00:00What if all the ice on Earth melted?
00:02Imagine Antarctica becomes bear land, Greenland loses its ice, and the Arctic turns into open
00:07ocean.
00:08This would cause global sea levels to rise by 66 meters.
00:11New York would be underwater, and Florida would be almost completely gone.
00:15Parts of Los Angeles and San Francisco would become islands, and the entire east coast
00:19of South America would vanish.
00:21In Europe, the Netherlands and Denmark would risk disappearing, while parts of the UK
00:24would sink under rising waters.
00:26Venice would vanish completely, while Barcelona and Rome would face partial flooding.
00:30In Asia, entire megacities — Tokyo, Hong Kong, Bangkok — would be partially underwater,
00:35and Bangladesh would almost completely disappear.
00:38The entire coastline of Africa would change dramatically, just like Australia's, where
00:42megacities would vanish as if they had never existed.
00:45But that's just the beginning.
00:46Without ice to reflect sunlight, Earth would heat up fast, sparking wildfires, droughts,
00:51and floods.
00:52The Gulf Stream would weaken, sending Europe into the cold, while Africa dries out.
00:56All glaciers would melt, and that could cause a global freshwater shortage.
