A recent heatwave in Europe has led to the spread of misinformation about climate science, with claims that historic heatwaves prove current temperatures are normal. Climate scientists, including Sonia Seneviratne and Zeke Hausfather, report experiencing harassment and hostility online due to their work. They emphasize that misinformation is a significant issue in climate discussions, with false narratives about heatwaves and temperature records being circulated. Experts argue that while extreme heat events are becoming more frequent due to human-induced climate change, claims about the reliability of temperature records are unfounded.
