Is 'El Niño' just a natural phenomenon? "Climate change has increased the frequency and intensity of El Niño" 지구 온난화로 인해 '엘니뇨' 현상이 더 빈번하고 강하게 발생하고 있다는 연구 결과가 나왔다. A study has found that global warming is causing El Niño to occur more frequently and with greater intensity. 27일 국제 학술지 '네이처'는 기후변화와 엘니뇨의 상관관계에 대해 분석한 국제 연구진의 논문을 공개했다. On the 27th, the international academic journal 'Nature' published a paper by an international team of researchers analyzing the correlation between climate change and El Niño. 엘니뇨는 중·남미에 폭우와 가뭄을 일으키는 대표적인 기후 현상이다. El Niño is a representative climate phenomenon that causes heavy rain and drought in Central and South America. 연구진은 1900년부터 2017년까지 117년간의 데이터를 분석했다. The team analyzed data from 117 years, from 1900 to 2017. 분석 결과 기후변화로 인해 엘니뇨의 빈도는 20%, 강도는 10% 증가한 것으로 나타났다. The analysis found that the frequency of El Niño increased by 20% and its intensity by 10% due to climate change. 특히 1980년 이후로 엘니뇨 현상이 더 빈번하게 발생하고 있었으며, 최근 40년간 발생한 엘니뇨 10개 중 8개는 기후변화의 영향으로 발생했다는 분석이다. In particular, El Niño phenomena have been occurring more frequently since 1980, and it is analyzed that 8 out of 10 El Niño events that occurred in the last 40 years were caused by the impact of climate change. 연구진은 "엘니뇨는 자연 재해가 아닌 인간의 활동으로 인한 기후변화의 영향"이라며 "엘니뇨로 인한 피해를 줄이기 위해 기후변화 완화를 위한 적극적인 노력이 필요하다"고 강조했다. The researchers emphasized, "El Niño is not a natural disaster, but the impact of climate change caused by human activities. In order to reduce the damage caused by El Niño, active efforts to mitigate climate change are needed."

As the current "El Niño" is rapidly escalating into an unprecedented "super" El Niño, studies have revealed that climate change is exacerbating this natural phenomenon. The increase in Earth's temperature due to human activities, specifically greenhouse gas emissions from industrialization, is pushing the planet's climate system beyond its normal limits.

Researchers from the University of Michigan, led by Dr. Julia Cole, analyzed Pacific Ocean sea temperatures over the past 1,000 years and found that the variability of "El Niño Southern Oscillation" (ENSO) has been amplified by anthropogenic climate change. ENSO is a large-scale weather pattern occurring in the equatorial Pacific Ocean, where ocean and atmospheric interactions lead to variations in sea surface temperatures, resulting in extreme weather events such as droughts and floods.

Though ENSO has existed for at least thousands of years, some scientists argue that the rise in Earth's temperature due to human-induced climate change is intensifying it further. ENSO variability, which appeared to be relatively low and consistent for most of the past 1,000 years, significantly increased during the 20th century, and especially in the present "modern" era, showing a 36.5% increase compared to pre-industrial times and a 16.2% increase compared to the 20th century.

This heightened variability suggests that El Niño events are becoming more frequent and intense due to human-caused climate change. The researchers warn that the extreme weather conditions caused by these intensified El Niño events could lead to massive economic losses, ecosystem destruction, and human suffering worldwide. While the current study does not directly connect El Niño variability to greenhouse gas emissions, the strong correlation between observed El Niño intensification and climate model simulations driven by rising greenhouse gas concentrations strongly suggests that climate change is playing a significant role in this phenomenon.

Given the high probability of even more powerful El Niño events in the future, it is crucial to pay close attention to their potential impacts on temperature, precipitation, and extreme weather patterns in the Korean Peninsula.
