Although Australia is a large country, and the population is heavily urbanised, the urban centers of Melbourne, Sydney, and Canberra are relatively close to the mountains and therefore relatively close to developed ski fields (Figure 1). In a recent report written by the Commonwealth Scientific and Industrial Research Organisation (CSIRO), which is the Australian Government's national scientific and research organisation, simulations indicate that the total alpine area with an average of at least one day of snow cover will decrease between 10-39% by 2020, and 22-85% by 2050 with average season lengths reduced by at least 5 days. While global warming might on the surface present a problem to the tourism industry in the Australian Alps, it does provide new opportunities for non-snow based tourism and recreation throughout the year. The following symbol (Figure 3) on the map represents a cold front where a cell of cold air from the polar regions sweeps up towards southern Australia. Step 6: Note that you may find that there are a number of placemarks indicating the location for Mount Kosciuszko that people have added to Google Earth (see Figure 9).
However the highest point (a track leads up to this point) is indicated as an elevation counter in the browser window at the center bottom of the screen. If you have ever hiked up a mountain, you've probably noticed that the air becomes cooler the higher you go. If you are using this module in collaboration with a class in a different country, your instructor may now assign you an activity, Australia Case Study - Group Activity 2, in which you will share your polygons in a collaborative analysis. Look at the time series graph for Australian mean temperature anomalies adopting 1961-90 as the baseline (Figure 12).  What is the direction of the trend? Under the list of mean temperatures for each month are listed a series of positive and negative numbers ranging from between -3 and +3. We are now going to create a trend line of the annual anomalies, so that we can predict into the future an estimate of the annual anomalies.
You have just created a trend line of anomalies for annual temperatures for south eastern Victoria near Mt Buffalo. Given that for X = 0 (year 0 or 1950) the annual anomaly is approximately -0.2oC and for X = 58 (year 1950 + 58 or 2008) the annual anomaly is +0.2oC, what is the annual anomaly for the years 1975 and 2000? Given that the general equation of a straight line is y = mx + C where m = the gradient of the line, what is the gradient of the trend line? Using an environmental lapse rate of 6.4oC, what in terms of elevation, does an increase of 1oC equate to in elevation?


Using an environmental lapse rate of 6.4oC, what in terms of elevation, does an increase of 3oC equate to in elevation?
What will be the new snowline elevations under these two scenarios (estimate to the nearest 10 metres)? Given a 3oC temperature increase, when will the two ski areas become economically compromised? ATMOSPHERIC PRESSURE IS THE FORCE PER UNIT AREA EXERTED AGAINST A SURFACE BY THE WEIGHT OF AIR ABOVE THAT SURFACE IN THE EARTH’S ATMOSPHERE.
This summary of the relative effects by the year 2100 is a composite derived from calculations carried out for 12 individual terrestrial and freshwater ecosystems by O.
The climate changes in the world have caused a huge impact in the agricultural sector of the economy. The climatic changes and a steady increase in the temperature at a global level have created a huge impact on the rainfall and general weather conditions in almost all parts of the world. The region of Western Samoa experiences dry season between April and October when the climate is cool. There are various aspects of food security which are affected by the climatic changes across the world. However, during the Australian winter the snow fields in New South Wales (NSW) and Victoria draw large numbers of skiers and snowboarders to the Australian Alps. The ski industry contributes around $268 million in Victoria and $300 million (Australian dollars) in NSW to the local and national economy (Pickering et al 2004). However, it is possible for season lengths to decrease up to 30 to 40 days under worst case scenarios (Hennessy et al 2003). Given that Mt Buffalo is at a similar latitude to that of Mt Hotham we can assume that the approximate current snowline for Mt Buffalo is also around 1420 metres.
Calculate, using an average environmental lapse rate of 6.4oC per 1000 metres (Christopherson 2007), what the mean monthly temperatures of Mt Buffalo are likely to be. IN MOST CIRCUMSTANCES ATMOSPHERIC PRESSURE IS CLOSELY APPROXIMATED BY THE HYDROSTATIC PRESSURE CAUSED BY THE WEIGHT OF AIR ABOVE THE MEASUREMENT POINT.


Man made intervention into the existing natural flora and faunal communities has resulted in drastic changes in the ecosystem. Climatic changes, stress on the ecosystem, imbalance of the equilibrium in nature, extreme and unpredictable weather conditions are among the main factors which cause this undesired effect in the world today. The disturbances in the balance of agro-ecological conditions indirectly affect the economy.
These changes hamper the overall quality of life and natural settings in the tourist spots.
Most of the alpine resorts are at altitudes of between 1400 and 2000 meters, and the impact of global warming on the Australia ski industry has been found to be significant. In surveys of people visiting ski resorts, König (1998) found that the majority of visitors would either give up skiing, ski overseas or ski in Australia less often should snow cover decline. What is the approximate latitude and longitude of the highest point on Mt Buffalo located at "The Horn"? LOW-PRESSURE AREAS HAVE LESS ATMOSPHERIC MASS ABOVE THEIR LOCATION, WHEREAS HIGH-PRESSURE AREAS HAVE MORE ATMOSPHERIC MASS ABOVE THEIR LOCATION.
This case study will enable you to look at actual climate data and estimate the spatial impact of global warming on one particular resort in Victoria. LIKEWISE, AS ELEVATION INCREASES, THERE IS LESS OVERLYING ATMOSPHERIC MASS, SO THAT PRESSURE DECREASES WITH INCREASING ELEVATION. Overall, changes in land use constitute the main estimated impact on biodiversity, but the pattern varies considerably for different ecosystems.
