When the amount of carbon being released into the atmosphere is more than can be absorbed by carbon sinks, then the carbon cycle becomes unbalanced, resulting in a “runaway greenhouse effect”. This also happens when the levels of any other greenhouse gas are unbalanced.

Which planet do scientists think had a “runaway” greenhouse effect, leading to extreme present atmospheric temperatures?

The runaway greenhouse effect and its inverse, the runaway refrigerator effect, have led to harsh, uninhabitable conditions on Venus and Mars. Does the greenhouse effect always cause climate changes leading to loss of water and life? Give a reason for your answer.
