Answer 1

The most likely effect would be:

The temperature of Earth’s surface would decrease because more heat would escape into space.

This is because carbon dioxide is a greenhouse gas that helps trap heat in the atmosphere. A decrease in carbon dioxide concentration would result in less heat being retained, leading to a cooling effect on Earth's surface.
