As the world warms as a result of the increasing level of atmospheric carbon dioxide, so the ocean water warms. As water warms it expands, causing global sea levels to rise. Another cause of rising sea levels is the melting of glaciers and ice caps, releasing water into the ocean. Overall, sea levels have risen 20 centimetres in the last century, and are now predicted to rise by 90 to 150 centimetres during the twenty-first century.
What else can I help you with?
How does the rise in sea level support the theory of global warming?
If sea levels are rising this can be caused by two things:Extra water added to the oceans. This can only come from land ice melting.Ocean water expanding as it gets warmer.We know that sea levels are rising because our satellites measure this. This therefore supports the theory of global warming.
What possible social effects on Bangladesh could come from rising sea levels?
The people of Bangladesh may have to come into India.
How do rising sea levels create islands?
When the sea levels rise the sand goes up to the top of the water and it just creates a island. Sorry if this did not help your question.
What is the role of ozone depletion in the rising of sea levels?
There is no connection between reduced ozone and rising sea levels.Rising sea levels are being caused by the melting of land ice (Greenland and Antarctica, as well as glaciers) and the expansion of water as the oceans become warmer.
How does rising heat affect sea levels?
Heat makes most things expand, and water is no exception. So rising temperatures in the ocean means that the water expands. The only place to go is up, so sea levels rise. This is not counting the melting glaciers and ice caps.
What are the threats against the Sydney Opera House?
rising sea levels. There is a threat posed where the sydney opera house could sink because of the rising sea levels. And to stop the rising sea levels is to stop global warming, which, we all know, is very hard.
Could you solve the problem of rising sea levels by wiping out all sea life?
Rising sea levels are not the cause of sea life. In fact, some types of plankton absorb CO2 from the water, and in turn this means that global warming is slowed, and so the ice caps don't melt so quickly, and so sea levels don't rise so much...
Is sea level currently rising?
yes. The melting of the polar caps adds more liquid water to the oceans, increasing sea water levels all over the world.
What is being done about the rising sea levels?
nothing!
Why does sea level have to do with precipitation?
precipitation equals rain. As when sea water evaporates clouds form eventually leading to rain fall refilling the sea with the previously evaporated water. But not all rain water returns to the sea which is how the sea level changes due to precipitation.
Is the greenhouse effect increasing sea levels?
The natural greenhouse effect is not raising sea levels, but the enhanced (or accelerated) greenhouse effect which is causing global warming, is. The warmer atmosphere is melting glaciers and expanding the water in the oceans, so sea levels are rising.
What can we do to stop the rising sea levels?
To stop rising sea levels, we can reduce greenhouse gas emissions, protect and restore coastal ecosystems, and adapt infrastructure to be more resilient to sea level rise.
