The arctic has been warming faster than the models have predicted. Due to the too many unknowns of feedback loops from melting permafrost, clathrates, and albedo, they are often simply left out of the models to make estimates more conservative. Also, there could be C02 growth from fossil fuels in a stagnant economy, as economies move to cheaper fuels. Natural gas prices won't stay cheap, oil is expensive, and we're already seeing a rise in coal use. Also, extraction of natural gas by fracking and oil sands, etc., is more carbon intensive. Sure you can dismiss their rosy projections on emissions and economic growth, but there's other issues with the modelling and projections as well.
