By combining regional temperature projections with detailed maps of the underlying topography, then adding in the physics of ice flow, the authors project not only that the glaciers of Western Canada will lose at least 70 percent of their volume by 2100 — a number more or less in keeping with current projections — but show exactly how every individual glacier will shrink.

It's important to understand why models can produce such good agreement in light of the large uncertainties in radiative forcing and climate sensitivity, and how all the models which produce similar 20th century trends can disagree by a factor of two or three in 21st century temperature projections.

The passage in question comes from Carlin's section 1.3, entitled IPCC Global Temperature Projections Look Increasingly Doubtful.

Despite recent less - intense warming and the fact that past temperature projections were not intended to predict warming over short time spans, the IPCC reported that «the observations through 2012 generally fall within the projections made in all past assessments.»

To make mortality estimates, the researchers took temperature projections from 16 global climate models, downscaled these to Manhattan, and put them against two different backdrops: one assuming rapid global population growth and few efforts to limit emissions; the other, assuming slower growth, and technological changes that would decrease emissions by 2040.
