Eli5 water displacement question, I think.

710 views

Ok, so my question is rather dumb and I apologise in advance.

If I have 500ml of warm water, and I place exactly 500ml of ice into said water, when it melts will it make it up to 1L?, and if so why is global warming such an issue because isn’t there more water on earth than there is ice, so wouldn’t it just melt away. (I’m not taking away from the fact global warming I not an issue) I was just making something that needed to cool quick so I put ice in it and it made me curious!!

No, it’ll be around 950 mL.

Ice is less dense than water so while the 500 mL of warm water weighs about 500 grams, the 500 mL of ice is closer to 460 grams

The concern with global warming isn’t that sea ice melts, it’s that glaciers that are currently over land melt

The ice sheets over northern Russia, Canada, Alaska, and Antarctica don’t fully melt and because they’re supported by land they’re not displacing ocean water. But when they melt their water runs down and into the ocean thus raising the sea level
