The unscientific method

As I’ve written before, the main problem with global warming alarmism isn’t the reconstructions of the Earth’s past climate (which I haven’t the scientific expertise to debate), but the predictions for the future. The basis of the scientific method is to generate testable hypotheses, and then test them. The models that climate scientists use to predict long-term changes to climate simply cannot be tested over the short-term. In regards to long-term changes, they are simply unscientific.

Worse, when those same models are used to make short-term predictions, which can be tested, they tend not to come true. Two cases in point:

First, a new report from the British Met Office and the (infamous) Hadley CRU shows that the Earth has not warmed since 1997. Now, any particular year is mostly noise, but this is 15 years without any trend:

Second, a new study from the University of Alabama shows that snowfall in the Sierra Nevada hasn’t changed for 130 years:

The analysis of snowfall data in the Sierra going back to 1878 found no more or less snow overall – a result that, on the surface, appears to contradict aspects of recent climate change models.

The science of global warming, at as regards the future, isn’t settled. Strictly speaking, it hasn’t even begun.
