(https://coastadapt.com.au/causes-of-climate-change-and-sea-level-rise) What is the major factor that is causing sea level to rise? There are two different agencies that cause sea level rises with respect to climate change. The first, being due to an increasing global temperature, causing seawater to expand. Taking up more space in the oceans basin and in theory cause a rise in sea levels. The second, being the melting of ice over the land, which therefore, adds water to the ocean.
While technology makes sea-level rise easier to observe, and some contributions to future sea-level rise can be predicted with increasing certainty, yet the ice sheets’ contribution cannot be wholly predicted. There is thus a risk that sea-level rise contributed by ice melting could be higher than the estimates provided by the IPCC. There is also, however, a possibility that the effect on sea level imposed by ice melting in Antarctica is minimal. Researches show that the East Antarctic ice sheet may thicken slowly in the future due to the increased snowfall. The increase in ice capacity in East Antarctica may cancel out the melting of ice cap in other parts of Antarctica, causing little overall melting.
Let’s move to the summary that I mention the three effects before. The global warming can affect a lot to the earth that the polar ice caps is melting so that it will increasing the sea level and it going to flood in the cities in the pacific. The global warming are the cause of heatwave droughts so that it will rising the temperature and it will make the climate change. The last one is the global warming will change the ecosystem. Overall of this assignment, I have understood that our earth is "sick".
Scientists have studies Earth's climate changes for decades, by analyzing many indirect measures of climate such as ice cores, tree rings, glacier lengths, pollen remains, and ocean sediments, as well as by studying the change in Earth's orbit around the sun. This study shows the climate system changes over time over a full range time scales. However, before the Industrial Revolution in the 1700s can be explained climate change by natural causes, such as changes in solar energy, volcanic eruptions, and natural changes in greenhouse gas concentrations. Recent climate changes cannot be explained by natural causes alone. The study indicates that natural causes are not only influenced our climate change in the 21st century.
The increase in temperature is melting the glaciers; causing a steady rise in sea levels. In “The Big Thaw” by Daniel Glick, rising sea levels are shown as a major problem to some coastal regions of the world. Due to rising sea levels, small islands will soon be engulfed by the water. This will result in thousands of lives and homes being destroyed. Glick says “Tuvalu, a small country in the South Pacific, has begun formulating evacuation plans.” However, Tuvalu is not the only area where evacuations are being held for the sake of increasing sea levels.
The average sea level has risen by approximately 8 centimeters per decade. The scientist predicted that the average sea levels will be continuously increased by 20 centimeters in the 21th century if the situation of the environment does not change over the next few years. Additionally, as the emissions of greenhouse gases into the air, the ocean absorbs the toxic gases, thus making the ocean more
It is easy to observe that the effect of global climate change on the Earth. For example, the rises of sea levels, glaciers, and polar ice caps are melting; numerous animals are emigrating to find other places to exist; trees are in bloom sooner. Scientists have confirmed that the temperature will keep on rising up for the next decades because of human activities in the industry (Alina). One of the biggest problems facing us now is global warming. It not only affects animals and plants but also the human population, which is indeed scary (Markham).
Some scientists believe that the warming is caused by human reason. Because they think that the world population is growing rapidly, this is the main cause of climate warming. People no protection measures for the environmental pollution at the same time, the forest has certain harm, ocean climate warming. I think this is part of the reason that cause climate change. But I think that the other reasons that cause climate change.
With continuous Ocean and atmospheric warming, sea levels will continue to rise at a higher rates than currently recorded this year. According to the NOAA tide data the sea rises Between 0.8 to 3.3 mm Per year with an average rate of 1.8 per year. Greenland and Antarctica together hold enough ice, that if it all melted sea levels would rise more than 80 meters. Rising tide data published by NOAA has suggested that low lying coastal areas will be affected the most by this problem. Places Like the low lying parts of the Netherlands, Brazil, Egypt, America, Japan, India, Indonesia, Vietnam and
⒈ Causes of climate change 1.1. Natural cause of climate change 1.1.1. Volcano eruption When a volcano erupts it throws out large volumes of sulphur dioxide, water vapour, dust, and ash into the atmosphere.  Sulfur dioxide gas reacts with water vapor commonly found in the stratosphere to form a dense optically bright haze layer that reduces the atmospheric transmission of some of the Sun 's incoming radiation. Aerosols can reflect solar energy back into space and have a cooling effect on the world.
