By the year 2100, global temperatures are expected to rise by between 0.8 and 3.5 degree Celsius. That may not seem like much, but such an increase in temperature would cause a rise in sea levels large enough to put the lives of up to 100 million people at risk.
For the first time in the scientific community, there is total agreement that the activity of humans is at least partly responsible for the problem—specifically the emission of greenhouse gases like carbon dioxide, which is released by the burning of wood, coal and petroleum products. Reducing harmful emission is just one area in which the United Nations Intergovernmental Panel is decidedly optimistic. In the short term it might not prove that difficult. Efficiency improvements alone could cut energy needs by as much as 30 percent at virtually no extra cost and, in developed countries, emission reductions of up to 60 percent "are technically feasible". In the longer term, harmful emissions will be reduced as the world changes over to cheaper, less environmentally damaging energy sources.
选项
答案
到2100年,地球的温度预计将上升0.8到3.5摄氏度。这似乎不太多,但这样的升温将导致海平面大幅度上升,足以使多达一亿人的生命受到威胁。 科学界首次达成共识:人类的行为至少要对这一问题负部分责任——尤其是像二氧化碳这样的温室气体的排放,二氧化碳是由木材、煤以及石油产品的燃烧释放的。减少有害气体的排放只是联合国政府间专家小组明显感到乐观的一个方面。短期内,没有证据证实那样做有困难。只靠提高效率就能降低30%的能源需求,实际上也无需额外的花费,并且在发达国家,减少多达60%的有害气体排放“在技术上是可行的”。从长远看,随着全球转向利用那些更便宜、对环境影响更小的能源,有害气体的排放将会减少。
