El Niño event intensifies before peak in November or December

A record-breaking El Niño event is currently unfolding, with forecasts indicating it will continue to intensify before peaking in November or December.

The effects of this monster storm will be felt for a long time after its peak next year, as the climate system takes months to recover from such extreme events.

According to hurricane specialist Jeff Masters, this super El Niño event could drive multiple climate regime shifts, similar to those seen following past super El Niños.

Masters warns that one of the devastating consequences will be a severe drought in the Amazon rainforest, potentially killing off some areas of remaining forest.

As the massive El Niño event continues to unfold, its effects on global temperatures are becoming increasingly evident. The phenomenon is causing a sudden surge in surface temperatures worldwide, with some areas experiencing rises of 7°C or more above normal levels.

This dramatic temperature spike has already surpassed the critical 5°C threshold that climate experts had hoped to avoid. The implications of such extreme warming are far-reaching and potentially catastrophic, as scientists have warned of devastating consequences for ecosystems around the world.

Meanwhile, beneath the surface of the Pacific Ocean, a complex interplay of oceanic processes is also underway. Warm water in the eastern Pacific triggers massive underwater waves known as Rossby waves that travel westwards towards the continental shelf in the western Pacific. These waves then bounce back eastwards in the form of cold Kelvin waves.

These interactions are crucial to understanding the end of El Niño events, and scientists have identified multiple processes involved in their onset, maturation, and demise.

Scientists are still trying to predict how this massive El Niño event will come to an end. According to Michael McPhaden, a researcher who has been studying these events, there is currently no clear indication of when or how it will dissipate.

The 1997 El Niño ended with a dramatic drop in sea-surface temperatures in the eastern equatorial Pacific, plummeting by as much as 8°C in just one month. This was followed by a strong and long-lasting La Niña event. In contrast, the next major El Niño event in 2015 faded gradually and was succeeded by a weak and short-lived La Niña.

The current El Niño's demise is proving difficult to predict, with McPhaden stating that it is unclear how this event will wind down. However, what is certain is that its effects will persist even after it has ended.

The ongoing El Niño event has sparked concerns about its long-term effects on global climate patterns. Researchers have warned that this super-strong weather phenomenon could lead to permanent changes in certain regions. According to Jong-Seong Kug and his team at Seoul National University in South Korea, the combination of extreme El Niños and global warming can cause irreversible shifts in climate regimes.

The 2015 super El Niño had a lasting impact on sea-surface temperatures in the Gulf of Mexico, which have continued to rise since then. While other factors contributed to this increase, Kug acknowledges that the El Niño played a significant role. The current even-stronger El Niño event is likely to trigger similar shifts in climate patterns.

As Kug notes, "We are experiencing a very strong El Niño event." Masters agrees that these sudden changes will be costly and disruptive for human civilization, which has adapted to 20th-century climate conditions. This raises the possibility that some parts of the world may never return to their pre-El Niño state.
