Simply put- if you melt the polar ice caps, ocean levels rise, more water surface to evaporate, more moisture in the atmosphere - more rain,, well you get the idea.
But is there enough water to fill in most valleys, and rivers causing an "island" type landscape rather than the large land masses we see today?

And would that be such a bad thing, a warmer wetter climate with a lot less people?

Boy we have some smart ones out here today- let's see 1st ice floating on water when melted will raise the over WATER level but the overall mass will not change. And try to grasp this if you can,, ice is WHITE (relfects heat) water is BLUE (absorbs heat)
Next, when talking about reducing the population by 75% that would more than likley include me, my mom and yes my kids. Nobody wants to die, but we ALL do eventually.

Okay Tomcat,, done, as the ice melted and its mass added to that of the water in the glass the level increased very slightly. My next experiment involved setting an ice cube in a small puddle of water on a table, as the ice melted the puddle, to my astotishment and delight the puddle grew much larger.
the earth is not a bottomless ocean, it's surface is about 3/4 covered by a relativley thin layer of ocean, the rest is they dry land you and I live on.
Don't bother replying, yahoo will kick us both of for "chatting" besides by question has already be answered (very well) by intelligent people.

we keep hearing from the alarmists that ocean levels are going to rise dramatically in the next 100 years, as much as 25-30 feet according to some. however they forget that when water freezes it expands, not contracts. also the large majority of ice is actually under water, thus when it melts the water level wont change. we also have many valleys that are below sea level, and many inland seas and lakes, and rivers, as well as underground caverns that will fill with water. so will sea levels rise if all the ice on the planet melts? yes it will. how much? difficult to calculate because we dont know where all the ice is, and where all the resulting liquid will go. sea levels will rise, but no where near the 25 feet some say that it will. more like 5-10 feet at most. most of florida will be under water, as well as much of the gulf coast. the west coast beaches will disappear, and new york city will resemble venice italy.

If you melt the Northern polar icecap it will raise sea level exactly 0.0 inches. It is already floating in water. The continent of Antarctica (south pole) has lost no glacial mass that occupies land. Only the Ice shelf that was floating already. So there has been no sea level rise associated with the poles melting. The continent of Antarctica continues to get colder, so there is currently no indication that it is anywhere close to melting as result of global warming.
So.... no, I don't get the idea.
Hey Landerscot or (Mr. Wizard) whichever you prefer, before you completely make a fool out of yourself, why don't you half fill a glass with ice, then fill it to the rim with water. Report back after the ice melts your findings of just how much water overflowed.
And try to grasp this, water is clear, it only looks blue for the same reason the sky does. But I will keep that a secret for now.
"as the ice melted and its mass added to that of the water in the glass the level increased very slightly"
you contradicted your first attempt to explain this.
The mass did not change, and the volume did not change, you were wrong, it happens. Large amounts of polar Ice melt and refreeze every year and sea level does not change because of it.
As far as Mr. B's answer, sea level would increase by about 20-30 feet alone if greenland melted. And if Antarctica melted sealevel would raise an additional 180-200 feet. We know where the ice is and how much there is. Also the Geologic record tells a lot of where sealevel used to be before Antarctica was located at the south pole. Some of the great ancient inland seas currently located miles under ground (now onshore), during the permian, jurrasic and cretaceous periods layed down huge deposits of oil and gas when sea levels were much higher than today.
It's just a hunch, but I don't think you are going to select my answer as the best.

It seems likely that higher temperatures would result in more evaporation and so more rainfall. But that would not cover the continents and turn them into island groups. It would just make more runoff.But the runoff will run off quickly enough. Now melting of the Antarctic and Greenland ice sheets would raise sea level enough to flood many coastal areas, making the continents a little smaller. But they would still not be reduced to island groups. There just isn't enough ice to melt to raise sea level enough to do that.

No it's not, stop worrying already. You ask if it would be such a bad thing if there were a lot less people because of it. Well would you be ok with being one of the first to volunteer to be selected for drowning or how about someone you love or care about, hmmmmm? Yeah I thought so, just as long as it's someone else.
Who really cares about something that even if there were a chance of it happening (which it's not) is not going to happen in your lifetime or your offspring's life span. lol

Not the entire earth; just coastal areas and islands. There have been times in the ancient past when the ice caps did not exist and there were still land masses present.

No, if the ice caps all melted it would raise water levels about one foot.

so you'd enjoy having people die so you can have a better life?
how selfish.
i thought only conservatives had a lock on that.
i tell you what.
why don't YOU put your money where your mouth is...
just put yourself in the 75% class that needs to leave the earth to save it?

I WATCHED ON DISCOVERY CHANNEL LAST WEEK THAT THE OCEAN IS ALREADY RISING, I THINK 1-2" PER YEAR AT THE PRESENT RATE.
MANY HOMES WHERE I LIVE ARE ALREADY MOVING FUTHER BACK BECAUSE THE OCEAN WATER IS ALREADY TOO CLOSE.
SLOWLY THE RIVERS WILL GET WIDER AND LESS PEOPLE, ANIMALS AND PLANTS WILL LIVE.
IT IS BELIEVED THAT IN MANY, MANY YEARS THAT THE PLANET WILL BE UNDER WATER AGAIN JUST LIKE THE ICE AGE.
