Maybe you should try to answer my question.

Sense humans were not around at the time, what caused these warming period? Also, how do we know for sure that this same mysterious mechanism that caused the warming periods in the past is not to blame for the current warming period?

You're preaching to the choir.
I also "cite" the fact that it takes hundreds of years for the ocean to catch up to the "global warming", the fact that we are coming out of an ice age, the fact that CO2 has been MUCH higher in the past during one of the coldest periods in all of history, reject the fallacious fear-mongering of what global warming do, etc.
But there is no denying that humans have not had some sort of impact. They estimate it at a very small percentage....but that can literally be the difference.

Well "global warming" isn't really up for debate at this point. The question is how much impact humans actually have.

The earth has natural cycles of cooling and warming. There have been a lot more than just 4 ice ages.
The major difference this time is the rate at which it's happening. In the past it took thousands or even tens of thousands of years for climate swings to occur. This time it's happening in only a couple hundred.

Not if you are a Republican. 😉

So, you are saying that global warming is natural, and not caused by humans, however, human activity is accelerating the process?

That's not 100% accurate. While the main shifts in climate may be over tens of thousands of years, there are much smaller fluctuations in climate that take place over only a few hundred to a few thousand years.

This I agree with and I don't know why the media have latched onto the CO2 issue as opposed to other greenhouse gases. Methane, for example, while in a much lesser amount is a far more potent greenhouse gas than CO2....This is called the global warming potential. It means that for every ton of methane, it has the effect of 25 tons of CO2. For every ton of Nitrous Oxide it is the equivalent of 298 tons of carbon.

The key word here is "smaller". They also tend to be localized, not global and are usually caused by large volcanic eruptions celestial object strikes, or major shifts in ocean currents.
I think we have helped it along a little bit, but i also think it is the natural evolution of the planet, there have been warmings and coolings in the past and this is just one of those instances. At any rate it doesn't matter casue in 2 - 3 billion years, the sun will expand and cook us and may go nova and or our galaxy will collide with adromada and we will be killed that way. or the universe will rip itself apart or collapes in on itself this is assuming we are still here. 🙂

Closer to 4-5 billion years when it stops being a "main-sequence star."

No it won't. You're thinking of supernova. Our sun isn't nearly massive enough to go supernova. And a nova is a something that happens in a binary or more star system with one being a white dwarf...the accretion of hydrogen reaches a critical mass and then goes boom...just like a nuclear weapon. Seriously.

That's "Andromeda". And that will occur about 3 billion years from now. And the distances between each star are so great that it is unlikly that anything will happen to our sun and solar system. It is far more likely that nothing will happen to the solar system than something happening period.
In fact, if I'm not mistaken, the outer edges of our galaxies will touch and pass through each other, but, largely, we will barely touch.

No.

Possible but extreeeeemely unlikely. This is referring to the universe's "many" lifes in which the physics the governed the universe caused it to collapse in on itself and form anew, with a different set of physics. Also, I think you're referring to unstable vacuums on a cosmic scale.
On another note, there could be stars out there made completely from strange quark matter! Very very weird, indeed.

We won't be. Not even close. But our progeny will be. 🙂
