Until there's a controlled, replicable method, all these studies, approaches, genius ideas are just blah-blah-blah exercises in pretty correlations.
I'm also not sure what you mean by "controlled". For example, in the china study the group that ate more meat was compared to a similar group in the same country with the same lifestyle. Isn't this the definition of a control group?
Obviously not. You just offered the definition of uncontrolled.
> climate change is just blah
Well he makes a pretty good point that data dredging for correlations is bad science. But the real reason climate change is "blah" is that the world isn't actually warming. Clearly shown for over ten years now by satellite and ground station data. There was only warming after a long cooling trend that lasted into the 70s.
