Plus, not all of the CO2's re-emission (the mechanism behind the greenhouse effect) radiate back to Earth - a majority of it actually radiates back to space:
Infrared radiation from CO2 and NO, the two most efficient coolants in the thermosphere, re-radiated 95% of that total back into space.

Climate is not just a black-and white system. It's a rather complex, almost chaotic system.

In my defense, I am a computer guy and not a climate scientist.
If we are coming out of an ice age, shouldn't we kind of expect to have rising temperatures?

Now let me add a follow up question:
How come every single climate skeptic always dodges this question, by pointing at irrelevant natural cycles, and only asking questions like yours instead?

If you trust people and fear of questioning them because they are called "experts", then this is your decision. But as for me I prefer investigating if one degree is really that big a deal.

I am just trying to understand this whole thing, and I seem to be shunned every time I bring logical thought into the discussion.

For you and other people who are on the fence or otherwise skeptical:
1) Do you believe CO2 causes heating?
2) Do you believe that CO2 concentration has been increasing?
3) Do you believe sea ice is decreasing?
4) Do you believe the Sun influences the Earth's climate?

How much C02 is normal, and how much it too much? And who makes that decision?

Based on what I have learned it does. But my question is, since we have always had CO2 (dinosaur farts), how much is the right amount? Plants need it. They crave it. And can that change with other factors?

It depends how warm you like your planet. Most of us prefer to keep it as stable as possible to what we've been used to for the last 10,000+ years.

I don't let the kids touch the thermostat. Who get's to control it?

Point is there are alternatives and they really aren't as painful as most people think.

What if we start a massive campaign to reduce our CO2, and then find out that plants are dying and we are getting too cold? If the AGW side is right, then we have the ability to basically control global climate over an entire planet. I don't let the kids touch the thermostat. Who get's to control it?
Thinking in those terms, makes me thing if we have control, or even impact, it's very little. (but again, only my thoughts)
