Glaciers Holding Back Sea-Level Rise Are Showing Signs of Collapse

a reply to: kenzohattori69

That is a great example of sea ice here is an example for the ice shelf.

Completely fill a glass with ice then fill the remainder of the glass till it is 2/3 of the way up with water. Let the ice melt and observe the water level.

a reply to: Grimpachi Yup, it's the ice on land we have to worry about.

Then you have failed to understand what ice sheet is.

Can you imagine the scale of the ice sheets that slid across the great plains of the US?

I'd also be wondering what the effect of ice weight is on the overall structure of the sphere of the Earth. Imagine all of that ice suddenly going liquid and your perspective might just change.


The melting of the polar ice caps would cause me concern if there was only going to be bare rock left exposed to solar radiation. Now that ... that would cause a problem.

If you think that can break off a glacier and fall in the ocean I have a bridge to sell you.

You were wrong Greathouse, Just admit it. I seen pieces break off of a Glacier from a Boat up in Alaska with my very own eyes. I respect how you dig your claws in and fight to defend yourself, but it happens to us all sometimes bro.

Thank you for answering. Too many people here just want to argue.

I think we are doomed, if people cant even agree on the term Ice sheet or Ice shelf.

Just to remind people....you know all that fresh water that falls from the sky, called rain, sleet, hail, drizzle, snow?

Well, ALL of it comes from evaporated water vapour originating in the Ocean, the water cycle.

Imagine how much water vapour is taken out of the ocean and sits in our atmosphere, not to mention all the subterranean water locked in the crust, huge oceans and rivers of it.

Not to mention all living creatures (including 6 billion humans) are composed mostly of H20.

You may like this link then because you can enter sea level rise for coastal states from 1 to 10 feet to see what the effects would be.
sea level
That is just a little over 3 meters and I read that if all the ice melted it would be around 90 meters. As you will see from the link 3 meters would be catastrophic I can't even come up with the words if it reached 90 meters.

I've come to realize, I am in one of those " do you want to be right or do you want to be happy situations" I choose happy.

a reply to: Greathouse

You know, I can relate. Good choice my friend.

Changed my mind I want to be right.

I rarely do this but I think occasionally people can only understand things if they watch a YouTube video.

Listen to the scientist explaining Ice shelves he says they are floating. As soon as something is floating in water Archimedes law of volume is in effect.




I have also seen ice break off of glaciers and fall into the ocean to create icebergs. The problem is that's not what I'm talking about.





I have no idea why I originally replied with that stupid saying I have never believed it once in my life. Lol

You kill me Greathouse, you're a piece of work my friend, But I like it!

And just think about it???????

I have only done one rant thread on this site!!


ROTF!!!!!!

Glaciers aren't "holding back sea level rise". This would indicate that the Glaciers are holding back some massive lake of water.

This description is inaccurate. Glacier melt will CAUSE a lot of sea level rise, but we need to be more accurate in our posts descriptions.

a reply to: Greathouse

You do realize a significant portion icebergs are above the water and they are slightly buoyant due to trapped gasses and such. While the volume of water below the water line fall under Archimedes's eureka concept, the volume of the ice above the water line does not and will add to the total volume of the water mass.

Notice how ice cubes observed in cup are about flush with the water line and no ice is left above the water line, that analogy is null and void in terms of ice causing sea level ice.

I am surprised have not jumped all over the FACT that water is unique in terms freezes making it buoyant in water(aq), which contradicts the general trend of warm air/water rising and cold air/water sinking. This means that in a cup of water as the ice melts the water level lowers slightly as a result of the now liquid H20 being heavier in liquid form than in solid form.

That is exactly what I've been saying, that is all I have been saying.

Just to make it explicitly clear to everyone the statement highlighted is all I've been addressing. Don't care about gases, don't care about freshwater versus saltwater, don't care if it's connected to land and I don't care if it's holding water back on land.

This whole issue started on page 1 when some clown with 15 exclamationpoints told me that a ice shelf does not displace any the key word there is any I'll say it one more time so you guys get it any...,water.




I don't believe it's humanly possible to make my position any clearer than the above paragraph.





Edit: this reply was totally meant in fun I am not trying to insult anyone. I was only trying to be humorous and very very specific.

No.. these glaciers arent all in and under water already.

And op both these glaciers are from southern hemisphere.

At the end of the day some volume is being added to the oceans, but it might be like adding a cup of water to an already full bathtub. It's all the ice that is not touching any water, it's all on land, when that ice is added back into the ocean, then it's like adding a 5 gallon bucket full of water to a swimming pool.

Don't try to deny an increase of total volume.

a reply to: Grimpachi

Wow! I think that's Leviathan at 1:51..

Simply amazing footage

Let's have some fun!

Small scale: Freeze a few 5 gallon buckets of water and put them in your pool. Let the water melt. The water level in your pool won't change.

Smallest scale: put some ice cubes in your glass, then fill the glass right up to the top with water, and let it set. As the ice cubes melt, the cup won't runneth over... and might actually lower due to air dissolved in the ice cubes.
