Australia's natural wonder is Great Barrier Reef. The Great Barrier Reef is as big as the total combined area of the UK and Ireland. But tourist's thoughtless to destruct of Coral Reef for souvenir. One clear message form the case is that dryland salinity and water scarcity have arisen in Australia. As water scarcity is worsened by climate variability, Australia places a very high priority on cooperative action on climate change and related issues in the Pacific region.

Describe the processes responsible for ice movements. (20)Explain what factors influence the rate of glacier ice movement. (25)
thus increasing the rate of ice deformation around the obstacle, allowing the ice mass to smoothly pass over or around the object. (which can form a roche moutonee) Another process that controls the flow of a glacier is a process called sub glacial bed deformation. This is where lose sediment at the bed of the glacier moves enabling the glacier to move more freely over the bed. In order to do this the subglacial bed has to be a warm based glacier, i.e.

Our atmosphere is like a blanket, as pollution is released by power plants, automobiles, and others the blanket thickens trapping heat more easily. Over the past 50 years the average global temperature has been increaseing at an overly fast pace, Scientist agree unless we compensahate for our polution the U.S. will be faced with a 3-9 degree higher temperature by the end of the century. Effects of Global Warming: There is a range of harmful effects that come from Global warming such as rising sea levels, flooding coastal areas, higher percentage of heat waves and more intense, droughts and wildfires occure more often, disease, and possible extinction of species that cannot accommodate to these changes.

Wendy's vision is to be the quality leader in everything they do. REMOTE ENVIRONMENT Wendy's did show a lot of new ideas as far as the remote environment was concerned, for instance it established stored abroad, in the national expansion the franchisee agreement was for the area, a region and not for a store. Here she made agreements for time, area, technical associations and royalty. There are different problems that she has faced like inflation, energy problems, increasing labor cost and increasing beef price.

'What are: ozone depletion potentials (ODP) and how have they helped in understanding the current global situation on atmospheric ozone?'
has been formulated to help us gauge the effect of synthetic chemicals on depleting stratospheric ozone (Parker,1996). This work will discuss what ODPs are and what they have done to halt ozone depletion. ODP is a number gauged by a mathematical calculation (Appendix 1A) (Person,1997), given to a substance that refers to the amount of ozone destruction it can cause, over its entire lifetime relative to that of a 'referenced substance' which is CFC-11. So for example CFC-115 has an ODP of 0.6 (Appendix 2A) (EPA,2004), which destroys 3/5 as much ozone as CFC-11. ODP is often used in conjunction with Chlorine Loading Potential (CLP)

Natural Hazards - This report will look at the floods that occurred along the Yangtze River, and Dongting lake, China, August 2002. Floods are very common within China's provinces.
Although there were no floods along the major rivers, there were flash floods, landslides and mudflows, which resulted in high casualties. This report will be a factual account of what hapend in these provinces. River and coastal flooding are the most frequently occurring natural disaster and are increasing in occurrence more rapidly than any other disaster. Urbanization and deforestation reduce the capability of the earth to hold excess water. As asphalt expands and open spaces disappear, it takes less rain to flood communities as water running over the pavement collects quickly and easily disrupts storm drain systems.

A floodplain is a mostly flat area of land bordering a river that is subjected to periodic flooding. It is made up of silts and sands, which have been deposited over many years by the river. Whilst some deposition takes place within the river channel, the bulk of the sediment is deposited when the river floods. The reason for this is that as the river spreads over its floodplain, there is a sudden increase in both the wetted perimeter and the hydraulic radius.

The two tickets are only valid in one day that means if you want to visit it again the next day, you have to pay the tickets again. After we entered the main gate, a working personnel came and showed us to the bus station. This kind of bus is said to better solve the problem of pollution of tail gas to the environment of the scenic spot. Soon the bus started and a lovely Tibetan girl, served as a guide, began to introduce Jiuzhaigou to the passengers.

With reference to one or more examples, describe how and why strategies of river basin management are different between LEDCs and MEDCs?
The River Colorado, which is 1470 miles long, is the most managed river of its size in the world. Eighteen dams lie along the river, which have the significant effect of reducing the water flow downstream and reducing peak discharge, thus reducing the flood risk. On the other hand, the intensity of river basin management in Bangladesh for the Ganges-Brahamaputra is significantly less. The only permanent form of flood management is the 3500 km long embankment that was completed as part of the 1987 Flood Action Plan drawn up and financially supported by the World Bank. Furthermore, even greater differences lie in the usage of these schemes.

"Atmospheric hazards are natural phenomena." A Natural Hazard is an unexpected or uncontrollable natural event of unusual magnitude
Even though humans cannot be the sole cause of an atmospheric event, their influence can have an effect on the frequency, magnitude and also the location of atmospheric hazards. Atmospheric events can be labelled as a hazard when people or infrastructures are at risk. However, sometimes an atmospheric event would not become a hazard in the first place, if it wasn't for human developments interfering with natural processes. In ancient times, people didn't have the technology we have today, and learned how to live with atmospheric events. The flooding of the river nile, was actually beneficial to the ancient Egyptions.

News has been said that the global climate has been warming for the past number of years. The gases that contribute to the greenhouse effect are called "greenhouse gases and include water vapour, carbon dioxide (CO2), methane, nitrous oxide, chlorofluorocarbons (CFCs) and ozone. Of these, the most prevalent human-produced gas is carbon dioxide, whose source is primarily the burning of fossil fuels" (Richard C. Rhodes) such as from vehicles and factories. Air-condition and refrigerator is widely used nowadays as this produce CFCs that will harm the world's ozone.

This is simply a natural flow on. A good communication climate has been shown to enhance a business or organisation on many fronts Where does it come from? Just as the rain pours from above, so does the communication climate.

What is an actuarially fair insurance premium? How might adverse selection and moral hazard lead to inefficiency in insurance markets? What actions may insurance companies take to reduce these problems?
For example if probability of a suit is 1/5 then you can buy $1 worth of insurance for $.20. Below is the Budget constraint with actuarially fair insurance, were the slope of the budget constraint is = p/(1-p) In the diagram above where A is the endowment point and B the preferred consumption, insurance is actuarially fair. Equilibrium occurs where Cs= Cn. By making this expenditure on insurance, risk is eliminated. In the event of a lawsuit or no lawsuit her consumption is the same- she is fully insured.

This report is for the United Nations Officals, it will give an overview of the causes of flooding in Bangladesh and the impacts these floods have on the environment and people.
Strategically located Bangladesh is virtually a bridge between south and southeast Asia. It has a landmass of 1,48,393 sq. km criss-crossed by a network of several major rivers, their numerous tributaries and canals forming a lace of interconnecting channels. In fact, Bangladesh is the largest riverine delta in the world. The Climate The average annual rainfall varies from a maximum of 5,690 mm in the northeast of the country to a minimum of 1,110 mm in the west. The groundwater, however, provides adequate storage to compensate for annual variations in rainfall and streamflow.

"What may cause sea levels to rise? How might rising sea levels pose significant problems for human populations? How might these negative effects be addressed?
Ideas as to a possible sea-level rise are estimated at "up to 100 centimetres over the next 100 years". The Pew Centre on Global Climate Change ('PCGCC') have stated that sea levels have risen 25 centimetres in the last 100 years and they say they will rise another 50 centimetres in the next 100 years. The effects on coasts if sea levels were to rise are mass erosion of beaches; major flooding in low areas and loss of wetlands. More than 50% of the United States population live on or near the coast and are considered vulnerable to rising sea levels; the 'PCGCC' have believe the effect could be worsened if it were to be accompanied by storm activity.

Make a comparative study of the PPT between the tropical monsoon and cool temperate western maritime types of climate.
The activity of this climate can be split into three seasons. March to May, June to September and October to February. In the march to may season it is very hot and dry. In the June to September season the rain hits and 80% of the annual PPT falls in this time. It is patterns of pulses of very heavy rainfall. Temperatures drop by a few degrees. Finally in the October to February season the wet season ends and there are generally clear skies with mild temperatures.

The north and west may get even wetter and there could be more storms and floods. * Many animals and plants may not be able to cope with the rising temperature and may move north as it will be cooler there than in the south. There might not be room for all of them so some might not survive. Global warming would damage wildlife ecosystems as they are being forced to migrate away from their homes. * Due to the rising sea level the Thames barrier could collapse due to a direct implication of the sea level continuing to rise.

The climate for a region depends mainly on the yearly cycle of its temperature and moisture; this can dramatically change a region's climate. There are many other factors that play roles in climate depending on where the location is. Such as wind direction, seasonal humidity, location with respect to oceans and mountains, and cyclone activity. Even though there are so many factors to consider with climate, climate very slowly changes over time.

Dr Andy Baker of Newcastle University said, 'our research suggests that British rainfall is naturally highly variable... We have shown that nature is able to repeat current events without the help of global warming. Effects There was degradation in the road and rail infrastructure. Hospitals were evacuated because of the risk of disease and illness. Bridges across rivers were opened and closed erratically as the water level fluctuated. Homeowners hit by floods saw premiums rise by up to 60%, as brokers tried to claw back the costs of claims topping �200m. The Insurance companies were contemplating refusing insurance to those homes repeatedly hit by flood plains.

> Silt, deposited at the mouth of the Ganges and Brahmaputra, has formed a large delta. This eventually created many flat islands. They attracted large numbers of farmers for rice growing. Further deposition of silt blocks the main channels and increases the flood risk by raising the beds of the rivers. Flooding is most likely to occur in late summer following the seasonal monsoon rains. > Water is pushed northwards by tropical cyclones up the Bay of Bengal. Silt deposits cause the Bay of Bengal to become narrower and the sea shallower.
