Indian and Pacific Ocean climate decoupling
Overview
Research published in Nature Communications indicates an unprecedented breakdown in the climate coupling between the Indian and Pacific Oceans. Historically, these basins were largely coupled, though a period of decoupling occurred between 1810 and 1850 due to major tropical volcanic eruptions.
Recent data suggests that modern anthropogenic greenhouse gas emissions are now driving a distinct shift in inter-basin variability. Since the 1950s, the tropical Indian Ocean has warmed by approximately 0.1 degrees Celsius per decade, while the Pacific Walker circulation has strengthened since the 1980s. This divergence has decoupled the two systems, making it increasingly difficult for scientists to use Pacific patterns to predict Indian Ocean climate trends.
