How does global warming affect oceans?

Answer 1

A:

1. Polar sea ice is melting. The fabled North-West Passage may soon be accessible for shipping, one of the few potential benefits of global warming.
2. Sea levels rose by 20 centimetres during the twentieth century and are now predicted to rise by between 90 and 150 centimetres in the present century, depending on our success in limiting our carbon emissions. This will in turn have a serious effect on the oceans' littoral zones.
3. Because of the higher atmospheric carbon dioxide concentrations, surface ocean waters are now 25 per cent more acidic than in pre-industrial times. this will affect corals and creatures that rely on creating calcium-based shells.

A:Global warming increases the earths temperature. by doing so the polar ice caps cannot withstand this heat and obviously melt. this turns the once solid ice into water/ocean. therefore more sea, higher sea levels less earth more ocean

A:Global warming causes the ocean temperature to rise and consequently causes the water to expand. This is a contributing factor to rising sea levels. Another contributing factor is the melting of glacial ice and the polar ice caps, again as the result of global warming. Sea levels rose approximately 20 centimetres during the twentieth century and, because global average temperatures are rising at an exponential rate, levels are predicted to rise by a further 90 to 150 centimetres over the twenty-first century.

In some areas the mangroves will be unable to move inland, or will not adapt quickly enough, so for this reason and other impacts on the littoral zone, fish breeding grounds would be devastated.

Also some low lying areas would be flooded like Parts of Florida and Louisiana are some of the many impacted from global warming if this continues

A:Ice sheets will melt which will potentially raise seal levels significantly and cause coastal flooding

Because of the greenhouse effect trapping and retaining heat, the overall temperature of the Earth rises by a sliver every year or so. This excess heat, when factored in, is an out of the ordinary amount as compared to previous years. This heat can melt ice, raising sea levels. The heat and greenhouse gases also pose threats to ocean wildlife.

Answer 2

Global warming melts the ice caps of the wirls, putting cold water and ice into the oceans which changes the currents, meaning that a warm current gets re directed to a cold part of the ocean and vice verca. meaning it will happen the opposite way next time caus ethats what happens
