Essay On Sea Level
Sea levels can be defined as the average surface level for oceans around the world, these have been rising since the beginning of the 20th century. Sea level rise is mostly caused by global warming and thermal expansion. When water heats up, it expands slightly; when it is scaled up to large bodies of water like oceans, the change can be drastic. This heating of the ocean is created by human activity, mostly by the emission of heat-trapping gases. These have increased global temperature by 1.4º F since the 1880s. According to National Geographic, sea levels have been rising 3.5 millimeters annually since 1990.
Sea levels have been changing for the last three million years, but they first started to rise alarmingly during 1993, according to

Oceans are getting warmer mostly because of global warming, which is directly related to human activity. Heat-trapping gases such as carbon dioxide and smoke from burning fossil fuels are the main cause for this global warming. Since 1840, the levels of carbon dioxide have increased roughly 35 percent, this gas gets trapped in the atmosphere and later released into the ocean. This allows ocean waters to expand because of the movement of molecules.
With the rise of sea levels, come numerous consequences. One of them is the contamination of agricultural land and crops. When the ocean reaches land, its pH is different from the land’s, this causes contamination. Infected grounds cannot be harvested in. Nowadays, the ocean is also polluted from the trash humans leave behind. Garbage also has an effect on agricultural areas, which can lead to the production of less crops.
Other species can be affected by sea levels as well. Animals like shorebirds and sea turtles, which live on the beach, could have their homes flooded by rising shores. This is especially important for endangered species who can’t afford to lose any offspring. Their nests can be swept away by the ocean, leaving them in an environment where it is difficult to survive. For shorebirds, the rising sea could make them abandon their eggs and lead to their
Florida Keys Ecosystems
1315 Words | 6 PagesThe loss of land from sea level rise will also cause the population to fall and we can expect the carrying capacity to reach limits. As global temperatures increase by 2.5 Celsius above pre-industrial levels and sea level rise at about 12-37cm, we are expecting to see remaining land area in the keys to decline from 80% to 30%. The loss of the surrounding populations in the Florida Keys is contributing to low economic growth, which provides conservation funding for the Florida Keys. These socio-economic changes would restrict our conservation budgets for the Florida Keys. We can counter these events with good conservation management, strong community support and resilience efforts.

661 Words | 3 PagesWhat also has been rising is the acidity levels in the ocean, and you might think "oh this is because people take out water from the ocean and just put the extra salt back" but not quite, scienceandpublicpolicy.org states that "The pH of average ocean surface water is 8.1 and has only decreased 0.1 since the beginning of the industrial revolution (neutral is pH 7, acid is below pH 7)", so the acidity level in the ocean hasn 't risen that much since the beginning of the industrial era due to the pH only decreasing by 0.1 which is not as much as you 'd have
Arctic Animals And Climate Change Essay
766 Words | 4 PagesArctic ice reflects 80 percent of the sunlight back into space. As sea ice melts there will be more sunlight hit the ocean which increase the temperature of the ocean and cause raise of sea level. Satellite observations show that Arctic sea ice concentrations have significantly decreased over the last 25 years. Submarine observations also suggest that the Arctic ice pack has thinned dramatically in the last 20 to 30 years. As the sea ice melts the sea level increase.

Informative Essay: Natural Causes Of Global Warming
1008 Words | 5 PagesNow another natural cause of global warming is the rising of the seas. The biggest reason for sea level rising is that global warming is causing the air to be warmer and that 's causing glaciers and ice-caps to melt. Sea level rise would affect about 11 out of the 15 biggest cities in the world. The reason this is happening because gases are being released into the atmosphere which is causing the temperatures to rise, which causes the seas to rise. Sea level rising means more money that we have to spend for people living on the coastlines because coastal populations are growing and people are crowding into coastal areas and that area could be underwater in a few years if sea levels keep rising how they have been.
