Man-made climate change made the extremely high temperatures around the Mediterranean in July possible. Without it, the heatwave would have been up to 3.3 degrees Celsius cooler. These are the key findings of a new rapid analysis by the World Weather Attribution (WWA) research group. „Once impossible, these heatwaves are now relatively common due to human-caused warming and are expected to occur about once a decade. With further warming, they will become even more frequent,“ WWA said in a statement.
