Does Global Warming exist?

Does Global Warming exist? Evidence For: Evidence Against: * Methane Increasing Levels of atmospheric methane, a powerful greenhouse gas, have risen 145% in the last 100 years. Methane is derived from sources such as rice paddies, bovine flatulence, bacteria in bogs and fossil fuel production. * Peculiar Weather Recently, young people in Vietnam noticed strange white stuff covering the fields. They had never seen snow before. It is the coldest spell in the country for 20 years. * Carbon Dioxide Increasing in Atmosphere The atmospheric levels of the greenhouse gas carbon dioxide, have increased since pre-industrial times from 280 part per million (ppm) to 360 ppm, a 30% increase. Carbon dioxide concentrations in the atmosphere are the highest in 160,000 years. Carbon dioxide is a by-product of the burning of fossil fuels, such as gasoline in an automobile or coal in a power plant generating electricity. * Cooling Poles Recently, scientists found that temperatures in the Arctic have been cooling since the 1920s. Computer predictions are that, if the world is warming, the Poles should warm twice as much. * Disappearing Glaciers Ice is melting all over the planet. Glaciers are melting on six continents. If present warming trends continue, all glaciers in Glacier National Park could be gone by 2030. The park's Grinnell Glacier is already 90% gone. - Ice cores taken

A man called M.E.Mostyn M.P realised that an opportunity was available to turn Llandudno into seaside resort. This area had everything he needed for example low rainfall, high sunshine and ancient buildings. In 1843 he bought 955 acres Llandudno and about half of it was on the sea front. He became the owner and development controller for most of the towns. In 1854 there were 21 commissioners which set strict rules on what people can and cannot built. Saps, hydros and hotels were built on the land. In 1891 Llandudno boomed as tourist resort after the railway along the N.Wales coast was completed. This made the town to attract people from Liverpool,

Bangladesh Problems

Bangladesh Problems. Bangladesh is considered a third world country; the major crisis Bangladesh endures is poverty. Increasing at a rate of about 2.06% per year, the current population of Bangladesh is about 138 million. 35.6% of the population is below the poverty line (Coutsoukis). Steps are taken to diminish the number of citizens that are below the poverty line. For example, Bangladesh decreased its illiteracy level of females from 73.5% in 1995 (Data Profile) to 31.8% in 2003 (Coutsoukis). This means that more and more people are deciding to receive an education. The Bangladesh government and the Bangladesh Aid Group have taken seriously the idea that Bangladesh is the test case for development. In the late 1980s, it was possible to say, in the somewhat patronizing tone sometimes adopted by representatives of donor organizations, that Bangladesh had generally been a "good performer." Even in straitened times for the industrialized countries, Bangladesh remained a favored country for substantial commitments of new aid resources from a strikingly broad range of donors. Even with the greatest imaginable efficiency in planning and administration, resource-poor and overpopulated Bangladesh cannot achieve significant economic improvements on the basis of that level of assistance. In examining the economy of Bangladesh, wherever one turns the problems crowd in and threaten

Common types of coastal problems are: pollution, erosion, salt intrusion, flooding calamities, habitat degradation / loss of biodiversity.

Anne Milot Enviromental Geography Topic: Coastal Problems Common types of coastal problems are: pollution, erosion, salt intrusion, flooding calamities, habitat degradation / loss of biodiversity. Coastal erosion of rocky cliffs and sandy beaches results from the action of ocean waves and currents. This is especially severe during storms. In many parts of the world the loss of land due to coastal erosion represents a serious problem. The action of waves, however, does not extend to a great depth, and the sea tends to cut a flat platform, characteristic of marine erosion, into coastal rocks. Various measures can be taken to reduce the risk of flooding, especially in the settled parts of floodplains. One of the most effective methods of reducing damage has been to alter the size of floods themselves. By planting trees, controlling soil erosion, and preserving wetlands, people have helped to reduce the size of floods. Special channels have been constructed to divert floodwaters away from built-up areas. The construction of dams has also been a very successful means of controlling floods. Constructing dams, however, can also alter the processes that shape the floodplains farther downstream. Since most sediment carried by a river settles out in the reservoir behind a dam, the water flowing past a dam has very little sediment in it. Water poor in sediment will scour sediment

To what extent is traffic congestion happening in Hexham town centre and what should be done to reduce the problem?

To what extent is traffic congestion happening in Hexham town centre and what should be done to reduce the problem? INTRODUCTION For my course work i will look to explore the extent of the problem of congestion in Hexham. Also i will look to investigate what should be done to help reduce this problem. The things in which i will be looking into to examine the problems of congestion will be things such as counting the amount of cars in carparks and counting the amount of traffic on the roads for 10 minutes. i will also do a questionare and mapping traffic hazards. here are four possible solutions which i feel will help reduce the amount of traffic congestion in hexham : pedestrianise the market place, introduce a one way system through the town centre, create new parking areas nearer the town centre and introduce a park and ride scheme at the tyne green which will allow people to park there cars at the tyne green and then a bus will transport them to the town centre. Finally i propose that we leave things as they are. It is important to reduce congestion so that we can reduce the amount of pollution which will create an enviromental hazard which will lead to health problems. Also it will reduce the amount of traffic related road accidents and it will make the roads safer. Also i will be looking into the background information of heham. Hexham has old narrow roads, There

Huntingdon has grown and changed a great deal from how it was originally. It has grown out from the oldest part which I believe is Market Square. Huntingdon is mainly shops and offices in the CBD but there is a little Housing. Further out there is a lot more housing both expensive and cheaper and many industrial parks. The town is still growing as more and more housing is being built due to the easy one hour commute to London on the train and the good transport links North, South, East and West because of the A14 and A1. Overall the amount of restaurants and pubs has increased in the last 15 years as has the amount of offices and the amount of

Geography Pedestrian Survey

Data collection This chapter is about how I collected the data for my surveys, and why I collected it in the methods I used. The Pedestrian Survey For this survey, the whole class worked as a group. We started by being given a grided map of Halifax's Central Business District and a small area surrounding it. Our teacher kept a copy of this as the master map. Each square on the map could be identified like the one below. This made identification of points easy. On this map there were (number) points marked by dots (see above) in the Central Business District and beyond. These were then grouped together into groups of approximately seven. The class was then split into pairs, and each pair was then allocated one of the groups of dots. The reason for working in pairs is so that one person could time and one could count the people passing. It was also for safety reasons. Before we started the count, we worked out some rules or guidelines for the whole class to follow. These were to * To count all people that passed, including babies in prams. * To not count pets/ animals * To count everyone on ONE side of the road only, except in precinct locations where everyone in the precinct was counted. A time limit of 5 minutes per point was decided. Each pair then went to their separate points to start counting/ timing. My pair had 6 points to count, so for 3 points person A timed
