These reporters tried to goad Greta Thunberg. She wasn’t having any of it.

Greta Thunberg has hit reporters with a dose of her signature sarcasm, laughing off mocking questions about her activism.

After a visit to the World Economic Forum in Davos, the 20 year old activist walked around the outskirts of the Swiss ski resort.

She was surrounded by a crowd of journalists, several of whom posed jeering questions.

One reporter said: "It's been quite cold in Davos, when can I expect some global warming?"

Another asked: "Who was filming your arrest in Germany? Because it looked like you did that in several takes, didn't you?"

The reported from Rebel News was referring to Thunberg's detention alongside other activists on Tuesday during protests against the demolition of a village to make way for a coal mine expansion. She was released after an identity check, according to police.

Thunberg answered with a laugh. "It's very likely that the German police and [mine owner] RWE fossil fuel company would stage arrests," she said sarcastically.

What has Greta Thunberg said about the WEF?

The World Economic Forum (WEF) - an international organisation of public and private entities - meets annually in Davos, Switzerland.

The world’s elite descend on the small alpine town to discuss global issues and potential solutions.

But Thunberg expressed pessimism about the WEF's role in climate action.

"It has not led us anywhere specifically good, has it?" she said.

"These are the people who are in charge, the people who own the wealth, who are investing in fossil fuels. And yet, they are the ones we expect to solve the climate crisis when it’s people who are affected by it that we should be listening to".

Speaking at a Davos meeting, Thunberg urged International Energy Agency Executive Director Fatih Birol to stop the global energy industry and the financiers who support them from fuelling carbon investments.

Thunberg has joined with other activists to present a "cease and desist" letter to CEOs, calling on them to stop opening new oil, gas and coal extraction sites.

"As long as they can get away with it they will continue to invest in fossil fuels, they will continue to throw people under the bus," she warned.
