An overview of major scientific findings and local observations about climate change in Nunavut. Changes to the Arctic include: glacier retreat, sea-ice and lake-ice thinning, permafrost thawing, coastal erosion from wave action, changes in ocean currents, and shifting ranges of plant and animal species. The timing, nature and severity of impacts on Nunavut communities are difficult to predict and will be different from place to place. Like many nations across the globe, Nunavut is trying to reduce GHG emissions in response to climate change. A main focus for Nunavut is promoting adaptation to the new conditions that have come with climate change. This means adjusting planning, decisions, and activities for the expected impacts of climate change. In the short term, neither mitigation nor adaptation actions alone can stop negative climate change impacts. However, taking adaptive action will minimize harm to people and communities. Changes in Temperature Over the last 100 years, the Ar...
