/// (You can guess at what I was going to say to that):1rotfl::1rotfl::1rotfl:

The OP is obviously correct. The response that had me rolling in the aisles was the guy who said the OP was wrong because frozen water expands. That's true -- and if frozen water didn't sink it would cause the water level to go DOWN when the ice melts!

Here are the facts. The OP's experiment (which is performed millions of times every year in science classes all over the world) proves that the entire Northern ice cap could melt and it would not effect sea levels one iota -- except for Greenland, whose ice is not floating.

Antarctica is a different situation. If it melted, sea levels would rise 200 feet. But since the temperature of the entire continent never gets close to 32 degrees (most of it is around -50 for most of the year), you're going to need a lot more than the 2-5 degree warming that the alarmists are predicting. I don't think even Greta Thunberg is dumb enough to predict an 80 degree rise in temperature at the South Pole 100 years from now!

In fact, even the most pessimistic predictions for the next 100 years only predict about 20" of sea level rise, worst case, and most of that comes from Greenland melting (which happened as recently as 1000 years ago). I could give you a link, but if you actually think Florida is at risk, you need to do the research yourself.

Consider this -- 25% of the entire nation of Holland sits on land that is WAY more than 20" below sea level!

I bet in the next hundred years, if we quit worrying and start thinking of practical (rather than political) solutions, we can probably come up with something to keep Miami from getting its feet wet that doesn't involve condemning the entire 3rd world to perpetual poverty, or mowing down entire states for solar panels and windmills.

Hey, I just had a thought! Two words -- floating docks!

Florida’s bedrock is porous limestone estimated to be several hundred to several thousand feet deep a dike wouldn’t work.

Right. But a LOT of the ice on this planet is not IN THE WATER. Using your drinking glass experiment ... when the ice was ADDED to the water, did it not rise? Of course it did. Now, the same will happen when ice at the polar caps as well as glacial ice (not currently in the water) is ADDED to the water as it melts ... the water level WILL RISE.

Truth. Unfortunately, about glaciers cover about 11% percent of Earth's land area so when (IF) they melt, that will be water added.

doesn't matter where it's located......

I agree 100% but too simple for climate change deniers to grasp.

Try this experiment fill your glass with water and place a screen over the top and put your ice cubes on the screen. Once they have melted see how the water level has changed. You may be surprised it has risen.

Glaciers are on land and are receding my example. Icebergs are in the water your example. The icebergs break off from the glaciers increasing the volume the more icebergs the greater the volume.

///

All that is true----but it's just the how, not the why

The why is that glaciers melt, (slowly), because the Earth is warming. DOH.

But the Earth has been warming for the last 20,000 years. Before that it cooled for 45, 000 years, and before that, etc. etc.

And all that happened without any help whatsoever from our Neanderthal and Cro Magnon ancestors. So who are the real "climate change deniers"?

Fact:

Two shots of gin in a glass.

Four ice cubes.

Mark the combined level on the side of the glass.

Watch, over the next half hour...............the combined level goes down.

In Fact: the glass is completely empty.

:D

Plate tectonics will have more of an effect on coastal areas than glacial melt.

At one time almost all of Florida was under water. Millions of years of coral and other sealife died and deposited matter that created the limestone. Other geologic events caused that Florida land mass to apparently rise above the sea level. It could have been due to the weight of the receding glaciers. It could have been movement of the magma well below the Earth's crust.

There are mountains in Italy that are made of white marble high above sea level by hundreds and thousands of feet. Marble is produced when limestone is subjected to pressure and heat. Plate tectonics had something to do with creating those marble mountains; that's where Cararra is mined.

We humans cannot conceive of the time-frames it takes for all these changes to the Earth.

Man caused? Pollution, yes. Sea level rise and fall? Less so.

But yes, the climate is changing, but many, many factors contribute to this.

We'll do much better when we all have a better understanding of geology rather than politics.

Water level
 

Sorry, there will be a slight but measurable reduction in the water level since ice is less dense than water and contracts 9% by volume when it melts. That's why ice floats in water.

Great. In fact this entire stream is great. Me? I think I learned a lot of facts…..or opinions. Thank you to all who shared their thoughts

Agree, which is what I had posted. However, to be technically correct we have to account for the volume of ice above the water line. Therefore, we need to modify the experiment to put the ice at the bottom of the glass, cover it with a screen and then add water. Then we would find a slight drop in the level. But again, this has nothing to do with ice over land melting.

Tell that to all the coastal areas throughout the world and small islands that are disappearing. Clueless!

This has been explained in other posts. The ice floats, but part of it is above the water line, so when it melts, the water level is essentially the same as it was before it melts.

Here's a new science experiment. A Gallon of Water weighs 8.34 lbs. Drink a gallon of water and then weigh yourself to see if you weigh 8+ lbs. more. Next consider the displacement of water when an object is placed in / on the water. The water increase could be caused by all the ships we've placed in the oceans some of which are as large as icebergs. If you think I don't know what I'm talking about your absolutely right. I just make stuff up as I go along.

Try this little experiment.

One the first hole today, fill a big swig with ice and then top off with favorite beverage. Make sure you finish before third hole. I guarantee you will have to stop at next porta potti to remove the excess water.

Could we all agree to disagree with all the disagreements on here?

Why????? This is, after all, TOTV :1rotfl::1rotfl::1rotfl:

I am nut sure but think I will disagree with that.

I agree with you:1rotfl::1rotfl::1rotfl:

Finally someone got it right. The amount of water on the planet has never changed. Sea levels have been much higher and lower. Many scientists believe hat some changes are due to the suns 22 year cycles not human involvement.

and
 

So if there is a HUGE amount of water on the mountains and land what happens to the ocean when it melts

It runs off into the oceans and ocean levels rise. Over the next 25,000 years. Then we cool again, it snows, forms glaciers and more ice at the poles, and NYC will once again, for the 12th time or more, be under 2 miles of ice in 70,000 years. Anyone who thinks this will happen in our lifetimes, such as one prominent individual who wrote a book and had a movie made , is an idiot. Or has a lot of $$$$ to make by pushing this lie.

You might as well. Everyone else is, but just doesn't admit it.

A bunch of guys who flunked 6th Grade Science, debating Global Warming?

Ice Cubes melt and take up the same volume? Scientists are confused about why "hot water freezes faster"? (Look up Mpemba effect.) The oceans aren't rising, the continents are sinking?

Global Warming/Climate Change is a political phenomena and anyone with a whit of common sense knows that.

Trying to apply a modicum of common sense to the arguments, is similar to trying to cure the shanks or the yips, by putting coins in your left pocket.

Exactly, that’s why ice floats. If H2O was like most molecules, it would become more dense and be bad news for fish, because it would sink. I’m not sure where this thread is going, but recall the “experts” all told us we would freeze to death due to the coming ice age when we were kids. Do you think Obama would have bought a beachfront mansion if this global warming was real. It’s all fear mongering for power.

OK with me. What are we disagreeing on?

Some who gets it. Now fill that glass with water and put the ice cubes in. Have paper towels ready. The ice that is melting is from the land.
Note all the glaciers that have receded...what is left behind?..dry land.

Didn't a politician once say he wanted to remove our military base(s) on Guam because he feared by adding more tanks, jeeps etc the island may tip over or sink?

You would think, but there are nights that the responsibility is so great that I can not sleep.

Anyone who wants to sell in anticipation of the rising seas, I will give you .30 on the dollar for your home.

Rep. Hank Johnson is a Democrat from Georgia. I think that explains everything.

Hank Johnson Worries Guam Could "Capsize" After Marine Buildup - CBS News

Why?

I disagree with your implied disagreement of my agreement :1rotfl::1rotfl::1rotfl:

Actually no
 

1. Take a bottle of beer, for example. Put it in the freezer. It will “explode” before long. Frozen water takes up more space than liquid water.

2. Much of the ice caps is on land, not in the water.

Very interesting to finally get a thread based on real-life technical data, although there were probably few who understood. Pure science, folks.

Was not implied but not sure what we are talking about now so that is probably a good thing.
