Greta Tintin Eleonora Ernman Thunberg (Swedish: [ˈɡrêːta ˈtʉ̂ːnbærj]; born January 3, 2003) is a Swedish activist who urges governments to take action on climate change and social issues. She became well-known worldwide in 2018, at age 15, after starting a school strike by herself outside the Swedish parliament. This action inspired the global Fridays for Future movement.

As the school strike movement grew, Thunberg became a well-known figure through speeches, protests, and participation in climate demonstrations in Europe and other regions. She has spoken to political leaders, taken part in major climate events, and been widely covered by international media. Her work has received both support and criticism. She has also expanded her focus to include human rights and global justice, expressing support for Ukraine, Palestine, Armenia, and Cuba. In 2025, she joined a humanitarian flotilla going to the Gaza Strip twice. This action received attention and caused political discussions worldwide.

Thunberg is credited with starting the "Greta effect," which increased awareness of environmental issues and youth activism. Supporters believe her work raised public attention to climate challenges and youth involvement in activism. Critics have questioned her statements, methods, and role in political debates. Thunberg has stated that her actions are based on published climate research and policy goals. She has received many honors, including being named to Time’s list of 100 Most Influential People and receiving the title Person of the Year in 2019.

Early life

Greta Tintin Eleonora Ernman Thunberg was born on January 3, 2003, in Stockholm, Sweden. Her parents are Malena Ernman, an opera singer, and Svante Thunberg, an actor. Her paternal grandfather was Olof Thunberg, an actor and director. According to The Week magazine, Greta’s father is a thespian and her mother is a singer, which may explain why she has a unique name. Her second name, Tintin, is shared with a character from a comic book created by Belgian cartoonist Georges Remi, also known as Hergé. Greta has a younger sister named Beata.

Greta first learned about climate change in 2011, when she was eight years old. She was troubled by the lack of action on the issue. At age 11, she stopped speaking for long periods, limited her food intake, and lost 10 kilograms (22 pounds) in two months. She was later diagnosed with Asperger syndrome, obsessive–compulsive disorder (OCD), and selective mutism. In one of her early speeches, she explained that selective mutism means she only speaks when necessary. She struggled with depression for nearly four years before beginning her school strike campaign. Initially, her parents did not support her activism. Her father said he did not like her missing school but added, “We respect that she wants to make a stand. She can either sit at home and be really unhappy, or protest and be happy.”

Greta said, “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.” Her mother shared her diagnosis with the public in Sweden in May 2015 to help other families. Greta acknowledges that her diagnosis limited her in some ways but sees it as a “superpower.” She is now widely known as both a climate change activist and an autism rights advocate. In 2021, she noted that many people in the Fridays for Future movement are autistic and that the group is inclusive and welcoming. She believes that autistic people often become climate activists because they feel a strong need to speak out and share the truth. She said that joining the movement has helped many people find purpose, friendship, and a sense of belonging.

For about two years, Greta encouraged her parents to reduce their family’s carbon footprint and environmental impact by becoming vegan, upcycling, and avoiding air travel. She showed them graphs and data, but when that did not work, she told her family they were stealing her future. Giving up air travel meant her mother had to stop taking international trips for her opera career. In 2019, Greta’s father told the BBC, “To be honest, [her mother] 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 [Greta] grew from that, how much energy she got from it.” Greta said her parents’ lifestyle changes gave her hope that she could make a difference. When asked in 2021 if she felt guilty about her mother’s career changes, Greta said, “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 told in the 2018 book Scenes from the Heart, which was updated in 2020 as Our House Is on Fire: Scenes of a Family and a Planet in Crisis. The book includes contributions from the family, and all family members are listed as authors.

Activism

In August 2018, Greta Thunberg began organizing school climate strikes and giving public speeches. These actions made her a well-known climate activist worldwide. During an interview with Amy Goodman of Democracy Now!, Thunberg explained she had the idea for a climate strike after seeing how some students in the United States refused to return to school following school shootings in February 2018. These students, from Marjory Stoneman Douglas High School in Parkland, Florida, later organized the March for Our Lives to support stronger gun control laws. In May 2018, Thunberg won a climate change essay contest held by the Swedish newspaper Svenska Dagbladet. She wrote, "I want to feel safe. How can I feel safe when I know we are in the greatest crisis in human history?"

After her essay was published, Thunberg was contacted by Bo Thorén from Fossil Free Dalsland, a group working to address climate change. Thunberg attended some of their meetings. At one meeting, Thorén suggested that students could strike to raise awareness about climate change. Thunberg tried to persuade other young people to join her, but few were interested. Eventually, she decided to hold the strike alone.

On August 20, 2018, Thunberg, who had just started ninth grade, decided not to attend school until the 2018 Swedish general election on September 9. Her protest began after Sweden experienced extreme heat waves and wildfires during its hottest summer in at least 262 years. She demanded that the Swedish government reduce carbon emissions as required by the Paris Agreement. For three weeks, she sat outside the Riksdag (Sweden’s parliament) during school hours with a sign that read "Skolstrejk för klimatet" ("School strike for climate").

Thunberg said her teachers had mixed opinions about her missing class. She explained, "As people, they think what I am doing is good, but as teachers, they say I should stop."

After Thunberg posted a photo of her first strike day on Instagram and Twitter, others began sharing her cause online. High-profile youth activists helped spread her message. On the second day, more activists joined her. A representative of the Finnish bank Nordea shared one of Thunberg’s tweets with over 200,000 followers. Local reporters covered her actions, and within a week, her story received international attention.

A Swedish climate-focused social media company called We Don’t Have Time (WDHT), founded by Ingmar Rentzhog, played a role in spreading her message. Rentzhog posted Thunberg’s photo on his social media accounts and shared a video on the company’s YouTube channel. He later asked Thunberg to become an unpaid youth advisor to WDHT. Without her knowledge or permission, Rentzhog used her name and image to raise money for a WDHT subsidiary. Thunberg said she received no money from the company and ended her volunteer role once she learned about the fundraising.

Throughout 2018, Thunberg’s activism expanded. She participated in demonstrations across Europe, gave public speeches, and used social media to mobilize supporters. In December, after the 2018 Swedish general election, she continued her strikes but only on Fridays. Her actions inspired students worldwide to join her Friday school strikes. In December alone, over 20,000 students participated in strikes in at least 270 cities.

Thunberg spoke out against the National Eligibility cum Entrance Test (Undergraduate) 2020 and Joint Entrance Examination 2020 exams in India, which were held in September 2020. She said it was unfair for students to take exams during a global pandemic. She also mentioned that Indian students had been deeply affected by floods in states like Bihar and Assam, which caused widespread damage.

On February 3, 2021, Thunberg tweeted her support for the 2020–2021 Indian farmers’ protest. Hindutva nationalists in Delhi burned effigies of her in protest against the farmers’ movement. The Indian government, led by the Bharatiya Janata Party, criticized her tweet, calling it an internal matter. In her initial tweet, Thunberg shared a document with advice on supporting the farmers’ protest, including hashtags and petitions. She later deleted the tweet, saying the document was outdated, and replaced it with a new one to help people understand the situation better. Disha Ravi, an Indian climate activist who edited the toolkit, was arrested on February 16, 2021, on charges of sedition and criminal conspiracy.

Thunberg’s speech at the 2018 United Nations Climate Change Conference (COP24) became widely shared online. She said the world leaders present were "not mature enough to tell it like it is." In early 2019, she joined student protests across Europe and spoke at various forums and parliaments. At the January 2019 World Economic Forum, she said, "Our house is on fire." She addressed the British, European, and French parliaments, though some right-wing politicians in France boycotted her. Pope Francis met with Thunberg briefly and encouraged her to continue her activism.

By March 2019, Thunberg still held weekly protests outside the Swedish parliament every Friday, with other students occasionally joining her. Her father said her activism did not affect her schoolwork, but she had less free time. She graduated from lower secondary school with excellent grades: 14 A’s and three B’s. In July 2019, Time magazine reported that Thunberg was taking a "year off from school" to travel in the Americas while meeting people from the climate movement before attending the 2019 United Nations Climate Change Conference (COP25).

In August 2019, Thunberg sailed across the Atlantic Ocean from Plymouth, England, to New York City in a 60-foot (18-meter) racing yacht called Malizia II. The yacht had solar panels and underwater turbines to make the trip carbon-neutral. The journey took 15 days, from August 14 to 28, 2019. France 24 reported that some crew members would fly to New York to return the yacht to Europe. Thunberg said she chose sailing to show that there is no real sustainable way to travel across oceans. While in the United States, she gave a short statement to the US House Select Committee on the Climate Crisis on September 18 instead of testifying. She submitted the IPCC Special Report on Global Warming of 1.5 °C as evidence.

This is all wrong. I shouldn’t be up here. I should be back in school on the other side of the ocean. Yet you all come to us young people for hope. How dare you! You have stolen my dreams and my childhood with your empty words. And yet I’m one of the lucky ones. People are suffering. People are dying. Entire ecosystems are collapsing. We are in the beginning of a mass extinction, and all you can talk about is money and fairy tales of eternal economic growth. How dare you!

Position on climate change

Thunberg explains that humanity is facing a serious crisis caused by global warming, which could threaten life on Earth. She believes that the baby boomers and each generation after them are responsible for causing and continuing harmful changes to the Earth's climate. She uses strong comparisons, like "our house is on fire," to show how urgent the situation is. She often speaks directly to business and political leaders, pointing out their lack of action to address the problem.

Thunberg says that climate change will affect young people the most, as their future will be greatly harmed. She argues that her generation may lose their future because leaders have prioritized making money over protecting the environment. She also states that people in the Global South, who have contributed the least to climate change, will suffer the most from its effects. She supports young activists in developing countries who are already dealing with the damage caused by climate change. In Madrid in December 2019, she said, "We talk about our future, they talk about their present."

At international meetings, Thunberg criticizes world leaders for not taking enough action to reduce emissions. She says that simply lowering emissions is not enough; emissions must be reduced to zero to keep global warming below 1.5°C. In April 2019, she told the British Parliament that using the word "lowering" instead of "stopping" emissions is a major reason why little progress is made. She urges politicians to listen to scientists, not her, for guidance on solving the crisis. Political scientists Mattia Zulianello and Diego Ceccobelli describe Thunberg's ideas as technocratic ecocentrism, which values scientific opinions highly.

Thunberg argues that the goals set in the Paris Agreement are not enough to limit warming to 1.5°C. She says that greenhouse gas emissions must start decreasing sharply by 2020, as outlined in the IPCC's 2018 report on global warming of 1.5°C. In February 2019, she told the European Economic and Social Committee that the EU's plan to cut emissions by 40% by 2030 is not enough to protect children's future. She believes the EU must reduce emissions by 80% instead.

In November 2020, Thunberg said that leaders set long-term goals but avoid taking immediate action. She criticized the European Green Deal, which aims to make the EU carbon neutral by 2050, for giving a false impression that real action is being taken. She said, "Nature doesn't bargain, and you cannot make deals with physics."

In July 2020, Thunberg and other activists wrote an open letter to EU leaders, urging them to make ecocide an international crime at the International Criminal Court. In June 2023, she called the destruction of the Kakhovka dam in Ukraine by Russia an ecocide and demanded that Russia be held accountable.

Before the 2021 United Nations Climate Change Conference (COP26) in Glasgow, Thunberg said she was not optimistic about the event achieving real progress. She said leaders would make promises but take no real action, only symbolic steps. She called Chinese President Xi Jinping "a leader of a dictatorship" and said democracy is the only solution to the climate crisis because public pressure is needed to drive change.

On October 30, 2021, Thunberg arrived in Glasgow for COP26. She spoke at protests and marched in a climate strike on November 5. She described COP26 as a failure, using phrases like "blah blah blah" and "greenwashing" to criticize empty promises and misleading actions.

Public response and impact

In February 2019, 224 academics signed an open letter supporting Greta Thunberg and the students who organized climate strikes. These academics, including scientists, showed strong support for Thunberg’s efforts, which is very different from the criticism she often faces from politicians.

Thunberg has met with many world leaders but said she cannot think of any politician who has impressed her. When asked about New Zealand’s Prime Minister Jacinda Ardern, who called the climate crisis a life-or-death issue, Thunberg said, “It’s funny that people believe leaders like Jacinda Ardern are climate leaders. That shows how little people understand about the climate crisis.” Thunberg focuses on actions, not words, saying, “Emissions have not decreased. These people are not taking action.” In fact, New Zealand’s greenhouse-gas emissions increased by 2% in 2019.

United Nations Secretary-General António Guterres supported the climate strikes led by Thunberg. He said, “My generation has failed to respond properly to the climate crisis. This is deeply felt by young people. No wonder they are angry.” At an event in New Zealand in May 2019, Guterres said his generation was “not winning the battle against climate change” and that young people must “rescue the planet.”

In 2020, U.S. presidential candidates like Kamala Harris, Beto O’Rourke, and Bernie Sanders supported Thunberg after her speech at a climate summit in New York. German Chancellor Angela Merkel said young activists like Thunberg pushed her government to act faster on climate change.

Thunberg and her campaign have faced criticism from some politicians. These critics have made personal attacks and said she oversimplifies complex issues. Among them were Australian Prime Minister Scott Morrison, German Chancellor Angela Merkel, French President Emmanuel Macron, Russian President Vladimir Putin, OPEC, and U.S. President Donald Trump.

In September 2019, Trump shared a video of Thunberg speaking to world leaders and included her quote: “People are dying, entire ecosystems are collapsing. We are in the beginning of a mass extinction.” Trump wrote, “She seems like a very happy young girl looking forward to a bright and wonderful future. So nice to see!” Thunberg changed her Twitter bio to match his description and said she could not understand why adults would mock children for speaking about science. In December 2019, Trump again mocked Thunberg after she was named Person of the Year by Time magazine. He tweeted, “So ridiculous. Greta must work on her Anger Management problem, then go to a good old fashioned movie with a friend! Chill Greta, Chill!” Thunberg responded by changing her bio to: “A teenager working on her anger management problem. Currently chilling and watching a good old fashioned movie with a friend.” During the 2020 U.S. presidential election, Thunberg replied to Trump’s tweet “Stop the count!” with: “So ridiculous. Donald must work on his Anger Management problem, then go to a good old fashioned movie with a friend! Chill Donald, Chill!”

In October 2019, Putin described Thunberg as a “kind girl and very sincere” but said she was being used by others. He criticized her for not understanding the complexity of the modern world, saying, “No one has explained to Greta that people in Africa and Asia want to live as wealthy as in Sweden.” Thunberg updated her Twitter bio to reflect Putin’s description. In December 2019, she tweeted: “Indigenous people are literally being murdered for trying to protect the forest from illegal deforestation. Over and over again. It is shameful that the world remains silent about this.” When asked about this, Brazilian President Jair Bolsonaro said, “Greta said that the Indians were dying because they were trying to protect the Amazon. It is impressive how the press gives voice to such a brat.” Thunberg changed her Twitter bio to “pirralha,” the Portuguese word for “brat” used by Bolsonaro.

In May 2019, Time magazine reported that Thunberg said it was “hilarious” when critics only mocked her or talked about her appearance, because it showed they had no real arguments. Former U.S. Vice President Joe Biden responded to Trump’s mockery of Thunberg by tweeting: “What kind of president bullies a teenager? @realDonaldTrump, you could learn a few things from Greta on what it means to be a leader.”

In March 2021, European Commissioner for Climate Action Frans Timmermans said the European Union remains committed to making its agricultural policies meet the goals of the European Green Deal.

In August 2019, Scott Walsman wrote in Scientific American that critics of Thunberg have made personal attacks, criticized her for being autistic, and used unfair arguments to reduce her influence. Aditya Chakrabortty wrote in The Guardian that some columnists and bloggers have made “ugly personal attacks” on Thunberg. British TV presenter Piers Morgan also mocked her. Germany’s right-wing party Alternative for Germany (AfD) attacked Thunberg in harsh ways, according to a researcher.

Arron Banks’ comment on Twitter, joking about a “freak yachting accident” in August, upset many British politicians, celebrities, and academics. Tanja Bueltmann, founder of EU Citizens’ Champion, said Banks had “invoked the drowning of a child” for his own amusement and said most attackers of Thunberg are “white middle-aged men from the right of the political spectrum.” Gaby Hinsliff wrote in The Guardian that Thunberg has become “the new front in the Brexit culture war,” saying attacks on her give critics unwanted attention.

In September 2019, Nick Gillespie wrote in Reason that Thunberg’s emotional responses may be heartfelt, but they and the harsh replies they cause are not helpful for creating good environmental policies. In August 2021, Yasmeen Serhan wrote in The Atlantic that Thunberg has been targeted by far-right and populist groups with false information, including claims that she is a spoiled child, a leftist pawn, or even a Nazi.

The BBC summarized Thunberg’s influence: “She is credited with raising public awareness of climate change worldwide, especially among young people. Many call this ‘the Greta effect.’”

In response to her strong views, some politicians have acknowledged the need to focus on climate change. Britain’s environment secretary, Michael Gove, said, “When I listened to you, I felt great admiration, but also responsibility.”

In popular culture and art

Greta Thunberg has been shown in books, art, and other media. A book titled Greta and the Giants, written by Zoë Tucker and Zoe Persico and published by Frances Lincoln Children's Books, was inspired by her life. In San Francisco, an 18-meter mural of Thunberg was created by Argentinian artist Andrés Iglesias and displayed above Mason Street near Union Square. American painter Elizabeth Peyton used her 2019 portrait of Thunberg as the main image in one of her art shows. Thunberg has also been shown in several murals. In Bristol, a 15-meter-high mural by artist Jody Thomas shows the bottom half of her face as if underwater, a representation that began in May 2019. In May 2019, Thunberg appeared on the cover of Time magazine, where she was called a role model and one of the "Next Generation Leaders." She was also featured on the cover of British Vogue in September 2019, alongside fifteen others, as part of a special issue created by guest editor Meghan, Duchess of Sussex.

Some of Thunberg's speeches have been used in music. In 2019, she provided a voiceover for a song titled "The 1975" by the English band of the same name. She ended the song by saying, "So, everyone out there, it is now time for civil disobedience. It is time to rebel." The money from the song was given to Extinction Rebellion, as requested by Thunberg. In September 2019, John Meredith turned her speech at the UN Action Summit into a death metal song. Australian musician Megan Washington and composer Robert Davidson used the same "how dare you" speech in a performance about the future of music. DJ Fatboy Slim mixed this speech with his song "Right Here, Right Now" to create a mashup.

In 2019, Thunberg worked with the climate charity Project Pressure to create an art piece shown on the United Nations Secretariat Building in New York before the UN Climate Action Summit. The piece included the voices of six young activists, including Thunberg. It was visualized by Joseph Michael, written by Klaus Thymann, and accompanied by music from Brian Eno. The piece focused on the climate crisis and the urgent actions needed to reduce its effects.

In May 2020, Thunberg appeared in the music video "Retrograde" by Pearl Jam. She was shown as a fortune teller, with images in her crystal ball showing the effects of climate change in different countries.

On September 3, 2020, the Hulu documentary I Am Greta premiered at the Venice Film Festival. The film was directed by Nathan Grossman, who also handled the camera and sound equipment. It followed Thunberg's climate activism, starting with her school strike in August 2018 and ending with her two-week journey across the Atlantic to attend the UN Climate Summit in September 2019. After its premiere in Venice, the film was shown at the Toronto International Film Festival on September 11, 2020, and later released in theaters in Europe, North America, and Australia in October.

In March 2021, the University of Winchester placed a life-sized sculpture of Thunberg on its campus. BBC Studios produced a three-part series titled Greta Thunberg: A Year to Change the World. Some planned visits to different countries were not included because of the COVID-19 pandemic.

Honours and awards

Greta Thunberg has received many awards and recognitions for her work in climate activism. In May 2018, before she began her school strike, she won a climate change essay competition for young people organized by Svenska Dagbladet (The Swedish Daily News).
