Without a strong current like AMOC, our climate will change significantly. The slowdown alone will lead to drought in Africa’s Sahel region, which is a transition area between Sahara and savanna. It also means more water will stay near the eastern seaboard, meaning area-specific sea level rise. It also means more heat waves, especially for Europe.
