In the past few years,"the hottestsummer in history"often appearinour vision. In2013,this"record"is refreshed once again.TakeShanghai as an example, days over38℃inJulyaloneas high as24days. The Shanghai Publisher（Sina Weibo account）announcedthe hottest day in this summer was40.6℃. According to the record of the past century, itmight be the hottest day in the meteorological record. Feeling thewarmsuninthesame time,peoplecannot help butcomplain that"howtheweatherwould be?"Under such complaining about the weather and the horrible temperature, the mosthypostatic question is “global warming”. What people constantly discuss is whether globalwarming really exists, but whether it really has deteriorated. Meanwhile, people started tofocus on what makes people live so hard, the greenhouse gases or the sun, even theearth itself.In fact, although generally accepted global warming’s exist in academia, the reasonwhat raised it is still a mystery.“Introduction of Environmental Science”, the textbook ofenvironmental science, took us both the man-made and natural factors have effect on it.Factors of human beings as greenhouse gas emissions, the destruction of vegetation.Natural factors as solar activity cycle, etc.[1]In this circumstance, news reports aboutglobal warming are also various. As an audience, how to make their own judgment, whatfactors led them to build the worldview of such problem become a veryinterestingdiscussion topin.This study will involve the knowledge of journalism, communication, psychology,environmental, etc. The combination of environmental and journalism started in19thinUS(The Conservation Movement), and went to mature in1960s. If the psychology can becombined wit environmental and communication, it will be more finesorted subject. The study will usesurveymethods to get the answer fromone-sidedargumentsmessage text, perceived-control which cause people to get thedetermination. The study found: different message and the level of perceived-controlwillaffect the decision. Mainly as follows:(1) a high perceived-control believedthe cause ofglobal warmingis man-madefactors, andlow perceived-controlis considered tobetestedbynatural factors;(2) to readnatural factorsarecausingglobalwarmingmeasurementconsiderednaturalfactors,as well human factorsmeasured bythereadingof globalwarmingisthought to bethe human factor;(3) in theperceived-control-informationtype Crossfactors, theimportance of perceived-control ishigher thaninformation type. Experiments show that perceived-controlas alever, it shouldbe a relativelysignificant role inthedecision about how people thinkingthe reasonof globalwarming.
