Has anyone modeled the effects of using groundwater on earth's temperature? Water vapor is a much much stronger greenhouse gas than CO2. If we're pumping a bunch of water from underground and using it, part of it evaporates into the atmosphere.

Yes I do lots of stuff like that when I’m Bored. The other day I stick batteries in a dogs but and made him a cyborg dog

If you tie tins on a cats tail and put gas on its butt, it will run forever.

I wonder how much of the sea level rise can be attributed to humans pumping water out of the ground? A lot of that water is going to end up in the oceans at some point. Maybe it's not much but I would be interested to know.

If we drink all the water then sea levels won’t rise.

[–] • 0 pt (edited )

none.

the sea isnt rising. at least not in any way we affect it.

human driven environmental change is a communist money making scam.

i mean you can pretend all those people telling you to give them money because the seas are rising are not buying up seafront properties or selling off their carribbean islands all you like that doesnt make them scamming you fake.

97.5% of water is already in the ocean.

Think about that with muh global warming rising sea level bullshit

I am pretty skeptical about climate change in general. However I think the idea of sea levels rising if the temperature in the arctic raises is pretty sound. If you have ice floating in water, a significant portion floats above the water. When the ice melts all that water goes back down and you will see the liquid level rising. You can observe this with a simple glass of ice water.

Note: this is wrong. See ninja tacos post below

Oh wow look at it appears you've never questioned this assumption of yours.

I stand corrected. Well done.

Melting ice on land does increase water level. Greenland and Antarctica are land.

Water level doesn't go up if floating ice melts. It remains exactly the same. If all of the ice in the Arctic melts the ocean level won't change.

Global warming is caused because polar bears started smoking crack

The water ice below sea level is expanded and upon melting that volume remains constant due to the ratio of displacement replaced by water ice above sea level.

Do a test. Fill a glass with water. Add ice cubes right to the top.

Let it melt.

No water will spill over the cups edge.

Muh sea level rise doesn't pass maths or observation

The notion that climate change specifically global warming will be bad thing is dumb. We dont know where the new wet areas will be, but they will happen, we do know that the majority of land in the north hemisphere is empty, and not used because its too cold. If it gets warmer, huge swaths of canada, and russia, will become the new great plains, and the eastern US may turn into a new Amazon. Sure shitholes on the coast will have to be moved a little inland, but the long term gains for humanity could be huge.

It's one of the most precisely predictable things in nature. All you need is a contour map to be able to see where n additional inches of water will inundate.

Sure shitholes on the coast will have to be moved a little inland, but the long term gains for humanity could be huge.

That depends on a lot. If the climate of large flat areas with good soil becomes too arid for reliable agriculture people will starve no matter how much extra land opens up in Canada or Russia. Even if that doesn't happen, the distribution of rainfall and freshwater would certainly be affected. That is also a life or death situation.

2 things, 1) most of the sea ice {north pole} is under water. Ice floats poorly. Only the top 1+5 percent is above water. 2) ice expands. When it melts it shrinks

You can test both of these facts at home with your freezer.

This is fallacious reasoning. Just because 97.5 percent of water is in the oceans already does not mean sea levels can not rise by ice melting. If it became 98 or 98.5 percent, etc. the level would rise.

You should think a little bit yourself before accusing someone of fallacious reasoning. If ice is in water, it's volume is already accounted for in the level of the water because, duh, it's in the water!!!!

OK let's math Mr glowie.

100% ice melt.

About 1000 years in the future

Ave water depth on earth is 2700m deep. Therefore a 2.7% further addition of water is an extra 73m increase in water levels.

Except :

-.7% locked as groundwater lakes etc. Already melted and physically unable to enter the ocean.

This leaves 2% possible.

Except 1.7% is already in the ocean as ice and won't raise Sealevels.

So 1000 years with 100% melt. (not actually possible = 10m rise.

Which explains why after 100 years of muh globalism scare mongering we haven't seen sea level rises.

The ocean is basically already at max height.

What is the greater threat is soil erosion and tectonics.

great arteseian basin underneath Northern Territory, Queensland, New South Wales, South Australia is the largest water collector in the world.

Doesn’t matter. The chip makers re going to steal all the freshwater
