2023 heat waves

With a deviation of over 0.7 °C from the average of the years 1991 to 2020, July 2023 marks the warmest July ever recorded. Numerous regions in the Northern Hemisphere, particularly in southern Europe, went through severe heatwaves, with anomalies of +4 °C in Italy, Greece, and Spain. Additionally, North Africa and the Canadian Arctic saw notably high temperatures, reaching peak anomalies of +5 °C and +7 °C, respectively. More detailed information can be found in the C3S Climate Bulletin.

A number of heat waves began across parts of the northern hemisphere in April 2023, many of which are ongoing. Various heat records have been broken,[1] with July being the hottest month ever recorded.[2]

Scientists have attributed the heat waves to man-made climate change.[1][2] Another cause is the El Niño phenomena which began to develop in 2023.[3] However, recent findings show that climate change is exacerbating the strength of El Niño.[4]

The heatwaves caused severe damage in areas such as the western United States, southern Europe, and parts of Asia.[5] The abnormal temperatures have led to a "very extreme" likelihood of wildfires, according to the Fire Weather Index.[6]

The heatwaves were also occurring alongside some unusually heavy flooding.[7][8]

In response to the heatwave some leaders called for greater action to stop climate change.[9] President of the United States Joe Biden has taken some measures to protect the population from extreme heat.[10][11]
