Greta Thunberg rang in Halloween in the best possible way: trolling climate change deniers.
Rather than donning a spooky costume, she took aim at her haters. Posting a photo on Twitter of herself alongside a placard which reads "skolstrejk för klimatet", the 16-year-old captioned the tweet, "So today is Halloween. I don't celebrate it back home, but I thought I might give it a try. And apparently when it comes to scaring a bunch of angry climate crisis deniers - I don't even have to dress up!! #trickortreat."
Watch Greta Thunberg rebuke world leaders in her rousing UN speech:And the post garnered quite the reaction on social media. "You're terrific! The youth of today need leaders like you. Keep it up, stay strong!" wrote one fan, while another corroborated "LOL so funny because it's true. Hopefully, the hospitals won't be flooded with deniers suffering severe shock."
"Nothing is more terrifying to those in power than a smart young person using their voice to address systemic problems," added a third.
Another wrote: "Especially rich mean old men. You’re their worst nightmare!!"
Earlier this week, Thunberg was praised for her activism after winning the Nordic Council's annual environment prize, which boasts a $75,000 cash reward.
She chose to turn it down, however, asserting that such prizes don't do anything to help the planet. "I am currently traveling through California and therefore not able to be present with you today. I want to thank the Nordic Council for this award. It is a huge honour," Thunberg wrote on Instagram.
"But the climate movement does not need any more awards. What we need is for our politicians and the people in power start to listen to the current, best available science. The Nordic countries have a great reputation around the world when it comes to climate and environmental issues."
