On the ground across Japan. From Hiroshima’s haunting legacy to Kyoto’s historic climate commitment.
In Hiroshima, the site of unimaginable devastation from the atomic bomb in 1945, scientists now warn of a quieter, more insidious threat. Our oceans are absorbing five times the energy of a Hiroshima bomb every second. The result? Unprecedented storms, extreme weather, and a planet in flux. The scale is terrifying. The science is clear. Will we act?
Travel further south and Nik finds Pacific coastline of Japan is already under siege. Warming waters fuel catastrophic weather. Floods, landslides, and growing fears of tsunamis. Local leaders are calling for a shift in mindset from their own communities, with a mixed response. The message is urgent: the climate emergency is no longer distant, it’s here.
The former imperial city of Kyoto is where global leaders signed the COP3 Protocol to combat climate change in 1997. Nik revisits where the big breakthrough happened. But he asks whether the core principles really will endure. Their promise echoes in an increasingly fragile world. Standing in the very hall where commitments were made, the questions now feel louder than ever: Are we living up to them? Will they endure? Nik expresses concern.
