A 16-year-old girl has been nominated for the 2019 Nobel Peace Prize in recognition of her astonishing global campaign to protect the environment.
"Greta Thunberg has launched a mass movement in which I see, perhaps, the main contribution to peace".
Since then she has gone global, striking a chord with younger people disillusioned by the slow progress of the adult world in halting climate change.
If she were to win, she would be the youngest recipient since Pakistan's Malala Yousafzai, who was 17 when she received the prize.
"Honoured and very grateful for this nomination", Thunberg tweeted early Thursday morning.
She protested by sitting outside the Riksdag (Parliament) every day during school hours with a sign, "Skolstrejk för klimatet [School strike for climate]".
"I think we have reached a tipping point where enough scientists are telling it like it is and not being so afraid of being alarmist", Thunberg told New Scientist on Wednesday, adding it's been frustrating that many people are paying more attention to her age than the issue at hand.
So far, there have been regular walkouts around the world, including in countries likes Germany, Belgium, the UK, France, Australia and Japan.
The Nobel Peace Prize will be announced on October 11, 2019.
National politicians, worldwide officials, academics and previous winners are among those who can nominate potential recipients.
There are 301 candidates for the Nobel Peace Prize for 2019, out of which 223 are individuals and 78 are organisations, says the Nobel committee on its website.
How is the Nobel Peace Prize nominated and chosen?
The list of nominees is kept secret for at least 50 years, in line with the Nobel Foundation's statutes.
