The Earth would end up cooler than before the human influence, as feedback processesoppose the tiny warming caused by the change in atmospheric composition.B.The Earth would end up a few tens of degrees warmer than before the human influence,because positive feedbacks would amplify the original changes a whole lot.C.The Earth would end up one degree warmer than before the human influence, becausepositive and negative feedback processes would offset each other.D.The Earth would end up a few degrees warmer than before the human influence, becausepositive feedbacks would amplify the original change.E.The Earth would end up warmer than before the human influence but by less than onedegree, because feedback processes would oppose the initial warming
