How might the collapse of the Carboniferous rainforests have affected Earth's carbon cycle?

The collapse of the Carboniferous forests have influenced the carbon cycle of the Earth in the following ways:

1. The reduction of the Carboniferous rainforest would have declined the concentration of carbon in the Earth's carbon cycle.

2. Again the concentration of the carbon in the carbon cycle of the Earth would have elevated as a consequence of the decay of the vegetation.

3. The decaying vegetation was probably to minimize due to the captivation of the carbon dioxide from the atmosphere.

4. These decaying vegetation could have converted or transformed into fossil fuels after getting buried underground.

Atmosphere and climate. There are several hypotheses about the nature and cause of the Carboniferous Rainforest Collapse, some of which include climate change ... The carboniferous period is characterised by the formation of coal deposits which were formed within a context of the removal of atmospheric carbon.
