>I disagree. To actually know if greenhouse gases have an impact on Earth's average temperature, do we need a control Earth? In both cases the evidence is pretty clear.
We have much better evidence for global warming than "the temperature has been rising and CO2 is also present in the atmosphere". You say that "the evidence is pretty clear" but at least in your piece there's only your anecdotal experience with an unspecified number of people.
>On the other hand, doing a controlled experiment wouldn't be a bad thing, either, so if we just shut down the business schools for the next 50-100 years, perhaps we can find the answer at the end of the study and decide whether or not to open them back up again. :)
I know you're joking but that experiment has already been ran in reverse (from no MBAs to the present state), so that data should already exist. It's not much of an experiment though as you have a bunch of other relevant factors evolving at the same time.
