Causes Of Sea Levels

Rising sea level can be caused by a variety of factors and can have an effect or influence even more. Future changes in sea level may impact human populations around the world and many other aspects of life on Earth more than many initially thought. The U.S. coast of the Gulf of Mexico is on track to be one of the most impacted by further sea level rise and the outcome could be detrimental to the entire coastline.

In coastal flooding the coastal areas are flooded due to storm activity at sea. The waves break through coastal defenses and submerge the area.

Oil and gas exploration, pipeline canals, and navigation channels have allowed saltwater to intrude into freshwater areas.2

Saltwater intrusion leading to contaminated drinking water wells has long been feared in South Florida. Saltwater intrusion occurs naturally to some degree in most coastal aquifers, owing to the hydraulic connection between groundwater and seawater. Because saltwater has a higher mineral content than freshwater, it is denser and has a higher water pressure. There are three primary mechanisms by which saltwater contaminates the freshwater reservoir in the unconfined, surficial aquifers of the region: one, subsurface movement of seawater (lateral large-scale intrusion), two, seepage of seawater from tidal canals and streams, and three, upward movement of connate saltwater (water remaining from the

Besides the direct effect of sea level rise, coastal flooding may also be a more prevalent and severe issue. For example, “sea level rise of two feet, without any changes in storms, would more than triple the frequency of dangerous coastal flooding throughout most of the Northeast” (Horton 374). The higher seas would increase the initial level, so that the flooding level would be much greater, especially during hurricanes. Recent hurricanes have become a good example of how much damage can occur to both humans and animals. For example, much of the coastal infrastructure is in danger of damage, which can affect commerce and the public’s health and safety: “In New York State, two feet of sea level rise is estimated...To flood or render unusable 212 miles of road, 77 miles of rail, 3,647 acres of airport facilities, and 539 acres of runways” (Horton 379). This loss of infrastructure may occur in every coastal Northeast state, especially in the south. In these southern Northeast states, the land is flat, which makes them easier to inundate with water. In addition to infrastructure, transportation is also at risk, with much of the major highways (I-95) and trains (Amtrak) at risk of coastal damage (Horton 380). More affected by sea level rise, ecosystems near water may be permanently damaged in upcoming years, and according to Rob Deconto, a climate scientist at University of

Increased surface water flooding in low lying areas or heavy rainfall may overcome the capacity of the drainage system. There can also be damage to coastline structures due to storm surge, flooding and salt water intrusion.

When the sea level rises, this can be due to multiple factors including climate change and subsidence. Climate change and warming reports identify that “postglacial temperature has increased 13°F in the Gulf region” (Morton 22). This is important evidence because rising temperatures coincide with rising sea levels. As sea water warms, it expands and takes up more room causing sea levels to rise. Additionally, melting glacial ice cause the rise of sea level and is due to climate warming as

There are two major possible explanations that can trigger a sea level to rise. First, global warming that cause melting ice in the mountain, such as mountain polar ice and glaciers ice layers, which causing water is release into the oceans. Second, as ocean temperatures rise, the warmer temperature expands and the sea level to goes up. In certain parts of the earth, particularly in low-lying stream areas, local land is sinking, in result of sea levels increase to higher ground. It is worthy of mention that this theme is actually not new and probably one of the most interesting book dedicated to this problem is the novel by Sandy Florian.

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.

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

What humanity faces from the ramifications of this issue is immense. This research article will seek to convey and articulate if climate change has affected the rise of ocean levels, and if so what are the detrimental affects on coastal communities. This article will also reveal what specific regions and events that are happening that are elevating ocean level rise. The objective of this research article is to inform people about the plight that humanity has found itself in and how to prevent ecological damage and along with that prepare for the coming tide.

It is increasing due to the melting ice sheets. When there is a rise of temperature, the ice sheets from the Intertidal and Greece land start decreasing in volume. The thermal expansion is another reason that increases the sea level because it leads to an increase in storm surges and frequency of floods.

Ocean level is rising speedier in a few spots than others as a result of wind examples, sea streams, and different components. Furthermore, ocean level may appear as though it's changing more in specific spots than others in light of the fact that the land itself might rise or sinking.

The rise in sea level globally is caused by many things the main ones being water added due to land ice melting in Alaska, Greenland and Antarctica due to gravitational effects which has a significant effect on the ocean. With land in the northernmost of Washington rising this causes the relative sea level to fall. However in the rest of Washington, Oregon and California the land is sinking causing relative sea level to rise. and sea water expanding from warming up. In North west America is due to different factors. One of these is the climate aspect where the most important aspect is the occurrence of major El Nino. El Nino involves the Southern Oscillation which affects the winds and ocean circulation this causes the raising of local sea level when there is a warm phase (El Nino) ad lowering of the local sea is during a cool phase (La Nina). With the seasonal variations in the directions and speeds of the shelf currents and the changing directions of the coastal winds. These processes in turn produce seasonal variations in water temperatures.
