Water Options

[Simon Kirby]

Hot enough for you? While you're sizzling in the heatwave if you get to wondering just how much water there is on the planet then you might be interested to know it's this much (according to the United States Geological Survey)

That's what every drop on earth would look like if it was all collected up into a single giant shpere, every drop in the ocean, in the rivers, in the atmosphere, frozen in the ice caps, and locked up in the ground - all of it.

[Nothing Much]

A bit scary. It seems as if someone had a quiet afternoon and played around with some big numbers.
That David Bowie has a lot to answer for.

For goodness sake don't tell Thames Water that!
Don't give them another excuse!.

In millennia to come, once this planet has been sucked dry of all it's resources and Mars is inhabited by human lifeforms, that is what little humanoids will see through their telescopes when they look up into their sky through the red dust back up at the Old Home.... Except there won't be any green bits....

So the Mid-West USA is going to be hit by the tsunami to end all tsunamis! Call out the National Guard!
Increase security on the President!

Interesting, but a bit like 'if every grain of sand in the whole world was gathered into a ball.....'

What it illustrates for me is quite how thin the ocean layer is - if that ball of water was a nub of butter it would be spread very thinly over the toast of the oceans.

I find it curious to think that life on earth couldn't have evolved without that water, and curious too that water in the atmosphere of extra-solar planets could be an indication of a life-sustaining environment. There's still some water on Mars and there may have been oceans in the past, so while it seems extremely unlikely I wouldn't completely dismiss the possibility that primitive life of some kind could still exist under the ice on Mars.

And if we can see their water, perhaps someone is looking enviously at ours... (cue Jeff Wayne).

The pink sphere on the right is the volume of air on and around Earth.

These are fascinating pictures an imaginative presentation of information that would make little impact if just pitched as numbers. Is there one for oil?

Is there one for oil?

If you are talking about what's left then I would imagine the sphere would not be discernible to the naked eye!
