pidato english global warming


Assalamu'alaikum Wr Wb
Dear principal
I respect Mr / Mrs Teachers and Administrative staff
And friends whom I love

Lately talks about global warming increasingly crowded aka Global Warming discussed. What exactly is global warming? There is one interesting article you can read the following:

Global warming could be interpreted as a warming Earth's surface for some period of time. This is a normal natural phenomenon actually. If it does not get warm, temperatures on Earth could be freezing cold like the ice ages that have occurred 15,000 years ago.

Warming on Earth's surface known as the 'Greenhouse Effect' or the Greenhouse Effect. This process begins with the sun rays that penetrate the layer of air (atmosphere) and heats the Earth's surface.

Earth's surface to heat warms the air which is right on it. Because of the mild, hot air rises and replaced by cooler air.

Some of the hot air that rises to the top retained and reflected back to the surface by a layer of gases in Earth's atmosphere is composed of Carbon Dioxide, Methane and Sodium Oxide. Hot air reflected the function to keep the temperature of the Earth so as not to be frozen. The reflection process of hot air to warm the Earth is called the greenhouse effect.

But the natural processes that normally become unwell since humans entered the industrial process. At this time humans began burning coal, oil and gas to produce fuel and electricity. The process of burning energy from this Earth was to produce gas in the form of carbon dioxide emissions. Automatic, levels of greenhouse gas layer that holds and reflects heat back to Earth becomes more and more.

If the Earth is continuously exposed to warm up, another big danger will arise, or even already happening and we're feeling right now. The first effect is happening is the high air temperature. Communities in Western Europe in the months yesterday already feel how tortured life when the temperatures become extremely hot. The number of victims who died due to 'overheating' in the hundreds, not counting who have experienced hospitalization because of dehydration. It's not a trivial problem.

Increasing temperatures could melt much snow at both poles of the earth and the world's highest mountains. Environmental experts have created a new report that the current snow world as a whole has decreased by 10%. The result is a volume of water flowing into the oceans will be increasingly high-auto-raise sea.

Global warming, rising temperatures, melting snow world, and rising sea levels could eventually cause climate change. We now feel the coming of the dry season is longer than it should. As a result of ground water becomes scarce because it has not received a new supply of rain.

The Indonesian government does not want to be left to face the issue of global warming. The Indonesian government is finalizing the idea of establishment of the Forum Eight Countries that have the Tropical Rain Forest (Forestry Eight), as an effort to address global warming. Since September 22, 2007, President SBY has been in New York to attend a series of UN General Assembly and the UN general council. In the occasion, Yudhoyono will deliver a speech on global climate change. We hope that what is being discussed at this time can give good results that can be felt by the world community.
