Ice bergs melt when they absorb heat (thermal energy) from sea water and from the air. Direct sunlight is largely reflected off them.
The icebergs are melting because of heat trapped in our atmosphere by global warming is being pushed by global wind patterns to the poles. This warm weather causes the melting. When winter comes, the glaciers will expand. In a number of cases, the amount that melts in the summer is significantly more than the expansion in the winter.
Icebergs melt mainly due to the warm water temperature and air temperature surrounding them. When the temperatures rise, the ice begins to melt and break apart. The process is accelerated by factors such as sunlight and ocean currents.
An ice block melts by becoming a bit warmer than the freezing point of water (usually around 0 degrees Celsius, depending on atmospheric pressure).
Ice typically melts from the outside inward when it contacts warmer air, liquid, or other solids from which it can siphon off thermal energy.
The actual melting (and slight evaporation of the melted water) actually cools the ice block, and slows the melting of the rest of the block.

Why don't the icebergs in Antarctica melt?
Actually, they do melt and they move around.
Salt melts ice so why doesn't the icebergs melt in the ocean?
They do. It just a slow process.
What happens to icebergs after they have broken off a glacier or ice sheet?
After breaking off a glacier or ice sheet, icebergs can float in the ocean and drift with ocean currents. They may eventually melt, break apart further, or run aground. Some icebergs may also pose a hazard to ships navigating in the area.
What do you mean by melting of icebergs?
Melting of icebergs refers to the process of icebergs turning from solid ice into liquid water due to rising temperatures. As the temperatures warm, the icebergs lose mass and volume as they melt, contributing to rising sea levels. This phenomenon is a result of climate change and poses a threat to coastal communities and ecosystems.
When will the icebergs melt completely?
Certainly when the sun turns into a red giant. Prior to that no one can say with certainty.
Why don't the icebergs in Antarctica melt?
Actually, they do melt and they move around.
Do large icebergs ever melt?
Yes, large icebergs can melt due to warmer temperatures, sun exposure, and contact with warmer ocean water. As they melt, icebergs can change shape and size, eventually breaking apart or melting completely.
How cold does the ozone layer have to be to so icebergs dont melt?
The temp of the ozone layer has no affect on icebergs.
How far north do icebergs come in Antarctica?
Icebergs float north until they melt completely.
Why is a polar bear threatend?
Due to global warming, the icebergs are melting. If the icebergs melt, the ploar bears will become extinct due to the fact that many of them live on icebergs.
What is the plural of iceberg?
The plural of ice is ices. As in "eat your ices before they melt".
Should you melt icebergs?
I don't think you and I have much choice in the matter. They melt on their own as the move to warmer waters.
What is the only fresh water part of an ocean?
Icebergs are the only freshwater part of an ocean. When icebergs melt, it results in a decrease in the salinity of ocean water.
What are some commercial uses of icebergs?
I am not sure that anybody actually does it, but I read a proposal to tug icebergs to hot dry places and melt them down for a fresh water supply.
What events would most likely cause a new glacier in north America?
melt of icebergs
Salt melts ice so why doesn't the icebergs melt in the ocean?
They do. It just a slow process.
If icebergs melt in the north of the Arctic Circle how will this influence ocean levels?
Ocean levels will rise.
