The other part of me wonders if that's just your Viking heritage.

It might be?

Yeah.

Tell me why you did that.

Why didn't you fly to New York City to come and, you know, speak at the U.N.

and, you know, inspire people to move forward in the climate change movement?

I mean, I know I wouldn't do that as a kid, and I wouldn't do it now.

But what is inspiring is your determination.

And what's inspiring is that it doesn't just affect other young people.

It started to affect older generations in Sweden, in Germany.

People are starting to call it the Greta effect, where people are taking more trains.

Since you started this movement, they've said they feel ashamed to fly unnecessarily in Europe.

Your mom is an opera singer.

and she stopped flying, which means she couldn't perform the way she used to.

Do you sometimes feel bad that she can't perform, or are you more excited that she's not part of, I guess, polluting the planet?

And the planet is the most important thing for you.

Why... Why do you think... Why do you think young people are so focused on climate change now?

There's a definite, um, disconnect between older generations and younger generations when talking about the climate.

Why do you think that is?

What do you think people need to learn about climate change?
