Can this be a correct reporting of the IPCC’s forthcoming report?

THE world’s top climate scientists have cut their worst-case forecast for global warming over the next 100 years.

A draft report by the Intergovernmental Panel on Climate Change, obtained exclusively by The Weekend Australian, offers a more certain projection of climate change than the body’s forecasts five years ago.

For the first time, scientists are confident enough to project a 3C rise on the average global daily temperature by the end of this century if no action is taken to cut greenhouse gas emissions.

The Draft Fourth Assessment Report says the temperature increase could be contained to 2C by 2100 if greenhouse gas emissions are held at current levels.

Is the climate policy debate really about the difference between a global average temperature change of 2+ and 3 degrees C over the next 93 years?
