Marty Hoffert — an energy expert and climate modeler — posted this blunt comment on a recent DotEarth piece about a report on potentially large unconventional oil resources:
However welcome the news may be to market economists — and I’m confident Exxon-Mobil and company are licking their chops over continuing our highly profitable to them fossil fuel energy infrastructure — it’s an unmitigated environmental disaster for climate change: “Game Over,” as Jim Hansen rightly says.
Shale gas, shale oil and tar sands don’t fundamentally change estimates of total fossil fuel resources; but these “unconventional” sources, now more cost-effective to extract as fuel for the bottomless pit of world energy demand, will make disastrous climate shifts from the CO2 greenhouse a near-certainly.
