Remember when you tried to claim that your plants made it to the cover of High Times?
I thought you guys were "winning"...?

You're defending me.Not a single person on the site is defending your dumb ass, can't take a fucking hint.

I like how the same people come here and try to prove to the same people how much they should be liked. Year after year, after year. Typing up all kinds of intelligent shit thinking that just maybe this will be the post that finally gets them to agree. Winning!!
I'm a fat racist. Never have I tried to prove anything. I'm not lacking in the confidence that would require me to do so.
Carry on, losers.

I'm going to physically place my plants On the cover of a copy of High Times, take a picture, and then go around claiming that "my plants made it to the cover of High Times!"
A meme is conceived... let it proliferate!

Not anymore they don't. Too busy making Muslims feel good about themselves.

Such a shame what NASA has become. They still rock, but from the mission statement to readjustments to purpose, we can do better.
We choose to go to the moon not because it's easy.... so bad ass.
We are going to lead from behind... not so bad ass.

Yep, good thing we don't use chariots. Maybe we could go with "there's nothing wrong with being the caboose, the caboose is vital to the ride".
It's a far cry though comparatively.

I was thinking more in terms of "learn from the other guy's mistakes; let him make them first."
Or: let the competition do all the R&D, then use their own discoveries to best them.

Fair enough. We can be software pirates. Good or bad strategy on developing the atomic bomb? (or just warfare period)
I don't mind sitting on the sidelines watching war in the middle east at all. But if we are going to get involved, I'd prefer we play more than just the tip hoping for sloppy seconds.

Into the Laboratory, it's time to go to work.
Next, let's take a look CO2 from an Atmospheric Physicist's view - straightforward physics that we hope most of you will be able to follow:
What we commonly call "light" is actually electromagnetic radiation, physically no different from radio waves, except of different frequencies and wavelengths. The part we can see is called the visible spectrum. Beyond what we can see in the higher frequencies ( and shorter wavelengths, since they are reciprocal functions ) lies the ultraviolet spectrum. UV light is very penetrating, which is why one could get sunburned on an overcast day. Beyond even that are X-rays, which can penetrate much deeper. On the opposite end of the visible spectrum lies infra-red... which you can't see, but you can easily feel, as anyone who has warmed his hands near a hot stove can testify. It is the infrared portion we commonly refer to as "heat" radiation. And beyond that are the radio and television wavelengths we all know and love.
The sun is very "bright", and its frequency spectrum is generally too short to produce much infrared coming down through the atmosphere. Radiation from the sun penetrates the atmosphere, strikes the earth, and some of it is absorbed and some is reflected. The different bandwidths (colors) of reflected light depend on the material struck, so something green-colored is reflecting the green portion of the visible spectrum and absorbing the rest. This heats up the earth, and that's the first part of the story.
All heated bodies emit radiation in the infrared range. This is called "black body" radiation, because a perfectly black body reflects no visible light but still emits radiation in a specified band of wavelengths. Infrared radiation is of a much longer wavelength, and can be much easier absorbed by certain components in the atmosphere, causing them to also "heat up". The warm air around us is being kept warm partially from black body radiation coming from the earth itself. Another method of warming is by conduction - air coming in contact with the heated soil, rocks, trees, buildings, etc. and being directly warmed by that contact. This may be a bigger factor than we think, but we're not going to attempt to try to determine just how much that might be. We'd have to know the total surface area of every object - down to the smallest blade of grass - there is on our planet. We also need to remind ourselves that there is actually no physical quantity known as "cold". There is only "heat" and "lack of heat".
Let's look at a real result, below - the absorption spectrum for pure carbon dioxide plus an amount of water vapor equal to that in our current atmosphere as the sample and infrared radiation from a black body spectrum as the source. This is part of the so-called "greenhouse effect"
To give you a feeling for how little CO2 there actually is in the atmosphere, let's note that atoms and molecules are very tiny things, and the distances between them are therefore also very small. Physicists like to use a unit of measure called an Angstrom, which is 0.1 of a nano-meter, or a 0.1 billionth of a meter, (i.e. 10^-10 of a meter or 10^-7 of a mm). A molecule like CO2 has a size of around two Angstroms (2 x 10^-7 mm). The density of the gas is 10 to the 24th power number of molecules occupying a space of about 22 liters (i.e. 4.55 x 10^22 molecules per liter) at a pressure of 760mm of mercury and 273 degrees Kelvin (i.e. 32 degrees Fahrenheit or zero degrees Celsius) – called the "standard temperature and pressure". You can almost think of all this as just the normal temperature and pressure around you right now. A simple calculation shows that in a 3-dimensional tetrahedron array, as shown in the diagram below (for the closest possible packing with an equal distance between molecules), the spacing between molecules is approximately 28 Angstroms.

Since at 2 x 10^-7 mm diameter, CO2 is a very tiny molecule, let's magnify the picture by a factor of 10 million, so that we can imagine a CO2 molecule as a 20 mm diameter marble floating in the air. However, CO2 makes up only 380 of each million molecules of air – the rest are a mixture of all the other atmospheric gases and water vapor – i.e. only one in every 2632 molecules is a CO2 molecule. Let’s imagine that all the other molecules are colored blue, and CO2 molecules are colored red. All the marbles making up our model atmosphere are equispaced at 280 mm apart. When mixed evenly into our model atmosphere (which is what the wind does) a bit more simple math shows that our red marbles are equispaced at 3900 mm (i.e. 3.9 meters) apart. In the real atmosphere, at a height of approx. 5500 meters, pressure is halved from what it is at sea level. A bit more simple math shows that at a height of 5500 meters (55 million kilometers in our model – that’s 143 times the distance from earth to the moon!), our 20 mm diameter CO2 marbles are equispaced at 4.9 meters apart. Now you know why CO2 is called a “trace” gas.
This whole picture we have drawn ( with Peter Morgan's help ) illustrates both how little CO2 there is in the atmosphere, and how relatively little of the radiation it is capable of absorbing and "heating" the atmosphere. We know that most of the other IR radiation bands slips through and doesn't get to do any heating at all. (We've all seen the nice IR photographs taken from the space station.) But some scientists such as Dr. Heinz Hug ( I love that guy's name) who specialize in study of this stuff claims that all of the heat in these particular spectra are indeed absorbed in a relatively short distance, so adding more CO2 to the atmosphere can't affect anything at any rate. Other scientists, such as Dr. Roy W. Spencer at NASA - and one of the leading experts in the field of climate science - doesn't completely agree
We've decided to be exceptionally generous to all concerned in the debate and look at the worst-case scenario, where we'll say that all of the available heat in the CO2 absorption spectrum is actually captured. We know that man is responsible for about 3 % of it, so with the simplest of math, we have .03 x .08 = .0024. And remember that 8% figure was actually larger than reality, since the two side peaks don't have much energy to capture.
Man-made CO2 doesn't appear physically capable of absorbing much more than two-thousandths of the radiated heat (IR) passing upward through the atmosphere.
And, if all of the available heat in that spectrum is indeed being captured by the current CO2 levels before leaving the atmosphere, then adding more CO2 to the atmosphere won't matter a bit.
In short, the laws of physics don't seem to allow CO2 it's currently assumed place as a significant "greenhouse gas" based on present concentrations. The other "greenhouse gases" such as methane, nitrous oxide, tetrafluoromethane, hexafluoroethane, sulfur hexafluoride, trifluoromethane, 1,1,1,2-tetrafluoroethane, and 1,1-difluoroethane exist only in extraordinarily smaller amounts and aren't even up for serious discussion by any segment of the scientific community. And, since the other components of the atmosphere (oxygen, nitrogen, and water vapor) aren't materially affected by human activity, the "greenhouse effect" is essentially a totally natural phenomenon, unaffected by human activity. We could repeat the spectral analysis and calculations for Oxygen, or O2 ( The percentage of oxygen in the atmosphere remains exactly the same at all heights up to about 85 km, and is about 20.9% by volume ) and Nitrogen (N2) which is the whopper at 78.1% - but we won't. We'll leave that as your homework problem now that you know how to do it. Just look up the atomic absorption spectra for both, and do the math. You'll discover that Oxygen and Nitrogen aren't even "greenhouse gases", so that leaves the principal greenhouse gas... you guessed it.... Water Vapor. Curiously enough, the UN IPCC reports don't even mention water vapor, since it is technically not a "gas" in the atmosphere. Dr. Roy W. Spencer (Buck's fave) has one of the best comments we've read on this subject:
We can safely ballpark water vapor as being responsible for more than 95% of all the greenhouse effect, with oxygen and nitrogen playing no role and carbon dioxide being relatively insignificant... particularly the even smaller human-produced part.

"Al Gore likes to say that mankind puts 70 million tons of carbon dioxide into the atmosphere every day. What he probably doesn't know is that mother nature puts 24,000 times that amount of our main greenhouse gas -- water vapor -- into the atmosphere every day, and removes about the same amount every day. While this does not 'prove' that global warming is not manmade, it shows that weather systems have by far the greatest control over the Earth's greenhouse effect, which is dominated by water vapor and clouds."
We can safely ballpark water vapor as being responsible for more than 95% of all the greenhouse effect, with oxygen and nitrogen playing no role and carbon dioxide being relatively insignificant... particularly the even smaller human-produced part.
