The study, which used downscaled climate model simulation projections for Nepal, anticipates temperature increases of 3-5C by the end of the century.
Led by the geochemist Andrea Dutton and published in the journal Science, the second paper uses deep history, not model projections, for clues to the future.
When I asked Richard Seager, who analyzed historical records and climate model projections for the Southwest for the Lamont-Doherty Earth Observatory at Columbia University, if a perpetual drought was possible there, he replied: "You can't really call it a drought because that implies a temporary change.
Future precipitation trends, based on climate model projections for the coming fifth assessment from the Intergovernmental Panel on Climate Change, indicate that droughts of this length and severity will be commonplace through the end of the century unless human-induced carbon emissions are significantly reduced.
Model projections for western Iberia suggest that a large area is environmentally suitable in both Portugal and Spain.
However, the characteristics of model projections for marine species from these different approaches have rarely been compared.
For example, the cod population could become extinct [8] under some of the more severe salinity reductions (ca. 50%; [28]) seen in some climate-ocean model projections for the Baltic.
Furthermore, within the model projections for the first quarter of the 21st century, there were differences between the four scenarios.
For the GYE pilot, we relied on the opinion of experts on climate model projections for the region to outline plausible scenarios.
We have analyzed long-term meteorological datasets along with regional climate model projections for the 21st century, based on the intermediate IPCC SRES scenario A1B.
