Heat records shattered in central Europe heat wave
A heat wave brought record temperatures across Europe during late-June and early-July. On July 1, London experienced its hottest July maximum temperature on record: 98.1°F (36.7°C). Paris recorded its second hottest day ever on July 2, with a high temperature of 103.5°F (39.7°C), and Berlin experienced its highest temperature on record, 100.2°F (37.9°C), on July 4.
On July 5, Germany set a new all-time, nation-wide hot temperature record, reaching 104.4°F (40.2°C) in the town of Kitzingen.
Climate change identified as a "major factor"
Model experiments positively identified human-caused climate change as a "major factor in setting the conditions for the development of the 2015 heat wave."
A 2016 attribution study by Sippel et al. confirms that human-induced climate change has contributed to the increase in the frequency and intensity of short-term heat waves and heat stress, such as the summer 2015 event in central Europe.
The 2015 summer extreme hot temperature occurred in the context of a decade of summer warming and increases in hot temperature extremes.
