Definition of global warming: Global warming is the observed and projected increases in the average temperature of Earth's atmosphere and oceans. The Earth's average temperature rose about 0.6° Celsius (1.1° Fahrenheit) in the 20th century Causes of global warming: Global Warming is caused by many things. The causes are split up into two groups, man-made (anthropogenic causes), and natural causes. Natural Causes: Natural causes are causes created by nature. One natural cause is a release of methane gas from arctic tundra and wetlands. Methane is a greenhouse gas. A greenhouse gas is a gas that traps heat in the earth's atmosphere. Another natural cause is that the earth goes through a cycle of climate change. This climate change usually lasts about 40,000 years. Man-made Causes: Man-made causes probably do the most damage. There are many man-made causes. Pollution is one of the biggest man-made problems. Pollution comes in many shapes and sizes. Burning fossil fuels is one thing that causes pollution. Fossil fuels are fuels made of organic matter such as coal, or oil. When fossil fuels are burned they give off a green house gas called CO2. Also mining coal and oil allows methane to escape. How does it escape? Methane is naturally in the ground. When coal or oil is mined you have to dig up the earth a little. When you dig up the fossil fuels you dig up the methane as well. Another major man-made cause of Global Warming is population. More people means more food, and more methods of transportation, right? That means more methane because there will be more burning of fossil fuels, and more agriculture. Now your probably thinking, "Wait a minute, you said agriculture is going to be damaged by Global Warming, but now you're saying agriculture is going to help cause Global Warming?" Well, have you ever been in a barn filled with animals and you smell something terrible? You're smelling methane. Another source of methane is manure. Because more food is needed we have to raise food. Animals like cows are a source of food which means more manure and methane. Another problem with the increasing population is transportation. More people means more cars, and more cars means more pollution. Also, many people have more than one car. Since CO2 contributes to global warming, the increase in population makes the problem worse because we breathe out CO2. Also, the trees that convert our CO2 to oxygen are being demolished because we're using the land that we cut the trees down from as property for our homes and buildings. We are not replacing the trees (an important part of our eco system), so we are constantly taking advantage of our natural resources and giving nothing back in return. Effects(consequences) of global warming: There are two major effects of global warming:
More details about the effects of global warming : Increasing global temperatures are causing a broad range of changes. Sea levels are rising due to thermal expansion of the ocean, in addition to melting of land ice. Amounts and patterns of precipitation are changing. The total annual power of hurricanes has already increased markedly since 1975 because their average intensity and average duration have increased (in addition, there has been a high correlation of hurricane power with tropical sea-surface temperature). Changes in temperature and precipitation patterns increase the frequency, duration, and intensity of other extreme weather events, such as floods, droughts, heat waves, and tornadoes. Other effects of global warming include higher or lower agricultural yields, further glacial retreat, reduced summer stream flows, species extinctions. As a further effect of global warming, diseases like malaria are returning into areas where they have been extinguished earlier. Although global warming is affecting the number and magnitude of these events, it is difficult to connect specific events to global warming. Although most studies focus on the period up to 2100, warming is expected to continue past then because carbon dioxide (chemical symbol CO2) has an estimated atmospheric lifetime of 50 to 200 years. Solutions:here some individual behaviours with your car to contribute reducing this phenomena : · Go Green: Use alternative fuel vehicles and learn about alternative fuels. Or second best, check out the fuel economy and emission information on any vehicle you own, or are planning to own. Start with the Green Vehicle Guide and the Fuel Economy Guide to see how your four wheels shape up. Check if you have a flex-fuel vehicle (FFV)—with over 5 million FFVs on the road today—your car might just be a FFV sleeper. · Go Easy & Maintain, Maintain, Maintain: A variety of factors affect your vehicle’s fuel economy—and one of the most important is an easy driving style and regular maintenance. If you use a lighter foot on the brakes and gas pedal, avoid putting the pedal to the m-e-t-a-l for fast accelerations, and reduce idling time, your fuel economy will improve—and decrease greenhouse gas emissions. Checking and inflating those tires to the correct pressure will also help. ·Buddy up: Whether you choose to carpool with friends, grab the bus, hop on your bike or locomote with your two legs, they’re all ways to leave your car parked in the garage—and reduce your contribution to the carbon burden. Parking your car and choosing one of these alternatives just two times per week can chop greenhouse gas emissions by about 1,590 pounds per year. Good news, huh? And good for you—who couldn’t use more exercise? · Plan first: When heading out to take care of errands, see if you can combine trips. Those short trips when your car's engine is cold can use twice as much fuel in addition ps: i could not make sure that those infos are completely acceptable but i did my best ......peace |
