Climate activist Howey Ou, 17, poses for a portrait at her hotel in Guilin.
While most of her peers are preparing for university or enjoying summer vacation, 17-year-old Howey Ou is braving intimidation and criticism in China to save the world from climate catastrophe.
Young environmental activists around the world have skipped school to attend marches in protest at global inaction over climate change.
But in China, grassroots social movements are heavily suppressed by the government, and the movement is severely lacking in participants.
It has changed Ou's life though. She was inspired by Swedish teenage climate campaigner Greta Thunberg, and held her own week-long solo protest in May last year outside her local government buildings, gaining international recognition.
While Thunberg has addressed global leaders at the UN Climate Action Summit and received awards for her work, the Chinese activist has been kicked out of school for refusing to give up her campaigning.
Known as Ou Hongyi in China, she has also faced run-ins with police, family pressure, and harsh online criticism.
But the teenager says it is her "life mission" to sound the alarm before it is too late.
She told AFP that although she "wasn't scared of the police", her parents were under pressure from authorities.
After her protest outside the government offices, she started planting trees in the surroundings of Guilin, the southern Chinese city where she lives, and studied methods of non-violent protest, poring over the works of Mahatma Gandhi.
She has also tried to recruit more young people to join her cause, but most of the time she is a lone figure, carrying hand-painted placards as people walk by, oblivious.
'Never oppose the government'
As her campaigning attracted more attention, Ou chose to move out of her family home -- highly unusual for a minor in China -- and now lives alone at a hostel in Guilin.
Her parents worry about her safety, and her father is anxious that she may be lagging behind her peers due to start university.
Ou, however, insists she is not trying to go against authorities, and sees it instead as "a question of morality".
Ou has thousands of followers on social media but has struggled to find wider support within China. Last summer she travelled solo around the country on a shoestring, meeting with environmental NGOs and activists.
But she says many had little understanding of the climate crisis -- and the journey formed the loneliest period of her life.
Then last October, she faced criticism from millions online when a German media interview with her went viral on Chinese social media.
Many accused her of attention-seeking and "armchair activism", while others made unflattering comparisons to Thunberg, who is a frequent object of ridicule on the Chinese internet.
She avoided social media for several months after that.
During the hardest moments, Ou says she drew comfort and strength from the spectacular natural scenery in her hometown -- something she has enjoyed since childhood.
Researchers from Cambridge University, the University of East Anglia and London-based SOAS looked at a "realistic scenario" known as RCP 8.5, where carbon and other polluting emissions continue rising in coming decades.
Now to collect data that can help presage drastic weather changes and keep people abreast of research in climate change, Air New Zealand is converting one of its domestic aircraft into a flying environmental monitor as part of a world-first project with Nasa.
Greta Thunberg has said that the world needs to learn the lessons of coronavirus and treat climate change with similar urgency.
Researchers warned of 26 Earth "tipping points" such as melting ice sheets, that have the potential to unleash a domino effect of irreversible catastrophes across the planet.
The UN body said that "the Iftar practice is typically transmitted within families, and children and youth are often entrusted with preparing components of traditional meals."
