El Niño Southern Oscillation (ENSO) is a cyclical climatic phenomenon that impacts regions globally, bringing extreme rainfall, drought, and other conditions . The patterns of ENSO are currently misunderstood, and rely on long term records from natural proxies to further interpret its responses to different mean states of climate. Ecuador and Peru are highly vulnerable to the fluctuations in El Niño weather patterns, and thus, contain records of each differing El Niño that occurs. This makes the region a primary location for collecting natural proxy records of ENSO cycles. This study extracted 4 meters of lake core from Laguna Nariguina, a lake in the western Andes of Ecuador, which receives high amounts of sediment deposits during El Niño-induced precipitation events. Comparing the core to previous natural proxy records from the Ecuador and Peru area, we were able to determine ENSO fluctuations were moderate-large in the beginning of the Holocene, slowed down in the middle, and enhanced towards the end, as anthropogenic forces have shifted climate in the recent century. ENSO fluctuations have large impacts in many countries around the globe. Although the interaction of oceanic warming and oscillation changes are centralized above the southern Pacific Ocean, the effects of the phenomenon are felt as far as Indonesia, Sub-Saharan Africa, North America, and more, due to teleconnections that stretch much further than the Pacific. Throughout literature research, it has become clear that the differentiating El Niños that strike Ecuador, Peru, and other varying countries, cause detrimental impacts on agriculture, fishing, widespread health, political stability, and economic standing in each of the affected locations. Some of the most severe ENSO droughts that have hit Sub-Saharan Africa have furthered undernutrition, poverty, and the spread of viral epidemics. Similarly, coastal areas of Peru and Ecuador that house impoverished populations are struck the hardest by coastal El Niños, and receive the slowest governmental aid in reparations. The impacts of El Niño on affected regions reach multiple aspects of socioeconomic wellness and leave the country vulnerable to the changes occurring in today’s climate. As climate changes, ENSO responses will also change. In order to better prepare for these weather shifts, we need to further analyze historical El Niños to be able to predict how ENSO will react to the forced climatic changes of today, and the future.
