Greta Thunberg

"Our voices are not being heard, our voices are being left behind," said Ugandan advocate Evelyn Acham.

"In broad daylight," warned Greta Thunberg, "we are being gaslit by corporates and governments but we are exposing the climate lies."

"There is still time to avoid the worst consequences if we are prepared to change. It will take determined, visionary leadership. And it will take immense courage—but know that when you rise, billions will be right behind you."

"So much for 'building back better' and a 'green recovery,'" said youth climate leader Greta Thunberg.

"We have immense power," said United Nations Secretary-General António Guterres. "We can either save our world or condemn humanity to a hellish future."

While Uganda's Nakate said humanity "cannot adapt to extinction," Thunberg from Sweden said lack of action is "a betrayal of all present and future generations."

"The climate crisis has not disappeared," said Swedish activist Greta Thunberg. "It's the opposite—it's even more urgent now than it was before."

Youth activists are demanding not only climate action but also equitable Covid-19 vaccine distribution.
