What are short term climate fluctuations caused by?

Short-term climate fluctuations are primarily caused by natural phenomena such as El Niño and La Niña events, which can significantly alter weather patterns and temperatures over months to a few years. Other factors include volcanic eruptions, which can inject aerosols into the atmosphere, leading to temporary cooling, and variations in solar radiation. Additionally, changes in ocean currents and atmospheric circulation can also contribute to these short-term climate variations.
