A study says the climate phenomenon known as El Nino and not climate change was a key driver in low rainfall that disrupted shipping at the Panama Canal last year. El Nino refers to the natural warming of the central Pacific that changes weather worldwide.

The climate phenomenon known as El Niño — and not climate change — was a key factor driving low rainfall that disrupted shipping at the Panama Canal, scientists said Wednesday, May 1, 2024.

Human-caused climate change was not a primary driver of the Central American country’s unusually dry monsoon season, the World Weather Attribution group concluded, after comparing the rainfall levels to climate models for a simulated world without current warming. “Natural variability plays a critical role in driving many extremes,” said Kim Cobb, a climate scientist at Brown University, who was not involved in the study. “This is an important reminder that climate change isn’t always the answer.”Mexico’s presidential candidates discuss social spending, climate change in 2nd debatePanama experienced one of its driest years on record last year, receiving below-average rainfall for seven of the eight months of its May to December rainy season.

Meanwhile, the analysis showed that El Nino reduced the 2023 rainfall by about 8%, and that it’s unlikely Panama would have experienced such a dry rainy season without the influence of the weather phenomenon. The researchers said increased demand for water in the region worsened the shortfall.
