Which example best illustrates climate rather than weather?

• A. The average temperature of the region over the last 30 years.
• B. A storm day in January.
• C. A thunderstorm this afternoon.
• D. A heatwave last week.

Answer: (A)

When we talk about climate, we’re focusing on long-term patterns rather than single-day events. Weather is the day-to-day state of the atmosphere, like storms and heat on a specific day, while climate is the typical conditions you’d expect over many years.

The average temperature of the region over the last 30 years shows the region’s usual temperature range and overall climate, because it averages out short-term fluctuations and reveals the normal pattern you’d expect across seasons and years. The other examples describe specific weather events that happened in a short time frame—stormy day, a thunderstorm, or a recent heatwave—rather than the long-term pattern.
