I don't like people ****ing on my boots and telling me it's raining. I
like to do my own research. That's why I'm a scientist. I keep
hearing that CO2 is a greenhouse gas and it's increasing. I checked
on the spectrographic analysis and found that CO2 barely retains more
IR than Nitrogen. Nitrogen is 70% of the atmosphere, CO2 is 400ppm.


This signature is now the ultimate
power in the universe

Atmospheric Nitrogen (N2) is pretty much transparent to IR.

Bzzt! Wrong answer. It's not. Show me where you got this
information. I'm willing to check this out. BTW, N2 is 70% of the
stuff you breathe and CO2 is 400ppm. For those of you who don't like
to do the math, you hire math majors like me to do it for you. N2 is
700,000ppm while CO2 is 400 ppm. Which one is worse?

1. Nitrogen is nearly EIGHTY percent of the atmosphere.

2. Nitrogen is essentially NOT a greenhouse gas:

"Certain gases in the atmosphere have the property of absorbing
infrared radiation. Oxygen and nitrogen the major gases in the
atmosphere do not have this property."

"This ability to absorb and re-emit infrared energy is what makes CO2
an effective heat-trapping greenhouse gas. Not all gas molecules are
able to absorb IR radiation. For example, nitrogen (N2) and oxygen
(O2), which make up more than 90% of Earth's atmosphere, do not absorb
infrared photons. CO2 molecules can vibrate in ways that simpler
nitrogen and oxygen molecules cannot, which allows CO2 molecules to
capture the IR photons."

Oh yeah. There's different ways of vibrating. And that causes them
to absorb IR. And how does 400ppm let them absorb more IR than the
other 900,000ppm?

I've provided my cites...

....let's see yours.

"While the dominant gases of the atmosphere (nitrogen and oxygen) are
transparent to infrared, the so-called greenhouse gasses, primarily
water vapor (H2O), CO2, and methane (CH4), absorb some of the infrared
radiation."

Actually H2O absorbs much more IR than CO2.
