Only sea ice does that glaciers are mostly on land hence they are not displacing water so yes they would raise sea levels
And icebergs are mostly in the oceans...................
Based on the seasonal rise and fall of temperatures on the continents that contain glaciers, they aren't going to melt any time soon. And if they did, it would be by some cataclysmic disaster that raised the global temperature above freezing for thousands of years to create the total melt down of glaciers.........
69% of this planet is oceans and 31% are land mass. Of that land mass, 30% is covered in deserts where there is no snow.
The North Pole is a floating ice cube so there would be no noticeable rise if it melted entirely.
The average annual temperature of the Antarctic is -47 degrees so it would require a millennium years long rise in temperature by 79 degrees to melt it sufficiently to raise the oceans. Any rise in earth's temperature by 79 degrees would fry every life form on this planet so that ain't gonna happen soon......
