Understanding climate change impacts on Arctic ecosystems and associated climate feedbacks

Climate change is altering Arctic ecosystems and biodiversity. These changes feed back to the climate system, with a potential to dampen or accelerate local to regional changes in climate and greenhouse gas emissions.

Objective

The resulting impacts on ecosystem services, livelihoods and well-being will have far-reaching consequences for Arctic communities and beyond. The objective of this activity is to assess how climate change affects Arctic ecosystems and climate feedbacks to inform strategies for adaptation and resiliency.

The objective of this activity is to assess how climate change affects Arctic ecosystems and climate feedbacks to inform strategies for adaptation and resiliency. The work will address how:

  • Climate change impacts fundamental ecosystem properties and trigger ecosystem perturbations. Emphasis will be on how climate change could erode resilience, making Arctic ecosystems more prone to abrupt changes and tipping points, as well as changes over longer time periods. Assessments will encompass marine, coastal, freshwater, and terrestrial ecosystems;
  • The capability of ecosystems to regulate climate, which are impacted by climate induced changes. This entails feedbacks related to a range of mechanisms, including storage and release of carbon, hydrological fluxes, and surface albedo; and,
  • Climate-induced changes impact Indigenous Peoples, local communities and livelihoods, and how ecosystem-based adaptations could reduce the vulnerability of Indigenous Peoples and local communities to impacts.

 

 

Activities

  • Step 1 Preparatory Activities (2021): Co-design and prepare a detailed plan describing the topics, relevance, available datasets, methods, case studies and assessment products;
  • Step 2 Implementation (2021-2023): Products might include reports, scientific articles, special journal issues, policy-summaries, and communication products; and,
  • Step 3 Follow-up (2023-2025): Joint AMAP/CAFF science assessment and Summary for Policy Makers.
