Nope. I've seen them done by kids, adults in well lit rooms. No curtains!
Exactly, in well lit rooms, ... indoors ... not using the sun to act as the sun.
This is where you and other leftists stupidly allow other people to totally manipulate you, e.g. bend you over furniture and ream you up the azz repeatedly. All one must do to get you to believe that pencils write with ink, is to concoct a demonstration in which a pen is used to represent "the pencil." After writing with the pen for a minute, a simple pointing to the page full of ink and you are convinced that pencils write with ink. After all, it was demonstrated right before your very eyes with the pencil fully represented by a pen. You'll then rush to post the video of the demonstration on internet fora. Similarly, to get you to believe that the atmosphere behaves as though it receives only a narrow frequency band from the sun (and not the full spectrum of EM) is to use a heat lamp to "represent" the sun. It is breathtakingly hilarious the way you fall for the cheesiest crap. Y O U - A C T U A L L Y - F E L L - F O R - I T ! Like I said, it is a parlor trick designed to fool stupid people ... and you are the target audience.
I didn't post a video using the sun because ...
... you don't have one.
Its the infrared light that radiates from surfaces on the earth.
The issue is that you don't know what constitutes the surface of the earth. What you believe is the "surface" is just a part of the earth, and you are not considering the rest. You have to consider all of the earth when you are discussing earth as a black body.
Oh, so you are totally mistaken. This is part of the reason for your extreme confusion.
your questions and comments prove, unequivocally, that you do not understand the science of the matter.
Give it up. You don't get to declare what I don't know. You have to show that I have made an error, and you haven't shown any errors on my part because 1. I haven't made any, and 2. you are scientifically illiterate and wouldn't know how to even discern any errors. All the people who tell you what to believe lie to you. You're in a rough predicament, and I pity you.
There doesn't need to be additional energy.
Yes, there absolutely
must be additional energy. No body of matter, anywhere, ever spontaneously increases in temperature without additional energy. Yes, additional energy is required.
There just needs to be a scenario where the existing energy is being handled differently.
Incorrect. If you are claiming an increase in temperature, you absolutely must account for the additional energy that is causing that increase in temperature. I know, I know, science makes it simply impossible for you to violate physics. Science is an ashsole that way.
Nope. CO2 is an inert compound that doesn't do anything. CO2 does not have any of the magical superpowers that you church ascribes to it. I hate to burst your bubble but your religion's dogma is nothing but malicious disinformation.
It absorbs the infrared light, which become heat.
Nope. Don't be surprised that you arguments aren't getting any better. You still don't know what heat is. Are you as thoroughly embarrassed as you should be? As long as you get it wrong, you'll be getting it all wrong. You have no hope until you learn what heat is. My recommendation is to write everything that you want to say avoiding the word "heat." It's not needed anyway. However, as long as you are using that term incorrectly, your entire argument is rendered null and void.
I do feel sorry for you. Really.
Most of the earth's atmosphere does not interact with infrared light,
All substances absorb IR. You are a science denier, and that is putting your arguments on a seriously downward trend.
so the infrared light, that radiates from the earth, escapes into space. As the amount of CO2 in the earth's atmosphere increases, less and less of the infrared light escapes.
Nope. The earth is in equilibrium. Whatever quantity of solar energy is absorbed by the earth, exactly that quantity is radiated into space.
A huge violation of physics is the notion that the earth will somehow radiate differently with the same quantity of energy from the sun.
