then make the leap that it is caused by humans.
Good science would know that the variables implicated in global climate are too multifarious and too hidden from observation (and too chaotic) to be able to predict the results, although trends to date do not appear to be alarming. Chicken Little should be sent back to his farm. All he can see is one thing.
