Except that the IPCC has always overestimated the warming.

This is completely useless as the end result of an experiment, and you know it. So far, the IPCC predictions have all overestimated the temperature increase, unlike the standard acceleration due to gravity, which has been calculated quite precisely. So the much vaunted climate models do not match reality yet. This is not the first, nor will be the last time large segments of the establishment have been wrong.

So, if it's an experiment, what's the Null Result?

It's easy to do experiments that test gravity. Much, much harder to test climate change.

That's actually a very reasonable question. A hundred years ago, Heroin was not banned. There was no epidemic of junkies either.

There's one theory that suggests PUFAs are unnecessary. Avoid Omega-6 and you don't need the Omega-3 either.

People say that all the time, but there are plenty of useful effective supplements. Many of the vitamins, for example.

I consider myself in the middle-aged category, heh.

You are exactly wrong. It is young people who are willing to work for less pay. Old people on the other hand have a better idea of how much their expertise is worth. Lets face it, slashdot is getting middle-aged.

"You don't want more than $38,500." Oh, wait, sorry. :P
