Question

Who else thinks that Earth is just gonna end up like Mars?

Answer 1

You can almost depend upon it.  Sooner or later our planets core will cool, the magnetic field it generates will stop and the solar winds will strip the planet of the atmosphere.  The Moon will continue to recede away from us as it does not by 3cm. a year, and eventually will have no effect on tides and the rotation of the Earth.  Without the stabilization effect of the Moon, the poles will begin to wobble and the weather patterns will be totally different.  Life as we know it will cease to exist or will have moved by then.

Answer 2

Or like Venus, depending on how we handle this whole global climate change thing...

Answer 3

Give it a few billion years, and that's exactly what will happen.  As the sun ages, it slowly shrinks, meaning that the earth's orbit will drift further away from the sun.  Eventually, earth will be a frozen waste land.

Fortunately, it'll heat back up when the sun becomes a red giant.  Before the crust melts into a boiling pool of molten rock, that is.

Answer 4

If we quit de-evolving we can whip earth AND mars into submission

terraform that sumbitch, it's an infinite frontier

Answer 5

It's far more likely that the Earth will end up like Venus. The Sun will most certainly NOT shrink when it ages. It will increase in brightness and luminosity over time, thereby raising the temperature here on Earth. Eventually, the oceans will evaporate and create a pressure cooker environment in a billion years or so. By the time the Sun starts to transform into a red giant, life on Earth will have long since been extinguished.

Answer 6

Earth and Mars are actually more similar than most people would think, or at least were very similar at one time.  A very VERY long time ago Mars had a molten iron core just like Earths.  This would have shielded Mars from the electrically charged particles ejected from the sun in the "solar wind" by deflecting these particles from the atmosphere.  However Mars is much smaller than Earth and because of this the molten core dried up which caused the magnetic field to disappear leaving the atmosphere to be stripped away by these particles.  Once this happened the surface temperature dropped to the point where all the surface water froze, and Mars became the lifeless desert as we see it today.  

Eventually Earth's core will dry up too and then the same thing will happen here.  Luckily that day will not be happening anytime soon.

Answer 7

eventually yes, the earth moves closer to the sun every year, it'll be extra-crispy one day, millions of years from now

Answer 8

Probably more like Venus because of the global warming, and greenhouse effect..
