Obviously solar input dominate over whatever energy we add through burning fossil fuels. Nobody contests that. You must have heard of the greenhouse effect.

Obviously solar input dominate over whatever energy we add through burning fossil fuels. Nobody contests that. You must have heard of the greenhouse effect. THAT is the issue. By changing the composition of the atmosphere, a fractionally greater percentage of the astounding amount of energy is reflected back to the earth instead of escaping into the atmosphere, raising the temperature of the atmosphere and oceans. Imagine sitting in the sun on a warm but not hot day. Now imagine you are sitting in a car in the same spot in the same conditions with the windows rolled up. There is no extra energy being released, just the plain old sun, but the temperature you experience is going to be much higher. Indeed, the temperature increase doesn't grow without bound, but it is meaningfully higher.
