Swedish environmental activist Greta Thunberg is returning to school after a year off, she announced on Twitter on Monday.

"My gap year from school is over, and it feels so great to finally be back in school again!" the 17-year-old wrote.

Thunberg commenced her first year of high school a few days after her peers in Stockholm, who returned after summer vacation last week, as she was in Germany to meet Chancellor Angela Merkel and also lead a climate strike in Berlin.

The teenager had spent the past year off school dedicated to the fight against climate change, starting in August 2019 with a trip via boat to New York to take part in a UN climate summit, where she repeated the phrase "how dare you" to condemn world leaders in a widely-viewed speech.

Nominated for a Nobel Prize

Thunberg met with climate activists across Europe and the Americas during the year and was nominated for a Nobel Peace Prize.

Previously, she began a global movement to draw attention to climate change by skipping school on Fridays and staged her first school strike in August 2018.
