00:00Now, you might want to book your dream vacation to Miami Beach as soon as you can, because

00:05this whole area might be underwater in the next 75 years.

00:10But it's not just Florida.

00:12Parts of Louisiana, California, and Washington are also expected to be among the first American

00:18states affected by sea level rise.

00:21If you live in the United States, you can check for yourself whether your address is

00:25on the list of cities that will disappear.

00:28Search for Sea Level Rise Viewer on Google.

00:31That will take you to a tool created by the National Oceanic and Atmospheric Administration.

00:36And it helps us visualize what coastal flooding might look like in the future.

00:40Now, you see that dark area in blue?

00:43Those are the sinking cities of the US.

00:46And by that, I mean cities that could be submerged by 2100.

00:50That's in the worst-case scenario, if ocean levels were to rise by as much as 10 feet.

00:55Hopefully, it won't come to that.

00:59As you probably know by now, sea levels are going up because the Earth is getting warmer.

01:04When the planet heats up, ice at the north and south poles melts.

01:09And all that extra water flows into the oceans.

01:11Plus, warmer water expands and takes up more space.

01:15So, between the melting ice and the expanding oceans, sea levels slowly rise over time.

01:21And that means more flooding and even the possibility of some cities ending up underwater.

01:27Right now, statistics show that sea levels are expected to rise by around 6 feet by the year 2100.

01:34The problem is that this could cause major coastal flooding, and not just during storms or heavy rains.

01:40Even on clear days, some areas could end up underwater.

01:44And that brings us to a question.

01:46How do we actually know how high ocean waters are?

01:51These days, experts can measure sea level with incredible accuracy, thanks to satellite altimeters.

01:57That's basically a special type of radar that measures how high something is.

02:02It figures out the height of the ocean by timing how long it takes for a radar pulse to travel

02:07from the satellite down to the surface of the sea and then bounce back.

02:12When scientists combine that data with the satellite's exact location, they can map even the tiniest

02:18changes in sea level all over the world.

02:21Right now, coastal flooding predictions are showing us something serious.

02:25The rate of global sea level rise has doubled over the past three decades.

02:30And there are plenty of tools online that help us to visualize just how big this problem could

02:34become in the future.

02:36The Sea Level Rise viewer I mentioned earlier focuses on areas within the United States.

02:42But if you don't live there, you can still check if your address might be in danger.

02:47Just look up the interactive map from Climate Central.

02:50If you set the water level to 10 feet above the high tide line, you'll see that a lot

02:55of countries could be seriously affected.

02:58Let's take a look at South America.

03:00In Argentina, for example, rising waters could flood many parts of Buenos Aires province.

03:06Head over to Brazil, and you'll see that a lot of cities, including Rio de Janeiro, would

03:11be affected.

03:13We might have to say goodbye to that iconic wave-patterned sidewalk along Copacabana Beach.

03:19And both of the city's airports would be flooded too.

03:22Things don't look much better in Europe.

03:25Major cities like Lisbon in Portugal, Valencia in Spain, and Rome in Italy could end up partly

03:30underwater.

03:31Honestly, the worst situation in Europe is probably in the Netherlands.

03:36Right now, about a quarter of the country is literally below sea level.

03:40And nearly half of it sits just three feet above.

03:44So if sea levels rise, they are facing some serious risks.

03:48This entire red zone, which includes cities like Amsterdam and Rotterdam, would be below

03:53the surface if the ocean rose by 10 feet.

03:57Fortunately, the Netherlands is probably the country with the most experience in fighting

04:02back against the sea.

04:03For years, they have tackled the threat with massive infrastructure.

04:07Things like giant canals, windmills, and dikes – all designed to manage the water.

04:12And thanks to their efforts, the Dutch have reclaimed about 20% of their land from the

04:17sea.

04:18That's right, they're actually expanding.

04:20Unfortunately, some countries are at much higher risk than others.

04:24According to estimates, about five of them are in serious danger of disappearing in the

04:29near future.

04:31First up is Fiji, a tropical paradise loved by tourists.

04:35This nation is in a tough spot because of its low-lying landscape.

04:39There, extreme warming could cause sea levels to rise by as much as 6 feet by the year 2100.

04:46It doesn't help the fact that Fiji sits right in the middle of the Pacific Ocean, where massive

04:51storms can quickly turn things into chaos.

04:55That means people there need to brace themselves for more frequent flooding, and they're already

05:00taking action.

05:01To protect against coastal erosion, some communities are lining the seashore with old tires to keep

05:07sand from washing away in stronger waves.

05:10Others are planting mangroves across the coast.

05:13These trees can reduce the height of waves hitting the shore by an average of 31%.

05:18Plus, they help cut down wind speeds, which really matters during cyclones.

05:25Next on the red list is Vanuatu.

05:27This chain of islands, located between Australia and Fiji, could be underwater sooner than we

05:33think.

05:34And they're already making changes.

05:36Vanuatu is one of the first Pacific nations to relocate an entire community to safer ground.

05:42Back in 2005, people living in vulnerable areas on the north island of Tegua moved to higher

05:47land.

05:49With temperatures continuing to rise, they're bracing for even more intense tropical cyclones.

05:54That means heavier rainfall, more flooding, and a much higher risk to both homes and infrastructure.

06:01The Marshall Islands are also facing a serious risk.

06:04This country is home to around 39,000 people and lives on the opposite side of the world from

06:10the United Kingdom.

06:11It's an extremely low-lying island nation built on what's basically a coral reef.

06:16According to NASA, sea levels there have risen by almost 4 inches over the past 30 years.

06:22And they could rise by about 7 and a half inches over the next 30.

06:27And that's no small thing.

06:28If nothing is done, the islands could face more than 100 days of flooding every year by

06:33the end of the century.

06:36People over there are afraid of losing their homes.

06:39Studies also show that up to 40% of the buildings in the capital city, Majuro, could end up underwater

06:45in the future.

06:46But this country isn't ready to give up, and they're reinforcing the infrastructure.

06:51The Solomon Islands are also being slowly swallowed by the sea.

06:55This region has been experiencing sea-level rise at nearly three times the global average.

07:01Over the years, satellite images have shown that five vegetated reef islands have already

07:06vanished beneath the waves.

07:08On the bright side, the people there are working hard to protect their homes.

07:12They're building stone walls along the coast and planting mangroves to hold back the water.

07:18But the worst case might be Tuvalu, as it could become the first country to turn completely

07:23uninhabitable because of rising seas.

07:26This island chain, located about halfway between Australia and Hawaii, sits only about 9 feet

07:32above sea level.

07:34And in its narrowest spot, in a place called Funga Fale, the land is just about 65 feet wide.

07:40You can see how vulnerable the situation is, right?

07:44I mean, even before the higher tides arrive, the country's limited farmland could be affected

07:49by saltwater.

07:50These islands are a powerful example of resilience.

07:54And a reminder that sinking cities don't have to mean disappearing ones.

07:58While the challenges are real, the global response to sea-level rise is growing stronger

08:03every day.

08:04Around the world, communities are adapting, innovating, and coming together to tackle the

08:09threat of rising water.

08:11That's it for today!
