Heating Seas And Melting Ice Are The Consequences Of Global Warming

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)

The sea-level rise is due to climate change which is caused by rising ocean surface temperatures leads to more evaporation and increase in air moisture. Ocean warming also leads into coral bleaching which results into loss of structure and habitat.

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

While thermal expansion is difficult to observe on a small scale, such as a glass of water, it can have a significant impact on a massive volume of water such as the combined oceans of the world. Melting land ice, the other major factor in the sea-level rise, is a more straightforward issue. As global temperature increases, land-based glaciers and ice will melt sooner and accumulate later. Naturally, this runoff will lead to an increase in the total amount of water in the ocean.

The world warmed by about 0.7°C in the 20th century. Every year in this century has been warmer than all but one in the last century (1998). If carbon-dioxide levels were magically to stabilize where they are now (almost 390 parts per million, 40% more than before the industrial revolution) the world would probably warm by a further half a degree or so as the ocean, which is slow to change its temperature, caught up. But CO2 levels continue to rise. All this affect the ice pack in the Arctic. As temperature rises, ice melts. This causes many problems.

Rising sea levels has two main causes, increased glacier melt and the water itself expanding as it gets warmer known as thermal expansion (U.S.). The increased heat in water that is causing glaciers to melt and the water to expand is largely due to greenhouse gas emissions (U.S.). The dependence on fossil fuels by many countries around the world means that there will be difficulties in reducing continued damage to the atmosphere from greenhouse gasses (“Causes”). Another reason that greenhouse gas emissions have had such negative effect stems from the destruction of forests, particularly those in tropical locations (“Causes”).

As Earth’s surface temperature rises, the ocean also becomes hotter which results in an increase in sea level and decrease in Earth’s ice. “The oceans have absorbed much of this increased heat, with the top 700 meters of ocean showing warming of 0.302 degrees Fahrenheit since 1969” (“Climate Change: How Do We Know?”). Since greenhouse gases are trapping energy from the sun, the oceans absorb more heat which ultimately increases surface temperature. Oceans are able to absorb large amounts of heat energy because water has a greater heat capacity than air. As oceans become warmer, the frozen water on Earth melts at an accelerated pace. The thickness of Arctic Sea ice has dramatically declined throughout the last several decades. “Arctic sea ice

The sun power and warm’s are earth, as two thirds of solar-energy enter our atmosphere as visible-light, the greenhouse effect absorbs the solar-energy to keeping the earth warm and later releases one third back into outer space. Without the “natural greenhouse effect” the earth's temperature would be below 32 degrees fahrenheit (The freezing point of water). The burning of fossil fuels as an energy source releases a variety of gasses such as Methane, nitrous oxide, and CO2 adding to the greenhouse effect. Because of this heat is kept longer, warming our atmosphere and causing what we know as global warming. One of the issues with global warming, is the destruction of ice polar caps that contributes to the rise of the ocean level, and causes

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

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.

As ocean temperatures increase due to global warming they increase ice melt of these ice sheets and glaciers by melting the floating ice from below. If the air temperatures increase then the ice will begin to melt from above, creating pools of melted water that will in turn melt more of the surrounding ice. This may not always result in a problem as it’s expected that ice sheets reduce in size in the summer months but recently what has been found is that less ice is formed during winter so in total the ice sheets and glaciers are being reduced in size, adding more and more fresh water to our

Even though we have all of these consequences that come from climate change, these consequences do not come anywhere close to the problem of sea levels rising due to the fact of climate change. Sea levels’ rising is the worst consequence of climate change. Before we can understand why it is the worst we must first understand what sea levels are and why they are happening. Sea levels are the measurements and average surface of one or more of earth’s oceans. The rise of sea levels is caused by the melting of glaciers and the Atlantic Ice. This melting is caused by the climate change which rises the temperatures of the where the ice is, which causes it to melt and the water temperature rises which also assists in melting the ice. For example is the Muir Glacier in Alaska.

Global warming causes a rise in sea level because of two main phenomena: thermal expansion of warming ocean water and melting of glacial ice. A water level increase as significant as twenty inches could be reached by the year 2100. To provide a working idea of this, twenty inches is enough to submerge about 8500 sq. miles of the southeastern coastline of the United States (New York Times).

Water takes up a larger percentage of the surface of our Earth than does land. The earth’s oceans are vital aspects to our environment and it is necessary that we take care of them. On another note, global warming is an issue that is having effects on almost all aspects of our environment. Global warming itself means a gradual increase in the temperature of our Earth’s atmosphere over large periods of time. There is evidence that global warming has occurred in the atmosphere, however, now we are beginning to see its effects in the world’s oceans, as well. Though some may not see the connection that it has with the oceans, it has had quite a profound effect on our Earth’s oceans. As I mentioned before, oceans are environments that must
