Extreme weather is increasingly deadly and damaging, yet sophisticated climate models are failing to capture crucial signals, as highlighted in a Nature Communications study. Researchers from Columbia University found that the equatorial cold tongue in the tropical Pacific is not warming as expected, which affects climate patterns globally. This discrepancy leads to incorrect projections regarding regional climates, including droughts and increased tropical cyclones, emphasizing the need for re-evaluating existing climate models to better address these phenomena and predict future changes accurately.
The tropical Pacific Ocean, particularly the equatorial cold tongue, is exhibiting behaviors inconsistent with climate model predictions, impacting global weather patterns and predictions.
Our work is at the center of the debate in the climate science community, sparking a rethinking of models worldwide due to discrepancies in cold tongue warming.
