Ah, a closed mind. Not selling shit, you really don't give a rat's ass about the truth. If you did, you would google, optimum CO2 for plant growth. If the science really mattered, you would google hazardous levels of CO2 (OSHA or other health sites). If you cared about the truth, you would google a lot of other sites I would recommend for you to check out and draw your own conclusions.
You would ponder this example, let's say the atmosphere as a percentage is represented by the 100,000 seat Kyle Stadium in Texas (1/10th of a million, kind of scientific). Of those 100,000 sports fans, 79,000 are nitrogen. 20,000 are oxygen. 900 are argon. Let's do a simple tally to see where we are since those are really BIG numbers, that's 99,900 ( I'll wait while you get your calculator to make sure I'm not lying to you). Okay, checked me out? Good with that so far? The remaining gases are known as trace gases, of which 40 (400 ppm) is CO2. In the static atmosphere theory of Climate Change- 35 of those sports fans are good, but the 5 additional Texans are destroying the planet. 5 out of 100,000. 50 ppm.
Physics says that CO2 doesn't only reflect heat in one direction. If it reflects heat at all, it would reflect an equal amount of heat from the sun back into space- that's a real live scientific term called "equilibrium". Not as fun as the goosestepping march you are doing now, but hey, the facts can sometimes get in the way of a really good time.
Now let me present another case study. A few years back people were horrified by the amount of global warming induced glacial melting that revealed primordial forests underneath them. A sure sign we are racing headlong into catastrophe.
Don't you think to ask, "How warm was it when the forest grew 10,000 years ago before it got covered by a glacier?"
