A sweeping account of how the Arctic became the next arena of global conflict as the great powers battle over trade routes, resources, and military dominance from Greenland to Siberia—by award-winning Financial Times journalist Rana Foroohar.

As polar ice melts and new sea routes open, the Arctic has become the most consequential—and least understood—geopolitical theater in the world. In Sea Change, Rana Foroohar takes readers aboard America’s only Arctic icebreaker and inside the halls of power in Washington, Beijing, Moscow, and allied capitals to reveal how climate change is reshaping global trade, national security, and industrial policy.

Drawing on unprecedented access to Coast Guard missions, senior officials across multiple administrations, labor leaders, and international partners, Foroohar shows how being a strong sea power is vital and how the U.S. is struggling to catch up. She also explains how control of Arctic shipping lanes, shipbuilding capacity, underwater data cables, and untapped natural resources will determine economic and military supremacy in the decades ahead. Both a gripping voyage and a clear‑eyed analysis of global power, Sea Change argues that America’s future prosperity and security may well be decided at the top of the world.
