Climate activist Greta Thunberg has been named TIME magazine's Person  the Year for 2019. The 16-year-old  Sweden beat New Zealand's Prime Minister Jacinda Ardern and the Hong Kong democracy protestors to win the award. Ms Thunberg shot to fame  2018  raising people's awareness  the threat to the planet  climate change. She started a global movement when she decided to go  a climate strike outside the Swedish parliament in August 2018. Schoolchildren  the world then followed her example. She has since addressed the United Nations  New York and has met the Pope. After hearing  the award, she tweeted: "Wow, this is unbelievable! I will share this great honour."
Greta Thunberg is the youngest person ever to receive the award. TIME magazine wrote about why it gave the prize to Ms Thunberg. It said she has, "succeeded  creating a global attitudinal shift"  getting millions of people to join a "worldwide movement calling  urgent change". It added: "Greta has offered a moral call to those who are willing to act, and put shame  those who are not." Not everyone is happy  Ms Thunberg receiving the award. Donald Trump Jr said TIME was using a teenager "as a marketing gimmick".  contrast, Hillary Clinton tweeted: "I am grateful  all she's done to raise awareness  the climate crisis, and her willingness to tell hard, motivating truths."
