Climate variability refers to the natural fluctuations in climate patterns that occur over time and space. These variations can be caused by factors such as changes in ocean currents, solar radiation levels, and atmospheric circulation patterns. Climate variability is distinct from human-induced climate change, which refers to long-term shifts in global temperatures and weather patterns driven by human activities like burning fossil fuels and deforestation. While both concepts are related to changes in the Earth's climate system, they involve different causes and have different implications for our planet's future.
