 * //Topic: Human influence on climate change//**

=
As is known to all,global warming is a worldwide problem today.It refers to the rising temperature of Earth's atmosphere and the ocean in this century,which is mainly caused by human-induced activities,such as burning of coal and other industrial practices.The concentration of atomospheric greenhouse gases(eg.CO2 and CFCs)and other air pollutions have severely increased due to these actions .Here are some websites on climate change and human impact. [] & [] I also recommend the book written by former US Vice President Al Gore--"An Incovenient Truth"and its same name movie.Both of them are excellent resources for enviromentalists. http://v.youku.com/v_show/id_cd00XMTQzNDA1Mjg=.html======

It's obvious that climate change is a big topic in UN.
**//Hours of darkness to fight climate change//** [] On March 29,UN shut off lights because of Earth Hour as well as mobilizing global support for a new UN agreement on climate change.Earth Hour was launched two years ago in Australia by WWF. This program talks about taking simple steps everyday to collectively reduce carbon emmissions--from businesses turning off their lights when their offices are empty to households turning off appliances rather than leaving them on standby.UN climate chief also called upon everyone to join in Earth Hour. //"We are on a dangerous path," the UN chief said. "Our planet is warming. We must change our ways. We need green growth that benefits communities. We need sustainable energy for a more climate-friendly, prosperous world."//

Two years ago,Sydney was the only participant.Two years later,with the rising awareness toward the need to take action on climate change,more and more of us are actively engaged in it.Driven by a sense of urgency facing the serious realities, our society is taking responsibility. I think what UN has done is not only a "symbolic action",the result of Earth Hour will not only have marginal effect on reducing greenhouse emissions.The reason why UN advocated this event so much is mainly due to it drawing attention to environmental problems caused by excessive use of energy,therefore calling for each individual to start paying attention to small details.

//** Developing nations fear for higher emission exports []**// This March featured negotiations toward a new global climate change agreement .Delegates of 192 members from the UNFCCC met in Bonn,Germany starting on the 29th of March to begin the work on drafting a negotiating text for the new agreement.The world now is still striving for a new UN climate "treaty" to succeed Kyoto Protocol.In the meeting,developing nations said that export would suffer if rich states put up import barriers to penalise their emissions from burning fossil fuel.International policies senior advicer pointed out that developing country steel exporters,such as China,India or South Africa,risked trade penalties since their factories were less efficient and emmitted more greenhouse gases than those in developed nations.Some other developing countries said that developed nation schemes for "eco-labelling"--marking goods with the amount of greenhouse gases --could discourage exports of products that are flown or shipped over long distances.

As far as I am concerned,there will be more and more overlap between trading and climate issues.Many countries now consider the inclusion of tariffs in the country's climate change policy,which restricts the exports a lot by the heavy cost for cutting carbon.If a company's cost on carbon elimination goes up dramatically,they will lose their competitiveness,which also indicates that more people will lose their jobs,states lose manufacturing.Firms would like some guarantee so that their businesses are not likely to suffer from high cost of a climate change bill.

The goal of my journal is to investigate how serious the problem now appares therefore calling for the firm action from everyone.I will also pay attention to what is new in UN's latest approaches on this issue.There is no doubt that the effect of climate change has already threatened the existance of mankind.What UN and we should do is to search for an operational and long-standing solution to solve this problem.Facing the worsen situation of climate change,it reminds me of a famous saying--'The greatest threat to mankind is mankind itself.'Here,I am merely pointing out that the greatest source of pollution is no other than human beings.Only when both companies and individuals properly decipline their behaviours can the influence from human be in control,and that is not all.

We are not only setting our vision on a low cabon-emmission world.We are looking forward to the one which not only ensures a secured climate but can sustain economic growth worldwide.Apparently,climate issues are closely bound up with the development of technologies and the construction of social environment.As UN Secretary-General BAN Ki-moon said, //greatly enhanced investment in renewable energy and energy efficient technologies cannot only put the Earth onto a sustainable track,it can generate employment and growth on an impressive scale.//The world is watching and wating;we,as the young generation especially MUN-ers,should not dissapoint them.
