Industrial pollution, the release of carbon dioxide, methane and other harmful gases into the atmosphere from burning fossil fuels and other industrial activities, causes a rise in temperature that leads to global warming. The oceans absorb most of the extra heat produced by human activity, especially that of industrial pollution. As a consequence many drastic changes, with lasting impacts, occur in our planet, such as, sea levels rising. (MacMillan) “When water heats up, it expands. About half of the past century 's rise in sea level is attributable to warmer oceans simply occupying more space.” (NationalGeographic.com), this is known as thermal expansion. According to Denchak, 8 degrees Fahrenheit is enough to bring about serious …show more content…
Lastly, constant flooding will force people living in coastal areas and other areas susceptible to inundations to evacuate and leave their homes and belongings behind. As shown in this picture by Kennedy Warne for National Geographic, families in Kiribati living in marginal areas are forced to construct their houses higher above ground because the increased flooding from high tides. Sea levels rising are a major threat to our economy as well. For example, farmers are struggling to keep up with changing weather patterns and increasingly unpredictable water supplies. Unexpected floods damages crops and causes the loss of top soil. In addition, infrastructure and transportation are at risk. (edf.org) “Hot weather, flooding and other extreme weather events damage infrastructure, put heavy burdens on electrical supplies and disrupt how we travel and commute.”(edf.org) “The tourism and real-estate industries in coastal areas are likely to take a hit as prime beachfront properties and recreational areas are washed away by rising waters.” (Harvey). Locally the impact of sea levels rising is great. Miami is already experiencing some of the consequences because of its proximity to the ocean and the low elevation. “According to a November Miami-Dade County Commission report on global warming, Miami 's causeways — the Tuttle and Rickenbacker specifically —
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.
People living in Miami are in the face of danger, and for the most part they are not aware of it. Due to high population, Miami is the fourth largest city to become affected by sea level rise. (Ankum et al.) In the next 32-50 years, sea level is expected to rise by as much as two feet. (Ankum et al.) This two-foot rise will have detrimental effects on the urban settings of Miami. The amount of soil erosion that is undergoing at our beaches will greatly increase if a two-foot rise occurs. At a four-foot rise, road connectivity would begin to become affected. At a six-foot rise, Southern Florida would no longer be habitable as it would, for the most part, be underwater. Not much is being invested in mitigation efforts, most of what is being done are short term solutions. Instead of coming up with ideas to prevent and try to slow down the effects of climate change on our environment, we are focusing on ideas such as building up a sea wall, relocating power plants, and redesigning structures.
Since 1880, records show that the sea level has bone up 8 inches. If it goes up six more inches, as the current studies indicate could happen within 20 years, South Florida’s flood control would be devastated. In South Florida, taxpayers are already paying the price for climate change as salt-water pushes through porous bedrock into coastal drinking-water supplies, and rivers and canals choked by heavy rains have a harder time draining into the ocean.
Miami, Florida experiences a great amount of natural disasters; however, one of the largest disasters Miami fears is affects of global change. Rising global temperatures scares most environmentalist in the Miami area, because rising temperatures results in rising sea levels. So, what is the problem with rising sea levels? Well, environmental specialist has made predictions that the rising sea levels could submerge the beaches of Miami.
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
The overview of vulnerabilities isn’t fully addressed, the climate change is resulting in significant impacts to Massachusetts coastline and ocean waters. The coast is modestly changing in temperature having an impact on sensitive ecosystems, threatening biodiversity and ecosystem-based economies, based off fisheries, tourism, and recreation. Sea level will impact development, infrastructure and natural systems from erosion and storm damage. Impacts may also include loss of life, extensive property damage, destruction of public infrastructure; releasing of sewage, oil,debris, and other contaminants; and loss of commercial and marine-related businesses critical to local,regional, and state economies. Also, areas such as coastal salt marshes,barrier

Miami-Dade County in Florida has long been a national famous spot for the risk of sea level rise and the amount of exposed assets. According to the National Wildlife Federation report, Miami is facing up to a $3.5 trillion loss by 2070, due to sea level rising caused by climate change . Global sea levels are raised by warming oceans, melting glaciers and ice sheets. Water can reach any level through various combinations of tide, storm surge and sea level rise. The common elevation above the local high tide line is dynamically set to be three feet based on historical average of the highest tide level each day from 1983 to 2001. Land below three feet in Miami is facing high coastal risk and social vulnerability for a 73 percent risk of at least
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
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.
Rising temperatures are causing melting glaciers, which cause rising oceans. Rising oceans will envelop entire coastal cities, killing or displacing millions of people. Our food sources will dwindle; entire species of animals will become extinct as we destroy their homes to rebuild; and as our population skyrockets, an unimaginable number of humans will be left homeless, starving, and sick.
Today, sea levels are rising from the effects of global warming. There are two main causes of the rise of sea levels are thermal expansion and the increase of the melting of land-based ice (US Department of Commerce, and National Oceanic and Atmospheric Administration, 2008). Humans burning coal and oil and cutting down tropical forests can have increased atmospheric concentrations. Causing the earth’s temperature to rise, glaciers and ice sheets to melt, thermal expansion to appear, and sea levels to rise (Causes of Sea Level Rise: What the Science Tells Us, 2013). Due to rising sea levels, 13.1 million Americans must be displaced from their homes along the coast. Since 1880, the planet has warmed by 1.4 degrees Fahrenheit
The flooding would mainly be because the water levels get so high that they cover over land in the cities. Some coastal cities in the U.S.A. have floods multiple times every year because of the sea levels rising. Cities may also have their drinking water contaminated by the salt water from the ocean. When the seawater is coming up onto the shore it may get into the water sources that are in the ground that so many people in the coastal cities rely on. The freshwater sources underground are called aquifers, and water that is in the ground makes up for most of the freshwater in the world. Another thing that would happen if these aquifers were contaminated would be that the farming would be interfered with. The water that people use for irrigation is usually the same water they get for drinking. The water would be saltier and would stunt or kill crops. Making freshwater from saltwater is expensive and unsustainable. Plants would be affected by the water creeping closer up on the shore too. If the water seeps into the soil that plants are living in it would make the soil saltier and plants may stop growing by the shoreline. Trees would have a really hard time because they would have to work harder to pull the water out of the salty soil and that may stunt their growth or kill them. The sea level rising would also affect wildlife too, as many species of wildlife make their home on the
and flooding. San Francisco, New York City, New Orleans, Seattle, and Miami all experience major flooding from the ocean level having risen so high. Thousands and thousands of people perish each summer across the USA alone—hundreds die in Chicago as the temperature soars to 100 for 2 weeks straight.
