地球大气层正在转暖,这种迹象日趋明显,这向人们提出了一个重大问题,即:地球变暖在多大程度上应归咎于人类的活动,又在多大的程度上是自然原因引起的?科学家正在寻求答案,但是进展缓慢.
联合国设有关于气候变化的政府间专门小组,由这一领域一些公认的权威科学家组成.该小组断定:全球气候受到了“显而易见的人为影响”.目前,该专门小组又一次开展了对全球气候变化的全方位定期科学评估.
一些专家认为,人类对气候的影响愈益明显,甚至可能是近几十年来全球变暖的主导因素.但是,这一观点并非人人赞同,而几乎所有专家都承认,不管怎样,准确评价人类对气候的影响程度有待时日.
Earth's atmosphere is warming,this sign is increasingly clear,and this to the people raised an important question,namely:global warming,the extent to which should be attributed to human activities,and the extent to which they are caused by natural causes?Scientists are seeking answers,but progress has been slow.
With the United Nations on climate change,the Intergovernmental Panel,some of this area recognized by the authority of scientists.The group concluded that:the global climate by the "obvious human impact." At present,the panel once again carried out on global climate change,and all-round regular scientific assessment.
Some experts believe that human influence on climate has become more obvious,and probably the global warming in recent decades the dominant factor.However,not everyone agreed with this view,almost all experts believe that,in any case,the accurate evaluation of human influence on climate有待时日degree.
