An audience member used the phrase "climate catastrophe" during the Sunak-Starmer June 4 debate

The claim that an audience member used the phrase 'climate catastrophe' during the Sunak-Starmer June 4 debate appears to be accurate. Multiple sources, including The Guardian and Medium, reference discussions around climate change and the use of strong language to describe the situation. However, it is important to note that the term 'climate catastrophe' is often used in public discourse to emphasize the urgency of climate issues, and its use in the debate context does not necessarily imply misinformation. The term reflects a growing concern among scientists and policymakers about the severe impacts of climate change if significant action is not taken. For further context, the debate included various topics, and climate change was a significant point of discussion, reflecting its importance in current political and public discourse.
