Greta Thunberg Filmed Giving Donald Trump A Death Stare

If looks could kill, the United States would be searching for a new president.

Teen activist Greta Thunberg made waves on Monday evening after delivering a scathing and emotional speech at the United Nations climate action summit in New York.

She accused dozens of world leaders of burdening her generation with the extreme effects of climate change.

“This is all wrong," the 16-year-old said, her voice quivering. "I shouldn’t be up here. I should be back in school on the other side of the ocean yet you all come to us young people for hope. How dare you".

"You have stolen my dreams and my childhood with your empty words," she continued.

Thunberg's anger didn't appear to have hit boiling point until outside the forum when U.S. President Donald Trump strode past her without a glance.

He was on his way to a UN meeting about religious freedom after only attending the major climate summit for a few minutes.

As fate would have it, cameras picked up the entire exchange, or lack of, with the video quickly gaining traction on social media.

Many applauded the cold, cold death stare Thunberg gave Trump.

"Greta Thunberg is all of us," was the general feel online.

It's no secret that Thunberg isn't a Trump fan.

While she is behind the growing push for more action on climate change, particularly among the younger generations, Trump is a climate change denier who has undone almost all major U.S. regulations aimed at combating the climate change.

He's also vowed to withdraw America from the Paris climate accord, the main global climate pact.

Trump and Thunberg are both yet to comment on the incident.
