科学家们担忧，如果超过上述水平，那么放大气温上升的“反馈”效应，可能导致气候变化失控即气温上升速度迅速加快，并造成更严重的风暴、土壤沙化、以及农业大幅减产等影响。

Scientists fear that at levels above that , the likelihood of " feedback " effects which amplify temperature rises could result in runaway climate change - a rapid acceleration in temperature and effects such as more violent storms , desertification and a sharp reduction in agricultural productivity .
