Wow. Only enough reserves to be measured in decades? Once it's gone it's gone. Genuine Carboniferous coal, one day a thousand years from now, might be a rare museum item!

I have a habit of thinking about history in very long terms, and that just does not sit right with me. That kind of thinking (oh we have enough for decades, let it rip!) happens, and the decades pass, and time inevitably is less kind to the descendants of such decision makers.
