No clouds really fits the description. Clouds are semi transparent to visible light, and even more reflective of infrared light.

Dude, I've linked to NASA's clouds for kids page.

How Do Clouds Affect Earth’s Climate?

The Short Answer:

Clouds play an important role in both warming and cooling our planet. Clouds give us a cooler climate on Earth than we would enjoy without clouds.However, as Earth’s climate warms, we won’t always be able to count on this cooling effect.

So if you're going to make headway into this "no all the scientists are wrong about clouds" line , you're going to need a really good source, because your word sits on the level of someone who has just made the argument "The greenhouse gas impact of 3.3 trillion tonnes of CO2 is trivial beyond accounting, because I can think of another set of gasses that's much heavier .. namely all the gasses on the entire planet".

The similar claim for "greenhouse" gases is completely bullshit

Absolutely not.

It emits what it absorbs and only in 2 very narrow and discreet bands of the IR spectrum.

Let's quantify "very narrow", looking at that earth's emissions graph I keep pointing you to to refute this point.

Looking at it by eye, it covers about 15% of all the Earth's radiative emissions. Is that "very narrow"? Certainly not if you are trying to imply that means "negligible". It's a significant minority of the outgoing IR that CO2 interferes with.

It's bullshit.

Look at the fucking graph. It's not as hard to understand as you're trying to pretend to everyone.

Fewer and fewer people are fooled by this foolish fake-science nonsense.

Oh, the fucking irony!

Really? That's your best argument? You claim the absorbance bands are "very narrow" based on literally no definition of "narrow", and you want to imply there's someone who's not a paid denier who goes "Ooh, all the science I know must be wrong! The band is very narrow!"

How dumb do you think we are?

The industry funded denial was only ever intended to work against the severely uneducated, because the science is nowhere near as difficult to understand as you're trying to pretend.
