2、 the news,on whether global warming is real.But climate scientists looking at the data and facts agree the planet is warming.While many view the effects of global warming to be more substantial3 and more rapidly occurring than others do,the scientific agreement on climatic changes related to global

3、warming is that the average temperature of the Earth has risen between 0.4 and 0.8 over the past 100 years.The increased amounts of carbon dioxide and other greenhouse gases released4 by the burning of fossil fuels,land clearing,agriculture,and other human activities,are believed to be the main sour

4、ces5 of the global warming that has occurred over the past 50 years.Scientists carrying out global warming research have recently predicted that average global temperatures could increase between 1.4 and 5.8 by the year 2100.Changes resulting from global warming may include rising sea levels due to

5、the melting of the polar ice caps,as well as an increase in occurrence of storms and other severe weather events.譯文:全球變暖是一個用來描述地球大氣和海洋平均溫度逐漸升高的術(shù)語,人們認為這一變化將永久性地改變地球的氣候。關(guān)于全球變暖是否真的存在,很多人都有很大的爭論,有時甚至在新聞中也有。但是氣候科學(xué)家在研究數(shù)據(jù)和事實后一致認為地球正在變暖。雖然有許多人認為與其他相比,全球變暖的影響更嚴重,發(fā)生的速度也更快,但與全球變暖有關(guān)的氣候變化的科學(xué)共識是,在過去100年里,地球的平均氣溫上

6、升了0.4至0.8攝氏度。化石燃料燃燒、土地開墾、農(nóng)業(yè)和其他人類活動所排放的二氧化碳和其他溫室氣體的增加,被認為是過去50年來全球變暖的主要原因。從事全球變暖研究的科學(xué)家最近預(yù)測,到2100年,全球平均氣溫可能會上升1.4至5.8攝氏度。全球變暖帶來的變化可能包括極地冰蓋融化導(dǎo)致的海平面上升,以及暴風雨和其他惡劣天氣事件的增加?！驹~海拾貝】 1.term /tm/ n.術(shù)語2.permanently /pmnntli/ adv.永久地3.substantial /sbstnl/ adj.重大的4.release /rIlis/ v.釋放,排放5.source /ss/ n.來源【理解誘思】 Which of the following statements is TRUE?A.Everyone agrees that the globe is warming.B.Carbon dioxide emissions are responsible for global warmin
