The Other Global Warming: Why Coal and Nuclear are Wrong for Our Future

Please read article, cited after the quote. Articles open in a new window.

Human civilization will heat up the planet; the glaciers will melt and the seas will rise. It’s a familiar refrain by now, with a familiar solution: stop pumping out the greenhouse gases that trap the sun’s heat.

But even if we bring the greenhouse effect under control, says a Tufts astrophysicist, the earth will warm up anyway, thanks to a completely different source of heat that we create ourselves.

Over the next 250 years, calculates Eric J. Chaisson in a recent paper, the earth’s population will start generating so much of its own heat – chiefly wasted from energy use – that it will warm the earth even without a rise in greenhouse gases. The only way to avoid it, he says, is to rethink how we generate energy.
