全球变暖

Ladies and gentleman:

Welcome to attend our international academic conference on global warming. I would like to express my thanks to you for your attendance.

As we know, our earth is having a fever. The consequences of global warming suggest that reducing global warming is not an easy affair.

First of all, citizens do not believe that global warming is a big deal. On one hand, citizens pay more attention to their personal affairs. They prefer to focus on their jobs and family life rather than global warming issues. In other word, people do not realize that it is their duty to deal with global warming. On the other hand, there is no convincing evidence showing that global warming will have harmful impact. For example, the seaport cities are still safe and prosperous now. The climate of the earth does not extremely change. The food supplies keep growing and the agriculture of the coastal area is still productive. So the residents of the seaport cities still feel easy and comfortable. In a word, people do not concentrate on global warming.

Secondly, the desperate need of energy will be a big obstacle of reducing global warming. In order to develop our economy, we have to make use of energy such as the burning of coal, oil, and wood, causing the temperature rise. As we know, economy is so important to our life that it is impossible to stop using energy. What can we do? Governments has put forward a series of policies to encourage people to use clean energy such as wind energy, water energy, nuclear energy and geothermal energy. But the proportion of using clean energy is extremely small so far.

Thirdly, most of the countries are not willing to pay much money to deal with global warming. The rich countries hold the opinion that it is everyone’s responsibility to deal with global warming, while the poor ones do not agree. The developing countries considered that developed countries should take more responsibility since they product more gas emissions. Lawmakers from the Group of Eight (G8) nations, together with five major developing countries, said many governments are doing too little to support their speech. For instance, United States refused to ratify the Kyoto Protocol to cut greenhouse gas emissions.

In a word, it needs a lot of cooperation between experts to reducing global warming.

Finally, I wish every success at this conference. Thank you!
