At first, you must understand the meaning of climate change. It means any long-term significant change in the average weather, which may include average temperature, precipitation, wind patterns and so on. For example, Australia is experiencing rapid climate change. Since the middle of the twentieth century, Australian temperatures have risen by about average one temperature degree with an increase in the frequency of heat waves and a decrease in the numbers of frosts and cold days. Rainfall patterns have also changed, which means that the northwest has seen an increase in rainfall over the last fifty years while much of eastern Australia and the far southwest have experienced a decline. From this example, it indicates climate change that is occurring today has sped up, and affects long-term weather. The Earth’s climate is largely affected by how much heat is stored in the atmosphere. Furthermore, the climate change is caused by dynamic process on Earth, external forces including variations in sunlight intensity, and more recently by human activities.
The most important reason of climate change is caused by humans, because humans produce a lot of carbon dioxide into the air. This carbon dioxide emits from fossil fuel, aerosols, cement manufacture, land use, animal agriculture and deforestation. For example, trees can take in carbon dioxide to produce oxygen by photosynthesis. If people cut many trees for making furniture, paper, or sell wood to make money, there is much more carbon dioxide in the air. Beginning with the industrial revolution in the nineteenth century and accelerating ever since, the human consumption of fossil fuels has raised carbon dioxide levels rapidly. It means that carbon dioxide levels are substantially higher now than before. On the other hand, during the procedure of manufacturing cement, which is used in buildings, significantly more carbon dioxide is produced. While people improve their living standard, they cause climate change. When people burn coal, oil, and gas for our electricity, carbon dioxide is produced. When people burn fossil fuel to move vehicles, carbon dioxide is also produced. These sorts of examples indicate that humans are the real culprit. They do not consider the consequence, while they enjoy producing every thing they want.
It is not just man-made pollution of the atmosphere which can cause climate change. Changes in the amount of carbon dioxide in the air have occurred naturally during the history of the Earth, leading to climate changes. When a volcano erupts, it releases huge amounts of carbon dioxide and sulfur dioxide into the atmosphere. However, volcano eruptions cannot effect climate change. The main reason is that before the volcano erupts, it would release huge amount of carbon dioxide and sulfur dioxide for a very long time. This pollution injected into the air blocks out a lot of sunlight. Therefore, it can cause the Earth to cool over fewer years. For example, in April 1991 eruption of Mount Pinatoba, where is in the Philippine islands, emitted huge amounts of carbon dioxide and sulfur dioxide into the air. The movement of the Earth’s axis also affects climate change; it moves a little more than a half-degree each century. Other processes can change the Earth’s climate over millions of years. When not only continents move around the world, but also mountains ranges are built, the changing patterns of landmasses affect the way the heat in the atmosphere and in the oceans is stored. In addition, changes in the way ocean water circulates around the world can affect the climate, because the oceans store even more heat than the atmosphere. Once ocean currents change direction, slow down, or reverse, it has a significant impact on climate.
Climate change is mainly caused by carbon dioxide. This can be separated to two important parts: natural causes, and human causes. After we realise what the two important factors of climate change are, and what the climate change is, we could try to think of a more effective solution to solve the climate change problem to make a higher quality environment.

“Once upon a time， there was a king who had a daughter as beautiful as a blooming rose. To all the suitors who came to the king's palace to ask for the hand of the princess, the old king assigned three tasks to be accomplished, each next to impossible. One day, into the king's palace came a handsome young prince…" Well, you know the rest. The three tasks may be different in different versions, but the main plot is always the same, with the prince claiming the princess's hand triumphantly.
And the ending is always the same, finishing with the line "And they live happily every after."
Why aren't we tired of something so fanciful, so unrealistic, and, I would say, so unimaginative? How can a story like that endure generations of repetition`? Because, I think, it is a typical success story. It is highly philosophical and symbolic. By implication, we see a 4-step definition of success: 1 ) a goal to be set. as represented by the beautiful princess; 2 ) challenges to be met, as represented by the three tasks; 3 ) the process of surmounting difficulties, as represented by the ordeals the youth goes through; and 4 ) the reward of success, as represented by the happy marriage.
The story not only caters to everyone's inward yearning for success, but also emphasizes the inseparability of the process and the result. The reward of success will be much amplified if the path leading towards it is treacherous, and vice versa. If a person inherits his father's millions and leads an easy life, he is not a successful person even in material terms, because there are no difficulties involved in his achieving affluence. The term "success", to be sure. will not sit still for easy definition. But as I understand it, the true meaning of success entails a combination of both the process and the satisfactory result of an endeavor. To clarify my view, let me give another analogy.

John in order to choose the wise after the death of his home, he visited the heaven and hell
He first came to the hell, to see all the people are sitting at the table, the table filled with all kinds of delicious foods. The strange thing is, they are all one in the blues. John emaciation with sallow complexion, a closer look only to find the original table on the left arm people are tied with a fork, right arm tied with a knife, knife the fork and handle up to 4 feet, grasp the knife and fork to eat all the things on the table, so they only watched the food hungry.
John went to heaven, and all the way to find dining equipment with hell. But people here are as like as two peas ruddy, and everywhere is full of laughter. John felt very strange, why they are not afraid of hunger? John quickly found the answer, the original heaven never handle food to feed themselves but, happily to others to eat, so, who can eat delicious food; and hell who only want to feed themselves, so only to starve.
Heaven and hell have only one step away, but because of the warmth and love between people, heaven has become a place for laughter, the hell became a place full of complaints and hunger

honorable judges, fellow students: good afternoon!
recently, ther is a heated debate in our society. the college students are the beneficiaries of a rare privilege, who receive exceptional education at extraordinary places. but will we be able to face the challenge and support ourselves against all odds? will we be able to better the lives of others? will we be able to accept the responsibility of building the future of our country?
the cynics say the college students are the pampered lost generation, which would cringe at the slightest discomfort. but the cynics are wrong. the college students i see are eagerly learning about how to live independently. we help each other clean the dormitory, go shopping and bargain together, and take part time jobs to supplement our pocket money.
the cynics say we care for nothing other than grades; and we neglect the need for character cultivation. but again, the cynics are wrong. we care deeply for each other, we cherish freedom, we treasure justice, and we seek truth. last week, thousands of my fellow students had their blood type tested in order to make a contribution for the children who suffer from blood cancer.
as college students, we are adolescents at the critical turning point in our lives. we all face a fundamental choice: cynicism or faith, each will profoundly impact our future, or even the future of our country. i believe in all my fellow classmates. though we are still inexperienced and even a little bit childish. i believe that we have the courage and faith to meet any challenge and take on our responsibilities. we are preparing to assume new responsibilities and tasks, and to use the education we have received to make our world a better place. i believein our future.

And I know what you're thinking. You know, I'm up here bagging out inspiration, and you're thinking, "Jeez, Stella, aren't you inspired sometimes by some things?" And the thing is, I am. I learn from other disabled people all the time. I'm learning not that I am luckier than them, though. I am learning that it's a genius idea to use a pair of barbecue tongs to pick up things that you dropped. (Laughter) I'm learning that nifty trick where you can charge your mobile phone battery from your chair battery. Genius. We are learning from each others' strength and endurance, not against our bodies and our diagnoses, but against a world that exceptionalizes and objectifies us. I really think that this lie that we've been sold about disability is the greatest injustice. It makes life hard for us. And that quote, "The only disability in life is a bad attitude," the reason that that's bullshit is because it's just not true, because of the social model of disability. No amount of smiling at a flight of stairs has ever made it turn into a ramp. Never. (Laughter) (Applause) Smiling at a television screen isn't going to make closed captions appear for people who are deaf. No amount of standing in the middle of a bookshop and radiating a positive attitude is going to turn all those books into braille. It's just not going to happen.
