Answer 1

The correct comparison would be:

There is now more oxygen, increasing temperatures, and increasing carbon dioxide.

Early Earth had a much different atmosphere, primarily composed of nitrogen, carbon dioxide, and little to no oxygen. Over billions of years, photosynthetic organisms produced oxygen, significantly increasing its concentration in the atmosphere, leading to a more oxygen-rich environment. Additionally, modern-day action, such as burning fossil fuels, has led to increased carbon dioxide levels and rising global temperatures.
