Burning all known quantities of tar sands oil would raise earth's temperature by 4 degrees Celsius: #350ppm #noKXL

Burning all known quantities of tar sands oil would raise earth's temperature by 4 degrees Celsius: #350ppm #noKXL

A study published this morning has been widely heralded as a clean bill of health for tarsands oil, because it shows—unsurprisingly—that burning the planet’s huge coal reserves would do even more damage. But even a quick read of the data demonstrates that there’s more than enough carbon in the planet’s various tarsands formations to cause huge damage. If we burn through the know quantities of tarsands oil, that alone will raise the planet’s temperature by .4 degree Celsius —which is about exactly how much we’ve already raised the planet’s temperature by burning everything we’ve burned since the start of the Industrial Revolution. That is to say, the tarsands alone would provide half again as much warming as we’ve already experience—a warming severe enough so far that summer sea ice in the Arctic has declined by 40% and the atmosphere has grown steadily wetter leading to vi...
