Slashdot videos: Now with more Slashdot!
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
This bit I found problematic:
While it is a fact that increased carbon dioxide in the atmosphere leads, all else equal, to higher atmospheric temperatures, the idea that we can predict the impact of global warming — and anti-global warming policies! — 100 years from now is sheer lunacy. But because it is done using math by people with tenure, we are told it is "science" even though by definition it is impossible to run an experiment on the year 2114.
Yet if science is about determining reliable predictive rules through experiment, then if we have experimentally shown the reliability and validity of those rules, we do not need to experiment on the year 2114 in order to make predictions. We just apply our reliable rules and they will give us predictions which are reliable to however much those rules are.
"If that is so, then why are we by far the most violent and aggressive species on earth?"
Are we? Remember: we will tend to notice our own violence more than that in some other species. We hear about it when there's another human war somewhere, but not when some pack of chimps decides to go after another. For this statement to be true, it would have to be that evolution favored the violent instinct far more in the human species than any other, and if so, why. Why would that be? There's only so much violent instinct a species can have before it would destroy itself.
And don't just go "But we've got the atomic bomb!" That is more a measure of how much _intelligence_ we have and can devote to violence than a meter gauging the amount of underlying violent instinct or impulse. One could argue that the combination of violence with intelligence reduces the threshold amount mentioned above as to when there is too much violent instinct for a species to destroy itself, since it makes acting on those impulses more destructive, even if the underlying impulse is not changed. I suppose then you could say humans may be "more violent" in terms of deaths caused, but this is due to intelligence, not necessarily a greater amount of underlying "violentness".
