Renewable Energy Sources Comparing How Effective They Are At Producing

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.

Climate policy makers have determined a 2 degree Celsius increase as a target for global warming. According to scientists if we stay within this target, sea levels will rise only a few meters, which would be manageable.

In a world divided by war, it is easy to overlook problems that affect all of mankind. The dramatic rise in ocean levels worldwide constitutes just that sort of problem. Although the fundamental problem of global warming has been given airtime and plenty of written-media coverage, the problem of rising sea levels seems to have met a

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

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

The oceans have been part of the earth before mankind was even thought of. Greenhouse gas emissions are changing them for the worse. Ocean levels are rising because of the thermal expansion of warming oceans, according to IPCC, this rising can result in many floods across America (Michael). The rising of the ocean can have tragic effects on our economy, meaning that rising in water will result in less area for many shore side organisms. If that's not enough Climate Central predicts that 140-160 million houses and building will be below sea level in a century (Michael).

Sea level rise is another area of concern for scientists and the global community with respect to climate change. Since the beginning of the Industrial Revolution, the sea level has risen about 8 in. and continues to rise about 0.14 in. per year (National Climate Association). IPCC has predicted a sea level rise of 1m. (~3.3 ft.) by the end of this century (O‘Rourke), putting small island nations such as the Maldives and at risk of losing their land, as well as cities in the US such as Miami, New Orleans, and New York. Once again, this number may seem insignificant, but when one considers that approximately 5 million people live within 4 ft. of the high tide areas in the United States; and 1 in 10 persons live in low lying coastal areas around the globe, then the numbers illustrate cause for great concern. An estimated 634 million people will be impacted by rising sea levels (Greenfieldboyce) and 1 billion people could be displaced from their homes by 2050 as a result of climate change (O‘Rourke).

The world is in big trouble, so much trouble that instead of asking how much the sea will rise it is better to ask how fast. The oceans’ rise has been recorded at about a foot per century. Billions of dollars are spent by property owners and the government to fight against costal erosion. Even now the level of the sea rising is increasing at an alarming rate. One day, at this rate, cities will be submerging into the water. People will have to relocate, and finally have some perspective of the animals that are losing their homes due to the glaciers

Thermal expansion and the melting of continental ice sheets and glaciers are raising sea levels. Predictions are complicated with this issue because as the atmosphere absorbs more and more greenhouse gases the faster the melting will occur. When only 1% of the three largest ice bodies on Earth melt, the Greenland ice sheet, the west Antarctic ice sheet, and the east Antarctic ice sheet, there is a sea level rise of 76 cm, which is not including the melt runoff from smaller glaciers and ice sheets all over the world. Now this is simply a rise in the water level, however combining sea level rise with land subsidence will amplify flooding (subsidence is the sinking of continental land which occurs after subduction zone earthquakes, ground water over use, and has many other causes). Every coast line will change, flooding the most populated and dangerous areas, I say dangerous because nuclear power plants are built on the coasts to access sea water for facility cooling and catastrophic damage will add additional poisons and toxic nuclear waste that will travel around the planet. (SkepticalScience). In 2008 there is an estimated 20 million climate refugees, as these events continue it is projected that there will be 200 million climate refugees by the year 2050.

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.

Sea levels are rising all over our planet although coastal regions suffer from it the most. Already, more than 90 coastal communities in the United States are battling chronic flooding, meaning the kind of flooding that’s so unmanageable it prompts people to move away. That number is expected to roughly double to more than 170 communities in less than 20 years. In the 1990s is when this problem was taken into consideration, although by this time sea levels had raised 20 cm over the years.

at a much faster rate. When the Antarctic ice sheets melts, sea levels will most definitely rise

Why are the sea levels rising so fast? They are rising because the water comes from melting glaciers and ice. Additionally, the water is “swollen by thermal expansion of water as the planet warms.” Because of this, the oceans in the world are now about 8 inches higher than they were 100 years ago. Another question the article poses is: “How much higher will they go?” NASA is concerned that what was originally predicted is now too conservative. The Intergovernmental Panel on Climate Change (IPCC) predicted that by the year 2100, sea levels could potentially rise “28 to 98 centimeters… depending on the volumes of greenhouse gases emitted.” However, even if the greenhouse gas emissions become stable and “global warming is limited to no more than

Abstract—Sea level rise due to change in climate is a severe global threat; Flooding, storm surges, and other consequences of the rise in ocean water level have a widespread adverse effects on coastal cities across the globe. Consistent rise in ocean levels have occurred throughout the world for thousands of years. The data from tide gauge observations and global satellite imagery, assisted us to determine the rates and causes of rise in sea-level. On analyzing the data, it affirms the need for long-term reliable observation to estimate accurately the regional changes furthermore to improve our ability to estimate the future changes in ocean levels. Even if the best preventive measures are taken, ocean levels will continue to rise for many decades to come, due to the large time ranges associated with the climatic evolution even if the temperature rise is stabilized. Information from various scientific studies is requried to understand sea level rise (SLR), this review emphasizes the problems and consequences this rise in sea level is creating by projecting the Ocean water levels in the future under the present global conditions.
