An issue that is felt throughout the world is Anthropogenic Climate Change formally known as Global Warming. This word wide problem is one that needs to be addressed immediately as well as long term. Anthropogenic Climate Change is the rise of the earth’s temperature caused by human activities. The continuing rise in the earth’s temperature will cause extreme change in our earth’s ecosystems. The predetermined course to our ecosystems relies on climate change and its effects on ecosystems and life as we know it is at a vulnerable state. Anthropogenic Climate Change shifts relations with human life and presents severe biodiversity in
Sea-level rise is one of the most significant effects of climate change. As global temperatures rise, ice in the polar-regions will continue to melt, dumping tons of additional water into the ocean. Warmer water temperatures will also lead the oceans to expand high projected rates of future sea-level rise. “These factors will cause sea levels to increase and swamp coastal areas all over the world” (Oceans and Sea Level Rise). Particularly, countries which are located in low-lying areas as well as islands, are concerned that their land areas would be decreased due to inundation and coastal erosion and, at worst, a large proportion of their population may be forced to migrate to other countries. Although flooding is an obvious consequence of rising sea levels, there are numerous other effects to consider. The current rising sea levels due to global warming are effecting the environment in a number of ways. (Oceans and Sea Level Rise)
Over the past couple of decades, the world has recorded the highest rates in rising sea levels. Statistics are drawn from tide gauge readings, and core samples have revealed that the Global Mean Sea level has risen by ten to twenty centimetres. However, over the last twenty years, the annual rise rate has been 3.2 millimeters a year. This is nearly double the average speed of the previous eighty years. The rise in sea levels means that destructive surges of storm push further into the mainland than they previously did, this also means that there are more cases of frequent nuisance flooding. While we can describe the rising of the sea levels as a natural process, the recent trends are a major cause of concern because the sea
A rise in sea level will most likely affect coastal, deltaic, and low-lying populations and ecosystems. Still, more of global coastal areas are being developed for the demand of growing populations. According to World Resources (1998-99), “sixteen of the world’s largest cities with populations of more than 10 million are located in coastal zones.” Coastal areas in particular will be affected severely in terms of beach and coastal erosion, permanent inundation, temporary flooding, and increased water salinity – among other things - are possible environmental consequences of sea level rise. For the United Kingdom “a 1 meter/yr cliff retreat rate would increase by 0.35
Global warming, also known as climate change, is the ascent in the average temperature of the earth’s climate. It is caused by the “greenhouse effect”, which is the accumulation of carbon-dioxide(C02) and other pollutants and greenhouse gases in the atmosphere which absorb solar radiation which is normally reflected back into space. Although it is caused by various factors, the largest sources of this heat-trapping pollution worldwide are the burning of fossil fuels for electricity and transportation. The global temperature is rising rapidly. “Over the past 50 years, the average global temperature has risen at the fastest rate in recorded history” (MacMillan). The majority of the scientists and scholars agree that this rapid increase in global temperature leads to many environmental, social, economic, and political problems. Global warming has been an affair of controversy in the past few decades. Every national and international scientific body agree with the existence of this phenomenon. However, a limited number of scientists still argue against its existence. Global warming is real because with the passage of time, its effects are becoming more apparent and there is abundant scientific evidence that corroborate its existence.
Climate change is evident throughout the world and is a major issue. It is no secret that our planet is getting warmer. Global warming is now recognized in the scientific community as a real problem. There are multiple aspects that are causing this issue. Majority of the warming is caused by greenhouse gases. Volcanic eruptions and changes in the intensity of solar radiation have offset the warming partially. It is estimated that average annual temperatures will increase 3.5°F-9.5°F by the century’s end.
Rising sea levels can also erode shorelines, which will in turn make flooding more severe. Another severe effect of rising sea levels is saltwater intrusion. Saltwater intrusion occurs when saltwater intrudes into groundwater, contaminating drinking supplies, irrigation supplies, and agricultural fields (“Sea Level”). As the ocean temperatures continue to rise, sea level rises with it as seen in Figure 1. This graph shows the rate at which sea levels are rising as ocean temperatures rise. Rising sea level can be contributed to two factors, thermal expansion and melting of sea ice. Since the 1970’s, the sea ice in the Arctic Ocean around the North Pole has been shrinking, and getting thinner. The warmer water and atmosphere causes the Arctic sea ice to melt more than usual during the summer months. Not only will the melting of sea ice have
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
However, issues the occur with rising temperature involve more severe floods, storms, droughts and fires which could then lead to higher death toll in human and animal life because for some animals it will be too hot to live. Due to this rise in Temperature Sea, level has increased dramatically and scientist estimate that the sea will continue to rise 15-95 cm by the end of the century. Sea levels are rising because two reasons. First with increasing average global temperatures, the water in Earth’s oceans expand in volume. This occurs because, when heated the molecules that make up a body of water move more rapidly and collide more often. The second reason is when glaciers and ice sheets melt the water that had previously been frozen the glaciers will melt and release the water cause more enter the oceans and
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
According to Alina Bradford’s article “Effects of Global Earming”, one of the most dramatic effects of global warming is the reduction in Arctic sea ice. The average temperatures in the Arctic region are rising twice as fast as they are when comparing to other places in the world. The ice in Arctic is getting thinner, melting and rupturing. The polar ice cap as a whole is shrinking. According to the images from NASA satellites show that the area of permanent ice cover is contracting at a rate of 9 percent each ten years. If the ice melting at this rate, Arctic could become ice-free in the summers by the end of the century. As global temperatures continue to rise, ice in the polar regions and glaciers will melt, dumping tons of extra water into the ocean which cause sea level to rise. According to the data in the article “Causes of Sea Level Rise: What the Science Tells Us”, “Global average sea level rose roughly eight inches from 1880-2009 and the average annual rate of global sea level rise accelerated from 1993-2008, increasing 65-90 percent above the twentieth century average”. Sea level rise means potable water will decrease. Although about 71% of the earth surface is covered by water, but 97% of the water is salt water. Ice melting will only increase the yield of sea salt water. People cannot drink the water from the sea because there are too much salt in it. Although because of the
One of the current issues in the world is the receding glaciers in Bolivia, and they are affecting the community quite heavily. The glaciers have receded 43% between the years of 1986-2014, and with the current warming they are continuing to recede. One of the main problems this is causing is a risk of the water supply in the region. In Bolivia, they use melted glacier water for many things such as irrigation, drinking water, as well as hydropower. The article explains that around 15% of the water they use is from the melted glaciers, with that number coming close to doubling when they are in a dryer season. This also causes problems for the lakes and rivers in parts of Bolivia. Some of the melted glacier water finds its way into rivers, lakes, and other bodies of water, and quite a few bodies of water have dried up due to these receding glaciers.
Due rise in temperatures, icebergs and ice crust will melt, what by the way will force sea-level rise and flood islands and continents. If Earth’s oceans water levels will continue to rise, it may also influence on the amount of fallouts, which may destroy living environment and habitat of different species.
Intro: Global warming is a horror that you’d never think would affect you, but can give you that rude awakening when your house is slowly submerging, due to rising sea levels, or when you step outside and it gets that much harder to breathe, or realizing that these
Sea levels have been rising over the past century, but the most significant change has happened over the past decade. The rise of sea levels is caused by two main factors: melting land ice and the expansion of sea water. Throughout this century the rate of global sea levels rising has been about 6.7 inches, but the rate has doubled over the past decade. This reveals that the rate of rising sea levels is speeding up and could have a major impact on island and coastal life (“Global Climate Change”).
