As reported by environmentalist Bill McKibben, writing in the New Republic, the latest calculations show that if we burn the fossil fuels in the mines and wells that already exist, Earth's surface temperature rise will exceed that 2 degree limit.

According to these new calculations, adding 800 gigatons (800 billion tons) of CO2 into the atmosphere will push the climate through the 2 degree C. limit. There are 942 gigatons waiting to be extracted from existing mines and wells to be burned. Do the math.
The sobering conclusion is that we can't afford to drill any new oil wells, dig any new coal mines, or open up any more territory for fracking. If we're serious about controlling global warming, McKibben writes, "we're done expanding the fossil fuel frontier."
The problem is that fossil fuel companies have no intention of abandoning the reserves and leases that are crucial to their future profits--their potential "stranded assets." According to Carbon Tracker, that could amount to some $2 trillion. Two trillion dollars represents a lot of motivation to keep drilling and digging no matter what the environmental and societal costs, and makes investing a few hundred million to influence elections, lawmakers and regulators seem like a pittance.
Still, if we're in the biggest hole ever, as McKibben says, the simple answer is, "stop digging."
