Why are El Niños getting stronger? 1,000-year-coral record points to climate change

Phys.orgIndependentCenter9 hr. ago

A study analyzing coral records from the Galápagos Islands reveals that El Niño events have become significantly stronger in the past 40 years compared to the last 1,000 years. Researchers observed that rising global temperatures, driven by human activity, correlate with increased El Niño intensity, leading to more severe weather impacts. Historical data indicates that major El Niño events like those in 1982–83 and 1997–98 may signal future extremes. The 1982 El Niño caused a marine heatwave that devastated marine ecosystems, killing over 95% of Galápagos corals and disrupting fisheries. Scientists warn that ongoing climate change could make future El Niño events even more destructive, with potential global implications.

A new study led by palaeoclimatologist Julia Cole suggests that strong El Niño events are becoming more frequent due to human-caused climate change. Using a 1,000-year coral record from the Galapagos Islands, the research indicates that the past century has seen more frequent strong El Niño events compared to the previous 1,000 years. The findings, published in Science, show that rising global temperatures linked to greenhouse gas emissions may be intensifying these climatic patterns. While climate models predict continued increases in El Niño frequency, uncertainties remain regarding the exact impacts on future Pacific temperature cycles. The study highlights the importance of understanding these changes for better preparation against potential ecological and economic consequences.
