Thunberg headlines NYC event in global climate strike

From New York City to Washington D.C. to Seattle to Los Angeles, Americans on Friday joined millions of students and workers to demand urgent action on climate change, part of a worldwide strike inspired by 16-year-old Swedish activist Greta Thunberg.

(SOUND BITE) (ENGLISH) CLIMATE ACTIVIST GRETA THUNBERG, SAYING:

"People are striking today in over 150 countries... And why? Because this is an emergency. Our house is on fire... And we will not just stand aside and watch. We are united behind the science, and we will do everything in our power to stop this crisis from getting worse, even if that means skipping school or work, because this is more important. Why should we study for a future that is being taken away from us?"

Thunberg, who sailed across the Atlantic in an emissions-free yacht to speak at next week's United Nations climate change summit, headlined a massive rally in Lower Manhattan.

Worldwide concern over global warming has escalated since U.S. President Donald Trump abandoned the international Paris Accord on climate change and took a series of steps to dismantle environmental protections including moving on Thursday to block stricter vehicle emissions standards in California.
