I think the guy is try to explain something called 'precession'. This is the 'wobble' of the Earth axis. He's just not very good in astronomy.
anyway, precession is like the motion a spinning top makes. If you were, for example, to chart the path of the north point of the axis on that spinning top, it would trace out a circle (which is an ellipse with a single focal and equal radius).
The Earth is spinning in a similar manner... being the axis is not fixed. The Earth's little circle takes about 26,000 years to complete one rotation. It's still spinning at one revolution per 24 hours and completing one revolution around the Sun in about 356.4 days... but, it is also wobbling at a rate of one revolution per 26,000 years.
...
That being said... we won't see the seasons flip (Summer in December, Winter in July for another 12,000 years... not 4 as OLS predicts) due to precession. We will see noted changes in our weather in about 3,000 years.
Any of the changes in our weather today and in the coming years will be due to changes in our atmosphere, not celestrial motion.
And OLS also brought up the Permian Extinction that occurred 250 million years ago. The Earth was a completely different planet back then and events on the surface impacted the atmosphere... the Siberian Earth fart that killed off about 95% of all life on the planet back then... again, due to events on the surface, not from the movement of the planets.
You're talking about the polar shift. Maybe thats what he is talking about indeed. I've heard our next biggest chance for one is between now and 2012.

Are you talking about the reversal in the Earh's magnetic field? I understand at the Earth's natural process swaps the North and South magnetic fields... where you compass will point South, instead of North. The actual axis does not flip... only the magnetic fields, again, due to events occuring on and within the planet, not the celestrial environment.
In the period of the shift, the magnetic fields that protect the planet will be in disarray. The good thing... we will be able to witness Auroras throughout the planet. The bad news, solar radiation that is normally deflected away by these protective fields will bombard the surface. Life will die, but is is not all life on Earth. The planet will survive... and so will some of us. But, not from barricading ourselves in a compound in the desert... it'll be evolutionary changes what will allow us (and other forms of life) to survive.
Hopefully, from there... we will have figured out that shit like War and racism have no place in our lives... that we are all basically the same... and just want to live happy lives.
Or maybe Nature has another species in mind to take over the reigns... possibly the bees or the ants. Let's just hope that they do not create their God in their image and take sole claim of Him.

Hail, Hail!!!
Do you understand how the seasons work? I think your confusing your knowledge with some other info. There might be slight variations in the Earths orbit over thousands of year, but every 2nd grader knows the Earth orbit around the sun takes one year. If it took thousands of years our seasons would last hundreds of years..
i didn't know i was addressing second graders so let me try to give you an example. on i believe august 27th; mars was the closest to the earth as it will be until another century (approximately). although we orbit around the sun; our orbit in space in relation to the other planets is something completely different. on august 27th; it appeared like we had 2 moons. if you were correct; that would happen every year. the same can be proven with eclipses. if our orbit is set as you say; why do eclipses occure at different times?

Because those planets and the moon have their own orbits and they take different amounts of time to complete them...?
Don't try and rework the science know as Astronomy, it is one of the oldest disaplines and it doesn't need an armchair scientist putting in his 2C.
If you have a scientific link to prove it, like you said you did, then post.
