Global Warming Question

1. Grobal warming is a long-term climatic change which raise the temperate of the atmosphere and oceans in recent decades.
2. Grobal warming is caused by a layer of greenhouse gases built up in the atmosphere. The more the greenhouse gases emitted, the more heat will be trapped around the Earth. Human activities (combustion of fossile fuels, deforestation, industry, agriculture, landfill sites, use of refrigerants and solvents) are responsible for the increase in greenhouse gases.
3. Use fewer plastic utensils, foam cups and containers, use engrgy-efficient appliances, e.g. fluorescent lamps, plant trees or small plants at home, in schools and offices to absorb carbon dioxide, use less packaging products, use mosquito net instead of insect repellent, etc.

1. Global warming is the observed increase in the average temperature of the Earth's atmosphere and oceans in recent decades.

2. The increased amounts of carbon dioxide (CO2) and other greenhouse gases (GHGs) are the primary causes.

3. we must try to reduce the emissions of CO2 into the atmosphere, by using other alternatives to fuels like solar power and wind power, and drive less, but so far alternatives are not efficient in providing the power we need for everyday life.

there is a good new documentary with al gore talking all about the effects of global warming, go have a look at it if u have time, its called "An Inconvenient Truth"
