The Efficiency of Outroad Transport

	 The Efficiency of Outroad Transport
Global warming is the warming up in the earth?s climate. The earth has warmed up about 1 degree over the last 100 years, scientists aren?t sure if the earth is just warming up on its own or weather its down to people helping the process along with the things we do. The main cause of global warming is the increasing use of fossil fuels. Since the industrial revolution people have needed more energy for work and in the home, this has come from the burning of fossil fuels more fossil fuels, particularly coal and oil. This is also down to them being burnt and releasing more carbon dioxide and methane into the atmosphere which cause what?s known as The green house effect. Information on how the greenhouse affect effects the earth.Global warming causes the sea levels to rise. This is caused by the ice sheets and glaciers are being melted. Sea levels have risen by 0.25 metres in the last 100 years, in the next 100 years the sea levels will probably rise by another 0.5 metres. There are many low lying areas of the world, like the south-east England and others in trouble due to flooding. The world?s climates are changing as well, there are more draughts, floods, and storms could become more severe, widespread and common. Examples of this could be that the Sahara could spread north into the south of Europe, also the north Atlantic drift could be altered and Britain could become a lot colder. What greenhouse gases are Greenhouse gases are chemical compounds found in the Earth?s atmosphere. These gases allow sunlight to enter the atmosphere freely. When sunlight strikes the Earth?s surface, some of it is reflected back towards space as heat. Here is a graph of the rise in temperature of the world and the rising sea levels. [image] [image] The main causes of greenhouse gases The main ways to reduce greenhouse gases is to become more efficient in burning fossil fuels, reducing emissions from cars is a huge factor as most adults in the world will have a car, and the amount of cars is growing every day just as the amount of people in the world is growing. The ways to reduce greenhouse gases Driving a car or using electricity is not wrong. We just have to be smart about it. Some people use less energy by carpooling. For example, four people can ride together in one car instead of driving four cars to work. Save Electricity . Whenever we use electricity; we help put greenhouse gases into the air. By turning off lights, the television, and the computer when you are through with them, you can help a lot. Bike, Bus, and Walk. You can save energy by sometimes taking the bus, riding a bike, or walking. Plant Trees, Planting trees is fun and a great way to reduce greenhouse gases. Trees absorb carbon dioxide, a greenhouse gas, from the air. Recycle cans, bottles, plastic bags, and newspapers. When you recycle, you send less trash to the landfill and you help save natural resources, like trees, oil, and elements such as aluminium. Here is a graph of what gases make up greenhouse effect. [image] Here are some things that global warming has caused There are many problems that are caused by global warming and the greenhouse effect. Several signs indicate that we?ve begun changing Earth?s climate: increased water vapour in the atmosphere, glaciers and polar ice caps appear to be melting, floods and droughts are becoming more severe, and sea levels have risen, on average, between 4 and 10 inches since 1990. People have said that we might get a 2 foot sea level rise, but the catch is levels might continue to rise 2 or 3 feet per century, for 1000 years. These rises can increase sea levels and cause coastal lands to be washed under the ocean. Warmer water and increased humidity may encourage tropical cyclones, and changing wave patterns could produce more tidal waves and strong beach erosion on the coasts.

Method and results: On Wednesday the 11th of May 2005, the whole of 10H went to do a survey on the amount of people in cars going to and away from Sutton to see if a lot people drove cars and only had one person per car or if there was more than one. My hypothesis was that there would mainly be 1-3 people in one car at any time; any more would be highly unlikely except for parents on the school run towards our school or Overton Grange. Our methods were for two groups to tally the amount of people in cars going to and from Sutton. We did this by doing two separate ways of collecting our data, the first one was to wait outside the Sutton car park and record the amount of people in the car, whether they were coming or going to Sutton, and the last piece of data was work vehicle they were driving. The other method was to stand on the pavement of the main road into Sutton and record the same things we did at the car park, also we recorded which time the data was recorded.

It also gives a total amount of how many people we saw in each car from 1-5 and how many other vehicles we saw go by.

It was to find out how the people in our school get to school, we went around all of our classes and asked them 2 tell us where they travel from and how they travel. We all predicted that most people would live within 3 miles and travel by car. Here are the people who travelled by car.

Walk Carshalton 2 Sutton 2 Total 4 Analysis: Table 1: The first table is showing you that there is a fairly steady flow of people in cars, to and from Sutton, the busiest time is between 8.00 A.M and 8.30 A.M, the quietist time in the day is 10.00 A.M till 10.30 A.M. This table also shows you the huge amount of people by themselves travelling in a car, and if some of these people were to group travel, possibly to and from work it could make a big difference if enough people do it. There was a average to small amount of people travelling with 2 people in there car, after that there aren?t many people at all travelling with 3 or more people in their cars there is a total of 225 people travelling with 3 or more people in a car out of 3723 cars, that is a very small percentage of under 10%. There wasn?t many people travelling by motorbike or push bike, and when they did travel that way it was in the morning probably going to work on the train and living between 1 and 2 miles away. There weren?t many buses or lorries going to and from Sutton, there was only one other form of transport that did go to and from Sutton and that was van, there were a total of 476 lorries travelling to and from Sutton. Table 2: In table 2 it shows you our results that we collected from outside the main car park at Sutton station. We recorded the amount of people in vehicles and what form of travel that their using. They are a huge percentage of people travelling by themselves in a car; this table follows the same as table 1, all of our results follow the same pattern as in the 2nd table. Table 3: In table 3 it?s showing the data we collected around our school on how they travel to school. We asked 105 people and 46% of the people travelled to school by car, 36% of people took the bus, 16% take the train and y 4% of the students at my school walk. Conclusion: Having collected and analysed all of the data I believe that there is far to many people travelling by themselves in cars or not travelling very far, instead of getting public transport or riding a bike or walking a mile, people would rather take there car, and if we don?t start either grouping our travel when possible or taking public transport we could damage the earth so much that it cant be reversed, but while were giving all these emissions out the world will go on suffering and continue to increase the amount of global warming.
