What percent of ice bergs have melted?

Question

im making a global warming film fer skool and i need to know what percent of the earths icebergs have been melted already and how much will sea level rise in the next few years?

Answer 1

due to the polor ice caps melting, the sea level is rising by 10cm every year, and ice only floats due to its dencity

Answer 2

"Images from NASA satellites show that the area of permanent ice cover is contracting at a rate of 9 percent each decade."

Sea level is rising about 3 mm/year.

This is a slow moving disaster, but one which is hard (not impossible) to turn around.  That process will be slow, too.

The person below is correct that melting the Arctic ice cap (which is floating ice) doesn't raise the sea level.  What raises it is melting ice on land (example: Greenland).  Then the water runs down and raises the sea level.  Also, some rise is due to the simple fact that warmer water expands.

Answer 3

Ice bergs can take sometimes two or three years to drift south (or north from the antactic) and melt.  That process hasn't changed, and global warming has had no effect.

  

Why would schools still be teaching about global warming since it's been proven as a lie?  It just hasn't, and isn't, and won't be happening.  Schools shouldn't be teaching fairy tales so should stop with this g/w garbage.

Answer 4

this is a very subtle but important point:

icebergs are already floating.

If they melt THERE IS NO CHANGE TO SEA LEVEL!

Put water in a glass. Put in some ice cubes. Mark the water level. Go away till the ice has melted. What is the difference?

Answer 5

Bob -- you are totally full of yourself.  even if the ice bergs all melted and all the snow and runoff went out to see, that water would spread out and you would see only the runoff as the water works its way out.  you people are idiots.

Answer 6

more than 100%
