Scientists Debate Whether Climate Change Is Intensifying El Niño Through 2027

Summary
Scientists are split on whether climate change is making El Niño stronger, even as a newly started event is expected to last through 2027 and could be especially potent.
Since the 1980s, El Niño episodes have been comparatively strong, and that run stands out against records stretching back 600 years, fueling arguments that global warming may be amplifying the pattern.
Other researchers say the evidence is still too unclear to prove that link, leaving the question unresolved until more observations accumulate over coming years.
The stakes are high because El Niño raises global temperatures and can intensify weather disruption worldwide, increasing drought risk in some regions and flooding in others.

As El Niño strengthens into 2027, what permanent changes to our weather will it leave behind?
The Unfolding 2026-27 El Niño: Scientific Projections, Global Impacts, and Urgent Policy Responses
Overview
The 2026-27 El Niño is currently in its early stages, having begun to develop between March and June as oceanic and atmospheric conditions start to shift. Over the coming months, it is expected to intensify, with its peak typically occurring between November and February. The strongest effects are anticipated in late 2026 and early 2027, but the most significant global temperature anomalies usually appear in the second year after development, meaning 2027 could see notable impacts. This progression highlights the importance of early preparedness to address the widespread risks associated with a strong El Niño event.
