的确，这项研究实际上很可能还大大低估了相关成本：例如，气候变化会引起天气的更大可变性，可能造成墨西哥湾暖流的变化消失—欧洲特别担心的问题—并引发大量的疾病。
Indeed, the study may actually significantly underestimate the costs: for instance, climate change may lead to more weather variability, a possible disappearance or major shift of the Gulf Stream – of particular concern to Europe – and a flourishing of disease.
