For centuries, the Indian and Pacific oceans have behaved as a connected climate system. New research described by ScienceDaily shows that this long-standing relationship is now breaking down in an exceptional way.
The finding is based on ancient climate records, which suggest that volcanic eruptions disrupted the oceanic link in the past. Those disruptions were temporary, however. The current breakdown appears to be driven by human-caused global warming, marking a departure from the natural pattern seen over the past 400 years.
Scientists are still working to understand the full consequences, but the weakening link could alter weather and climate patterns across a large part of the globe. The report highlights how quickly human influence is now overriding natural climate relationships that have persisted for centuries.
