The Impact Of Climate Change In Australia And The Environment

Illustrating the actual and potential impacts of climate change this paper seeks to dramatize the impacts climate change could have on Australia’s national security if action to cut carbon emissions is not taken.

Rising sea level can be caused by a variety of factors and can have an effect or influence even more. Future changes in sea level may impact human populations around the world and many other aspects of life on Earth more than many initially thought. The U.S. coast of the Gulf of Mexico is on track to be one of the most impacted by further sea level rise and the outcome could be detrimental to the entire coastline.

Since 1880, records show that the sea level has bone up 8 inches. If it goes up six more inches, as the current studies indicate could happen within 20 years, South Florida’s flood control would be devastated. In South Florida, taxpayers are already paying the price for climate change as salt-water pushes through porous bedrock into coastal drinking-water supplies, and rivers and canals choked by heavy rains have a harder time draining into the ocean.

Besides the direct effect of sea level rise, coastal flooding may also be a more prevalent and severe issue. For example, “sea level rise of two feet, without any changes in storms, would more than triple the frequency of dangerous coastal flooding throughout most of the Northeast” (Horton 374). The higher seas would increase the initial level, so that the flooding level would be much greater, especially during hurricanes. Recent hurricanes have become a good example of how much damage can occur to both humans and animals. For example, much of the coastal infrastructure is in danger of damage, which can affect commerce and the public’s health and safety: “In New York State, two feet of sea level rise is estimated...To flood or render unusable 212 miles of road, 77 miles of rail, 3,647 acres of airport facilities, and 539 acres of runways” (Horton 379). This loss of infrastructure may occur in every coastal Northeast state, especially in the south. In these southern Northeast states, the land is flat, which makes them easier to inundate with water. In addition to infrastructure, transportation is also at risk, with much of the major highways (I-95) and trains (Amtrak) at risk of coastal damage (Horton 380). More affected by sea level rise, ecosystems near water may be permanently damaged in upcoming years, and according to Rob Deconto, a climate scientist at University of

Climate change was blamed for risen in temperature by half a degree, producing more vapor which results in heavy rainfall in 2010 in Brisbane. The Burnett River and Fitzroy River were exceedingly bad hit on 28th and 29th December 2010, when the stream level rose to more than eighteen meters. Author was discussed that flooding proceeded into January 2011, turning out to be more terrible in Brisbane and damages came around 2.38 billion AUS dollars. Flood again hit the area in 2013 (Davies 2013).

Around 65 million years ago, the climate in Australia was cooler and wetter than it is now, with great, shallow seas in central Australia due to it being joined to Antarctica allowing for sea-living creatures such as the Plesiosaurs and Iscthyosaurs. However, as Australia started to separate from Antarctica and began moving northward roughly 23 million years ago, the climate became warmer and drier with temperate rainforest started to form. These great lush forests fed and protected large numbers of animals that were dependent on it for food and shelter. Central parts of Australia that was once seas and rivers, soon gave way to sand dunes and arid conditions. As of this change, vegetation type also changed, with species that were more tolerant

Climate change creates significant impacts in the Australian context: in considering sea level rise is one of the most critical condition and as per the IPCC report, in 2100 it will increase by79 centimeters (Department of climate change, 2009). Further, it enhances natural hazards affect on the coastal region as flood, inundation, erosion, and storm surges, which will be a significant threat to the coastal community (Button et al.2013). In addition, sea level rise causes a significant change to beaches, coral reefs, estuaries, wetlands and low-lying islands.

The Sea Level has increased over the past 200 years as average global temperatures have increased. The rise is due to two factors, the freshwater being added to the oceans from ice melt in the cryosphere, and the thermal expansion of the oceans due to rises in sea temperature. The sea level has risen 6 to 8 inches in the past 100 years. It is predicted to rise another 50 to 90 centimeters in the next century. As the sea level rises it’s jeopardizing rapidly growing coastal communities, which causes evacuation in some areas causing people to lose their homes. Sea level is the effect

Australia has Beautiful coasts, habitats and an abundance of land, climate change can destroy all of this. Climate change effects not just sea level rises but also weather patterns, global temperature, water quality and ecosystems. The threat of rising sea level is big *gestures towards power point* this image shows the Gold Coast when sea levels rise less than a meter; most of Carrara is underwater, not to mention all the areas where water might flow *power point gesture*. The climate also affect the oceans acidity and temperature which greatly affects the oceans ecosystem and our loved Great Barrier Reef. The Great Barrier Reef is classed as the largest living Earth, however the warm ocean temperatures are killing the algae that sustains the reef without it the reef will die. Many businesses rely on the reef to make a living, not to mention when the sea rises many homes will be lost all across Australia. If nothing is done about climate change, there will be repercussions within your lifetimes.

Decades of research suggest that sea-levels are rising, and will continue to rise as a result of climate change. This rise will have the most immediate and significant impact on

The following report will display the current research and views that scientists have on climate change. The first source is “Climate change in the South East Queensland Region” which was published by the Queensland Government. Source 1 will be used to study the consequences of climate change expected of global climate models. The second source is “Climate Change Reconsidered II” published by The Heartland Institution of Chicago. Source 2 will be used to assess and critique computer model predictions on climate change. “Climate change in the South East Queensland Region” summarises the expected future changes in climate for the South East Queensland region. The document predicts future climate change averages under different greenhouse gas

The Murray–Darling Basin is facing the challenge of climate change, including estimated increases in temperatures and evaporation, and a reduce in precipitation and runoffs to the rivers and wetlands, particularly in the southern MDB (Dunlop and Brown 2008). A projected model that makes a comparison between the historical climate change and the 2030 expected figures conducted by The Commonwealth Scientific and Industrial Research Organization (CSIRO) suggests that, water yield in the MDB is estimated to decline, with median estimated reductions of 12% and 24% in end-of-system flows towards the end of 2030. Pittock and Finlayson (2011) pointed out, the frequency bushfire is also expected to increase due to climate change,

Leading scientists advise climate change will cause increases to the frequency and intensity of extreme weather events. Rising sea levels pose a significant risk to coastal communities, while the world’s oceans could become too acidic to support coral reefs and other calcifying marine organisms.

Rising sea levels are occurring from global warming and extreme climate change. The burning of fossil fuels and greenhouse gasses has released masses amount of heat into our atmosphere which is getting trapped, causing our earths temperature to rise. Our oceans have absorbed up to 80% of this additional heat. Our Earth is not used to the higher temperatures which has had a dramatic impact on Ice Glaciers, causing them to melt which leaves sea levels rising. This problem is on going and each and everyday we are all contributing to it.

Drought is another factor of climate change that causes severe damages to agriculture and livestock. The effects of drought on agricultural production and livestock holding can be a detrimental issue and result in quality dissatisfaction of products. The agricultural industry can be affected by drought both economically and environmentally. The economical effects of drought on crops and animals can lead to the loss of money and time. When droughts occur farmers lose money because they will have to spend more money earned from their
