Climate Change And Ocean Level Rise And Its Effects On Coastal Societies

The earth’s climate has been changing and will continue to do so in the future. It is only going to keep on getting worse and it is getting to the point where humans will most likely end up in a situation of life threatening diseases and even death. Contagious diseases are spreading menacingly due to weather extremes as heat wave, droughts, cyclones, floods, and tornados (Dhaka). That is just the start of the effect of climate change and its consequences. Many scientists have already warned that millions of people would die in this century because of climate change unless the major reduction in greenhouse gas emissions is made (Dhaka). However, there are more than just reducing greenhouse gas emissions to help solve for climate change.

In the future global warming is expected to have a warmer atmosphere. This will begin to lead to acidic oceans within high sea levels. The future is up to us and what we do to reduce the greenhouse gas emissions. The more we emit the larger future changes will be. Global average temperature is expected to warm at least twice as much in the next 100 years as it has during the last 100 years. An increase in the temperature and an increase in average temperatures worldwide implies more frequent and intense extreme heat events or heat waves. Global warming has already had observable effects on the environments glaciers have shrunk, ice on rivers, and lakes is breaking up earlier plant and animal ranges have shifted and trees are flowering sooner. We can prevent global warming in the future by saving gas, as well as the release of emissions, by walking more. Remember, by saving a gallon of gas you can help keep 20 pounds of CO2 out of the atmosphere. Eat greens, how much of the food in your grocery store is imported from across the world? Transportation is a major contributor of greenhouse gases. Eating locally grown food to reduce transportation emissions. Use less hot water: Simple social fixes like setting your water heater at 120 degrees, using low flow shower heads, washing your clothes in cold water or using the energy saving setting on your dishwasher can go a long

In present day, the ocean is warmer now than it has been in the past 50 years. In the article, " Signs of Climate Change", it says that in 1960 the average ocean tempature change was -.3 degrees but in 2010 the average tempature change in the ocean was .6 degrees. Where I live the tempature is still continuing to rise more and more each year. With warmer ocean tempature comes rising sea level. In present day the sea level has rose by 7 inches in the past 100 years. In 2100 th tempature is around 15 inches higher than it is in present day. Both of these things are causing more tropical storms to happen and is also making the beach less and less

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

The combination of these and other trends was an estimated average sea-level increase of 1.5mm per year between 1961 and 2003, which reached 2.4mm per year in the decade from 1993 to 2003. The decades prior to this trend showed only minor fluctuations in sea-level, suggesting that the current rate exceeds what could be caused by natural cycles. While the exact impact of rising oceans is difficult to determine, it is certain that the consequences will include some degree of flooding, integration of salt water into water tables, and a loss of land due to coastal erosion and submersion.6

As life scatters for its survival in a new world devoid of anything living, human extinction is soon to be imminent. The once lush Earth will either dry up or bury by immense snowfall; therefore, turning these places inhabitable by life. Don't fret, though. They are only predictions of what will happen in the near future so you can worry later. Climate change is arguably one of the most important threats that endanger life on Earth. This was the concern covered in my nonfiction reading, Six Degrees: Our Future On A Hotter Planet, by Mark Lynas. The increased use of fossil fuel and continue industrialization have caused many of the problems we faced in the 21st century in the form of Global Warming. It has created raging storms, drought, famine, and fluctuating temperatures across the globe. Although this is not a problem I face personally, it might be problems in my lifetime in terms of mounting air conditioning bill and lacking any water. Unfortunately, plants and animals are incapable of quick adaptation like us humans, and they are prime targets for climate change. By hurting the plants, we are decrementing our chance of cleansing the plagued atmosphere created by us. We are damaging the

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.

The very nature of our ocean is to rise and fall, to sway with the pull of the moon, and to churn violently as the winds howl. The ocean has been this way since its inception and it will continue to do so as the arrow of time marches on. There have been cycles in which the nature of the ocean has wavered, but an equilibrium is kept, and life adapts. However, in our grotesque folly, we have decided that this should no longer be the case. We have changed the nature of our oceans so suddenly that life is crushed by force exerted through this change. Temperatures rise without regard to ecosystem or environment. Glaciers sweat profusely from the bombardment of heat. Sea levels rise. The importance of the oceans to the world at large cannot be understated.

In the early 20th century people knew that they could cause changes to their local climates by, for example, leveling large portions of forests and over ploughing fields; but very few thought human action could affect the global climate. It wasn’t until 1958 that humans began to record measurements of carbon dioxide in the atmosphere, which revealed an increasing amount. This new data scientists were recording supported the idea of global climate change as real and that increased green house gases in the atmosphere would in fact cause the world’s climate to become warmer. In the 1980’s the world’s global temperature started to climb at a faster pace than seen before which helped the issue gain attention among the public, the scientific community,

First of all, There is strong evidence that global sea level is getting higher and will continue to rise during this century. There are some human activities, such as burning of fossil fuels and cutting down tropical forests, have gained atmospheric absorption of heat-trapping gases releases enormous amounts into the air. It means that the Earth’s surface temperature increases, and the oceans absorb that additional heat. There is no doubt that when the ocean is warmer, large ice formations, like glaciers and the polar ice caps, naturally melt back faster and add more water to the oceans. The melting ice caps are raising sea levels at an accelerating rate. According to Howard (2015), “A bombshell climate study published this week warns that

The oceans is an essential component to surviving, but it’s also one of the most affected by the climate change. According to the EPA website, the greenhouse gases emitted trap heat and this heat is increasing the temperature of the oceans around the world. Over the past three decades, the surfaces temperature of oceans has been increase higher than any other time period. The oceans are a vital part of surviving; it provides 50 percent of all the oxygen in the world. However, with surface temperature increasing, at a rate of 0.3 Celsius per decade, this will result higher sea levels and higher ocean currents. The ocean is an important part to humanity, it provides millions of people with a source of food, and the change in temperature will cause many ocean species to immigrate to a more suitable habitat.

Today, climate change is affecting our lives and the world around us. However, many people would rather believe that nothing is wrong and that humans are not at fault for helping make the world what it is today. But there are still the few who do believe humans are at fault, and would like to do anything they can to help. The truth is, it is not too late to fix what we have done.

Climate change is one of the major issues surfacing earth over the past century. The earth’s temperature has increased over the years leading to detrimental effects on the economic and life sources of people, especially that of agricultural production and livestock. The Merriam-Webster online dictionary (2014), defined climate change as a change in global climate patterns apparent from the mid late 20th century. The Intergovernmental Panel on Climate Change, IPCC, (2007) predicts that by 2100 the increase in global average surface temperature may be between 1.8° C and 4.0° C. With increases of 1.5° C to 2.5° C, approximately 20 to 30 percent of plant and animal species are expected to be at risk of extinction. Moreover, the IPCC (2007)

In addition, destruction of property and submergence of coastal communities due to rise in sea levels will force large numbers of coastal residents to migrate inland. This will lead to overcrowding and competition for resources and jobs. The overcrowded conditions would allow diseases to spread
