Greta Tintin Eleonora Ernman Thunberg (Swedish pronunciation: [ˈɡrêːta ˈtʉ̂ːnbærj] ; born 3 January 2003) is a Swedish environmental activist known for challenging world leaders to take immediate action to mitigate the effects of human-caused climate change. Thunberg's climate activism began when she persuaded her parents to adopt lifestyle choices that reduced her family's carbon footprint. In August 2018, aged 15, Thunberg began skipping school, vowing to remain out of school until after a Swedish election to attempt to influence the outcome.
