This article from the start with the greenhouse effect and a b rief analysis of greenhouse effect and as to the cause of global climate change and puts for ward some mitigation measures.Keywords: The greenhouse effect, Global warming, Carbon dioxide, Temperature Since the 1990s, with the progress of the industrial revolution, the development of science and technology, promote the progress of human civilization. But due to the large number of human use of coal, oil,natural gas and other fossil fuels, deforestation, land reclamation, the levels of greenhouse gases in the atmosphere increased, making the global greenhouse effect[1]. And the scientific research also shows that nearly a hundred years, the earth's climate is undergoing a significant change characterized by global warming. Predict that the next 50~100 years, the global climate will continue to develop in the direction to the warming, it will have a significant impact on the global natural ecosystem and the social economy of every country, so that the human survival and development is facing great challenges[2]. Therefore, study on the greenhouse effect and global climate change has a great attention in the world.1.the greenhouse effectThe greenhouse effect refers to the heat preservation effect of the sun and the formatio nof the confined space transmission due to the lack of heat exchange with the outside world, is the solar short wave radiation can through the air into the ground, long wave radiation an d surface warming after the release was absorbed by atmospheric carbon dioxide and other su bstances,thereby generating atmospheric warming effect[3]. Carbon dioxide in the atmosphere i s like a thick glass, so that the earth into a big warm house. If there is no atmosphere, the average surface temperature will drop to -23℃, and the actual surface average temperature of 15℃, which means that the greenhouse effect that the surface temperature by 38℃. To increase the concentration of carbon dioxide in the atmosphere, the earth's heat dissipation block, m ake the earth happened can feel the temperature rise, this is the famous "greenhouse effect".2.the global warmingSince nineteenth Century about 100 years the global surface temperature rised 0.2~0. 6℃, from 1880~1998 years of 119 year data, the trend of global warming was 0.53℃/100a [5]. Climate warming mainly occurred in 1920s~ 1940s, and the middle of 1970s. In the 80s’ t he trend of the global temperatures is accelerate rised , and the 1990, 1995, 1997 and 1998 t he average global temperature record several times[6]. According to the forecast twenty-first C entury global average temperatures will rise 1.5~4.5℃, in the northern hemisphere high latitu de regions will increase the temperature about 5~10℃, global temperatures will to 0.3℃/10a (0. 2~0.5℃) speed increase, which will enable the average global temperature rise speed to beco me in the past one hundred thousand years the highest[7]. Although the prediction of the am plitude of the warming is not the same, but it is certainly the future global temperatures wil l be rising trend.3.The causes of climate warmingPublic opinions are divergent. fundamental reason, global warming, which a view that at present the ball temperature increase is all caused due to the long-term variation of solar rad iation energy. Cosmic rays with the solar cycle changes, and interaction with the solar win d, solar wind over the earth directly influence the formation of clouds, which have an influ ence on climate.However, the global warming is caused by human factors are increasingly prevail[5]. Many scientists believe that human itself in its unreasonable industrial and agricultu ral production process, excessive energy consumption of fossil fuels, deforestation, land recla mation leads to a large number of CO2and other greenhouse gas emissions, and destroyed a large number of components of the natural ecological system and the important ecological processes, marine plants and other natural ecological systems have no ability to absorb all the excess produced gas greenhouse gases in the atmosphere,retention, like plastic film greenhous e, although it could not stop the sunlight reaches the ground, it can absorb and block the gro und potential into the sky from [5]. This greenhouse gas layer "quilt", still with annual 0.5% sp eed thickening. Many scientists believe that. in addition to human caused greenhouse effect, the emission of industrial harmful gas, vehicle exhaust and the use of pesticides and other factors, cannot be explained by global warming to find any other reason.4.SummaryPeople have started to realize the greenhouse effect caused by the intensification of hu man activities on a serious threat to human beings, global warming has been and will contin ue to influence the human survival environment, how to maintain the sustainable developme nt of the environment for human survival, slow down the bad influence caused by global w arming,has aroused strong concern of governments, scientists and the public.So far, we are unable to put forward effective solutions, but at least we should try our best to curb emissions growth, not resigned it rise arbitrarily. Therefore,we should take cou ntermeasures, try to suppress the rising trend. International public opinion is moving in this di rection continuously appeal, and research institutions have also put forward their specific cou ntermeasures national scheme.Such as: Ban chlorofluorocarbons, automobile fuel, reduce the u se of forest protection,improving energy increase exhaust gas and the development of new en ergy and other green area of biological method, restriction of automobile.Reference[1]程东来,钟学斌.温室效应与气候变化及人类活动的关系[J].咸宁学院学报,2008,28(6).[2]李培基.温室效应与气候变化[J].冰川冻土,1991,13(3).[3]柏永全.从可持续发展理论出发论温室效应与气候变暖[J].中国环境管理干部学院学报,2003,13(3).[4]戴君虎,晏磊.温室效应及全球变暖研究简介[J].世界环境,2001.[5]徐世晓,赵新全,孙平等.温室效应与全球气候变暖[J].青海师范大学学报(自然科学版),2001,(4).[6]刘晓东,侯萍.青藏高原及其部近地区近30年气候变暖与海拨高度的关系[J].高原气象,1998,17(3):245-249.[7]王绍武.近百年我国及全球气温变化趋势[J].气象,1990,16(2):11-15.评阅意见评阅成绩评阅教师：2014年月日。
