Join Jack Black as he meets with climate scientists at the University of Miami to analyze the possible effects of on the dense environment of South Florida.

Combined with strong hurricanes and , rise is even more threatening. In fact, maps with sea level projections for 2030, 2060, and 2100 show an increasingly uninhabitable Miami. cities all over the world are destined to face similar problems if people continue pumping into the atmosphere at present levels.

Transcript (English)

- [Jack] Who wouldn't wanna live here in Miami? It's beautiful. But is sea level rise something people here actually have to worry about? To find out, I've arranged to meet with a scientist named Keren Bolter. She lives in South Florida and says she'll give me the lowdown. Today she's introducing me to two of the top climate scientists in Florida, Ben Kirtman and Harold Wanless. So what are we looking at here?

- So here we go. This is what it looks like in 2030. Everything in red is gonna be underwater.

- Whoa.

- In 15 years, during the extreme tide in October, every high tide is gonna be this high. That's just 15 years from now. Now let's look at 2060. High tide in October. Areas that will be below sea level. It's uninhabitable.

- [Jack] I can't believe what I'm looking at. Whole parts of Miami gone? I had no idea it could be this bad. And so soon.

- And you know, a hurricane in October is absolutely not unheard of. That happens here. So now you have sea level rise and storm surge. Think about how much flooding they're gonna suffer during a major event.

- [Keren] If a storm surge hit in 2060, this is what's vulnerable. Once the sea level is that high.

- [Harold] And you're looking at less than 50 years in the future.

- I was in a movie called "Waterworlds" and it got really bad reviews, but now we can see that we were right. Can you show me on the map what the worst case scenario is for say 2100?

- The high projections for 2100 are 6.6 feet. When the tide is highest, everything in red will be underwater.

- [Jack] Whoa.

- [Keren] Yeah. The entire county.

- [Jack] There's no safe place.

- There's no more Miami.

- The port facilities compromised. The airports compromised. No fresh water resources.

- Also, you know, just because there's places that are above water, if there's no roads going to the place, it's essentially cut off from civilization.

- And that's what we're telling communities to plan for. We're not just looking at South Florida. This is a proxy for all the coastal areas of the world. The Mumbai's, the Shanghai's.

- Yeah.

- The Atlantic cities.

- There's gonna be like massive migrations of humanity moving to different parts of the world just to survive, right? I mean, we're talking about...

- It's gonna happen in the coming centuries because all of this carbon that we put into the atmosphere, it hasn't even started to make its impact, but there's such a time lag.

- The big urgency is that, every year we don't do anything. We're warming the ocean more, and it's that heat that's accelerating melting of ice. And that's the scary part.

- We need to start thinking about how we build and plan, not for the next five years, but for the next hundred years.

- [Jack] I really had no idea that all the carbon dioxide we've emitted will continue to do damage for decades. Raising the seas all around the world. What are the millions of people who live on the coast supposed to do?

Transcripción (Español)

- [Jack] ¿Quién no querría vivir aquí en Miami? Es hermoso. Pero, ¿es el aumento del nivel del mar algo de lo que la gente aquí realmente tiene que preocuparse? Para averiguarlo, he organizado una reunión con una científica llamada Keren Bolter. Ella vive en el sur de Florida y dice que me dará toda la información. Hoy me está presentando a dos de los principales científicos del clima en Florida, Ben Kirtman y Harold Wanless. Entonces, ¿qué estamos viendo aquí?

- Aquí vamos. Así es como se verá en 2030. Todo lo que está en rojo estará bajo el agua.

- ¡Guau!

- En 15 años, durante la marea extrema en octubre, cada marea alta será así de alta. Eso es solo dentro de 15 años. Ahora veamos el 2060. Marea alta en octubre. Áreas que estarán por debajo del nivel del mar. Es inhabitable.

- [Jack] No puedo creer lo que estoy viendo. ¿Partes enteras de Miami desaparecidas? No tenía idea de que podría ser tan malo. Y tan pronto.

- Y sabes, un huracán en octubre no es absolutamente inaudito. Eso sucede aquí. Entonces ahora tienes el aumento del nivel del mar y la marejada ciclónica. Piensa en cuánto inundación van a sufrir durante un evento importante.

- [Keren] Si una marejada ciclónica golpeara en 2060, esto es lo que está vulnerable. Una vez que el nivel del mar esté tan alto.

- [Harold] Y estás viendo menos de 50 años en el futuro.

- Estuve en una película llamada "Waterworlds" y recibió críticas muy malas, pero ahora podemos ver que teníamos razón. ¿Puedes mostrarme en el mapa cuál es el peor escenario para, digamos, el 2100?

- Las proyecciones altas para el 2100 son de 6.6 pies. Cuando la marea está más alta, todo lo que está en rojo estará bajo el agua.

- [Jack] Guau.

- Sí. Todo el condado.

- [Jack] No hay lugar seguro.

- No hay más Miami.

- Las instalaciones portuarias comprometidas. Los aeropuertos comprometidos. No hay recursos de agua fresca.

- Además, sabes, solo porque hay lugares que están por encima del agua, si no hay caminos que lleguen al lugar, está esencialmente aislado de la civilización.

- Y eso es lo que estamos diciendo a las comunidades que planifiquen. No solo estamos mirando al sur de Florida. Esto es un indicador para todas las áreas costeras del mundo. Los Mumbai, los Shanghái.

- Sí.

- Las ciudades del Atlántico.

- Va a haber migraciones masivas de humanidad moviéndose a diferentes partes del mundo solo para sobrevivir, ¿verdad? Quiero decir, estamos hablando de...

- Va a suceder en los próximos siglos porque todo este carbono que hemos puesto en la atmósfera, ni siquiera ha comenzado a hacer su impacto, pero hay un retraso tan grande.

- La gran urgencia es que, cada año que no hacemos nada, estamos calentando más el océano, y es ese calor el que está acelerando el derretimiento del hielo. Y esa es la parte aterradora.

- Necesitamos empezar a pensar en cómo construir y planificar, no para los próximos cinco años, sino para los próximos cien años.

- [Jack] Realmente no tenía idea de que todo el dióxido de carbono que hemos emitido continuará causando daño durante décadas. Elevando los mares en todo el mundo. ¿Qué se supone que deben hacer los millones de personas que viven en la costa?
