The high temperature event in July 2018 caused record-breaking human damage throughout Japan. Large-ensemble historical simulations with a high-resolution atmospheric general circulation model showed that the occurrence rate of this event under the condition of external forcings in July 2018 was approximately 20%. This high probability was a result of the high-pressure systems both in the upper and lower troposphere in July 2018. The event attribution approach based on the large-ensemble simulations with and without human-induced climate change indicated the following: (1) The event would never have happened without anthropogenic global warming. (2) The strength of the two-tiered high-pressure systems was also at an extreme level and at least doubled the level of event probability, which was independent of global warming. Moreover, a set of the large-ensemble dynamically downscaled outputs revealed that the mean annual occurrence of extremely hot days in Japan will be expected to increase by 1.8 times under a global warming level of 2°C above pre-industrial levels.

The July 2018 High Temperature Event in Japan Could Not Have Happened without Human-Induced Global Warming https://t.co/RUc3jS5Vlz

@E_repens 例えば2018年の日本の猛暑が温暖化の影響だという研究が出てたり、温暖化もはや将来の話ではなく、地域によってはすでに影響・被害が強く出てる。生物多様性の緊急性は認めるけど温暖化が緊急性がないというのは、残念ながら認識がまちがってると思うよ…。 https://t.co/19Mb86cIeP
The 2018 heatwave in Japan killed more than 1000 people and "would never have happened without human-induced climate change" according to a research study published last year. That it's already happening again is horrific. We are in a climate emergency. https://t.co/DwOr6NUjsT https://t.co/i1I4TmhR6V

Fascinating paper here. Slate has a good summary in plain language. The paper is here: https://t.co/ugOzClv6ou https://t.co/7dwjiXpti2
