The global carbon cycle is a very important component of the global climate system, with several feedback mechanisms that make its behavior complex. What are some of the main negative feedbacks and positive feedbacks in the carbon cycle?
Some of the main positive and negative feedbacks in the carbon cycle are:
Positive- if ice and snow melts this will cause the earths surface to absorb more energy because soil and ocean water is more exposed, this then can cause frozen soil to release large amounts of CO2, the warming of the earth can cause water vapor which is a powerful green house gas, all in all this is a continuous cycle adding up to global warming.
Negatives are that too much evaporation can cause more cloudiness which will block the sun reflect solar energy away from earth which can then cause reduced global warming and there is no cycle.
