Scientists discover world’s largest waterfall — but It’s completely invisible, here’s why

Scientists have identified the Denmark Strait cataract, an underwater waterfall between Greenland and Iceland, as the world’s largest. Plunging 11,500 feet, it dwarfs Angel Falls and moves 3.2 million cubic meters of water per second. This hidden cascade plays a crucial role in regulating Earth’s climate by driving the Atlantic Meridional Overturning Circulation, but climate change threatens its stability.
