Swedish climate activist who began a solitary school strike outside the Swedish parliament in 2018, aged 15, which grew into the global Fridays for Future movement. She is autistic and has spoken publicly about it as part of how she sees the climate crisis clearly.
She turned a single, quiet protest into a worldwide movement of young people demanding action on climate change, and has never softened her message to make adults more comfortable. Her bluntness became the point.
Her collected speeches, published as 'No One Is Too Small to Make a Difference', are a direct primary source.
