This is actually my final contribution to this series. I am grateful for the opportunity I have had to explore the scientific and social aspects of climate change in my own way. In this article, I will discuss how we should respond to the imminent reality of a 1.5°C global average temperature rise and the attitude we should adopt moving forward. Japan’s record-breaking heatwaves and global warming The summer of 2025 in Japan was astonishingly hot. The daily maximum temperature reached 41.8°C, far higher than ever before, and the number of people receiving medical attention for heatstroke increased sharply across the country.[1] Many people undoubtedly felt the seriousness of climate change firsthand. In ... [Read more]
