And then on climate change, our opinion—and it’s my opinion, this is a very personal thing—is that there is sufficient evidence of an increase in the level of emissions in the atmosphere to be concerned about the effect that it may have on the climate. But the science of climatology is by no means complete, and it is going to take a long time before we really know what the effect of these emissions is going to be. In the meantime, it is prudent and reasonable to try to reduce those emissions as much as we can.
Remember, that's not a hemp-wearing hippie talking. It’s not Al Gore, or Joe Romm, or any number of climate activists. It’s Andrew Gould, CEO of a $23 billion a year oil services company—a company with a vested interest in climate change not being real. If even he can admit that climate change is probably real, and that it makes sense to invest a small percentage of our wealth in averting its worst effects, surely even the most skeptical libertarian can admit that climate change may not be a hoax after all.
