Over the past few decades, the Arctic has warmed at about twice the rate of the rest of the globe. The impact of this on the Arctic’s physical systems, biological systems, and human inhabitants is large and projected to grow throughout this century and beyond.
This fact sheet details the largest issues facing the Arctic as a result of climate change, including the melting of permafrost and the subsequent release of methane and CO2, and provides an overview of how they negatively impact Arctic vegetation and the ability for Arctic species to survive.
This fact sheet focuses on the effects of new species migrating to the area and creating competition for food and possibly importing new parasites and diseases. In addition, migratory birds arriving to the Arctic from non-Arctic areas will experience the disappearance of their stop-over nesting sites as a result of rising sea levels.
