Meanwhile, young Swedish climate activist Greta Thunberg delivered an emotional speech at the UN Climate Action Summit... making headlines across the globe.
She slammed world leaders for failing to tackle climate change.... saying that young people will "never forgive them" if they don't act on their promises.
Kim Da-mi has the story.
Through tears and visible frustration, the 16-year-old activist Greta Thunberg blasted world leaders for failing to save the world against the climate crisis.
Her message was direct and powerful that it's wrong that world leaders come to young people for hope... when they're missing out on school to fight against a global catastrophe.
"How dare you. You have stolen my dreams and my childhood with your empty words. We are in the beginning of a mass extinction, and all you can talk about is the money and fairy tales of eternal economic growth."
Thunberg then pointed out how the world has ignored the crisis, noting that the science has been crystal clear for over 30 years.
She said world leaders weren't meeting their promises.
"You say you hear us, and that you understand the urgency, but no matter how sad, and angry I am I do not want to believe that, because if you really understood the situation and still kept on failing to act, then you would be evil, and that I refuse to believe."
Urging the world not to fail young advocates, the teenager highlighted there will be no forgiveness and the world is waking up.
Over the past year, young activists have staged scattered climate strikes in solidarity with her Fridays for Future Movement.
Another strike is scheduled to be held on Friday in New York with thousands of students expected to take part.
