An intense metal version of Greta Thunberg's iconic speech is being widely shared online and may have even inspired the climate change activist to pursue a musical career.
The 16-year-old's impassioned plea at the United Nations Climate Change Summit last week was remixed by YouTuber 'John Mollusk', who added backing track and redid the speech with guttural metal vocals.

In just a few days, the clip has clocked up over 3.2 million views and shared by many on social media - including Thunberg herself.
"I have moved on from this climate thing... from now on, I will be doing death metal only!" she jokingly tweeted.
The YouTuber's real name is John Meredith, according to Rolling Stone, who interviewed the drummer for thrash metal band Suaka.
"When I saw her speech, I was very impressed by her passion and outrage," Meredith told Rolling Stone.
"The words she chose just evoked the darkness of the metal music I love: Entombed, Gojira, At the Gates, Sepultura."
Thunberg's speech indeed makes for very metal lyrics: "You have stolen my dreams and my childhood with your empty words. And yet I'm one of the lucky ones. People are suffering. People are dying. Entire ecosystems are collapsing. We are in the beginning of a mass extinction."
Meredith's video has received some backlash - not so much the grumpy attacks on Thunberg that have dominated news coverage, or those leaping to her defence, but rather the metal subgenre it claims.
"I've seen soooo many comments, saying: 'This is not Swedish Death Metal'," Meredith says.
"It's probably more black metal maybe but the title is also a nod to her country of origin. It's like that Viking fury can’t be denied. In general, genres are for critics; musicians just make music they like."
