SNAP provides several platforms for looking at historic climate trends and climate projections in Alaska and western Canada:
1. Downloadable datasets for historic climate data and projected climate data (temperature and precipitation).
2. Interactive map - provides climate projections for Alaska and western Canada for each decade through 2100. User can choose what variables, time periods, seasonal averages, and emissions scenarios they’d like to view.
SNAP provides climate projections (temperature and precipitation) for Alaska and western Canada, using an ensemble of climate models (GCMs) and 3 emissions scenarios. Information is presented in a variety of formats.
U.S. forests play a large role in offsetting carbon emissions, about 20 % of the U.S. fossil fuel carbon output. If a forest replaces itself after a disturbance like fire, then there is no long-term loss of carbon.
Three major biomes intersect in the south-central region of Alaska: the western edge of the coastal rainforest, the southern edge of the boreal forest, and the eastern edge of the mostly treeless tundra and shrub ecosystems of southwest Alaska. Predictions of climate change responses for these ecosystems vary widely and substantial vegetation changes in this area will have large impacts on the area economy. This study will evaluate tree species' vulnerability to climate change in this area of AK.

In the spring of 2012, the Chugach National Forest began a climate vulnerability assessment that provided a good outlet for presenting results from this project on potential migration of tree species in the south-central Alaska region. Tara Barrett and Robert Pattison participated in the workshop for this assessment at the University of Alaska Anchorage and worked with other participants to outline a chapter in the assessment focused on vegetation change in relation to climate in south-central Alaska. Researchers created a climate envelope model of the three spruce species in the region (Picea sitchensis, Picea glauca, and Picea mariana) and provided results of the model to the vegetation/wildlife group both in a written summary and in an informal presentation. A literature review on migration potential is near completion.

Researchers from the PNW Research Station and the Department of the Interior examined options for monitoring ecoregional-level change in northern latitudes. Climate-related changes to Alaska’s forests that could be monitored include changes in abundance and rarity of vascular plants, wildlife habitat, invasive species, fire risk, fire effects, postfire succession, impacts on forest growth and mortality from insects and diseases, and alterations in carbon pools and fluxes. Although managers of individual parks and refuges often have specific needs that require more targeted monitoring, regional level monitoring can help provide context for changes observed within smaller areas.
