  • Hi, I'm Bill Patzert.

  • I spent more than 50 years at NASA's Jet Propulsion Laboratory studying climate change and global warming.

  • Much of what the public really knows about climate change and global warming comes from Hollywood.

  • Today we're going to dissect a few films and see where Hollywood gets it right and wrong.

  • Day After Tomorrow.

  • Global warming has melted the polar ice caps.

  • We do not act soon, it is our children and our grandchildren who will have to pay the price.

  • But they got the science wrong.

  • What we saw in New York City, the oceans rise, it's exceptionally photogenic.

  • But the size is totally unrealistic.

  • It's too immediate, global warming gets you slowly.

  • This instantaneous switch into a mini Ice Age over a few days, the time scale's all wrong.

  • We're not cooling.

  • We're warming.

  • The scientist played by Dennis Quaid dramatically draws a line across the center of the United States.

  • Everyone south of that line.

  • It's not the way it happens.

  • But there are a lot of things I liked about it.

  • Couple of ironic things.

  • One of them is mass migration out of the United States.

  • And they are wading across the river illegally into Mexico.

  • There will be mass migrations as we look into the 21st century.

  • In particularly in the American southwest.

  • Now one of the things they really got wrong is one of the least likely places in the world to have devastating tornadoes is southern California.

  • Day After Tomorrow, they played for the camera, not for the science.

  • Let's give it a C minus.

  • Our next film is 2012.

  • Massive solar eruption impacts the core of the earth.

  • Setting off a geologic catastrophe in the crust, essentially destroying civilization.

  • It's definitely a dud!

  • Global warming has almost no impact on the earth's crust.

  • It's a surface manifestation.

  • These are two different animals.

  • San Andreas fault is shifting.

  • Here in California, one of the big forces of nature that hangs over all our heads here is the San Andreas Fault.

  • It's moving, it's powerful, and potentially very destructive.

  • But it's totally decoupled from climate change.

  • On a popcorn scale, we're gonna give it an A plus.

  • But on a science scale, it's a D minus.

  • Interstellar really asks the core question.

  • As population explodes, as we change our climate, as we devastate our ecosystems, what is the future of mankind on planet earth?

  • And it's interesting how they use the past as a metaphor for the future.

  • Expanding droughts.

  • You didn't expect this dirt that was giving you this food to turn on you like that and destroy you.

  • Starvation on a mass scale.

  • We ran out of food.

  • The world needs farmers.

  • Good farmers.

  • Nelson's torching his whole crop.

  • He's saying it's the last harvest for okra.

  • Ever.

  • The thing that really gets you is not sea level rise, it's the lack of water and the lack of food due to over-population.

  • Six billion people.

  • Just try to imagine that.

  • And every last one of them trying to have it all.

  • How does the human race deal with that?

  • And if we don't wanna repeat of the excess and wastefulness of the 20th century, then we need to teach our kids about this planet.

  • We're not meant to save the world.

  • We're meant to leave it.

  • There's not a planet in our solar system that could sustain life.

  • Or any nearby solar system.

  • Big question, great flick, an A plus.

  • Mad Max, although it paints a grim picture of a post-apocalyptic future, there's something very contemporary about it.

  • I am your redeemer!

  • It is by my hand you will rise from the ashes of this world!

  • The fundamental resource essentially that sustains civilization, which is water, is being controlled by a megalomaniac who's misogynistic.

  • Totally lacking empathy for the people that he rules.

  • There is something really prophetic about Mad Max.

  • We see the rise of dictators across the planet and resources become more and more limited, most of the earth has turned into a desert.

  • Now we're seeing that on a smaller scale today.

  • You'll not, my friends, become addicted to water.

  • We will take hold of you and you will resent its absence.

  • I'm giving this movie an A plus on many levels.

  • Myself, I'd go back and look at this many many times.

  • I think the message from all these movies:

  • We have to be careful who we vote for.

  • We have to wean ourselves off fossil fuels and onto renewable energies.

  • This is the home planet.

  • There is no planet B.
