GreenHouse温室效应介绍及其危害英文

greenhouse gas:
• Carbon dioxide is not the only greenhouse gas.
• Other gases, such as methane (CH4) and nitrous (氮的、硝的 ）oxide (NO), are even stronger infrared （红外线的） absorbers.

Population growth
Global warming is when the earth heats
up(the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature.
Greenhouses allow for greater control over the growing environment of plants. Depending upon the technical specification of a greenhouse, key factors which may be controlled include temperature, levels of light and shade, irrigation, fertilizer application, and atmospheric humidity.
What is greenhouse?
A greenhouse (also called a glasshouse) is a building in which plants are grown.
A greenhouse is a structural building with different types of covering materials, such as a glass or plastic roof and frequently glass or plastic walls; it heats up because incoming visible solar radiation from the sun is absorbed by plants, soil, and other things inside the building. Air warmed by the heat from hot interior surfaces is retained in the building by the roof and wall.
Transportation Gasoline for automobile engines raises the level of carbon dioxide in the atmosphere.
Many factories produce longlasting industrial gases, which contributes significantly to the enhanced greenhouse effect and "global warming" that is currently under way.
What is Man-made greenhouse effect?
How Do We Human Beings Contribute to the Greenhouse
Effect? Where Do We Release Greenhouse Gases?
Burning natural gas and coal in daily life.
Definition:
The so-called greenhouse effect is short-wave solar radiation through the atmosphere into the ground, and warming the ground after the length of radiation being released in the atmosphere by absorbing carbon dioxide and other substances, thereby creating the effect of atmospheric warming, just like the greenhouse’s effect on plants.
If the Earth had no greenhouse effect, its average surface temperature would be very low of about -18°C rather than the comfortable 15°C found today. The natural greenhouse effect is essential for maintaining the proper temperature needed to sustain life on Earth.
Sea Level Rise
• By the year 2100 (and some as soon as 2030), would flood 15 percent of Egypt（埃及）, and 12 percent of Bangladesh(孟加 拉国). The Maldives (马尔代夫 ）in the Indian Ocean would almost completely disappear.
