1 环境的变化与建筑的责任近百年来,人类不文明的活动方式导致地球环境发生了某些巨大的变化,其中有些是全球性的,如气候的变化便是其一。以前大气中 CO_2的含量一直维持在280ppm,而近几十年来,大气中CO_2的浓度迅速上升,达到370ppm。与此同时,全球平均气温也上升了,从1980年起至2000年,上升约0.38℃。NSAS 的专家 Jawes Hansen 指出,毫无疑问这是人类活动排放的气体导致了气候的变暖。“UKCIP02概要”文件对英国气候变化进行了
1 Changes in the Environment and Responsibility for Construction Over the past century, the uncivilized manner of human activities has led to some dramatic changes in the Earth's environment. Some of them are global. For example, climate change is one of them. Before the atmospheric CO 2 content has been maintained at 280ppm, and in recent decades, the atmospheric CO 2 concentration rapidly rose to 370ppm. At the same time, the global average temperature also increased, rising by about 0.38 ° C from 1980 to 2000. Jawes Hansen, an NSAS expert, points out that there is no doubt that this is the result of climate change caused by gas emissions from human activities. “UKCIP02 Summary ” document on the British climate change
