  Greta Tintin Eleonora Ernman Thunberg was born on 3 January 2003, in Stockholm, Sweden, to opera singer Malena Ernman and actor Svante Thunberg. Her paternal grandfather was actor and director Olof Thunberg. As explained by The Week, "with a thespian father" and singer mother, "it is perhaps unsurprising that has a slightly unusual name.... Thunberg shares her second name with the adventuring creation of Belgian cartoonist Georges Remi, better known as Hergé." She has a younger sister, Beata.
  
  I was diagnosed with Asperger's syndrome, OCD and selective mutism. That basically means I only speak when I think it's necessary. Now is one of those moments.
  
  Thunberg says she first heard about climate change in 2011, when she was eight years old, and could not understand why so little was being done about it. The situation depressed her, and as a result, at the age of 11, she largely stopped talking, severely restricted her eating, and lost ten kilograms (22 lb) in two months. Eventually, she was diagnosed with Asperger syndrome, obsessive–compulsive disorder (OCD), and selective mutism. In one of her first speeches demanding climate action, Thunberg described her selective mutism as meaning she "only speaks when necessary".
  
  Thunberg struggled with depression for almost four years before she began her school strike campaign. When she started protesting, her parents did not support her activism. Her father said he did not like her missing school but added: " respect that she wants to make a stand. She can either sit at home and be really unhappy, or protest and be happy." Her diagnosis of Asperger's syndrome was made public nationwide in Sweden by her mother in May 2015, in order to help families in similar situations. While acknowledging that her diagnosis "has limited before", Thunberg does not view her Asperger's as an illness, and has instead called it her "superpower". She was later described as not only the best-known climate change activist, but also the best-known autism rights activist. In 2021, Thunberg said that many people in the Fridays for Future movement are autistic, and very inclusive and welcoming. She thinks that the reason so many autistic people become climate activists is that they cannot look away, and have to tell the truth as they see it: "I know lots of people who have been depressed, and then they have joined the climate movement or Fridays for Future and have found a purpose in life and found friendship and a community that they are welcome in." She considers the best things that have resulted from her activism to be friendships and happiness.
  
  For about two years, Thunberg challenged her parents to lower the family's carbon footprint and overall impact on the environment by becoming vegan, upcycling, and giving up flying. She has said she showed them graphs and data, but when that did not work, she warned her family that they were stealing her future. Giving up flying in part meant her mother had to abandon international ventures in her opera career. Interviewed in December 2019 by the BBC, her father said: "To be honest, didn't do it to save the climate. She did it to save her child, because she saw how much it meant to her, and then, when she did that, she saw how much grew from that, how much energy she got from it." Thunberg credits her parents' eventual response and lifestyle changes with giving her hope and belief that she could make a difference. Asked in September 2021 whether she felt guilty about ending her mother's international career, she was surprised by the question: "It was her choice. I didn't make her do anything. I just provided her with the information to base her decision on." The family's story is recounted in the 2018 book Scenes from the Heart, updated in 2020 as Our House Is on Fire: Scenes of a Family and a Planet in Crisis, with contributions from the girls, and the whole family credited as authors.
