Greta Thunberg delivered the line during her speech at the United Nations Climate Action Summit in New York in September 2019, addressing world leaders about inaction on climate change. The address was broadcast and the phrase quickly became its quoted moment, shared in news clips, reaction videos and media edits. As the speech circulated, creators began isolating the outburst for satirical and critical edits, using it to accuse public figures, brands and hypocrites of failing to act. Its staying power comes from that confrontational tone, which works whenever someone wants to highlight broken promises or empty words.
