The global climate never stops changing. Everything changes, even the global climate. Is it getting warmer? Or colder? That’s for the scientists to answer, and it appears that they will take a very long time to come to anything remotely approaching a consensus, which means that all the polarized rhetoric, Gore-bashing, etc. is just so much hot air (not enough to warm the globe, fortunately, though sometimes I wonder).
Is humanity affecting the climate? We’ve affected many other things as our numbers have increased by a factor of 6 in less than two centuries – a blink of an eye in natural time. If our numbers keep increasing as they have, and our energy use keeps increasing as it is, we will affect the global climate at some point, if we aren’t already. That is another point for scientists to study, and about which there will also probably never be complete agreement. Generally, though, if we are affecting the climate, it is as much tied to our energy use as anything. (more…)
