According to data from the European Union's Copernicus Climate Change Service, June to August 2022 was the hottest summer on record globally. Several countries experienced extreme and prolonged heatwaves over the summer, including parts of the US, Europe, Japan, Australia, and other regions of the southern hemisphere. Many locations saw their hottest summer days on record. Scientists warn that global warming driven by humanity's emissions has elevated summer heat to dangerous, record-breaking levels. If emissions are not urgently reduced, future summers will be even hotter and more extreme than what was observed in 2022.
