Baseline (1961-1990) average winter temperature in and projected change in temperature for for the northern portion of Alaska. For the purposes of these maps, ‘winter’ is defined as December - February. The Alaska portion of the Arctic LCC’s terrestrial boundary is depicted by the black line. Baseline results for 1961-1990 are derived from Climate Research Unit (CRU) TS3.1 data and downscaled to 2km grids; results for the other time periods (2010-2039, 2040-2069, 2070-2099) are based on the SNAP 5-GCM composite using the AR5-RCP 8.5, downscaled to 2km grids.

For the purposes of these maps, ‘winter’ is defined as December - February. The Alaska portion of the Arctic LCC’s terrestrial boundary is depicted by the black line. Baseline results for 1961-1990 are derived from Climate Research Unit (CRU) TS 3.1.01 data and downscaled to 2km grids; results for the other time periods (2010-2039, 2040-2069, 2070-2099) are based on the SNAP 5-GCM composite using the AR5-RCP 8.5, downscaled to 2km grids.

Hydrologic processes greatly influence Alaska’s physical and biological resources and the human communities that depend upon them. These processes will also be greatly impacted by expected changes in climate, including warming temperatures and changing seasonal precipitation patterns and amounts. However, current understanding of those impacts is limited. Improving that understanding is a first step toward assessing how the likely changes in hydrology will impact other physical and biological processes. The Western Alaska LCC and the Alaska Climate Science Center, with support from other LCCs, hosted a workshop of 28 hydrologists, researchers, fisheries biologists, local experts and managers for a workshop structured...

Alaska’s freshwater resources, vitally important for salmon and other species, are vulnerable to changes resulting from climate change. Though temperature is a critical element in the suitability of aquatic habitats, Alaska’s stream and lake temperature monitoring is occurring through independent agencies/partners without a means to link and share data. Because a coordinated network of monitoring data can help scientists and managers understand how aquatic systems are responding to climate change, conducting an inventory of past and present stream and lake temperature monitoring efforts has been identified as a priority science need for Alaska. This project consolidated existing monitoring site locations and attributes...

The maps show baseline (1961-1990) average air temperature and projected air temperature for the decades spanning 2010-2039, 2040-2069, and 2070-2099. Temperature is expressed in both Celsius (у) and Fahrenheit (ц). Baseline results for 1961-1990 are derived from Climate Research Unit (CRU) TS 3.1. data and maps for future time periods are based on a composite of projections from five GCMs (CCSM4, GFDL-CM3, GISS-E2-R, IPSL-CM5A-LR, and MRI-CGCM3) under the AR5-RCP 6.0.

Baseline (1961-1990) average air temperature (degree F) for Alaska and Western Canada. This zip file contains three GeoTIFF rasters. The file names identifies whether a file represents an annual mean or a seasonal mean (i.e., summer or winter). Summer is defined as June - August; winter is defined as December - February. Baseline data are derived from Climate Research Unit (CRU) TS 3.1 data. CRU data courtesy of Scenarios Network for Alaska and Arctic Planning.

This is a collection of GIF-format animations and PNG images that are suitable for presentations. These products include images for the baseline period (1961-1990) and images for each decade between 2010 and 2090. Baseline values are derived from Climate Research Unit (CRU) TS 3.1. or TS 3.1.01 data; values for future time periods are based on the SNAP 5-GCM composite under the AR5-RCP 6.0 and AR5-RCP 8.5. CRU and GCM data are provided courtesy of Scenarios Network for Alaska and Arctic Planning (SNAP).Air temperature is expressed in units of Celsius (у) and Fahrenheit (ц) and precipitation is available in units of millimeters (mm) and inches (in). Special note about animations: The first image of the animation...

Arctic wetlands, where millions of local and migratory birds nest, are composed of a mosaic of ice wedge polygons, non-patterned tundra, and large vegetated drained thaw lake basins. Regional climate projections suggest that evapotranspiration, rainfall, and snowfall will increase, making it difficult to predict how surface water distribution might change and how habitats for the invertebrate resources used by waterbirds will be impacted. This study will focus on evaluating how climate change will affect the invertebrate community, and whether the change in climate (through changes in hydrology and surface energy balance) could induce a trophic mismatch that might alter the growth and survival of shorebird young....
