People
The people around the movement — allies, family, scientists, leaders, and critics, described as the record shows them.
Malena Ernman
Opera singer and Thunberg’s mother; represented Sweden at the 2009 Eurovision Song Contest. She co-wrote the family memoir Scenes from the Heart (2018) with Svante Thunberg and has spoken publicly about the family’s lifestyle changes and her daughters’ diagnoses.
Svante Thunberg
Actor and Thunberg’s father. He co-wrote Scenes from the Heart (2018) and has accompanied her on several of her international trips, including the Atlantic crossing. He has spoken publicly in her defense against claims she is being manipulated.
Beata Ernman Thunberg
Thunberg’s younger sister. She has appeared publicly as a singer. She keeps a lower profile than her sister; this site records only that fact.
Luisa Neubauer
German climate activist, one of the most prominent organizers of Fridays for Future in Germany. She has appeared alongside Thunberg at demonstrations and summits, including Berlin in 2019.
Vanessa Nakate
Ugandan climate activist who has spoken and demonstrated alongside Thunberg at international summits. She has described being cropped out of an Associated Press photo of the two of them with other activists at Davos 2020 — an incident the AP apologized for and which became a widely discussed moment about representation in climate coverage.
Alexandria Villaseñor
American climate activist who founded the US Youth Climate Strike and the group Earth Uprising; she has demonstrated alongside Thunberg and spoken at shared events in the United States.
Jamie Margolin
American climate activist and co-founder of the Zero Hour youth climate movement; a contemporary of Thunberg in the youth-climate wave of 2018–2019.
Jean-Pascal van Ypersele
Belgian climatologist, former vice-chair of the IPCC, photographed with Thunberg at COP24 in Katowice. He represents the scientific establishment whose findings she cites — she has consistently framed her message as “listen to the scientists,” with van Ypersele among the IPCC figures whose work underpins that appeal.
António Guterres
UN Secretary-General, in office for the COP24–COP26 period. He praised youth climate activists including Thunberg while convening the summits she addressed — and was in turn criticized by her for insufficient action.
Pope Francis
Met Thunberg at the Vatican in April 2019, thanking her for her activism and encouraging her to continue. The meeting was reported by the Vatican and international media.
Boris Herrmann
German professional sailor who skippered the racing yacht Malizia II on its August 2019 Atlantic crossing carrying Thunberg (with co-skipper Pierre Casiraghi and Thunberg’s father). The voyage was organized to avoid the emissions of flying.
Donald Trump
US President (2017–2021; 2025–). A prominent critic: in December 2019 he posted that Thunberg “must work on her Anger Management problem”; she replied by changing her social-media bio to match his words (see Sayings). His dismissals of her and of climate activism are documented on Criticism and Response.
