00:00 This is a question I've been thinking about all my life.
00:03 What if all the world's ice melted?
00:08 I mean, think about it.
00:13 What if a dramatic surge of climate change
00:17 melted all the world's ice overnight?
00:20 Would you wake up to find yourself drowning underwater?
00:24 How much of your country will be submerged?
00:28 This is what if, and here's what would happen
00:32 if all the world's ice melted.
00:35 Have you ever noticed how an ice cube melts
00:42 in a glass of water that's filled to the brim?
00:45 How does it change the water level?
00:48 The truth is, it doesn't.
00:51 Above or below the water line,
00:53 a melted ice cube replaces exactly the same volume of water.
00:58 Now let's add salt to the mix.
01:01 In the case of a one cubic inch ice cube,
01:04 the water level in the glass will rise 0.03 cubic inches.
01:09 Now that's a fairly small amount, right?
01:12 But what if you apply this to glaciers and floating sea ice?
01:16 5.8 million square miles of our planet is covered in ice.
01:22 If all of that was to melt overnight,
01:26 the global sea level would rise 230 feet.
01:31 All seven continents would be partially underwater.
01:37 There would be no more Miami, no London.
01:40 The coast of Australia will be washed out
01:43 along with 80% of its residents,
01:46 and so would Venice and the Netherlands.
01:49 Things wouldn't be that bad for Africa,
01:51 but with the extreme heat wave that would follow,
01:55 most of the continent would be uninhabitable.
01:58 You think the floods would wash out humanity entirely?
02:01 Well, not all of it,
02:03 but whoever is left would have plenty of dangers
02:06 to deal with because you see,
02:07 all that melted ice would release carbon dioxide
02:11 into the air.
02:12 Given that the oxygen content in the atmosphere
02:15 would remain the same,
02:16 you would start choking trying to breathe the air,
02:21 and you would have very little time
02:23 to acclimatize to this new world.
02:25 Ocean currents would change,
02:27 thereby affecting the sea life,
02:30 and with no time to adapt to these extreme changes,
02:33 our sea creatures and polar animals
02:36 would face mass extinction.
02:38 The ones still alive would have to leave their home
02:41 and find a new place to live.
02:44 This would result in a decrease in the human food supply.
02:48 A change in the sea current
02:49 would also mean dramatic weather changes.
02:52 Heavy rainfall would hit the deserts,
02:55 and areas with significant rainfall would dry out.
02:59 Wind patterns would change too.
03:01 Oceanic hurricanes would occur more frequently,
03:04 causing more floods.
03:06 Even the smallest earthquake off the coast
03:09 could devastate nearby regions,
03:12 causing a massive tsunami.
03:14 All of this would cause a global migration
03:17 that no government would be able to deal with.
03:20 The world as we know it would collapse.
03:24 Luckily, all the ice can't melt overnight,
03:29 but unfortunately, it is melting.
03:33 Even the oldest ice core is melting.
03:38 That has been storing all of Earth's climate information
03:41 for 1.5 million years.
03:44 If we keep adding fuel to the fire
03:50 that is climate change,
03:51 in only 5,000 years,
03:54 the Earth will be ice-free.
03:57 Peace.
