I honestly am confused how humans are responsible for the earth warming up when we've only been putting CO2 in the atmosphere for the last, what, 200 years? 250?
I don't know that I buy that humans are responsible for global warming. Sure we add CO2. But it's not much at all, compared to how much other things add.

The amount of CO2 we are putting into the atmosphere compared to the amount of CO2 being put in there by natural resources is minimal, at best. So short answer: No. The idea that humans are adding enough CO2 to throw off the entire cycle of hot/cold, (because we do have a cycle going on here naturally), is not one I find very convincing.

There is a natural carbon cycle that keeps the natural output of CO2 stable. Basically the amount of CO2 natural resources toss out is around the same amount natural resources like the ocean and vegetation absorb. The majority of the shit we're spewing out does not get absorbed and accumulates, basically throwing it all off balance. That extra amount of CO2 is building all the time. The planet has natural cycles but we've basically sped it up to the hot cycle 46 times faster by the lowest estimates. One could assume that this hot cycle will be drastically worse that it ever would have been since it's not likely we'll be changing our ways anytime soon.
+1 to both of you. I feel like #1 being Global Warming was an absolute cop-out. I'm not saying that we shouldn't take care of Mother Earth but CO2 output shouldn't be the leading advertisement for being eco-friendly in my opinion.
As for what will take us out? Definitely something from space. We have deciding variables in the other instances. Galactic shit? No chance.
