Answer:
The most common thing that happens to excess heat in the atmosphere is that it is absorbed by the oceans. The oceans have a huge capacity to store heat, and they have been absorbing more and more heat over the past few decades. This is due to the fact that the atmosphere is warming, and the oceans are not able to release the heat back into space as easily. As a result, the oceans are becoming warmer, and this is having a number of negative impacts on the planet, including sea level rise, ocean acidification, and changes in marine life.
Another thing that can happen to excess heat in the atmosphere is that it can be redistributed around the globe. This is because the atmosphere is constantly moving, and heat can be transferred from one place to another. This can lead to changes in weather patterns, such as more extreme weather events.
