Is Global warming means the end of some of the world cities near the low line coasts?

Question

How soon can we see that?

Answer 1

maybe yes and maybe no.

The idea of the sea rising has a lot of traction because we have good evidence that during the ice ages the sea level was lower. So much water was trapped, that entire continents were covered with ice, as much as a mile thick. So you might think that if the polar ice further melted it could have the reverse effect of making sea level rise.

There are 2 problems with this hypothesis. First, most of the current polar ice, including antarctica, is sea borne. That is, the oceans have already displaced the weight of that ice at its current level. Think of it this way, if you have ice cubes in a drink, what will happen to the water level when the cubes melt. [hint: it stays the same]. Second, as temperatures rise, it is more likely that water will be taken up in the atmosphere as humidity. This would then have the effect of putting more water into the precipitation cycle over land. This is not likely to cause a noticable lowering of sea level but it will counter other effects.

If you saw the movie "water world", that just won't happen ever. Most of the worlds population lives within a days walk of the ocean, so any variation will have an impact, but most likely catastrophic is not an appropriate term to apply.

Answer 2

Yes! It does mean that. As to how soon will depend on a lot of factors-like if we can slow it down or not, etc. Sea levels are rising as we speak but at a very slow pace.The effects from this creating major problems will start to show in the next 30-40 yrs. plus or minus 20 or 30.

Answer 3

I would like to wish all the global warm....umm, I mean climate change, believers a very happy End of the World Day. Ten years ago, Al Gore said that by January of 2016, we would all be toast. I celebrated this morning by scraping the ice of my car windows. How about you?

Answer 4

Yes!

That's why I think that it is pointless to resurrect
New Orleans.

Why rebuild a city that is already below sea level
when the sea level is rising?
