The city of Kivalina, Alaska and the Native Village of Kivalina have filed a lawsuit against multiple oil and power companies. The lawsuit claims that the greenhouse gases emitted by these companies have contributed to global warming factors that have caused great trouble for the city and its people. Sea ice which normally protects the community from big storms has been forming later and melting earlier due to the rising temperatures, which has also caused great amounts of erosion. Due to the limited sea ice, storms have also been battering the coast line and the city itself. City Administrator Janet Mitchell said, "We are seeing accelerated erosion because of the loss of sea ice. We normally have ice starting in October, but now we have open water even into December so our island is not protected from the storms." Exxon Mobil Corporation, one of the main targets in the suit, declined comment until it could completely review the complaint. Some of the other companies named in the suit include: Chevron, ConocoPhillips, BP PLC, Peabody Energy, Duke Energy, DTE Energy and Shell Oil.
