Unequivocal Equivocation – an open letter to Dr. Trenberth

A must-read essay for everyone...

The “null hypothesis” in science is the condition that would result if what you are trying to establish is not true. For example, if your hypothesis is that air pressure affects plant growth rates, the null hypothesis is that air pressure has no effect on plant growth rates. Once you have both hypotheses, then you can see which hypothesis is supported by the evidence.

UPDATE: I just sent the above essay to the Climate Change wing of our university, and told them, in no uncertain terms, to get a reality check and stop wasting our tuition fees. I will post their reply when and if I get it.
