greenhouse gases

Leonardo DiCaprio's new documentary, "Before the Flood," has been on YouTube for just a few days, but it already has millions of views.

The documentary is a moving, uncompromising look at climate change, produced by both DiCaprio and National Geographic. In the documentary, DiCaprio, who's been an outspoken supporter of climate action, gives us a refreshing, very frank look at what the climate change situation is really like.

DiCaprio doesn't pull his punches on the big stuff, but what actually fascinated me were some of the smaller, simpler, more emotional moments.


"Before the Flood" is an hour and a half long, and I can't recommend watching it enough, mostly because of these five affecting, emotional moments that stayed with me once the movie was done.

1. The quiet moment when a researcher admits how much the natural world means to him.

All images are screengrabs from "Before the Flood"/National Geographic/YouTube.

Near the beginning of the film, DiCaprio goes up to Greenland to check out the glaciers and ice sheets. You'll get to see amazing footage of crevasses and ice floes, and he also does some really cool interviews, including one with a local hunter.

But one moment in this scene stands out: DiCaprio is standing with Dr. Enric Sala, a marine ecologist and National Geographic explorer, watching some narwhals come up before them. You can actually hear the whales click and purr.

Then, just at the end, Sala turns to DiCaprio and says, unbidden, "You know, I don't want to be on a planet without these animals."

2. The moment in Beijing that made me think about my own family.

A short while later, the crew is in Beijing talking to a Chinese woman who's holding an air mask in her hand. She explains what it's like to live surrounded by Beijing's legendarily bad air pollution, mentioning that her family puts on their masks when they step outside and feed the cat.

"When the air is bad it hurts my throat," the woman says.

The scene isn't as visually impressive as drone footage of smoke stacks or giant industrial machines, but it stuck with me all the same. It sounds like the kind of everyday comment someone in my family might make.

3. The moment when Sunita Narain called out DiCaprio's wishful thinking and told him to get real.

Later, DiCaprio goes to India to talk to Sunita Narain, an environmentalist and activist. About 30% of India — roughly 300 million people — still live with no electricity, so the discussion turns to how to bring power to people without resorting to fossil fuels.

If you're like me and like thinking about the nitty-gritty of climate change — not just the big goals but the hard truths and big questions — this is an amazing exchange. But the best part is when she calls out the U.S. for wanting India to move to renewables while the U.S. drags their feet.

"If it was that easy, I would have really liked the U.S. to move towards solar, but you haven't," Narain says. "Let's put our money where our mouth is."

It's real, uncompromising conversation and actually feels awesome. It's a "take that" to every simpering, milquetoast politician who's more concerned with firing up their base and talking pretty than getting results.

4. The moment I'll remember every time I watch a snowy movie from now on.

While they were filming "The Revenant," they actually had to have the snow trucked in. It was too warm. In fact, they ended up having to fly halfway around the world to frosty Argentina in order to continue filming.

I remember "The Revenant." I remember the snow and the cold and the biting frost of that film. To think of future movies having to truck in snow is just so ... weird. I'm not sure I'll be able to see any frozen, snowy landscape without wondering how much snow was there and how much had to be trucked in.

5. Finally, what might have been my favorite moment: when DiCaprio asked Obama a really uncomfortable question.

This is my favorite moment in the film by far.

"You are the leader of the free world," says DiCaprio. "You have access to information that most people do not. What makes you terrified for the future?"

Obama's answer? He waxes poetic about his kids for a moment, but when it comes down to it, he says, a huge amount of people live near the ocean. If the sea levels rise, those people will need to flee to somewhere — and that could be a problem.

"In very hard-headed terms, you've got to worry about the national security implications of this. And the capacity for the existing world order as we understand it to survive the kinds of strains that the scientists are predicting."

In truth, this movie is full of amazing moments. It was really hard to pick just five.

There were so many awesome scenes, like when DiCaprio visits the mayor of Miami Beach, which is already experiencing flooding, or when he feeds rescued orangutans in Indonesia and tried his Italian on Pope Francis.

But in the end, "Before the Flood" has two simple messages.

One, we have to consume differently. We need to think about where our food and lifestyles are coming from. In many ways, though, we're beyond the stage where simple actions can solve everything. So two, and perhaps more importantly, we all need to vote. We need world leaders who will invest in renewables and put taxes on carbon.

The final segment, by the way — where DiCaprio gives a speech to the United Nations — might be the most affecting. I found it hard to not tear up. But I'm not going to link to it because you really owe it to yourself to watch the whole movie.

For the first time in history, representatives of 195 nations agreed to dramatically reduce greenhouse gas emissions.

Rejoice! Hooray! The world is saved!

Well. Sort of. Ish. For now.

The so-called "Paris Agreement" was signed into effect Saturday evening, Dec. 12, 2015, after two weeks of grueling negotiations(and technically one day after what was supposed to have been the end of the Conference of the Parties, but that's OK).

It is a landmark step in slowing the effects of climate change across the globe. The mere fact that 195 nations actually came together and agreed on something is a pretty remarkable feat in itself, especially considering that the last 20 times the United Nations tried to get together to address global warming, all ended in resounding shrugs.

While the historical importance of this cooperation is certainly worth celebrating, it's also an easy distraction from the more ... lackluster aspects of the climate deal.

Imagine those 195 nations involved in the agreement are 195 friends who all went out for dinner one night.

Now imagine the nightmare of trying to split the bill 195 ways. The Democratic Republic of the Congo doesn't want to go in on the $300 bottle of wine that the United States bought for the table. And the Marshall Islands had two more pieces of calamari than Brazil did, so Brazil wants them to pay the difference. Then, of course, there's Monaco, who only got a salad and yes OK paid for exactly what they ate plus a stingy tip, but they didn't factor in the tax and everyone else wants them to split the cost of the appetizers, too. And we haven't even gotten started on entrees yet!

Let's just say there was a lot of compromise involved. But hey, at least everyone had a good time, right?

For example, there was a whole lotta hemming and hawing about the difference between a 1.5° and 2°C global temperature increase.

We know the overall climate is warming and we need to stop it before it gets worse. But there's some disagreement on what "worse" means, exactly.

The general consensus has been that 2 degrees Celsius is the cutoff for rising global temperatures by the end of the century. Any hotter than that, and it gets increasingly difficult to predict just how unpredictable the ecological damage could be. Also, 2 degrees seemed like a pretty attainable goal for most countries.

There are others, however, who were pushing to cap the rise at 1.5 degrees. And while that half-degree might seem like splitting hairs, there are some parts of the world where it could be the difference between life and death.

The result of all this back-and-forth? The global temperature increase will be capped at ... um ... well, we're gonna cap the global temperature increase.

Basically, every country gets to set its own limits for greenhouse gas emissions. These limits will be publicly available through the UN website so all nations can be held to proper public scrutiny.

Unfortunately, there's not really any requirement for these emission reductions other than "less than what we're doing now." Amid the fancy legalese of the formal agreement, it actually says: "Parties aim to reach global peaking of greenhouse gas emissions as soon as possible" (emphasis mine).

That's remarkably vague and noncommittal, especially for a legally binding contract. But the parties will reconvene every five years to review their progress and maybe-possibly increase those limits. So that's something?

The upside of the Paris Agreement: Everyone agrees that we need to take climate action.

Even if specific action is still left to the discretion of each nation, this is a big move in the right direction.

While the issue of global warming is hardly "solved" and we're not any closer to saving the planet once and for all (if such a thing is even possible), at least we acknowledge there's a problem, and we're committing to fix it.

Yes, there are some changes that will happen in your country and some things that might be integrated into your day-to-day lives. But you might not even notice them, and they might not be enough to make a difference.

That might seem like cold comfort. But it all depends on what we do from here on out.

So let's pledge as individuals to embrace climate-conscious lives whenever possible.

Vote with your dollars and go green when you can. You don't have to buy solar panels for your home — just pay attention to what you recycle. Walk, bike, or carpool when you can (and maybe next time you buy a car, aim for electric). Be aware of the world as you move through it, and consider the impact that actions might have on the future of our planet. And whenever there's an option that involves less fossil fuels, I implore you to take it.

That might be as vague and noncommittal as the Paris Agreement. But everything has to start somewhere.

Let's get started.
