I take your point. I just don't know if that's included in the "sustainability" of an energy source. I'm sure you're right--it isn't what the term "sustainability" usually means when it comes to an energy source. For now. My guess and prediction is that in 10 years, probably sooner if we get effective leadership on the issue, it is what out u nderstanding of the term will come to include vis a vis energy. As we continue to get more extreme weather (records on this are being set with greater frequency over the past few years), as a few small island "nations" get increasingly swamped and even disappear altogether (the first ones are distressed already), as salt water begins to encroach on coastal aquifers, as more ice shelves calve and glaciers disappear, as more flooding occurs due to snow melt happening more and more quickly and earlier in the season (cf Maine in the last couple of days)--all these things are consistent with the IPCC perspective, although most of them are happening more quickly than predicted--and as the circumstantial evidence continues to build, the number of deniers will continue to dwindle, and it will not only be a scientific consensus that fossil fuel emisisons are a leading cause of climate change, but a political consensus as well (a consensus that already exists in most of the scientifically educated world now). The next few decades will see even more (and more rapid) change than even the last two, which have seen plenty, especially since the advent of internet and China and India getting serious about their economies. How we will survive all that change, I don't know.
