Since 1995, the United States has had a trading system for sulfur emissions that cause acid rain. But some companies think other ideas, like new taxes on polluters, are a better way to cut greenhouse gases. Any new rules would hit some industries harder than others. For example, forty percent of the carbon dioxide from American industry comes from power producers, especially those that burn coal. The United States is the world's biggest producer of carbon dioxide, followed by China.On February second, in Paris, a scientific group established by the United Nations plans to release a major report on climate change. The report, six years after the last one, is expected to take the strongest position yet about the influence of human activity. The group is said to be at least ninety percent sure that human activity is the main cause of global warming in the last half-century. The Intergovernmental Panel on Climate Change puts most of the blame on the burning of fossil fuels. And the report is expected to say that scientists around the world believe temperatures will continue to rise.
1.sulfur emissions-emittions硫磺+拼写
2.polluters-pollutors拼写
3.position-poistion拼写，第二次犯错
4.fossil-fossile拼写
5.temperautre-tempatures拼写
从1995起，美国就有了防止硫磺排放导致酸雨而产生的交换系统方式。但一些公司认为采取诸如对污染者征税制度减少温室气体排放的方式更为有效。任何新的规定都会对某一群体产生更大的冲击。比如，在美国，40%的工业二氧化碳来自于电力部门，尤其是那些使用燃煤的企业。美国是全球排放二氧化碳气体最多的国家，紧随其后的是中国。2月2日在巴黎，一个由联合国组建的专家小组计划公布一份关于气候变化的重要报告。本次报告继上一份报告有六年之久，旨在表明人类活动对气候影响的程度。据说这个小组有90%的把握认为人类活动是导致上半个世纪全球变暖的主要原因。气候变化国际专家小组将主要原因归咎于石油燃烧。报告还预计世界各国的科学家都持全球仍会继续变暖这一观点。
