Scientists Warn of Compounding Risks from ‘Godzilla-Level’ El Niño and Climate Change

As a powerful El Niño event intensifies, causing extreme weather conditions worldwide, Guardian environment journalists Jonathan Watts and Gabrielle Canon addressed public inquiries regarding the intersection of this phenomenon with the climate crisis.

Responding to questions about how climate breakdown is influencing the current El Niño and whether future events may become more severe, Watts highlighted that scientists have not yet reached a definitive consensus. He referenced Prof Mat Collins of the University of Exeter, a key author of major climate reports, who explained that climate change and El Niño function as separate forces that叠加 upon one another. According to Collins, if global warming has already established drought conditions, an El Niño event will likely worsen them, though the precise mechanics of their interaction remain complex.

Canon, based in California, described El Niño as creating an underlying signal that affects global weather systems rather than acting as a direct cause-and-effect driver. While forecasters possess significant knowledge of potential outcomes, she noted there remains uncertainty regarding exact unfolding events. In California, historical data shows a correlation between El Niño and heavier rainstorms in the southern part of the state, but predicting the timing or volume of these storms remains difficult.

Both journalists agreed that while El Niño increases risks, it offers no guarantees. Certain associations, however, appear stronger than others. Scientists are relatively confident that sea-level rise will impact coastlines throughout California. Additionally, El Niño is amplifying the Pacific hurricane season, which is already active, and contributing to higher global temperatures. As the current event strengthens and potentially breaks records, experts caution that significant uncertainty persists.
