Question

When analyzing the ice core, the scientists discovered that the carbon dioxide (CO2) levels in the atmosphere were much lower than they are now. Since CO2 is a greenhouse gas, what does the lower CO2 level in the past say about our current climate?

Answer 1

Answer: Greenhouse gases trap heat from the Sun, keeping it within the atmosphere. The trapped heat means that the climate on Earth is likely warmer than it was during the ice age.
