re: Earth has a suprisingly small amount of water compared to other Solar System bodies

They thing is, is they compare everything to how things are on earth. we are but a blip of a blip of a blip of a blip of a i think heard some blip on the radar in this universe.

big world out there with lots of ridiculous stuff.
And i'm not saying these assumptions are wrong, just that it should all be taken with a grain of salt, and there's a lot of uncertainty that we might not even know is an uncertainty.

Of course, and for the most part, scientists admit what they don’t know. They’re not wildly guessing or making simple-Simon inferences.
Might there be an entire moon made up of a compound that doesn’t exist in any meaningful quantity anywhere else in the solar system? Sure. Is that likely? Absolutely not.
Might it be the case that the compound referenced above has the exact same conductivity properties as water, without being water? Sure. Is that likely? Absolutely not.
I get not taking what scientists say as the Gospel, but I think you can go a little further than “a grain of salt”.

So if we created global warming on these planets we could inhabit them?
Do they have fossil fuels and SJWs?

In theory, yes, we could create an atmosphere on Mars through pumping greenhouse gases into the air, but it would not surprisingly take a long time. And it's being said that there's not enough carbon dioxide.

Under pressure
Right now Mars has an atmospheric pressure of about six millibars – tiny compared to the one bar at sea level on Earth. “We would need something like a million ice cubes of carbon dioxide ice that are a kilometre across in order to do get to one bar,” says Jakosky.
At one bar, the temperature would be just above 0°C, allowing liquid water, and thus life, on the surface. The atmosphere wouldn’t be breathable, but humans could get by with breathing masks, not full space suits, and plants could grow freely, slowly building up oxygen over the course of the next few centuries.
But Jakosky and Edwards found that there’s probably only enough carbon dioxide in the Martian polar ice caps, dust and rocks to raise the pressure to 20 millibars at most. So we can’t terraform Mars with existing technology, because there simply isn’t enough carbon dioxide. “It’s not that terraforming itself isn’t possible, it’s just that it’s not as easy as some people are currently saying,” says Jakosky. “We can’t just explode a few nukes over the ice caps.”

They misspelled the word "amount" in the caption. I don't know why I find that so amusing.

All of it? Where does it go after it goes into the toilet? Do people actually think that the water we consume just goes away? The water you drink never returns to the Earth in some fashion?

Do you even evaporation bro?

I do. Where does it go after that? It turns into rain and back into our oceans, lakes, ponds, Houston, etc.

Ice cold planetary water is the best water.

Until they figure out how to create a magnetic field too, not worth the trouble.
