TLDR
In this paper, the authors proposed a scaling procedure to provide finer spatial detail of the model results. But, because of the planetary scope of the GCMs, their resolution, or level of detail, is somewhat coarse.Abstract:
Global climate models (GCMs) are the fundamental drivers of regional climate-change projections (IPCC 2007). GCMs allow us to characterize changes in atmospheric circulation associated with human causes at global and continental scales. However, because of the planetary scope of the GCMs, their resolution, or level of detail, is somewhat coarse. A typical GCM grid spacing is about 62 miles (100 km) or greater, which is inadequate for creating projections and evaluating impacts of climate change at a regional scale. Thus, a “downscaling” procedure is needed to provide finer spatial detail of the model results.read more

Expansion of the Hadley cell under global warming: winter versus summer
Jian Lu,Sarah M. Kang +1 more
TL;DR: In this article, a scaling relationship is introduced to explain the seasonality in the outer boundary of the Hadley cell in both climatology and trend in the simulations of phase 3 of the Coupled Model Intercomparison Project (CMIP3).

Towards process-informed bias correction of climate change simulations
Douglas Maraun,Theodore G. Shepherd,Martin Widmann,Giuseppe Zappa,Daniel Walton,José M. Gutiérrez,Stefan Hagemann,Ingo Richter,Pedro M. M. Soares,Alex Hall,Linda O. Mearns +10 more
TL;DR: In this article, the authors consider the issues of bias correction and make recommendations for research to overcome model biases, and conclude that bias correction cannot overcome major model errors, and naive application might result in ill-informed adaptation decisions.

TL;DR: In this article, the authors identify four major sources of disparities among studies that arise from both methodological and model differences, including differences in 1) the global climate models (GCMs) and emission scenarios used; 2) the ability of land surface and atmospheric models to simulate properly the high-elevation runoff source areas; 3) the sensitivities of land-surface hydrology models to precipitation and temperature changes; and 4) the sensitivity of hydrological models to land surface hydrology model to high elevation.

Urban forestry and cool roofs: Assessment of heat mitigation strategies in Phoenix residential neighborhoods
TL;DR: In this article, the authors investigated the impact of the City's heat mitigation strategies on daytime microclimate for a pre-monsoon summer day under current climate conditions and two climate change scenarios.

Western water and climate change.
TL;DR: Four iconic river basins offer glimpses into specific challenges that climate change may bring to the West, including the Colorado River, which is a system in which overuse and growing demands are projected to be even more challenging than climate-change-induced flow reductions.

Climate change 2007: the physical science basis
Susan Solomon,Dahe Qin,Martin R. Manning,Melinda Marquis,Kristen Averyt,Melinda M.B. Tignor,H. L. Miller,Z. Chen +7 more
TL;DR: The first volume of the IPCC's Fourth Assessment Report as mentioned in this paper was published in 2007 and covers several topics including the extensive range of observations now available for the atmosphere and surface, changes in sea level, assesses the paleoclimatic perspective, climate change causes both natural and anthropogenic, and climate models for projections of global climate.
