I don't think adding other gases will reduce the amount of radiation carbon dioxide absorbs lol

    But the scary news are always "Carbon dioxide reached 430 parts per million". So I thought instead of reducing the carbon, we could increase the "per million" for the same effect and have no scary news any more!

    It will dilute it and reduce the effect, sorta like reducing the reflectivity of a mirror.

    I don't think so. There's still the same amount of carbon between the earth and space, so it's still going to have the same effect of blocking IR that's moving to escape the earth's climate system.

    If anything the extra gases will simply trap more heat on their own, although probably less so than the CO2 does.

    The concentration matters, not the absolute amount. Spectroscopy confirms this. 1g of CO2 will reflect IR much differently if it’s in 1mL or 1L of volume.

    The volume doesn't change. It's still the same amount of CO2 in the same volume. There's just more of the other gasses in that same volume.

    Well I'm no expert but that does not make sense to me. I don't think CO2 is reflecting IR but rather absorbing it.

    Not sure where I can read more about this to confirm or deny this idea.
