JUDY WOODRUFF: A growing number of Americans are worried climate change is a real crisis.
That is one of the findings of a new poll by The Washington Post and the Kaiser Family
Foundation.
It found that eight in 10 Americans believe human activity is fueling climate change,
and nearly 40 percent now consider it a crisis, a significant jump from just five years ago.
Yet fewer than 40 percent also believe that they will have to make major sacrifices to
tackle the problem.
But young people across the world are now mobilizing to push for urgent action.
William Brangham spoke today with the Swedish teenager who's helped galvanize this movement.
Our story is part of a special initiative called Covering Climate Now, a global collaboration
of more than 250 news outlets to enhance coverage of the climate story.
PROTESTER: What do we want?
PROTESTERS: Climate action!
PROTESTER: When do we want it?
PROTESTERS: Now!
WILLIAM BRANGHAM: The younger generation came to the White House today demanding that the
grownups inside stop acting like children.
They said, acknowledge that climate change is a crisis and act accordingly.
Among the crowd was 16-year-old Greta Thunberg from Sweden.
In the past four years, Thunberg, who has mild autism, has helped drive this youth climate
movement.
She repeatedly called out world leaders for their climate inaction, like here at the U.N.
Climate Change Conference in Poland.
GRETA THUNBERG, Climate Activist: We have come here to let them know that change is
coming, whether they like it or not, the people who rise to the challenge.
And since our leaders are behaving like children, we will have to take the responsibility they
should have taken long ago.
WILLIAM BRANGHAM: And here, at the World Economic Conference, the yearly gathering of the wealthy
elite in Davos, Switzerland.
GRETA THUNBERG: At places like Davos, people like to tell success stories, but their financial
success has come with an unthinkable price tag.
And, on climate change, we have to acknowledge that we have failed.
WILLIAM BRANGHAM: Across Europe, Thunberg has helped spur demonstrations that are called
Fridays For Future, where schoolkids leave class to draw attention to climate change.
Thunberg arrived in the U.S. last month after crossing the Atlantic on a solar-powered sailboat.
She won't fly because of air travel's carbon output.
She's participating in climate events leading up to the United Nations General Assembly
in New York next week, where climate activists are planning mass rough protests on Friday.
I sat down with Thunberg today, and begin by asking her how she first learned about
climate change.
GRETA THUNBERG: I was completely unaware of everything, like everyone else.
And I learned about this in school.
And I learned the basics, that the planet was warming because of increased greenhouse
gas emissions, and that would lead to -- that the global temperature would rise, there would
be more extreme weather, and so on.
And I just thought that, if it's really as serious as they are saying it is, then why
isn't it being discussed more?
Why isn't it being a higher priority?
So I started to read about it more and more.
And then I started to understand how acute it actually was and is.
WILLIAM BRANGHAM: Why do you think it is?
Because a lot of other people read those same studies and understand those same facts, and
yet they don't see it as the crisis that you see it as.
Why do you think other people don't appreciate it that way?
GRETA THUNBERG: I don't know.
Many people seem to have this double moral that they say one thing and then do another
thing, that they say the climate crisis is very important, and yet they do nothing about
it, and like cognitive dissonance.
WILLIAM BRANGHAM: Cognitive dissonance.
GRETA THUNBERG: Yes.
And if I know something, if I want to do something, then I go all in and I, like, walk the walk,
walk the talk, because I want to practice as I preach.
WILLIAM BRANGHAM: You have helped galvanize young people all over the world to care about
this.
Do you have a sense as to why young people in particular have so embraced this movement?
GRETA THUNBERG: It is probably because we are the ones who are going to be affected
by this crisis the most.
And, for many, it seems so distant, but, for us, it seems less distant, because we are
the people who are going to live in the future.
We are the future.
We are those who are going to have to adapt from this crisis.
And so that's why I think a lot of people seem threatened about this, a lot of the young
people, more than adults.
WILLIAM BRANGHAM: There is seemingly so much evidence around us.
We see wildfires, droughts, heat waves, intensifying storms, melting in the Arctic and the Antarctic,
extinction of species.
And yet, as we were discussing, the evidence is there before us, but it does seem that
the sense of urgency is not as intense as you feel it ought to be.
And I'm just curious why you think that is.
GRETA THUNBERG: I mean, of course, it could be many different things, but I think it is
because humans are social animals.
We follow the stream.
And since no one else is behaving like this was a crisis, then we see that and we think,
then I should probably behave as they do.
But...
WILLIAM BRANGHAM: Just go on with life as usual.
GRETA THUNBERG: Yes.
But, for me, I have -- I am on the autism spectrum, and I don't usually follow social
coding.
And so that's why I go my own way.
And I think that is a very strong reason why people just continue, because they don't see
anyone else reacting to this.
WILLIAM BRANGHAM: You think your autism in some sense has given you an insight into this
or a way to act in response to this that others may not have?
GRETA THUNBERG: That could be, definitely.
WILLIAM BRANGHAM: As you know, we have a president here in the United States, who seems dismissive
of the science of climate change, and a political party, a major political party, that goes
along with that.
He pulled out of the Paris climate accords.
But even the nations that did acknowledge the severity of the problem and signed on
to the Paris accord, even those nations are really not living up to their commitments.
So, given that, why do you have hope that we will, as a global society, react?
GRETA THUNBERG: I think that people are good.
People are not evil, at least not everyone, most people.
And so I think people are just simply unaware of the situation and people are not feeling
the urgency.
I think that, once we would start treating this crisis as an emergency, people will be
able to grasp the situation more.
All these climate movements that have played out during the last year or years is proof
of that.
I don't think anyone could have predicted the school strike and Friday For Future movement
to become so big, and many other movements as well.
WILLIAM BRANGHAM: You took a solar-powered boat to come here, because I know you're trying
to reduce your own carbon footprint by not flying at all anymore.
Is there a concern that, if people are too focused on individual actions, like eating
less meat or not flying as often, that they might be distracted from the much larger policy
changes that you're talking about?
Is that a worry that you have?
GRETA THUNBERG: Of course, that we focus on these isolated problems, that we talk about
people need to eat less meat or something, if people focus on that, and then someone
else says, no, it's much more effective if everyone stops flying and so on.
And then someone says, no, we need to -- to...
WILLIAM BRANGHAM: Drive electric cars.
GRETA THUNBERG: Yes, or shut down the coal power plants.
And -- but we need to focus on all of these things.
And, of course, individual change doesn't make much difference in a holistic picture,
but it influences others around you.
We need both system change and individual change.
WILLIAM BRANGHAM: If people are listening to you, what one thing would you like them
to take away from this?
What one thing would you like them to do?
GRETA THUNBERG: Everyone can make a huge difference.
We shouldn't underestimate ourselves, because if -- if lots of individuals go together,
then we can accomplish almost anything.
So, that's what I want people to take out from this.
WILLIAM BRANGHAM: Greta Thunberg, thank you very much.
GRETA THUNBERG: Thank you so much.
