Atlantic's 'Heat Valve' May Be Failing, Threatening Global Climate Stability

Beneath the Atlantic's surface, a vast circulatory system has quietly governed the climate of entire continents for millennia — and new research suggests it may be failing. The Atlantic Meridional Overturning Circulation, which carries warmth northward and cold water south, shows signs of slowing under the pressure of melting ice and rising ocean temperatures, with some scientists projecting a potential collapse by 2060. Such a shift would not merely alter weather patterns but would reorganize the conditions under which billions of people grow food, build cities, and imagine their futures. Hum
