As carbon dioxide gas levels in the atmosphere increase, the temperature will
1. decrease
2. increase
3. stay the same.
4. The temperature on Earth is not affected by carbon dioxide gas.
Carbon dioxide acts as a greenhouse gas that keeps the heat of the Earth from escaping back into space, much like how the glass of a greenhouse makes it nice and warm and steamy for plants.
when carbon dioxide concentrations rise, air temperatures go up, and more water vapor evaporates into the atmosphere—which then amplifies greenhouse heating.
