Keynesians are just like global warming researchers. The effects that they study are the result of innumerable interactions in complex and chaotic systems, which they analyze by building models which are necessarily incomplete and speculative. In order to get their models to fit the data, they tweak arbitrary parameters. They then use the predictive results from their model to support policy decisions which invariably require a paternalistic, benevolent, omniscient, and near-omnipotent government to intervene and “fix” things – for our own good.

You should write a post about econometrics sometime. I’m sure with your experience in business and business school you could rip it to shreds.

The way I see it, there’s really no doubt that global warming could potentially have disastrous consequences for humanity (_could_ not _will_). In a worst case scenario (which is probably not the most likely one) global warming caused by the sun could cause exactly the same problems that people claim global warming caused by humans will have. And it is also certainly true that greenhouse gases exist and that the more of them there are, the warmer our planet will be given a constant input of solar radiation. Giving an increasing input of solar radiation (which, it appears, we are currently getting), the prudent thing to do if we want to preserve the current climate patterns and avoid potentially losing out current crop lands (in my opinion the biggest problem that could potentially be caused by global warming) would seem to be to do whatever we can to reduce the concentrations of greenhouse gases in the atmosphere to allow more of the increased solar radiation our planet is/will be receiving to escape into space and not warm our planet.

It would be rather ironic if the global warming crowd was proved wrong about anthropogenic global warming, but the disasters they foretold still occurred. Just because it may not be our fault, doesn’t mean it won’t be our problem if it happens. Of course, if it’s the sun to blame and not us, their predictions for future warming are going to be completely off (unless they know that we aren’t the ones causing it and are just using the whole anthropogenic thing as a ruse to motivate people to do what they want, which I wouldn’t completely rule out).

And when I showed them that same website about the active sun, they dismissed it. An active sun just doesn’t fit their idea of evil people-made CO2 causing global warming.

And speaking of questions, no one has correctly identified water vapor as being the number one greenhouse gas.
