The IPCC range, on the other hand, encompasses the overall uncertainty across a very large number of studies, using different methods all with their own potential biases and problems (e.g., resulting from biases in proxy data used as constraints on past temperature changes, etc.) There is a number of single studies on climate sensitivity that have statistical uncertainties as small as Cox et al., yet different best estimates — some higher than the classic 3 °C, some lower.

That may mean that some of the highest estimates of future temperature rises, of more than 6C within several decades, are less likely, but it does not let the world off the hook — warming of more than 2C is still highly likely on current high emissions trends, and that would cause severe consequences around the world.
