What happens when the sun emits more energy than normal?

there is a little higher end of temperature experienced on the surface of earth.

Explanation:

The sun emits electromagnetic energy which falls on earth in the form of radiation. The energy is emitted as rays and travels through space at the speed of light. The sun is in stable state and at times shows higher than normal activity which is detected as sunspot. During this phase, more energy reaches earth. At that time, more energy gets absorbed heating the earth surface and changing climates.  

Though some part of energy falling on earth are reflected back to atmosphere, some gets trapped in between the atmosphere due to carbon dioixde presence. These trapped gases are source for greenhouse effects.

On the basis of the above explanation is:  

When the sun emits more energy than normal, there is a little higher end of temperature experienced on the surface of earth.
