How Long Will The Earth Have Oceans For?
« on: 15/03/2006 18:44:44 »
Someone here said that we are losing water fast. So how much a year? And does the earth have a tail? How long will the waters cover the sea beds for?

...as far as I understand Bren, the Earth will have oceans until the sun boils them away in a few billion years.

If they are indeed losing their water content..where is the water going ?..evaporating into space maybe ?

Who what when?

What you do speaks so loudly that I cannot hear what you say.

I echo the who, what, when?
We are loosing a small amount of water, or more precisely hydrogen, when water molecules in the upper atmosphere dissociate. However, the mantle is still degassing, so that, if anything, the volume of water is increasing.

Increases in solar output will lead to a runaway greenhouse effect on the Earth in between one and two billion years time.

In 2 billion years the earth will be 3 billion centimeter's further away from the sun, OK not much but it may make a slight difference.

How far is 3 billion centimeter's,would it make any  difference to pur climate if the earth today was 3 billion centimeters further away from the sun:)

I'm not sure either Michael though it's a very good thread and I can see how Bren (Titanscape) may have got that idea from it, but unless I missed it, the thread does not specifically state that the Earth is losing water, and at a fast rate.


What I'm also interested in is this Earths ' tail ' that Bren is asking about.


Has anyone heard of this ?...and does it wag ?

There is a tail in the Earth's magnetosphere as a result of interaction with the solar wind.

I'll check soon but Venus has a tail from losing CO2 and stuff from it's upper atmosphere due to solar wind, like a comet.
