Physical Geography DE The Worst of Global Warming in Australia has begun Global warming is a reality we are facing all too suddenly. The affects of our destruction were apparent but seamlessly life in this world carried on. We are now concerned with the affects of global warming after some seen destruction in this world. We’re having problems such as polar ice caps melting, burning of fossil fuels and such. Australia has ignored for much time the affects of global warming. They are now suffering for this negligence. Earth’s climate is in harmony by a natural greenhouse effect. This is created by our atmosphere which captures green house gases such as methane and carbon dioxide. Humans have destroyed the atmosphere so much that effects are changing life as we know it. Humans have contributed to these green house effects by burning of fossil fuels. These fossil fuels are things such as coal and oil. We depend on combustion of fossil fuel for energy. All this is creating an extra blanket of unnatural gases around the world. An increase in problems in Australia is devastating the natural habitat of the environment. Australia is suffering from extreme drought and many bush fires that was devastates the terrain exponentially. The temperature has risen in Australia in less than 100 years about 0.7 degrees Celsius. Animals and plants are suffered also with these effects. A recent study showed that 1/3 of the population of wildlife suffering is on the endangered species list. Many of these animals simply cannot survive due to a long term climate change. Animals like Koalas are at risk by the changes that increased CO2 may have on the quality of food plants. Plants that have root and stems and other plant materials are at risk of losing its nutrients from reduced nitrogen content. Hotter temperatures and drier conditions projected for the south of Australia will see an increase in the intensity of forest fires (IPCCb, 2001; Williams et al., 2001). The consequences of global warming for Australia are going to be devastating. Australia is getting 80 percent of its energy from burning of fossil fuels. These actions have lead to a rise in average temperature. Habitats are disappearing as bush fires take out all the natural areas of Australia. The drought has gotten worse. Many agriculture areas have been shut down or are at the brink of shutting down. Lack of water means there will not be any crops. The food shortage in Australia is slowly increasing. Australia can find many ways to change its situation around. It will take a few years but it must be done. Australia uses 80 percent of its energy through the burning of fossil fuels. Using renewable fuels for their energy use could provide the same results, but just with a better end cost. They can move there coal-fired power stations away from centralized area. This will require a big expense but the after effects are worth it. There are also jobs available in sustainable energy. This would help the Australian economy. Also they would get independence from oil price changes. A lot of the rural parts in Australia are dependent on imported fuels. Working with bio-diesel can greatly reduced the pollutants that affect their agriculture and water. Australia has a long way to go. But the effects of global warming will last longer if they do not change their ways soon. Humans in nature are destructive. When we throw waste it only affects us later. This is our mentality that we need to change. We cannot do something at the time it affects us, we must act now to prevent further damage. Work Cited Australian Greenhouse Office (2001).
