Scientists say the warming of the Earth’s atmosphere has begun to affect plant and animal life a round the world. Scientists from the University of Hanover in Germany reported their findings in Nature. They say global warming is affecting endangered species, sea life, and the change in ...
Greenhouse gases, such as carbon dioxide,are produced by factories, power stations and vehicles. 如二氧化碳等的温室气体是由工厂、发电站及车辆排放所导致。 They trap heat in the Earth's atmosphere. 这些气体能阻止大气层散热。 Research shows the level of carbon dioxide gas in the Earth's atmosphere...
Without this process, Earth couldn't sustain life. However, the“man-made" greenhouse effect has now become a big problem.When people produce huge amounts of extr a greenhouse gases 5 by burning fossil fuels, more heat is trapped in the atmosphere and causes Earth's surface temperature to ...

The Earth has warmed up before, but this was the result of things like wobbles in the Earth's orbit, not because of an increase of greenhouse gases in the atmosphere. Neil Can we reverse the changes? Alice No, it's too late, and now...
Global warming, the gradual heating of Earth's surface, oceans and atmosphere, is caused by human activity, I ( primary) the burning of fossil fuels that release carbon dioxide and other greenhouse gases into the atmosphere. One of the most immediate and obvious 2(consequence) of global warmin...
The earth’s temperature is rapidly changing. As a result there has been a lot of climate change such as heat waves, droughts and floods. Scientists believe that this is the result of human activity, which is polluting the Earth’s atmosphere. This could become a disaster if governments do...
As evidence that the Earth’s atmosphere is warming continues to accumulate, scientists are making slow progress toward an answer to the big question raised by the evidence: How much of the warming is due to human activity and how much to natural causes 相关知识点: 试题来源: 解析 地球大...
4. When people produce huge amounts of extra greenhouse gases by burning fossil fuels more heat energy is trapped in the atmosphere and causes Earth’s surface temperature to rise quickly. (P27) 5. There is strong and comprehensive...
The Earth's atmosphere acts like a protective blanket around us. This blanket allows the energy from the sun to penetrate, so the sun warms the Earth, and then the atmosphere benighly slows the rate at which that warmth radiates out. Collectively we humans have a baby: the Earth. Year ...
