I used the phrase "Great Carbon Transition" in my last post, and then wondered where I had gotten it. I did a phrase search and found...that it had come from the inside of my own head. Google found no other uses.
I think this is a great term for what the next fifty years or so are going to involve. And it's the kind of absurd Capitalized Phrase For A Historical Period that always appears in SF novels set in the far future to describe historical events that occured between that time and the present, which real people so seldom use.
But we are, after all, the future's past, so Great Carbon Transition it is. Remember, you heard it here first.
