I think they are pointing at an acceleration of the situation. Last summers have been relatively hot in West Europe as well, resulting in people buying airco’s [1]. Of course, people using airco's speeds up global warming (unless the electricity used is 100% renewable). But at the individual level, it is understandable that people do this during heatwaves. Use green energy ;). [1] residential buildings traditionally do not have airco’s in countries such as Germany or The Netherlands.
