Arctic now locked into devastating temperature rise, UN report says

The Arctic is now locked into a destructive degree of climate change regardless of what measures are taken to halt global greenhouse gas emissions. Under current rates of carbon dioxide emissions, the report anticipates Arctic summer sea ice could largely disappear within two decades. The melting of Arctic glaciers and the Greenland ice cap will increase sea levels and affect global ocean currents and weather patterns, while thawing permafrost is expected to contribute to increased carbon dioxide and methane emissions.
