Friedman is quite absurd. He begins his column by mocking people who are saying "because Washington is having a particularly snowy winter it proves that climate change is a hoax and, therefore, we need not bother with all this girly-man stuff like renewable energy, solar panels and carbon taxes."
But then he turns around and says "The fact that it has snowed like crazy in Washington — while it has rained at the Winter Olympics in Canada, while Australia is having a record 13-year drought — is right in line with what every major study on climate change predicts: The weather will get weird; some areas will get more precipitation than ever; others will become drier than ever."
So weather is not climate — which, duh — but he still wants to use weather as climate. And he even gets to say that cold is evidence of heat, because we shouldn't be saying heat anymore, we should be talking about weirdness.
Come on, that's really weird.
I see the analogy between global warming and the weapons of mass destruction used to justify the Iraq war. Those who planned the war believed there were other good reasons to go to war with Iraq, but they made a decision to use weapons of mass destruction as the reason to go to war, because they thought people could understand this reason and unite behind the war effort. But then, when the WMD were not found, the war looked like a big mistake.
Now, think about the analogy. Think about how people support the policies that are supposed to deal with global warming — renewable energy, solar panels, carbon taxes, etc. — and what other reasons they have for wanting those policies. Think about why they would decide to rely on the global warming prediction rather than those other reasons, and how they will need to scramble if the global warming theory proves untrue or is no longer believed.
If global warming were the only reason for doing the things that are needed to deal with global warming, then no scrambling is required. We can simply be happy about it. But the scrambling... that's what shows that people wanted the policies anyway. And maybe they are right! Maybe going to war in Iraq was right even without WMD.
So why not stress the other arguments for renewable energy, solar panels, carbon taxes, etc.? Because it's not scary enough! Running low on traditional fossil fuel — the old energy crisis — just isn't crazy-making enough to get the public to accept great sacrifice and pain.
