Google Gemini made this image but I am the one who told it what to make! 40° Celsius. What does this mean? In America, it means: go to Google and find out what this is in Fahrenheit (104°). In Europe, it means death! And death has come to Europe. The sun giveth life; the sun taketh away. Every summer, this happens. A heatwave hits Europe and then people start melting into the cobblestone streets.
