Global Warming And Sea Levels

As Earths average temperature increases every year, the discussion of climate change has become a significant topic in the scientific community. Human activities such as powering factories, running automobiles or something as simple as burning wood for heat, emit dangerous greenhouse gases. What makes these greenhouse gases so detrimental is that they absorb the heat radiating off of Earth and keep it in the lower atmosphere creating a “blanket” of warmth around the Earth’s surface. This causes a drastic increase in the Earths average temperature. Due to the rise in temperature, the polar caps have been melting faster than ever, this is dangerous not only because of the risk of floods and sea level increase but ocean water will become less saline and ecosystems will be destroyed, impacting humans just as much as marine life. In the article, Understand faulty thinking to tackle climate change by George Marshall, Marshall states that most people in our world today do not care about climate change because it will not affect them, “Which points to the real problem: climate change is exceptionally amorphous, … no deadlines, no geographic location, no single cause or solution.” (Marshall 2014). Because the author makes it clear that climate change is indeed a great plight, and fails to be acknowledged by people, it is a significant matter that should be discussed

In all, Earth’s oceans are diverse systems that all of life depends on for survival. The oceans act as a large conveyor belt; transporting varying volumes of water do different parts of the world. Any kind of alterations or disruptions to this conveyor belt causes regional sea levels to rise. These alterations are greatly impacted by anthropogenic climate change, the long-term alteration of earth’s climate as a result of human activities. The main ingredient behind climate change is the constant changing of global temperatures due to increasing levels of greenhouse gas emissions produced by humans. Mankind became intertwined with climate change during the industrial

Persistently higher temperatures caused by global warming have led to greater than average summer melting as well as diminished snowfall due to later winters and earlier springs. This imbalance results in a consequential net gain in the rate of runoff to ocean evaporation, causing sea levels to rise dramatically. Sadly, many take slight notice towards this fact because it may not seem a dreadful and urgent effect at first. However, after concluding that a sum of forty percent of the world's population lives within one hundred kilometers of the ocean, the severity of this effect is clear. Thousands of major towns and cities will be flooded, putting millions of lives and billions of dollars' worth of property and infrastructure at risk. As the water reaches further inland, it can cause destructive erosion, wetland flooding, agricultural soil contamination, and loss of habitat for fish, birds, and plants. These are just what a single effect of global warming will cause, showing that this matter must be taken seriously by all. Remember, This planet is our home, which means it is our concern, and if we don't do something to protect it...who

The United States is made up of eight regions, Northeast, South East, Midwest, Great Plains, Northwest, Southwest, Alaska, and Hawaii. The report “Risky Business” touches on how these areas will be affected by rising sea levels, rising temperatures, or an increase in “extremely hot days” if the United States keeps on going about it’s business as usual. Every aspect of the U.S. economy is affected by climate change this means all our lives are influenced by climate change. The authors of this article communicated very clearly and effectively their points and evidence.

One important direct precursors that lead to the rise in sea levels include the emissions of greenhouse gases that lead to warmer temperatures (Gornitz et al., 2004). These changes in temperature can result in devastating effects on ecosystems and their inhabitants (Gornitz et al., 2004). It is also important to mention that the temperature in Connecticut has been gradually warming, and reports indicate that the temperature increase is much greater than the increase in the other parts of New England (Gornitz et al., 2004). On the other hand, an indirect precursor that can lead to the rise in sea levels include land use, topography, and land cover that can account for the changeability in temperature. For example, the increase cutting down

Climate change is a global problem that is affecting Earth’s delicate ecosystem. Many problems are present in our world today, such as starvation, flooding, heat waves, droughts and disease. These issues are likely to worsen as climate change takes its toll. In the past, the cause of this severe climate change was unknown. Today, it is known that manmade climate change is occurring. Scientists have discovered that humans have had the greatest impact on the Earth’s ecosystem. Human activities, such as burning fossil fuels and deforestation, are causing the Earth to get hotter. Although humans are not the only cause of climate change, we contribute to this world wide problem because of the actions we take, which if affecting us now and will continue to affect us in the future.

In addition to carbon dioxide levels and surface temperatures, oceans also provide scientists with evidence of climate change. Oceans play a major role in climate change because they absorb almost all (90% from 1971-2010) of the energy increase in the climate system (“Summary”, 2013, p. 8). Scientists are confident that ocean surface temperatures have increased since the beginning of industrialization (“Summary”, 2013, p. 8) and that humans have contributed to this ocean warming (“Summary”, 2013, p. 17). From 1971-2010, ocean surface temperatures have increased approximately 0.4-0.5°C and are projected to increase by 0.3-2.0°C by 2100 (“Summary”, 2013, p. 8). However, temperature is not the only effect of climate change on oceans; other

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)

Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and the lakes are breaking up. Earlier plant and animal ranges have shifted and trees are flowering sooner. Effects that scientists had predicted in the past and would result from global climate change, are now occurring. There is a loss of sea ice, accelerated sea level rise and longer more intense heat waves.(3) Each of the past 37 years has been warmer than the 20th century average. The twelve warmest years on record have all occurred since 1998. The hottest year ever recorded for the contiguous United States occurred in 2012. Globally, the average surface temperature has increased more than one degree Fahrenheit since the late 1800’s. Most of that increase has occurred over just the past three decades. Scientists have high confidence that global temperatures will continue to rise for

Sea levels have been on the rise ever since the start of the industrial revolution, some aspects of this rise are natural and some human induced. Sea level rise (SLR) has many different effects on global systems including, flooding, saltwater intrusion, salinity and density. These changes will ultimately effect around 40% of the world population, which live within about 100 kilometers of a coastline (Union of Concerned Scientist, 2011). These increased effects will put millions of people at risk of displacement. As stated earlier sea levels have been rising (slowly) since the industrial evolution, but in the last few decades (early 1990s) there has been a significant increase (see figure. 1)(Nicholas & Cazenave 2010). A

Contemporary climate scientists agree that global warming is a critical concern in the 21st century: rising sea levels and increasing temperatures ranging from 1 to 6 degrees Celsius are harming Earth’s physical, ecological, and social conditions. Lower temperature predictions estimate that ocean surfaces have warmed .3 to .6 degrees Celsius over the past 100 years (Houghton). While these numbers seem insignificant, they are rising rapidly over time. Fore example, the warmest 30 year period in the last 1400 years lasted from 1938 to 2012, resulting in temperatures .65 to 1.06 degrees warmer than previous averages. The impact of this warm period

Global warming has become a very big problem in our world today. It has created everything from bad air quality to water pollution in our world. These are just some of the consequences of global warming. However, I would like to speak on one topic as it regards to global warming. We have now discovered that global warming is causing our polar ice caps to melt thus creating rising sea levels. This has become a very large topic, and many scientists are scrambling to find solutions to stop this problem. If the rising sea level isn’t fixed we will see a massive amount of damage caused to our coasts, and coasts around the world for that matter. The consequences would also be dire for my home state of Florida. Florida is susceptible to rising sea levels because so much of the land is barely above sea level. The consequences in Florida would be detrimental. Consequences of rising sea levels could affect our economy, human quality of life, and the environment.

Our global climate change has not always been a top concern for scientists, politicians or even our very own view on the rapid rates of global warming data. The drastic change and harm that has occurred to the nature around us has become a huge concern that must be dealt with appropriately and done so in a timely manner, with rapid glacier melting that has caused rising sea levels or the .15-degree temperature increase per decade since the 1900`s we can noticeable see the change our earth has endured due to humans. Even the smallest change of a degree in temperature not just in the U.S but globally has effected many aspects of Earth itself. Just a couple of years ago in the year 2014 our planet reached

As the earth’s oceans become warmer, they expand, causing sea levels to rise. As the temperature continues to rise, sea and land ice which together hold more than 70% of earths fresh water are rapidly melting. Polar ice sheets are currently losing 268 Gigatonnes of mass every year and Arctic sea ice is disappearing at 13.3% per decade, with climate scientists predicting that by 2050 the Arctic Ocean will be completely ice free in summer. This will have huge environmental impacts, endangering countless of species and changing currents and weather patterns. This rapid change will destabilise the climate, resulting in extreme and more frequent flooding, drought, rainfall, storms and wildfires. Unless there is a change in the overindulgent and unsustainable way in which we are living the future of planet earth looks bleak.

A topic of worldwide concern is the effects of global warming on the world we live in. Our awareness of this event is elevated due to our part in accelerating the rate of global warming through the excessive production of greenhouse gases polluting the atmosphere. The changes due to global warming are small but long-reaching, slowly and slightly changing the world around us, raising sea levels and temperatures. This change is viewed in a negative light as it is disrupting the current state of nature and altering the environment. Natural, we want to resist any negative changes and would rather sea levels stay at a constant level to protect beaches and coastline cities. We like to be able to control as much as we can to sustain ideal
