The answer is D. Carbon dioxide is an insignificant greenhouse gas. Carbon dioxide is actually a significant greenhouse gas and contributes greatly to the global warming seen on Earth. One example is seen on the hottest planet in the Solar System, Venus. 96.5% of Venus's atmosphere is Carbon dioxide, heating the planet to a balmy 872 degrees Fahrenheit from the greenhouse effect of that gas.
