Deforestation contributes to global warming by emitting greenhouse gases. We can reduce climate change hazards by refusing to deforest and restoring forests.
The impact of greenhouse gases on global warming 气候变化是当今世界不可避免的话题。近年来,全球气温上升以及天气更加极端成为人们关注的焦点,引起了对于人类活动对环境的影响的重视和警惕。科学家们认为,导致这些问题的主因是温室气体的排放量不断增加,造成了全球变暖。那么,温室气体到底是什么,以及它们对全球变暖...
Some atmospheric gases (water vapor, carbon dioxide, and other gases) trap some of the outgoing energy, retaining heat somewhat like the glass panels of a greenhouse; These gases are therefore known as greenhouse gases; The greenhouse effect is the rise in temperature on Earth as certain gases ...
(过滤)it,so people,plants,and animals would be exposed to all the light and heat.Although the greenhouse effect makes the Earth able to have people living on it,if theregets to be too many gases,the Earth can get unusually warmer,and many plants,animals andpeople will die.Plants would ...
The next century, however, may see unusually rapid changes because humanity is adding gases that absorb infrared radiation to our planet's atmosphere, and thereby enhancing the "greenhouse effect." This entry examines the greenhouse effect, the trends in climate, and expected future changes. ...

The global warming greenhouse effect occurs when excess gases, known as greenhouse gases, become trapped in the Earth's lower atmosphere, preventing heat from escaping into space. The greenhouse gases allow light to come in, but stop heat from escaping, similar to the design of a greenhouse. ...
