How does global warming affects the changing of the sea level?

Question

how the heat of the earth melt the ice and rises the sea level.

Answer 1

You are correct, the ice is melting which will cause the sea level to rise. But in addition to that, the weather patterns will change and the fresh water of the rain will change also. The salinity of the sea water will change in turn. It is possible that more water will be held in the atmosphere and eventually the sea level will drop again, leaving us without the cooling effect for the ice provided and further damaging the currents that effect our weather patterns and forcing us to withdraw fresh water from undersea sources... round and round we go, where we stop nobody knows.


That's one degree average, meaning some places are up 10. An average temperature change of 2 degrees means die-off of dozens of species of plants and animals starting a chain reaction. 3 degrees puts us in the quantum leap numbers for die-off. Since we are part of a "system", something that happens in one place effects everyone like domino's. If you bulldoze the mountains that force the clouds up to make rain in one place, not only does that place lose it's rain that rain falls somewhere else that isn't likely to be prepared for that rain. Not only will plants and animals die, crops and buildings and jobs and transportation will be effected.

Answer 2

The interesting thing about ocean levels is that when reality is the basis for the calculations the most the ocean will rise if all the ice melted that real scientists think will melt is only a maximum of 18 inches. This is simple to figure out. Due to some fairly obvious facts that most "Warmers" tend to ignore. 1. North Pole ice does not count. It could all melt and the ocean would not rise at all, because N. Pole ice is already floating in the Arctic ocean. 2. South Pole ice does not count either, Why you ask? Because the average temperature over the whole continent of Antarctica is Well below zero degrees F. It would have to get up to 32 degrees F. to begin to melt. It only gets up to 32 degrees on the coast for very brief periods of time during perpetual sunshine of summer. Even the scariest scenario of global warming (Not counting Al Gores fear mongering) tells us that the variation of temperature from Ice Age to Warming periods of the past only fluctuated around 2 or 3 degrees. It is so cold in the winter in Antarctica that salt water waves freeze as they are in motion. You can find pictures of this. Bottom line is Antarctica will stay frozen. 3. what Ice is left? The rest of all the ice in the world is in Glaciers on Greenland mostly and some in Siberia and Northern Canada, and Alaska. This is much less than 10% of the frozen water that is in the world. If it all melted, (won't happen), it would still be like the proverbial drop in the bucket. Why? because the Ocean is so vast. It covers over 2/3rds of the surface of the Earth. It takes a gargantuan amount of water to make it rise even one centimeter. 4. To melt just another 1/4 of the glaciers in Greenland it is estimated the average temperature will have to rise another 1.5 degrees. Over the last Century the temperature only rose approx 1 degree. So if warming continues, (and that is a big IF) over the long term, (We are actually in a cooling trend in the short term) then you are looking at easily decades and most likely more like a century. 5. Predicting the weather 1 week in advance is still fairly inaccurate science. Forecasters rely a lot on guesstimates and are often wrong. So how could you possibly predict what the weather will do 40, 20, or even 10 years from now? the answer is, you can't. You might as well throw darts blindfolded at a thermometer while it is spinning around at 500 rpm. Chances are better you would get it right that way. P.S. Al Gores movie, "an inconvenient truth" had 9 glaring errors in it as determined by a UK court. Most of Europe is having serious doubts about AGW as a result. In America we are sheltered from the truth by a media that is largely in the tank for Liberalism.

Answer 3

Sea level has been rising since the end of the last Ice Age, and the Globe has been Warming since the end of the last Ice Age (on average).

Sea level has NOT suddenly begun rising faster. It actually was rising faster in the 1940s and 50s, but it has slowed down again, and is back to the century average.

Funny thing, facts. They trump theories every time.

Answer 4

Pollution has burnt holes in the ozone layer which melts the polar icecaps which puts extra water in the ocean which therefore "rises the sea level".

The ice melts and things get hotter because more sun can come through the ozone layer.

Another cause is greenhouse gases which turn the Earth into a greenhouse (hot, humid, icky, and as the process speeds up everything dies) therefore temp. rises, ice melts, and sea levels rise.

Answer 5

The extra water goes into the sea causing the level to rise and the PH level to be shifted which affects the entire sea. The coral reefs are slowly depleting due to this and the animals that live in the Arctic might not be able to evolve fast enough to survive.

Answer 6

Sea levels go down. Fill a glass with ice and then fill with water until it overflows the rim. Let the ice melt, the level in the glass will go down.

Answer 7

It just stands to reason that as the ice caps and glaciers melt that the sea levels will rise and the places we jknow as shores now and/or low lying areas will be reclaimed buy the sea.

Answer 8

Since the last glacial retreat that began 10,500 years ago, sea level has risen over 400 feet. You could walk from Alaska to Russia, the outer banks was once an island. And it had nothing to do with greenhouse gases, and all of that water pouring into the oceans did not stop life from prospering.

Answer 9

Morgan is right. The temperature increase will not be even. It will theoretically warm more in the colder areas. So when you go to the artic (in a hundred years), it may be a balmy 37 below zero instead of 40 below.

Answer 10

The temperature has gone up one degree in 100 years. O my God the sky is falling. If there is really global warming why is Al Gore living in a monster house? Why not trade smoke belching coal fired power plants for nuclear plants that belch no smoke and do not contribute to global warming?
