Global Warming, in Context
Ξ March 2nd, 2010 | → 0 Comments | ∇ Intellectual, Politics |
A post over at Watts Up With That a few months ago caused quite a stir in the global warming debate. I meant to post about it then, but forgot until now.
Of particular note over the last few years was the “Hockey Stick Graph”, which showed a rapid rise in temperatures, and is featured frequently in discussions on Global Warming. The graph has come into some controversy, as a growing number of people question it’s accuracy. But the unique thing about the Watts Up With That post is that it puts aside those arguments and says, “Let’s assume it’s correct for a minute. Let’s look at it in the context of historical ice-core samples from Greenland and the Antarctic”. The result, to my mind, is pretty damning of the hysteria surrounding Global Warming.
In it, it shows that, if one frames the graph over the last 600 years or so, you end up with a picture very similar to the Hockey Stick graph. But, as one stretches out the view to include more time, the change in temperature becomes smaller and smaller, eventually becoming irrelevant when compared to the much larger variations that have occurred over the last half-million years.
I wanted to get some sort of confirmation of what I was seeing, and sure enough, I checked out the Wikipedia article on Ice Cores, and there was a plotting of Vostok Ice Core data the mirrored what was compiled by Watts Up With That.
In fact, one gets the impression that the whole of modern human civilization has occurred during a relatively brief warm period, and that the temperature variations we’ve seen over the last hundred or so years are insignificant compared to what happens naturally. Perhaps we should stop worrying about how to deal with things beyond our control and focus on things that we can. Clean, renewable sources of energy are worth-while in their own right, not because the world is going to end in the next ten years.
