Is CO2 a major component to Global Warming?
It certainly is. CO2 is a proven “greenhouse” gas, and we know for certain that it traps heat reflected off or emanating off of the Earth’s surface and retains heat in the atmosphere that would otherwise be dispersed into space. A 1% change would not make much of a difference, however, but human activity has caused far greater than a 1% change. Think you meant to ask whether was a overall increase in Earth’s atmosphere from 1% CO2 to 2% CO2 would make a difference. The answer there is a big yes. The notion that CO2 “traps” heat is *not* a myth or a misstatement. It absrobs heat energy and re-emits it, and at least some is re-emitted toward the Earth and is then rabsorbed by matter in the lower atmosphere or crust. Over time this feedback loop steadily increases average heat. There are, of course, other greenhouse gasses. The primary one is merely water vapor, but water vapor essentially regulates itself because when the air become suffused, the water vapor falls back to Earth as rain,
