Read Thomas Friedman's piece, "The Power of Green" in this past Sunday's Times Magazine. I have long loved Friedman's work (which I can no longer read because the Times obnoxiously hides their Op-Eds behind their subscription service). He has always tackled the issues I think are most critical to understanding and changing the world and he does it without the burden of a political agenda.
In this particular case he makes the argument that climate change is the most important issue of all, and we'd better start facing up to it. But he does it in the way he always does, with a can-do optimism that suggests the ways we can face the challenge instead of merely bemoaning its existence. Friedman has always embodied some of my favourite things about America: harsh realist, willing to sacrifice to live up to a challenge and fiercely competitive. He talked this way about the war in Iraq for a long time (and I agreed with nearly everything he said) before it descended into its present state of depressing inevitability.
There are lots of excellent points in the article that I'd like to highlight, but I'm too tired. So instead, just read it.
