The causes are many of which the main culprit is the increase in the roundhouse gases that is produced by burning fossil fuel and deforestation, thus intensifying the greenhouse effect leading to global warming. The four main contributors of the greenhouse effect are water vapor, carbon dioxide, methane and ozone. The greenhouse effect is a process by which the greenhouse gases absorb thermal radiation; these are then irradiated in all directions. But when some of these radiations come back to the surface and lower atmosphere, it causes increase in the average surface temperature leading to global warming.

Mining for coal and oil releases methane in the atmosphere. More ever the leakage from natural gas fields and landfills are additional source of methane. Excessive cutting down of the trees is another factor causing global warming. When deforestation happens the efficiency by which carbon dioxide is stored and oxygen released by the green plants are decreased to a huge rate in turn causing increased concentration of carbon dioxide that leads to increased greenhouse effect.

The nitrous oxide from fertilizers, gases used for refrigeration and industrial processes are other factors that cannot be forgotten as the cause of Global Warming-Another source of methane is methane accelerate, a compound intonating large amounts of methane trapped in the crystal structure of ice. As methane escapes from the Arctic seabed, the rate of global warming will increase significantly-Ice caps and glaciers reflect sunlight, bouncing high temperature sun -rays back into space away from the Earth.

When these icecaps are removed the earth gets warmer as the dark oceans absorb much thermal radiation from the sun. Some regions may be wet with rain and some areas will suffer drought due to global warming. The climatic changes happen due to global warming. Seasonal changes are unpredictable unexpected thunderstorms might result s mentioned earlier-The burning of wood (should be reduced to a greater extent) releases oxidize carbon to the atmosphere whose presence in greater amount causes the elevation of temperature.

There is strong evidence that emissions of chloroforms ribbons (CIFS) were the major cause of the recent abnormal warming. Like carbon CUFF do not trap heat but in the presence of IV rays the chlorine gets detached from CUFF, drifts up into the stratosphere and these unattached chi lorries catalytically convert Ozone molecules into Oxygen molecules depleting the ozone layer. Effects of Global warming: Global Warming Effects on Mankind Among the direct effects on mankind of global warming are: Homeless refugees displaced by flooding, hurricanes and drought.

Increased hunger due to food shortages because of loss of bearable land Spread of diseases, such as malaria and lame disease, due to the migration of disease- carrying insects with warmer, wetter weather and more standing bodies of water in the northern hemisphere. Economic hardships caused by catastrophic conditions, such as those in the aftermath Of Hurricane Strain. War and conflicts over shrinking resources. Steps to reduce Global warming :

Burning fossil fuels such as natural gas, coal, oil and gasoline raises the level of carbon dioxide in the atmosphere, and carbon dioxide is a major contributor to the greenhouse effect and global warming . You can help to reduce the demand for fossil fuels, which in turn reduces global warming, by using energy more wisely. Here are 10 simple actions you can take to help reduce global warming. 1. Reduce, Reuse, Recycle Do your part to reduce waste by choosing reusable products instead of disposables. Buying products with minimal packaging (including the economy size when that makes sense for you) will help to reduce waste.

And whenever you can, recycle paper and plastic , newspaper, glass and aluminum cans. If there isn’t recycling at your workplace, school, or in your community, ask about starting one. By recycling half of your household waste, you can save 2,400 pounds of carbon dioxide annually. 2. Use Less Heat and Air Conditioning Adding insulation to your walls and attic, and installing weather striping or caulking around doors and windows can lower your heating costs more than 25 percent, by reducing the amount of energy you need to heat and cool your home.

Turn down the heat while you’re sleeping at night or away during the ay, and keep temperatures moderate at all times. Setting your thermostat just 2 degrees lower in winter and higher in summer could save about 2,000 pounds of carbon dioxide each year. 3. Change a light bulb Wherever practical, replace regular light bulbs with compact fluorescent light (CFML) bulbs. Replacing just one 60-watt incandescent light bulb with a CFML will save you $30 over the life of the bulb. CAPS also last 10 times longer than incandescent bulbs, use two-thirds less energy, and give off 70 percent less heat.

If every U. S. Family replaced one regular light bulb with a CAP, it would eliminate 90 billion pounds of greenhouse gases, the same as taking 7. 5 million cars off the road. 4. Drive less and drive smart Less driving means fewer emissions. Besides saving gasoline, walking and biking are great forms of exercise. Explore your community mass transit system, and check out options for carpooling to work or school. When you do drive, make sure your car is running efficiently.

Every gallon of gas you save not only helps your budget, it also keeps 20 pounds of carbon dioxide out of the atmosphere. 5. Buy Energy-Efficient Products When it’s time to buy a new car, choose one that offers good gas mileage. Home appliances now come in a range of energy-efficient models, and compact florescent bulbs are designed to provide more natural-looking light while using far less energy than standard light bulbs. Avoid products that come with excess packaging especially molded plastic and other packaging that can’t be recycled.

If you reduce your household garbage by 10 percent, you can save 1 ,200 pounds of carbon dioxide annually. 6. Use Less Hot Water Set your water heater at 120 degrees to save energy, and wrap it in an insulating blanket if it is more than 5 years old. Buy low-flow soreheads to eave hot water and about 350 pounds of carbon dioxide yearly. Wash your clothes in warm or cold water to reduce your use of hot water and the energy required to produce it. That change alone can save at least 500 pounds of carbon dioxide annually in most households.

Use the energy-saving settings on your dishwasher and let the dishes air-dry. 7. Use the “Off” Switch Save electricity and reduce global warming by turning off lights when you leave a room, and using only as much light as you need. And remember to turn off your television, video player, stereo and computer when you’re not sing them. It’s also a good idea to turn off the water when you’re not using it. While brushing your teeth, shampooing the dog or washing your car, turn off the water until you actually need it for rinsing.

You ‘II reduce your water bill and help to conserve a vital resource. 8. Plant a tree If you have the means to plant a tree, start digging. During photosynthesis, trees and other plants absorb carbon dioxide and give off oxygen. They are an integral part of the natural atmospheric exchange cycle here on Earth, but there are too few of them to fully counter the increases in carbon dioxide caused by automobile traffic, manufacturing and other human activities. A single tree will absorb approximately one ton Of carbon dioxide during its lifetime. 9.

Get a Report Card from Your utility Company Many utility companies provide free home energy audits to help consumers identify areas in their homes that may not be energy efficient. In addition, many utility companies offer rebate programs to help pay for the cost of energy-efficient upgrades. 10. Encourage Others to Conserve Share information about recycling and energy conservation with your friends, neighbors and co-workers, and take opportunities to encourage public officials to establish programs and policies that are good for the environment.
