This is about 10,000 times the amount of water consumed by the United States per day. This is according to madsci.org Now, I can’t find it now, but someone posted a video of a science demonstration here showing that ice melting in a glass will not raise the level of water in the glass. Presumably this was a statement about the predictions of global warming and sea levels.

A comment was made on the original platform (youtube, was it?) that this doesn’t account for ice on land that would melt into the seas. The assertion is that would raise the sea levels catastrophically. But, given that evaporation is increased and the atmosphere can absorb more moisture with increased temperatures, superimposed by the amount of water evaporating daily now, might sea levels not really rise catastrophically? Wouldn’t the increased evaporation condense to rain and be dispersed more uniformly?

For the record, I’m not yet curious enough to make scientific calculations. I’m still at the mental rumination phase…..

I'm not sure what the question is?

We'd see sea levels rise, We'd also see more warm/hot rainforest in more northern latitudes. Very much like how the earth was before the most recent ice age.

Whatever goes up, comes down, including evaporated water. Warmer temps evaporates more water, but most of that water comes right back down, mostly back into the oceans, when the weather cycle cools, or when atmospheric currents carry it over cooler global areas.

There is probably some offset on rising ocean levels, but over all the effect of melting land-based ice more than over-rides it.

(And you're right about ice already floating would not affect ocean levels if it melts. Land-based ice like glaciers is a different story.)

[ETA: just to be clear, I am NOT bought into the whole global warming "crisis". My post was just to explain the hypothetical science.]

I don’t know what the question is but I am thinking sea levels won’t rise from melting ice caps. I’m open to be corrected. But I imagine a glass with ice. The ice is less dense (by about 9%) than the water and that’s why ice floats. 90% of the ice is below the water. Being that 90% of the ice is displacing water and is less dense, when the ice melts, there is less water from the ice that displaced the water so the water level will drop.

The water level will only increase if there is considerably more ice on land and not displacing water than the ice that is currently in the water.

What makes everyone think that glaciers are the norm and not an ice age artifact.

Every day 870 cubic miles of water evaporates from the world’s oceans

It’s not my fault.

It is a closed system in equilibrium.

Anything "man" can do is only a many, many places right of the decimal.

The earth goes through cycles, influenced by that big bright ball 93 million miles from here.

The universe laughs at our hubris.

A melting ice cube floating in water in a glass may not raise the water level, but how about a melting ice cube positioned above the water on something like a small mesh screen? It’s obvious that in that case water would be added to what was in the glass. Large quantities of water in the form of ice are not currently in the oceans, but will be as those glaciers melt.

During the ice ages when much more water was in the form of ice on land the sea levels were much lower than today.

And of course what goes up must sooner or later come down. More water can be held as vapor in warmer air, but that also means that more is available to precipitate out as rain or snow under the right conditions. That also does not mean that precipitation will increase everywhere. Other changing weather patterns affect where it comes down when it does, and precipitation can actually decrease in some areas as a result.

A lake, river, swimming pool or other body of water loses 1/4” of its surface water each day from evaporation.

Con artists like that pimp Al Bore present facts like the OP and then declares an imminent crisis unless we start throwing bundles of cash at him.

As mentioned above, this is all cyclical and has been happening long before any of us were born.

Here’s a distribution of all known surface water in all its forms on the planet. This does not include whatever water thought to be locked up in the mantle (ie inaccessible) theorized to be comparable to what is currently in all the oceans combined. Mind boggling.

A very informative diagram!

Here's an thought: since one of the main contributors to "global warming" is the Sun, why don't we bundle up all the greenie weenies, stick them in one of Elon's rockets, and send them there to investigate? Kill two birds with one stone.

Forgot bottled water,
I have 36 gallons.

Glaciers and rain run off carry silt with it. Slowly causing the oceans to rise.

Stop Continental Erosion!

First, we were all going to die from freezing in the coming ice age because of the pollutants we were putting into the air, reflecting the sunlight away from the planet.

Now we are all going to die because the Earth is warming, and we did that with greenhouse gases.

I am going to say this again, as I have been saying since the 1970.

It's the sun, stupid. Get over yourself

My distrust in global warming and the dire predictions is formed from two points in my life.

The first time I heard about global warming was as a Purdue student in freshman chemistry, and the 60ish year old professor/scientist lecturing that day snootily proclaimed that Indiana would be a physical desert in 20 years not just a cultural desert. Well, it's been 34 years and Indiana is still just a cultural desert

Additionally, I have worked North slope Alaska (i.e. in the Arctic Circle) where some of the so-called global warming evidence is located:

I have had ice Road construction crews working for me and ice Road construction permits depend on ground temperature. Running a low impact vehicle similar to the snow cat used by ski resorts, the crews could compress the snow and drive the lower temperatures into the ground faster enabling us to build the ice road faster. The lesson learned is that snow is a very good insulator and this will become important in the next bullet.

At one point, I had three dozen geotechnical engineers working for me and during that time greatly expanded my knowledge about soil borings, permafrost, and ground temperature trends. In one of the mountain passes, where the haul Road (i.e. the one made famous and ice road truckers) connects deadhorse with Fairbanks was one of the temperature sensors showing the earth's temperature was warming. One of the PhD geotechnical engineers advanced to the next slide of the presentation, and they overlaid depth of snow by year which showed a direct correlation between early and deep snow insulating the ground which reduced ground temperature.

I think my rumination earlier symbolizes the theories advanced by others with the same speculation and the same validity. Ultimately, no one knows. They superimpose their perspective over climate events and run with their interpretation. Calling it truth and settled science is just a mechanism to deflect scrutiny and allow for policy to be imposed. We can measure, record and anticipate, but the environment and earth systems are too complex to diagnose and compel behavior accordingly.

My opinion.

rising sea levels, what can mankind do to influence the sea level?

makes me think of this verse from the Bible

"Fear ye not me? saith the LORD: will ye not tremble at my presence, which have placed the sand for the bound of the sea by a perpetual decree, that it cannot pass it: and though the waves thereof toss themselves, yet can they not prevail; though they roar, yet can they not pass over it?"

pretty much nothing
