Which phenomenon is associated with global climate impacts due to ocean temperature anomalies?

El Niño is a significant climatic phenomenon that arises from variations in ocean temperatures across the central and eastern Pacific Ocean. These temperature anomalies can manifest every few years and have widespread effects on global weather patterns, leading to changes in rainfall, droughts, and storm intensity in various regions around the world.

During an El Niño event, warmer ocean temperatures contribute to shifts in atmospheric circulation. This can result in increased precipitation in some areas, such as the southern United States and parts of South America, while simultaneously causing droughts in regions like Australia and southeast Asia. The impacts on agriculture, water supply, and even the risk of natural disasters like floods and wildfires can be profound, illustrating how interconnected ocean temperatures and climate are.

In contrast, other options such as climate cycles, ozone depletion, and carbon sequestration refer to different concepts. Climate cycles generally describe longer-term changes in climate that can result from numerous factors, including ocean currents, but do not specifically target short-term temperature anomalies like El Niño. Ozone depletion primarily concerns the deterioration of the ozone layer, which affects ultraviolet radiation levels, and is not directly related to ocean temperatures or general climate anomalies. Carbon sequestration deals with the storage of carbon to reduce carbon dioxide levels in the atmosphere and is a strategy for
