关于全球变暖、天气异常的作文1

Ladies and gentlemen,

Good morning, I am Li Hua from Tianjin, China . It’s my great honor to be here to talk about the global warming problem and ways of dealing with it.

Lately , global warming is becoming a serious problem. Several factors contribute to it. First of all, a lot of greenhouse gas is produced by cars and factories; furthermore, the loss of forests is another cause of global warming.

Global warming will cause some harmful effects. Firstly, some islands will disappear because of the rise of sea level. Secondly, extreme weather results from global warming. When temperature rises, the production of crops will decrease. Besides, some animals and plants will disappear, thus destroying the ecosystem.

So we should protect the earth from greenhouse gases. We should plant trees and reduce the amount of carbon dioxide and other greenhouse gases. Hope our earth can become better and better.

That’s all. Thank you.

People around the world may feel that the climate has been getting steadily warmer and warmer in recent years. Places which used to be abundant in snowfall have frequently experienced snowfree winters. Drought lasts longer in some dry areas. People find that without air conditioners they could hardly work or fall asleep on hotter summer days.

The side effects of global warming are alarminS. A warmer global climate melts the ice caps, raising sea levels. What is more, it disturbs weather patterns, causing droughts, severe storms, hurricanes. People suffer a lot from disasters relevant to global warming.

To stop global warming we should make immediate and continual efforts. We hope the situation will soon change. Global warming catches and holds our concern, for it affects us and will affect our later generations. We cannot wait any longer. Do it. Do it right. Do it right now.

global warming and our life Global warming has quickly become one of the most heated issues. With the development of the economy, the emission of the green house gas, consisting of about 70% carbon dioxide, has been increased, attributing greatly to the global warming.

Global warming is the slow and steady increase in the temperature of earth and its atmosphere. The increase in the temperature of earth has caused many effects like the melting of ice in Polar Regions, increase in disease occurrences, drastic climatic changes and rise of the sea level.

As the effects of global warming is becoming more and more evident, many of us have started to realize that steps have to be taken to control Global warming, such as the usage of clean energy resources and the alternative of motor.

Dear fellow students,

It is reported that the average temperature within the Arctic Circle has risen by 2—3 degrees Celsius in the past ten years. At the Copenhagen Climate Summit 20xx all nations were required to reduce the greenhouse gas emission to save the earth. At the beginning of 20xx, extremely cold weather hit Asia, Europe, and North America, which is the evidence of global warming.

As is known to all, our environment has been worsening due to human activities. If we don’t take effective measures now, human beings will not be able to survive in the future. If we can save energy, recycle waste and plant more trees, we can make the earth a better place. So let’s take action from now on! let’s save the earth.

Dear editor,

The curtain went down on the Copenhagen climate summit, leaving the world concerned more about global warming once again.

As is well known, it is human activity that has contributed to this problem. The burning of fossil fuels like coal, natural gas and oil produces greenhouse gases. When huge quantities of extra carbon dioxide are put into the atmosphere, more heat energy tends to be trapped in it causing the global temperature to go up.

However, the attitudes of scientists towards this rise are completely different. On the one hand, it’s predicted that there may be a rise of several metres in the sea level, extreme climate change or the disappearance of species. On the other hand, it’s supposed that the rise will make plants grow quicker and produce more, thus encouraging a greater range of animals.

It seems that the topic is controversial and there is a long way to go.
