TL;DR: In this paper, the performance of a set of 15 global climate models used in the Coupled Model Intercomparison Project is evaluated for Alaska and Greenland, and compared with the performance over broader pan-Arctic and Northern Hemisphere extratropical domains.

TL;DR: In this paper, the Anaktuvuk River Fire coincides with extreme sea ice retreat, and tundra area burned in Alaska is moderately correlated with sea ice extent from 1979 to 2009 (r = −0.43, p = 0.02).

TL;DR: In this paper, the authors used daily output from seven GCMs run under late-twentieth century and projected twenty-first century radiative conditions (SRES A1B greenhouse gas emission scenario) to analyze the behavior of extreme cold-air outbreaks under recent and future climatic conditions.

TL;DR: In this article, the authors evaluated the relationship between cloudiness, radiative fluxes, and surface air temperature in the central Arctic from measurements made at Russian drifting ice stations, and atmospheric reanalyses of the National Centers for Environmental Prediction (NCEP) and the European Centre for Medium-Range Weather Forecasts (ECMWF).

TL;DR: In this paper, a variety of historical sources have been synthesized into a database extending back to 1850 with monthly time-resolution, and the synthesis procedure includes interpolation to interpolation.
