Teen climate activist Greta Thunberg gave back after President Donald Trump dismissed her TIME person of the year award. Trump joined Brazilian President Jair Bolsonaro & Russian President Vladimir Putin on the list of world leaders who recently patronized the 16-year-old when he reacted to her Time honour. "So ridiculous," 73-year-old Trump tweeted. Thunberg, who has shot to global fame since launching her "Fridays For Future" climate crisis protests, had a quick reply. Putin described her in September as "kind," before adding dismissively that "no one has explained to Greta that the modern world is complex.” Thunberg soon changed her Twitter bio to: "A kind but poorly informed teenager.” Greta Thunberg is a teen activist from Sweden who has urged immediate action to address a global climate crisis. She was named recently named Time’s Magazine’s Person of the Year for 2019.
