The United States President Donald Trump, who has in the past described climate change as a hoax, has mocked a 16-year-old climate activist after her moving speech at the UN.
The US president posted a seemingly sarcastic tweet about the teen while quoting a particularly emotional line from Greta Thunberg's address to the Climate Action Summit.
In the tweet, shared to his over 64 million followers, Trump suggested the Swedish teen looked happy and excited about the future, unlike what she had stated at the summit.
"She seems like a very happy young girl looking forward to a bright and wonderful future. So nice to see," said Trump.
In her emotional and charged speech, Greta had reprimanded those who she accused of ignoring science and being too slow in their approach to tackle world's contributions to climate change.
A tearful Greta told world leaders gathered at the climate action summit in New York that her childhood dreams had been stolen by empty promises of eternal economic growth.
"We are in the beginning of a mass extinction and all you can talk about is money and fairytales of eternal economic growth," said Greta.
Trump, who was expected to skip the climate summit on Monday, September 23, made a surprise visit for about 15 minutes and Greta could be seen glaring at the president as he walked past her.
Trump has been working to pull the US out of the 2016 Paris climate agreement, arguing that it will put the country at a competitive disadvantage.
Greta is reported to have sailed across the Atlantic in a yacht to attend the event attended by China, India, France, Germany and the UK, while Brazil and Saudi Arabia stayed away.
UN Secretary-General Antonio Guterres ruled that countries would only be allowed to speak at the summit if they brought plans to reduce carbon emissions.
