The Impact Of Climate Change On Australia's Surface Processes

The environment around us carries the scar caused by global warming. Precipitation has increased across the globe, which has consequently caused more frequent floods, an increase in sea levels, and a higher frequency of strong storms. Lakes are drying up, islands are virtually dropping into the ocean, and the polar ice caps are disappearing. The planet is truly in peril. This paper will focus on three regions of the Earth in particular: Antarctica, the Amazon Rainforest, and the Great Barrier Reef. More specifically, it will examine the extent of the impact that global warming has had on each region..

A climate change a change in global or regional climate radiation diagram , in particular a change apparent from the mid to late 20th hundred onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuel .. climate change has been found in many countries and regions like Uganda, The Alps, Australia and many more. but our focus here is on the climate change in Australia. Climate alteration has been a major issue in Commonwealth of Australia since the beginning of the twenty first century. In 2013, a news report was released stating that Australia is becoming hotter, and that it will experience more extreme heat and longer flak seasons because of climate change. In 2014, the Bureau of Meteorology released a report on the common wealth of Australia's mood that highlighted several key points, including the dramatic step-up in Australia's temperatures and the increasing frequency of Bush fires, droughts and floods, which have all been linked to climate change.

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.

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.

The high (A1fl) emission scenario displays results if fossil fuel dependence continues to increase. Currently, greenhouse gases are being emitted at a rate faster than the highest scenario (A1fl) predicts. Source 1 incorporates historical data provided by the Bureau of Meteorology (BoM). This information assisted in the creation of future climate change projections for Queensland which were prepared by Commonwealth Scientific and Industrial Research Organisation (CSIRO). The document also uses information reinforced by reliable sources such as the Department of Infrastructure of Natural Resources & Mines and Queensland Regional Profiles. These references are current as of 2004-2009. Climate is the long term average of weather conditions. Climate is generally recorded, updated and averaged every 30 years. Climate change is a change in global or regional climate patterns largely attributed to by increased levels of carbon dioxide present in the atmosphere. Source 1 defines climate change as an event that has reached the limits of natural variability. The document doesn’t explain how climate change happens or how it can be changed. It briefly explains the advantages of reducing fossil fuel use. Source 1 does – however – give an in depth overview of the impact of climate change for the future. The creation of “Climate change in the South East Queensland Region” relied on the use of; historical data records, tables and graphs, the IPCC emission

The first argument examined on the man-made global warning side is that increasing greenhouse gases caused by human activities is causing directly observed climate changes. The first resulting climate change discussed is warming global surface temperature. There has been an increase in global surface temperature of 0.74 degrees C since the late 19th century. In the last 50 years alone the temperature has increased by 0.13 degrees C per decade. North America and Eurasia have seen the largest increase in warmth. However, some areas of the earth have actually cooled some this past century (Easterling & Karl, 2011, para6). After the mid 20th century 70% of the global land mass saw reduced diurnal temperatures. From 1979 to 2005 the maximum and minimum temperatures have shown no change; both indicate warming (Easterling & Karl, 2011, para10). Furthermore, borehole temperatures, snow cover, and glacier recession data all seem to agree with recent warming (Easterling & Karl, 2011, para11).

The rising temperatures of global warming has initiated the melting of ice sheets, contributing to global sea-level rise. Sea levels are expected to rise more than a metre beyond existing ‘stable’ tidal range positions, resulting in new inundation of land and shifts in shorelines. Inundation and coastal instability because of erosion, exaggerated by the extreme weather events caused by climate change, is a key risk for coastal areas such as the Gold Coast.

Climate change is a rising issue of importance in our day and age, and one that is threatening our global society on many levels. In the past few decades, scientists have discovered that our planet’s climate has been changing at an alarming rate. The way in which we have changed the land to

Climate change has been a topic of debate for decades. Scientists support climate change is happening with hard scientific evidence whereas the people who oppose climate change have evidence which is mainly opinion-based. This report will cover what climate change is, why climate change is happening, the science that supports climate change, the different views and opinions on climate change, the effects of climate change around the world and particularly the effects in New Zealand, my opinion on climate change and my conclusion on the issue.

When you hear the words “climate change” what comes to mind? Probably weather and the changes. Many of us watch the news or use an app on our cellphones/electronic devices to keep an eye on the weather for the day, week, or even the month. But, there is actually a difference between weather and climate. Weather is actually “the changes we see and feel outside from day to day. It might rain one day and be sunny the next. Weather also changes from place to place” (Dunbar, 2014). Whereas “climate is the usual weather of a place. Climate can be different for different seasons. Different places can have different climates” (Dunbar, 2014). This paper will focus on the ins and outs of climate change, specifically focusing on what climate change

My extended essay topic will be the climate change in Australia. The question I want to investigate is the impacts of climate change in Australia and the solutions of the climate change. Climate change is tested by an increased in temperatures, the concentration of haze and amounts of rainfall. Climate change is definitely relevant to the Australasia because Australia has one of the world’s largest global warming emissions rates. The climate change in Australia causes many problems due to the fossil fuel are burned. First of all, the climate change increases the frequency of extreme weather events, such as the spring of 2013 has been Australia’s warmest on record. The temperature for the season was 1.57°C above the 1961–1990 average. Humans

Global warming is a phenomenon leading to climate change. Human activities, especially the burning of fossil fuels releases large amounts of greenhouse gases. These gases absorb infrared radiation and cover the atmosphere. More and more infrared radiation is inside the Earth, which becomes warmer. This process is called global warming (Houghton, 2005). Australia is one of the countries, which is suffering from climate change. The average temperature of Australia has increased by 0.7°C since the past century. Average precipitation in the southwest and southeast in Australia will decrease in future decades, while northwest regions will increase in precipitation. Moreover, Australia’s coastlines will suffer from erosion and inundation because it is estimated that there will be an 8–88 cm increasing global sea level (Preston and Jones, 2006). Owing to climate change, Australia’s biodiversity, ecosystems, and natural habitats are destroyed. For example, the habitat of the Great Barrier Reef and coral communities are disappearing (Preston and Jones, 2006). Owing to the effects and it is energy crisis in the future, exploring the renewable energy source feasibility and sustainable development is necessary. Therefore, in the long term, the potential of wind energy and solar energy could be the answer to global warming in Australia and determine the current barriers to renewable energy in terms of the energy industry and the locations in Australia.

In the last 100 years, Earth’s average temperature has risen by 1.4°F. The rising global temperatures have caused changes in weather and climate. Global warming refers to the ongoing rise in the average temperature near Earth’s surface. This is causing a climate change, which refers to any significant change (major change in temperature, precipitation, or wind patterns) in the measures of climate lasting for an extended period of time (several decades or longer). Due to this, it is projected that the temperature will rise from 2 to 11.5°F in the next hundred years (US EPA, 2014). The “drivers,” which are the principal causes making this occur, are very controversial. It is debated whether a change in temperature is due to the work of

Over the years there has been a lot of controversy on if climate change is an issue that needs to be discussed and solved. There is a constant debate among scientist on if human actions are contributing the changing of earth’s climates. Climate change is defined as the change in average weather patterns for a specific region or Earth as a whole. This could include the change in an average temperature for a city or the amount a rainfall it receives (Dunbar, 2015). The main difference between weather and climate is the period of time specific patterns are recorded. Weather patterns are looked at over a much shorter period of time, meaning that these patterns are going to be more sporadic and change more frequently. Climate on the other had is recorded over a much longer period of time and usually show less drastic changes in patterns when compared to weather. Some people may argue that climate change is not an issue because Earth’s temperature is always changing do to natural effects. What people don’t realize is that human activity has effected the rate that earth’s temperature is changing, and just the smallest changes can lead to drastic consequences (Dunbar, 2015).
