Explanation:

To determine the cause of sudden climate changes, we analyze each option:

• El Niño: Causes gradual climate shifts over seasons/years.
• Solar radiation: Changes slowly over long periods.
• Thermohaline circulation: Changes occur over centuries/millennia.
• Volcanism: Large volcanic eruptions release aerosols, ash, and gases, blocking sunlight and causing rapid (sudden) climate changes (e.g., cooling) in a short time (months to years).
