The REAL culprit should be that fireball 93 million miles away called the Sun. Remember, the Sun's has a huge range of energy output, and changes in various types of energy output could change the Earth's climate quite dramatically--for example the famous Maunder Minimum from 1645 to 1715, when the sunspot count essentially went to near zero.

The SUN is 13 million times larger than Earth. Think about that and tell me what controls our climate.
