Arctic rising (2012)

"The Arctic Ice Cap has all but melted, and the international community is racing to claim the massive amounts of oil beneath the newly accessible ocean. Enter the Gaia Corporation. Its two founders plan to terraform Earth to save it from itself--but in doing so, they may have created a superweapon the likes of which the world has never seen. Anika Duncan, a pilot for the United Nations Polar Guard, finds herself caught up in a plot by military agencies and corporations who want the Gaia Corporation stopped. But when Gaia loses control of its superweapon, it will be Anika who has to decide the future of the world."--Publisher's description.
