There is evidence that the Earth's climate has fluctuated over time, with some regions experiencing colder or warmer climates than they currently do. For example, during the last ice age, much of North America and Europe were covered in glaciers, indicating a much colder climate than today. Similarly, regions such as the Sahara Desert were once lush and tropical, indicating a much warmer climate in the past. Therefore, option A is the best choice as it reflects these changes in climate over time.
