Good Science tends to be rather aware of its limitations.
Bad Science Journalism tends towards dogmatic assertions of absolutism just as much as many religious folk.
"Error bars", "p-values", "uncertainty values/ranges" are the norm in Science, not the exception.
Here you're juxtaposing two separate issues. First "the science is settled" appears to be a remark or jab at the idea that the overwhelming consensus among relevant Scientists and relevant peer-reviewed studies is that global average temps are increasing and that human activity has played a measurable, significant part of that. Second, the projections for how much temp increase by 2100 and 2200 are not exact at all. They're given as a range with a corresponding uncertainty. Supposedly, this latest study/model serves to narrow that range. It's just like the difference between someone telling you it will snow tomorrow and you'll get between 1 and 47 inches vs. another person saying between 4 to 5 inches. Both predictions are somewhat uncertain but one is less so.
