The Kuroshio, or "Black Current," is one of the largest streams of water anywhere in the world, and its recent movement has triggered record-warm ocean temperatures and upended fisheries, an indelible staple of Japanese culture.
Scientists say the warm waters have even amplified heatwaves on land and driven extreme rainfall.
And while there are signs some of the changes are now waning, fishing communities say they aren't yet back to normal.
Meanwhile, scientists worry it could be a sign of more volatility to come.
The position of the current could keep fluctuating, said Bo Qiu, a leading Kuroshio expert at the University of Hawaiʻi at Mānoa. "It's hard to predict the future, but given the data we have so far, I can only see the intensity becoming larger and larger," he said.

Sustainable construction is becoming a test of bankability, with asset owners backing projects that improve whole life carbon performance and meet a credible life cycle cost threshold. Aldi’s plan to install solar panels on half its UK stores by the end of 2026 shows that decarbonising the built environment is being driven by portfolio retrofit, energy-efficient buildings and low carbon design rather than headline-led new build. Sustainable building design, sustainable design and eco-design for buildings are being judged with far greater rigour through whole life carbon assessment, lifecycle assessment and building lifecycle performance, with stronger focus on embodied carbon, embodied carbon in materials and the carbon footprint of construction as the market pursues net zero carbon buildings and net zero whole life carbon.
EV charging is strengthening the business case for green infrastructure, with viable sites attracting sharply higher rents and turning car parks, grey land and brownfield plots into infrastructure for sustainable urban development. The planned wind-down of SDCL Efficiency shows that environmental sustainability in construction still has to satisfy conventional capital markets. Green construction, eco-friendly construction, low carbon building and carbon neutral construction are now expected to deliver measurable returns, not only sustainability claims.
Standards on site are tightening. The Considerate Constructors’ Scheme has revised its checklist and scoring model, raising expectations for sustainable building practices, resource efficiency in construction and low-impact construction. Recycleye’s latest AI sorting system supports the circular economy and circular economy in construction by improving recovery of green building materials, low carbon construction materials, low embodied carbon materials and renewable building materials. This strengthens life cycle thinking in construction, sustainable material specification, end-of-life reuse in construction and circular construction strategies, with growing value placed on environmental product declarations (EPDs), green building products and evidence frameworks associated with BREEAM and BREEAM v7.
