Curbing global warming

This year Beijingers had to shed their warm winter woollies and switch to skirts and short-sleeved T-shirts in early April.
Statistics show Beijing's average temperature from April 7 to April 16 was 18.8 C, 5.2 degrees higher than the figure for the same period last year and the highest since 1951. Although meteorologists have given reasonable explanations for the occurrence of such high temperatures, climatic change is becoming more and more a matter of public concern.
"Climatic changes, which are mainly seen in the gradual warming of the earth's atmosphere, have a bearing on the lives of all of us," said Qin Dahe, head of the Chinese National Meteorological Administration, at a forum held by Foreign Affairs College. "Industrialization is a direct cause of the greenhouse effect," he said.
Industrial production is now a global phenomenon, with fossil fuels being exploited and burned on a massive scale. Industrial waste products are not being properly treated before release. And even the large-scale development of agriculture can contribute to the exacerbation of the greenhouse effect.
A lot of greenhouse gases are still being released into the atmosphere, such as carbon dioxide, methane and nitrous oxide. Carbon dioxide alone accounts for 63 per cent of factors contributing to the rise in temperature of the earth's atmosphere.
According to Qin, the volume of greenhouse gases has doubled since the start of industrialization, resulting in a 1.2 C rise in temperature. Especially over the past 50 years, there has been an upsurge in atmospheric temperature, mainly caused by human activities.
In 2001, China experienced its 16th abnormally warm winter. In China's northeastern, northwestern and northern areas, temperatures have generally risen. And at the same time, precipitation in the country's northern areas has decreased. Hence, Beijing's record-high temperatures this spring are not altogether a surprise.
Atmospheric warming is also having a deleterious effect on the earth's ecological systems. Patterns of vegetation have been changing, and biodiversity is decreasing. Glaciers have generally shrunk and lake levels fallen. On the other hand, the levels of the world's oceans are rising. And extreme weather patterns have begun to pose serious challenges to human life.
In addition to the ecological system, social and economic systems have also been hurt.
With agriculture, output levels, distribution and costs have all been affected. And supplies of water have continued to decrease since precipitation has been negatively affected. The annual runoff volume has declined by 3 per cent.
The issue of atmospheric warming is attracting attention worldwide. And the international community is now making efforts to control the emission of greenhouse gases.
In 1992, the United Nations Frame Convention on Climate Change (UNFCCC) was adopted. It was the first international convention, aimed at stabilizing greenhouse gas concentrations in the atmosphere at a level that will prevent dangerous human interference with the world's climate system.
The convention also requires developed countries to pay all developing countries' costs in cutting emissions and adapting to climate changes; and developed countries should support the strengthening of developing countries' ability to deal with environmental problems, including the transfer of related technology.
In 1997, more than 160 countries met in Japan to negotiate binding limitations on greenhouse gas emissions in developed countries. The outcome of the meeting was the Kyoto Protocol, in which developed countries agreed to cut back their greenhouse gas emissions to 1990 levels. But because of the refusal of the United States to sign, the protocol is still not in effect.
With a full realization of its environmental problems, China has also done a lot of work to improve its environment and avoid repeating the western countries' perversion of priorities, expressed in the phrase, "pollution first and then control."
China actively participated in the discussion and signing of the UNFCCC and the Kyoto Protocol, committing itself to the fulfilment of its responsibilities.
However, as a developing country with a rapidly growing economy, China is facing a tough challenge in controlling its emission of greenhouse gases.
Currently, although its emission per capita is lower than the world average, China's release of carbon dioxide ranks second in the world. And the warning is out that the country will become the number one emitter of carbon dioxide by the year 2030.
In addition, China's urbanization level still stands at 31 per cent, far below the world average of 46 per cent. Pushing forward the country's urbanization level will require the consumption of more fossil fuels, given that not enough effort is being made to develop new types of clean energy.
Despite difficulties, China should have some success in limiting its emission of greenhouse gases.
As clean forms of energy are not yet widely used in the country, the government should work out a strategy to optimize the energy structure. At present, coal accounts for 70 per cent of China's energy production.
Research and development should be carried on to develop more kinds of recycled energy and to develop hydropower or nuclear energy, which do less damage to the environment.
It is also important for the government to seek a balance between emissions control and poverty alleviation, while developing the economy.
On the other hand, the public should be made more environmentally aware. More effort should also be made to teach the public ways to protect the environment in the course of their daily lives.

Great Point. Is it a double standard yes. Will Big Al Gore ever admit to it NO. I think that those people who choose to stick there heads in the sand to the reality of Radical Islam being a plague, have come up with the theory of global warming because their butts are getting a sunburn.

Disagree. Even if every single person in China went out and bought a car tomorrow - even the little babies, it would only cause a 50% increase in the number of vehicles worldwide.
All cars in the world contrinute 9% to global warming so with avery Chinese person acquiring a new car would increase levels by a further 4.5% (that's assuming that everyone bought a car, that nobody already has a car and that they manage to afford to drive it the same number of miles as the average motorist).

I'm not too happy with the fact that china doesn't care about its people, its environment or its animals. china needs to get a grip, love its people, respect its environment (like getting cleaner fuels, and upgraded factories and fuel-burning methods) and realize that animals need someone to speak up for them because they cant speak for themselves. china is a selfish country, taking anything and everything it can without return (if it doesn't benefit them). china, get a clue, its not all about you. you had best respect your environment and surroundings, because you have the largest human population - if you dont clean up your act then your country will fall ill from its poverty, poor sanitation methods, outdated fuel burning methods and lack of respect in the population as being one.

No.
First, I--and most Americans--are sick and tired of the right-wing trying to avoid responsibility for THEIER actions by pointing the finger at what others do. Your actions are YOURS--and its up to you to correct them. And you have no business criticizing others until you do (and if you claim to be a Christian--that's straight out of the Bible).
As for China, first, there are effective technologies--which at this point they aren't using (and because of the Bush administration aren't being pressured ). But here's the bottom line: if they want to sell us goods, we can demand they clean up their act, or do without access to our markets. Want to guess how long it would take Beijiing to change their energy policy?

I'm confused...why do you think the people in China are going to dump their bikes? They're putting less emissions in the air per person than the US....

I am even more concerned about it because of that. Yes we need 9,000,000 bicycles in bejing it has helped our global environment

global warming coming. i believe that no matter how hard we try to stop global warming, it may decrease the percentage, but it will come someday. just living our daily lives erases the memory of tomarro.
