science or opinion?
I don't comment as a rule but I am worried that Lewis is painting himself further into his corner with these articles. I aknowledge the need for scientifc debate, history is full of facts that were disproven through vigorus scienctific methods but Lewis's pieces always read as if they are more personal opinion or religious zelotry. It is amazing to think that you can read historical weather patterns from tree rings but I expect you just need very old trees that lived through those periods and lots of them.
