How will warming in the Arctic affect the rest of the world?
Climate change in the Arctic is expected to affect other parts of the world. The melting of ice masses in the Arctic could contribute significantly to global sea-level rise, and the addition of that fresh water to the salty oceans could change global ocean circulation patterns. Arctic tundra also stores huge amounts of carbon, which could be released to the atmosphere during a thaw, further enhancing the greenhouse effect and global warming.
