What If All Ice Melted in One Hour?

[00:00:00]What if every glacier and ice sheet melted in the next 60 minutes? [music] Antarctica, Greenland, all of it.

[00:00:05]Imagine what happens next. All that water pours into the [music] ocean, raising sea levels by 70 m. Coastlines vanish, and entire countries slip underwater. Most coastal cities wouldn't survive. New York, London, Shanghai, Miami, gone beneath the waves [music] as the oceans reclaim the land. The planet would redraw its map. New inland seas would form, and higher regions like Denver [music] would become the new coasts. Earth holds 5 million cubic miles of ice. Melting it naturally takes thousands of years, but in 1 hour, everything changes. [music] If this happened today, our cities and our world would be transformed forever. This is the power of our planet.
