Climate cycles refer to long-term patterns of temperature and weather changes on Earth. These cycles can last for decades, centuries, or even longer, and are influenced by various factors, including solar radiation, ocean currents, and volcanic activity. They can lead to periods of warming or cooling, affecting ecosystems and human activities. One well-known climate cycle is the El Niño-Southern Oscillation (ENSO), which occurs every few years and can significantly impact global weather patterns. During an El Niño event, warmer ocean temperatures in the Pacific Ocean can lead to increased rainfall in some regions and droughts in others, demonstrating how interconnected our climate systems are.
