Climate change exerts indirect effects on human health in Alaska through changes to water, air, and soil and through ecosystem changes affecting disease ecology and food security, especially in rural communities.Īlaska’s rural communities are predominantly inhabited by Indigenous peoples who may be disproportionately vulnerable to socioeconomic and environmental change however, they also have rich cultural traditions of resilience and adaptation. Each of these will have different manifestations for Alaskans when compared to residents elsewhere in the United States. The influence of climate change on human health in Alaska can be traced to three sources: direct exposures, indirect effects, and social or psychological disruption. Longer sea ice-free seasons, higher ground temperatures, and relative sea level rise are expected to exacerbate flooding and accelerate erosion in many regions, leading to the loss of terrestrial habitat in the future and in some cases requiring entire communities or portions of communities to relocate to safer terrain. Degradation of permafrost is expected to continue, with associated impacts to infrastructure, river and stream discharge, water quality, and fish and wildlife habitat. As temperature and precipitation increase across the Alaska landscape, physical and biological changes are also occurring throughout Alaska’s terrestrial ecosystems.
The use of multiple alternative models to appropriately characterize uncertainty in future fisheries biomass trajectories and harvests could help manage these challenges. Climate change will likely affect management actions and economic drivers, including fisheries, in complex ways.
Ocean acidification is an emerging global problem that will intensify with continued carbon dioxide (CO 2) emissions and negatively affects organisms. While many opportunities exist with a changing climate, economic prospects are not well captured in the literature at this time.Īs the climate continues to warm, there is likely to be a nearly sea ice-free Arctic during the summer by mid-century. This includes the dissemination of several tools, such as guidebooks to support adaptation planning, some of which focus on Indigenous communities. Although climate change does and will continue to dramatically transform the climate and environment of the Arctic, proactive adaptation in Alaska has the potential to reduce costs associated with these impacts. The cost of infrastructure damage from a warming climate is projected to be very large, potentially ranging from $110 to $270 million per year, assuming timely repair and maintenance. Alaska is often identified as being on the front lines of climate change since it is warming faster than any other state and faces a myriad of issues associated with a changing climate.
