【正文】 第一篇：初中英語演講稿At first, you must understand the meaning of climate means any longterm significant change in the average weather, which may include average temperature, precipitation, wind patterns and so example, Australia is experiencing rapid climate 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 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 this example, it indicates climate change that is occurring today has sped up, and affects longterm Earth’s climate is largely affected by how much heat is stored in the , the climate change is caused by dynamic process on Earth, external forces including variations in sunlight intensity, and more recently by human most important reason of climate change is caused by humans, because humans produce a lot of carbon dioxide into the carbon dioxide emits from fossil fuel, aerosols, cement manufacture, land use, animal agriculture and example, trees can take in carbon dioxide to produce oxygen by people cut many trees for making furniture, paper, or sell wood to make money, there is much more carbon dioxide in the with the industrial revolution in the nineteenth century and accelerating ever since, the human consumption of fossil fuels has raised carbon dioxide levels means that carbon dioxide levels are substantially higher now than the other hand, during the procedure of manufacturing cement, which is used in buildings, significantly more carbon dioxide is people improve their living standard, they cause climate people burn coal, oil, and gas for our electricity, carbon dioxide is people burn fossil fuel to move vehicles, carbon dioxide is also sorts of examples indicate that humans are the real do not consider the consequence, while they enjoy producing every thing they is not just manmade pollution of the atmosphere which can cause climate in the amount of carbon dioxide in the air have occurred naturally during the history of the Earth, leading to climate a volcano erupts, it releases huge amounts of carbon dioxide and sulfur dioxide into the , volcano eruptions cannot effect climate main reason is that before the volcano erupts, it would release huge amount of carbon dioxide and sulfur dioxide for a very long pollution injected into the air blocks out a lot of , it can cause the Earth to cool over fewer 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 movement of the Earth’s axis also affects climate change。it moves a little more than a halfdegree each processes can change the Earth’s climate over millions of 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 addition, changes in the way ocean water circulates around the world can affect the climate, because the oceans store even more heat than the ocean currents change direction, slow down, or reverse, it has a significant impact on change is mainly caused by carbon can be separated to two important parts: natural causes, and human 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.第二篇：初中英語演講稿Good morning teachers and fellow we would like to introduce a few favorite books to favorite book is
