Short summary

The polar ocean narrative integrates physical, ecological, and societal indicators and shows amplified warming, sea ice loss, and compound change for coastal erosion in the Arctic. Indicators in the Antarctic illustrate an international governance challenge, where biodiversity protection requires both conservation and global mitigation. Together, these examples show that polar ocean change is not a collection of isolated environmental trends, but undergoes an interconnected transformation.
