TikTok may be better known for short lip-sync, comedy and viral challenge videos. But some young users of the social video app are taking on a bigger issue - climate change - through make-up and time-lapse videos.
TikTok videos with the hashtag #globalwarming have so far garnered 50.8 million views.
Some of the more creative videos try to depict the impact of climate change on people and the environment through the use of special effects make-up.
British teenager Hana Martin is behind one such video. At the start of the 15-second clip, her face and neck are painted a vibrant shade of blue, depicting an ocean teeming with marine life, including fish and a dolphin.
Halfway through the video, the make-up design on her body is replaced by one that shows a sea of toxic waste, rubbish and a giant turtle wrapped in plastic.
The clip has garnered more than 430,000 likes.
Hana, 16, a student from South Wales, said she started producing TikTok videos on climate change less than a month ago. She usually spends about two hours putting on the make-up.
She was inspired by other young people supporting the cause, such as Swedish teenager Greta Thunberg, who, at age 15, began protests outside the Swedish Parliament about the need for immediate action to fight climate change.
"I am conscious that a vast majority of my audience is at an age where they can potentially be influenced by social media," Hana told The Sunday Times.
"I, therefore, wanted to try to influence and educate them as positively as I can on relevant social topics," said the teenager, who has also produced videos on topics such as anti-bullying.
"I feel that younger people are more likely to listen to other younger people, not politicians whom they can't relate to."
Her ocean clip has attracted more than 2,200 comments.
"We need to help out the earth. You could give five minutes of your life to clean up the world," one user commented.
Another pointed out: "Yes we do need to do something but I wish people would make videos on HOW."
While not all comments were positive, Hana is taking the criticism in her stride. She said: "Even the hate I sometimes get can be seen as positive. When someone comments 'global warming isn't real', another will rubbish that theory and it triggers a debate, getting them thinking about the topic. "
Time-lapse videos are also popular among TikTok users spreading the climate change message.
One such video posted by TikTok user Anna Bogomolova begins with the year 2019, with things looking seemingly rosy. As it progresses, it shows Ms Bogomolova suffering from the impact of climate change, such as rising temperatures. The video ends with the year 3019, with Ms Bogomolova holding a piece of plastic she had coughed up. The clip has attracted 2.3 million likes.
The 21-year-old, who is from Russia but is now studying in London, told the BBC: "Other generations started this problem but we can't say we won't be alive to see the consequences."
PICTURE-PERFECT NDP FIREWORKS, CAPTURED BY READERS
Civil servant David Sim, 48, was one of them. Mr Sim, who was at the boardwalk outside Marina Bay Sands with his five-year-old son, shared several nice shots captured with his 360-degree camera.
"We've never had the chance to ballot successfully for the NDP tickets, so every year for the last nine years, we would try to catch the NDP proceedings and fireworks from the fringes of the venue," he told The Sunday Times. "This year's fireworks were absolutely stunning, especially the low-flying ones."
Russian Angelika Dotcenko, who shared two pictures taken near the Esplanade using a camera and phone, saw NDP fireworks for the first time. Ms Dotcenko is married to a Singaporean and has been living here for 21/2 years. "It was amazing," said the 27-year-old restaurant manager.
