Measures based on past examples no longer suffice. Climate change-induced disasters are already more frequent and severe than had been envisaged, exceeding the thresholds that can be tolerated by human society. How should we prepare to face this reality? The Climate Change Adaptation Act, aimed at promoting adaptation measures, stipulates that national and local governments, businesses, and citizens should work together to implement such measures. Another reason why we must take effective adaptation measures without delay is to ensure that the next generation can enjoy comfortable lives. Initiatives grounded in scientific knowledge are being implemented across Japan.
