Global warming is disrupting a 400-year-old climate link between the Indian and Pacific oceans

A new study combining paleoclimate evidence and climate model simulations indicates that human-caused global warming is breaking a long-standing climatic connection between the tropical Indian and Pacific oceans. While volcanic eruptions have temporarily disrupted this link in the past, the current breakdown appears to be driven by greenhouse gas emissions, representing a highly unusual shift in the relationship between these two major ocean basins.
