Extreme Heat Days Are About 4 Times More Frequent Than 90 Years Ago

The Japan Meteorological Agency defines an "extreme heat day" as a day when the maximum temperature reaches 35 degrees Celsius or higher. The annual number of extreme heat days at 13 locations nationwide is increasing, and the average annual number over the last 30 years (1996-2025) has increased by about 4.2 times compared to the first 30 years of the statistical period (1910-1939), with an average of about 3.2 days. Why does extreme heat occur? "Survival in Extreme Heat" delves into the mysteries and threats of such abnormal weather.

Mass Fish Deaths, Coral Bleaching - Extreme Heat Changes the Earth

One day, as extreme heat continues and an alert is issued, Geo and Kei are asked by Dr. No to go to an aquarium near the sea. "Maybe it'll be a little cooler," Geo and the others hoped, but it was just as muggy as in the city!

Extreme heat also has various impacts on the ecosystems of the Earth where we live. At the fish farm Geo and his friends visited, fish died in large numbers, and bleached coral reefs spread in the sea.

Furthermore, in a village near the coast, villagers collapse from heatstroke... In this life-threatening crisis, how will Geo and Kei confront this extreme heat!?
