Responding to the Climate Crisis through Trust and Innovation

The year 2025 served as a stark reminder of the escalating climate crisis, recorded as the third warmest year globally. For
the APEC Climate Center (APCC), however, it was a year of profound significance. As the Republic of Korea assumed the
APEC chair, APCC celebrated its 20th anniversary, leading international solidarity to address our shared climate chal-

cured Subseasonal to Seasonal (S2S) prediction technology—providing vital outlooks for the 14-to-60-day window and
effectively closing the gap between short-term weather and seasonal climate. Additionally, we have refined AI-driven
techniques for the early detection of extreme climate events, enhancing our proactive response capacity. 30 Research Projects in 2025
1. Operation and Technical Development of Real-Time, Highly Validated Climate Prediction
Finally, we have fortified national climate resilience through a robust legal and scientific framework. In alignment with
