7. During the Eocene period (roughly 56 to 34 million years ago), the amount of carbon dioxide in Earth's atmosphere was double or possibly even five times as large as it currently is. Fossils from this period show that there were extensive forests near the north and south poles, and palm trees as far north as Alaska and Scandinavia. This suggests that the mean temperature of the Earth was significantly higher than it is today. Explain how the larger amounts of carbon dioxide in the Earth's atmosphere in the Eocene period could have caused Earth's mean temperature to be higher than it is today.
