What tweet did Greta Thunberg delete? End of the world claim controversy explored

Greta Thunberg, the environmental activist, has caused a stir on Twitter yet again, this time not for posting something but rather for deleting a tweet. Several people are sharing snips of Greta's deleted 2018 tweet where she said that climate change will wipe out all humanity unless we stop using fossil fuels over the next five years. Social media users were not pleased as she deleted her old tweet, calling her a fraud for doing so.

In 2018, Greta shared an article by gritpost.com, in which it was detailed that Harvard University professor James Anderson had warned that humanity might not exist if the use of fossil fuel does not stop within five years.

She shared the tweet by saying:

"A top climate scientist is warning that climate change will wipe out all of humanity unless we stop using fossil fuels over the next five years."Notably, the website gritpost.com where this article was posted, does not exist anymore.
