Andy,
They will change their minds soon enough. Even now you see Fox and the GOP starting to soften their stances. Previously it was a liberal conspiracy, now it's "I'm not a scientist." Pretty soon it will be recognized, and the propaganda will change, easing the doubters into it, and people like the ones you're talking to in this thread will forget they ever denied that climate change was real. Why the delay on the right wing? I don't know. Maybe the existing power companies wanted time to develop green tech? Wish I knew.
