Chemistry
Answer
CO2
Reason — CO2 is a greenhouse gas. It traps some of the heat coming from Earth and helps keep our planet warm.
O2 is needed for respiration, but does not trap heat significantly. N2 is a major component of air, but does not contribute to warming. Ne is an inert gas but has no role in warming.
