Story summary

Rising ocean temperatures near Japan, especially around Hokkaido, have caused a staggering two-thirds drop in konbu (kelp) harvests over the past 30 years. The Japan Meteorological Agency warns that diminishing sea ice in the Sea of Okhotsk is disrupting marine ecosystems and threatening vital seafood resources like scallops, as global warming reshapes marine life distribution.

The Kyoto Protocol, established in 1997, aimed to combat climate change by mandating a 6% reduction in greenhouse gas emissions from 1990 levels. Despite these efforts, rising ocean temperatures have caused a two-thirds decline in konbu harvests near Hokkaido over the past 30 years, highlighting the ongoing environmental crisis and the urgent need for effective climate action to protect marine ecosystems.
