Climate change refers to long-term changes in the average temperature and weather patterns of a region or the planet as a whole, typically caused by human activities such as burning fossil fuels and deforestation. Climate change is often associated with global warming and the increase in greenhouse gas emissions.
On the other hand, climate variability refers to short-term fluctuations in weather patterns and temperature that occur naturally over time. These variations can be caused by factors such as volcanic eruptions, solar radiation, ocean currents, and natural climate cycles like El Niño and La Niña.
In summary, climate change refers to long-term shifts in climate patterns due to human activities, while climate variability refers to short-term fluctuations in weather patterns that occur naturally.

Climate Change
- Definition: Long-term shifts in average weather patterns and other climate variables (e.g., temperature, precipitation) over an extended period (typically decades or longer).
- Causes: Primarily human-induced factors like the emission of greenhouse gases (e.g., carbon dioxide, methane) that trap heat in the atmosphere, leading to global warming.
- Characteristics: Gradual and persistent changes in the average state of the climate system.
- Impacts: Wide-ranging and often irreversible, including rising sea levels, more frequent and intense extreme weather events, changes in ecosystems, and impacts on human health.
Climate Variability
- Definition: Short-term fluctuations in weather patterns or other climate variables over periods of days to years.
- Causes: Natural climate processes, such as the El Niño-Southern Oscillation (ENSO) or the North Atlantic Oscillation (NAO), as well as human activities (e.g., land use changes).
- Characteristics: Relatively short-lived and often recurring changes around the average climate state.
- Impacts: Can have significant but temporary impacts on agriculture, water resources, and other sectors, but generally do not alter the long-term climate state.
Key Differences:
- Time Scale: Climate change occurs over decades or longer, while climate variability operates on shorter time scales.
- Causes: Climate change is primarily caused by human activities, while climate variability is largely due to natural factors.
- Impacts: Climate change leads to substantial and长期 impacts that can disrupt ecosystems and alter human societies, while climate variability typically causes more temporary disturbances.
