September 2024 floods in Japan exacerbated by human-driven climate change & natural variability

Meteorological conditions similar to that causing floods in Japan are up to 5 mm/day (up to 30%) wetter over the prefecture of Ishikawa (Japan)  in the present than they have been in the past.  Temperatures are up to 1.5 ºC warmer in the present compared to the past . 

This event was associated with very rare meteorological conditions 

We mostly ascribe the increase in precipitation of Japan floods to human driven climate change and natural climate variability likely played a modest role.
