The wider picture

El Niño is a disruption in the usual pattern of water and air movement in the Pacific Ocean, occurring roughly every two to seven years. This phenomenon has historically affected fishermen off the western coast of South America, causing mass death in the food chain they relied on. The current situation is alarming, as a strong El Niño is anticipated to emerge, with an 80 percent chance of occurrence.

Recent developments indicate that the El Niño event of 2023/24 could contribute to 2024 being Earth’s warmest year on record. Experts are increasingly concerned about the implications of this climatic shift. Daniel Swain, a climate scientist, stated, “Whew. All signs are increasingly pointing to a significant, if not strong to very strong, El Niño event.” This sentiment is echoed by other meteorologists who warn of the potential for drastic weather changes.

Ben Noll, another expert in the field, cautioned that “changes in location, intensity and frequency of droughts, floods, heat waves and hurricanes are all likely.” The ramifications of these changes could be severe, affecting agriculture, water supply, and overall human health. The World Meteorological Organization (WMO) has also raised alarms about the rapid and large-scale changes to the global climate, warning that the damaging effects could last for centuries.

In addition to the immediate impacts of El Niño, the past eleven years have been the warmest since records began in 1850. This trend is compounded by the fact that atmospheric concentrations of CO₂ are now at their highest level in at least two million years, primarily due to human activities. The combination of these factors makes the current climate situation particularly precarious.

As we look ahead, the potential for a ‘super’ version of El Niño, which occurs roughly once every 10-15 years, looms large. There is a 22 percent chance of this more intense phenomenon developing by August. Such an event could exacerbate the already concerning trends in global temperatures, which in 2025 were approximately 1.43°C above pre-industrial levels.

Experts like Eric Webb have pointed out that due to the increasing concentration of greenhouse gases, the climate system cannot effectively exhaust the heat released in a major El Niño event before the next one arrives, pushing the baseline temperature upward again. Dr. John Kennedy warned, “If we transition to El Niño, we will see an increase in global temperature again – and potentially to new records.” This underscores the urgency of monitoring and preparing for the upcoming changes.

As the world braces for the impacts of El Niño, officials and observers are closely watching the situation. The potential for record-breaking temperatures and extreme weather events raises significant concerns for global stability. The time to act is now, as the consequences of inaction could be dire.
