PricewaterhouseCoopers Climate Change Warning

It may already be too late to keep global temperatures within the scientifically agreed upon upper threshold of 2 degrees. This is the conclusion of a report from the global business consultancy PricewaterhouseCoopers (PwC). Their report entitled "Too Late for Two Degrees?" suggests that even with a modest effort, global temperatures will continue to increase.

"Even doubling our current rate of decarbonization, would still lead to emissions consistent with 6 degrees of warming by the end of the century," noted Leo Johnson, a partner in PwC's Sustainability and Climate Change unit, in the report. "To give ourselves a more than 50 percent chance of avoiding 2 degrees will require a six-fold improvement in our rate of decarbonization."
