I have a science question?

My point is to bring to light the blatant lie the leftist global warming nuts keep telling. They claim the polar ice will melt and the ocean levels will rise, and all of our coastal cities will be under water...if we don't sent them all our money and die. Meanwhile obama and al gore both have giant multimillion dollar home...right on the waterfront. 🤷‍♀️

It won’t because I pick out the ice when it softens up and munch on it. Especially in this type of weather.

I'm somewhat reluctant to even bring this up, but there is a theory that we are way overdue for another major ice age, and I don't mean a gradual cooling over several years with the temps eventually reaching a point where we are "uncomfortable" and can no longer grow crops.

The thing that shocked me when I first heard this is that we have proof that this has happened in the past. Every kid who has eve taken a science class knows the story of the woolly Mammoth that was found frozen to death with a flower still in its mouth, but no one ever pointed out how fast or how low the temps would need to drop in order to freeze an animal the size of a Mammoth before it could swallow its last meal.
I can't say how likely this is to happen, but at least the claim is more credible than believing that if we don't somehow turn back the world's "thermostat" by a few fractions of a degree then in a hundred years or so the sea levels are going to rise by so many feet and life as we know it will come to an end due to "global warming".

Archemedes was a smart fellow.

The bouyancy of ice displaces water. As is melts, this bouyancy decreases as the density of frozen ice decreases.

In short, it is the same. However there may be loss due to evaporation so in fact the water level may decrease slightly.

Now alarmists claim if all the ice melts, sea levels rise 270 ft. However that figure is a lot closer to 216 feet. What they fail to mention is that scenario may take well over 1000 years and it does not account for changes.

The world goes through cycles. If we had listened to these same alarmists in the 70s, we would be under polar ice now deep in an ice age.

Realistically the water may rise but one foot won't make the papers. To sell fear we use maximum numbers.

It will not rise; however, after the ice in the glass melts, if more melted ice (water) is added, the glass will over flow. Glaciers are ice formations on land masses. They are not currently in water. As they melt, they will increase the volume of the ocean.

It’s much like snow melting from mountains in the spring that create flooding in rivers, destroying land masses. It’s why many dams have been built. They “protect” human encroachment.

It won't overflow at all, if you can neglect the (very small) thermal expansion of the water as its temperature rises to ambient temperature after the ice melts.

It never will, water expands in its solid form.

From what I remember from my fluid mechanics class in college (engineering major here) the water will not overflow the cup when the ice melts. Nor would the water overflow the land masses if the glaciers melt.

The exact height will remain the same, the mass of ice cubes are already taken into consideration. You might even lose a few drops in a hot environment due to condensation and evaporation.

It won't, of course. Excellent analogy to highlight lie #617 of the global warming agenda.

I believe water has more mass in solid form than in liquid form so the water level would drop.

It never will ice, like at the north pole is less dense than water that's why ice floats

It won`t.

Since I usually start sipping when the water is nice and cold, I have never observed the water level after the ice melts.

However, I could theorize that the glass will never overflow.

Nothing will happen as the water level does not change when floating ice melts. Ice floats because it is less dense (0.9 gm/cc) at 0°C than water (1 gm/cc) with a proportion of its surface below water level as to displace its own weight in water. When ice melts, water produced by the ice will exactly fill the original volume that the frozen water has displaced. The floating ice is already displacing a volume of water equivalent to its mass, therefore no change in level.

Depends, how long will it take for someone to add more water to make it overflow.

Water is one of the odd items where it's solid form is actually larger volume than it's liquid form. So it'll underflow, instead of overflow as the ice melts. As ice takes up more room, which can be proven by throwing a full water bottle in the freezer, and it will destroy the bottle.

From what I can tell, the glass will not overflow because ice takes up more room than water.
With the melting of ice on the surface of the planet, sea levels will rise, because the above sea level ice will flow into the sea, raising the level.

Sitting a full glass of ice water on your Ram

It won’t overflow

Never

I'm thinking water expands as it freezes so when it melts it will take up less space. It shouldn't overflow as long as the ice wasn't sticking up WAAY above the glass to begin with.
