The issue is that the sea water levels are rising as a result of warming oceans caused by climate change. The burning of fossil fuels has put lots of “greenhouse gases” such as methane into our atmosphere, causing more heat to be retained on the earth from the sun and overall warming the earth. The oceans absorb about 80 percent of the excess heat. Thermal Expansion is in effect as the sea levels rise. Polar ice caps and glaciers are melting due to global warming which is adding to the rising sea level. (National Geographic, 2017)
Recent studies (such as Wigley and Raper, 1987) have shown that 2 to 5 centimeters in sea level rise, in the period of 1880-1985, can be explained by thermal expansion (Warrick, 1990). Moreover, studies (such as Meier, 1984) have found evidence that 2-6 centimeters of sea level rise can be explained by the melting of glaciers (Warrick, 1990). According to the International Programme for Climate Change’s estimates sea level will rise between “0.3 and 1.0 meter by 2100, with a best-guess estimate of 0.5 meter” (World Resources, 1998-99).
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.
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
For many years now, scientists have believed that our climate is changing. This climate change has caused water currents up north, near Antarctica to shift leading to warm waters taking the place of the usual cold arctic waters. Warm water melts the glaciers and causes the top of the glaciers to float off into the sea, allowing the warm water to melt even more glaciers. The extra glacier melting into our sea has caused the sea levels to raise and the
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
Research shows that global sea level rose about 6.7 inches in the last century. The rate in the last decade, however, is nearly double that of the last century.
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
Warming seas and melting ice are the consequences of global warming which is the heating of Earth caused by greenhouse gasses trapped in Earth’s atmosphere. Global warming causes the heating of Earth’s seas, and when the water molecules in these bodies increase in temperature, they thermally expand which causes the sea to rise. The heat is also causing the melting of Earth’s ice sheets, and when the ice turns to water, it causes the sea to rise as well. Note that the water does not rise evenly. The sea level may increase in some areas as it may decrease in other areas. Sea level rise is inevitable because of the greenhouse gasses that are trapped in the atmosphere, they will always increase sea level to some degree. However, the decisions we
With warmer water and the melting ice, the water level will rise because the ice is becoming water. Thermal expansion has already raised the oceans 4 to 8 inches in one-hundred years. This rise would pale in comparison to what would result if Greenland's massive ice sheets melted. If this worst-case scenario were to happen, it would raise the sea level twenty-three feet worldwide. Such a rise may engulf cities that are located at or near sea level. Major cities from Los Angeles to London would be submerged (Lovgren). Rising sea levels would also lead to coastal flooding on the Eastern seaboard, in Florida, and in other areas such as the Gulf of Mexico.
Humans have had a huge impact on climate change and are mainly the reason that change is even happening, as over the past hundred years they have been releasing large amounts of carbon dioxide and greenhouse gases into the atmosphere. Greenhouse gases are mostly the result of the burning of fossil fuels, but they are also the result of activities such as deforestation, some agricultural practices and industrial processes. The effect that these greenhouse gases created have on the climate is that these gases create like a ‘blanket’ around the earth, trapping any energy in the earth’s atmosphere and therefore causing the climate to warm. This is what is known as the greenhouse effect. Although this is natural and it
The rising of the oceans is an effect of the lost in the ice masses at the poles. This is evident from what Alina Bradford and Stephanie Pappas wrote about in their article titled “.effects of global warming” that “Global sea levels have
Sea levels are affected by glacial melting because all of the water from the glaciers will go
Last but not least, global warming has caused the polar ice caps to melt. The melting of the polar ice caps will cause the sea levels to rise all over the world. If the sea levels rise just a metre
