Great post...
The melting is happening faster at the North Pole. I'm afraid the planet is going to become bottom-heavy. You know how the Earth is kinda tilted, right? Well, if the bottom gets too heavy with snow, then we're going to lose the tilt! And then say goodbye to major seasons!
Hmm, if the Earth became bottom heavy, wouldn't that cause the Earth to fall? So it would drop out of its orbit and head downward, away from the solar system.

ice at the N Pole doesn't "weigh" any more than the water its covering; now ice on land, thats another story. I wonder what effect a mile of ice on Greenland has on our rotation etc. Probably not much, I guess its really nothing more than a mile high mountain range. But I'd think additional weight at the S Pole would help stabilize us, like a spinning top. Actually its our Moon that stabilizes our tilt, without the Moon we could have wildly changing seasons and "we" may not have ever evolved. But even the Moon doesn't have an equatorial orbit so while it stabilizes us it also causes variation in the tilt, not much, not enough to dramatically affect the evolution of life.
I'd like to know why the Earth has a tilt, it must be the product of an impact(s).

Nobody really knows. Could have been an impact or not. Large impacts arent always the smoking gun. Uranus tilts almost 90 degrees on its side, and its far too large and gaseous to have been tilted by an impact.

Uranus could have gotten its tilt early on its formation before it was massive
this planet X or whatever is supposed to be outside the orbit of Neptune at the moment, right? And it comes around every 3,600 years? then how is it to get into the inner solar system within 3 years? I realize things speed up as they approach the sun and the oort cloud is big, but that just doesn't seem quite right to me, especially as there doesn't seem to have been any talk of extremely fast moving objects in the neighborhood for a while. just a question, I'm sure there's probably some very smart answer.
as for the earth tilt, I offer the moon-creating impact as an answer, and isn't the tilt oscillating?
And please, can we at least include teapots in future space-related doomsday scenarios?

sorry to hear that 
Thats a theory by Zecharia Sitchin, tying the Sumerian "Divine Year" or Sar of 3,600 years to the orbit of "Nibiru".
It wont, and according to the theory the invading planet's closest solar approach (perihelion) is the asteroid belt. But we'll see it long before it gets that close... If it exists.
Combining myth and astronomy, the "creator" or invading planet is preceded by increased long term comet activity. So I hope it dont come around for a long time
Yes, roughly between 24.5 and 22 degrees. But if the Moon impact theory was valid, the Moon should be orbiting the Earth's equator and its off ~ 5 degrees. Plus, the Moon shows evidence of being present when the Earth was last struck by a massive object, the side of the Moon facing us got plastered by debris and locked into that orientation.
I was just watching Naked Science on the Natl Geo channel and they were trying to explain why the Earth has water when it shouldn't by virtue of its close proximity to the sun, ie volatile materials like water vapor were pushed out of the inner solar system by the solar wind to the asteroid belt where they began freezing/solidifying. This is the logical place for a planet to form early and with water.
But some of the asteroids have water, including water matching Earth's water. So now they have a new theory to explain why asteroids with water were hitting the Earth much closer to the Sun. They claim Jupiter's gravity disturbed the inner mini planets sending asteroids from the asteroid belt inward to hit the forming Earth thereby bringing us water. They dont explain how Jupiter formed so fast and got so big, they just make that convenient assumption. Its possible the Earth formed at the asteroid belt and was pushed here by a collision, thats why we have water.

Not really. The asteroid belt exists because Jupiter's gravity prevented any planet from forming there.

so some say, but how did Jupiter form before a planet closer to the sun and closer to the asteroid belt? How did Jupiter get so big? It was a "beneficiary" of the collision at the asteroid belt. The impact released plenty of material for Jupiter to sweep up, not just small chunks of rock that eventually became moons or satellites but gases.
Well who knows about the asteorid belt, it may of had plenty of mass earlier but currently it doesn't have the same mass as the moon(about 1/3rd).
And isn't Earth's wobble due to the creation of the moon? Why something the size of Mars smacked into us?

The lack of material at the asteroid belt is actually a problem for the people who claim its a failed planet, ie a planet that didn't form because of Jupiter's gravity. There should be plenty of debris floating around if a planet never formed there, but if a planet did form there, it would have swept up the loose debris. Now, I dont know if analysts have taken into account all the known cratering on other planets when determining how much debris was in the asteroid belt. But if a collison 4 bya released material it would explain why the planets are so heavily cratered and that material would have to be added to the known asteroids along with a bunch of moons and comets etc. But as I understand it, there still isn't enough debris to form a planet. Of course, the theory says the Earth was at the asteroid belt and was not destroyed by the collision. So there doesn't have to be enough debris at the asteroid belt to form a planet, the planet that was there still exists...here.
The Earth's wobble (precession) is caused by the various gravitational tugs we get, including the Moon. They figure if the Moon formed from the debris of a collision between Earth and something else, the impactor was Mars sized based I suppose on the size of our Moon etc. It was something big, but not big enough to obliterate the proto Earth. But it still was big enough to leave material for a Moon. Oh yeah, another problem with the Jupiter theory is the asteroids dont follow normal orbits, they're inclined when in reality we should find lotsa asteroids on the solar plane.

Jupiter is a gas giant. Jupiter is also far more massive than any terrestrial, including the Earth (which is the largest one in our solar system); the amount of debris which would result from a collision between Earth and a Mars-sized object would have very little effect on Jupiter's mass.

No no no.
That is, yes, geomagnetic reversal happens.
But it is not at all what the Planet X loonies are talking about. Their imagined scenario involves an actual, major and sudden shift in the Earth's rotational axis (to be caused by this invisible planet on an impossible orbit). All of the Earth's crust sliding around so that central Europe becomes the new North Pole, or whatever, and everywhere becomes a different climate zone, and there is mass starvation etc.
These loonies have been at it, in various configurations, for at least a decade; I can quite clearly recall when the apocalypse was certainly coming in May 2003. Google "zetatalk" if you have a lot of time to waste.

FYI, I chase trains.
that's not planet x, its roseanne bar.
There's still the Sun's gravity. At worst, the Earth would dangle underneath the Sun, outside the plane of the rest of the planets.
You do know that debris can be ejected out of its orbit, right?

Oh, I was thinking magnetic poles... Yeah that's a very different matter...
Theoretically possible... but only with a large impact that would likely pulverize the Earth (no more life, no more continents, no starvation). Also, the Moon helps to stabilize Earth's Rotational Axis anyway... so... yeah....
