Climate Change On The Oceans

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.

Al Gore anticipated Sea levels rising and the Sea levels have been ascending for as far back as century and the pace has just expanded in the previous decade as ice sheets liquefy speedier and water temperatures increment, causing seas to extend. Ocean level changes from 1993– 2006 where, from June 2006 to January 2016, ocean levels expanded around 41.24 millimeters (1.62 inches). From 33.54 millimeters to 74.48 millimeters in a decade and just running up with the greater

The rise of sea levels are projected to increase warmer waters from one and a half to two degrees in Central North Pacific in 2050, 1.9 to 2.6 degrees in Northern Islands, and also two to five degrees in the Caribbean at the end of this century. This rise of temperature decreases the life of ecosystems in the ocean and resulting in less freshwater for

In present day, the ocean is warmer now than it has been in the past 50 years. In the article, " Signs of Climate Change", it says that in 1960 the average ocean tempature change was -.3 degrees but in 2010 the average tempature change in the ocean was .6 degrees. Where I live the tempature is still continuing to rise more and more each year. With warmer ocean tempature comes rising sea level. In present day the sea level has rose by 7 inches in the past 100 years. In 2100 th tempature is around 15 inches higher than it is in present day. Both of these things are causing more tropical storms to happen and is also making the beach less and less

The combination of these and other trends was an estimated average sea-level increase of 1.5mm per year between 1961 and 2003, which reached 2.4mm per year in the decade from 1993 to 2003. The decades prior to this trend showed only minor fluctuations in sea-level, suggesting that the current rate exceeds what could be caused by natural cycles. While the exact impact of rising oceans is difficult to determine, it is certain that the consequences will include some degree of flooding, integration of salt water into water tables, and a loss of land due to coastal erosion and submersion.6

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).

Critically evaluate the extent to which global warming may impact the functioning of the deep ocean thermohaline circulation.

Warming seas and melting ice are the consequences of global warming which is the heating of Earth caused by greenhouse gasses trapped in Earth’s atmosphere. Global warming causes the heating of Earth’s seas, and when the water molecules in these bodies increase in temperature, they thermally expand which causes the sea to rise. The heat is also causing the melting of Earth’s ice sheets, and when the ice turns to water, it causes the sea to rise as well. Note that the water does not rise evenly. The sea level may increase in some areas as it may decrease in other areas. Sea level rise is inevitable because of the greenhouse gasses that are trapped in the atmosphere, they will always increase sea level to some degree. However, the decisions we

Due to the increasing rate of temperature, the ice sheets are melting. This increase the sea levels. Scientists believe that in 2100, oceans get higher to 1-4 feets. States and cities that surround the water will be covered by the water.

The answer is yes. During this quarter we learned a lot about global warming and its disturbing effects on ocean and climate. Ocean currents that are caused by thermohaline circulation are affected by global warming due to glacial melting in Antarctica and Greenland which cause abundant freshwater input into thermohaline circulation and thus mixing of freshwater with saline water causes the current to slow down and even possibly to shut down, for example, ocean current such as Gulf Stream. Likewise, global warming causes tidal range change due to sea level rise, which is caused by the same factor of glacial melting. NOAA suggests that “tidal datums must be updated at least every 20-25 years due to global sea level rise.” According to Doeke

     Now that we are aware that global warming is influencing our world’s oceans, we must look at the affects that it is having. I did not find any positive affects of global warming on the oceans. It is sad to say, but I was left with only the negative. One of the effects that warmer temperatures have on the oceans is that they disrupt the ocean circulation rate (Pearce, 1996). As I previously mentioned, oceans must maintain all of its characteristics properly. Warmer temperatures in the atmosphere affect circulation rates in the oceans. If circulation rates in the oceans are altered, then everything in the oceanic environment becomes changed. The oceanic currents become affected, as well.

Last but not least, global warming has caused the polar ice caps to melt. The melting of the polar ice caps will cause the sea levels to rise all over the world. If the sea levels rise just a metre

The main factors in this climate change are observed to be the increase in temperatures and the resulting acidification of the oceans. The previously mentioned changes and others in the report are readily observable, such as the uptake of anthropogenic carbon since 1750 that has led to the ocean becoming more acidic, with an average decrease in pH of 0.1 units and in some instances blatantly obvious, even to the average layperson. It is difficult to conclude what the rate of change in the future will be and the effects of observed ocean acidification on the marine biosphere.

a. Scientists predict that the ocean will get warmer and the sea level will rise as a result of intensified greenhouse effect. i. Explain the greenhouse effect and how climate change is thought to occur.

One of the most serious effects of global warming, as it continues to intensify, is the increase in the ocean levels. Thermal expansion of the ocean and glacial melting are likely to cause a .5 to 1.5 meter rise in the ocean level by the year 2100. As the ocean level rises and if no protection is provided, many freshwater supplies could be jeopardized. Tens and possibly hundreds of millions of
