Radiation which cools the planet is emitted primarily from the atmosphere. A gas will emit far more radiation than a solid, because it has a large, three dimensional emitting surface compared to the two dimensional emitting surface of a solid.
As a result, radiation cools the entire atmosphere uniformly. It is primarily long wave, infrared radiation, which goes around greenhouse gasses, which cools the atmosphere by escaping into space.
The graph below shows temperature decreasing with height in the atmosphere. If there were more radiation escaping into space, the cooling would increase, as indicated by the lower line.

Notice that the cooling effect is greatest at maximum height and very slight near the surface of the earth. This shows that variations in cooling due to variations in radiation have little effect near the surface of the earth.
So even if the temperature of the planet were heating due to increased greenhouse gasses, the result would be almost undetectable near the surface of the earth. How then do climatologists get an increased temperature with their thermometer measurements? They wouldn't, if they were making real measurements. They faked the numbers.
This graph shows that if greenhouse gasses really were heating the atmosphere, there would be very little result near the surface of the earth. Satellite measurements are more reliable, and they show slight variations near the surface of the earth, but this would be due to oceans heating, not greenhouse gasses.
Another important point to be aware of is the role of water vapor. Water vapor is about a hundred times more of a greenhouse gas than carbon dioxide. If greenhouse gasses were really relevant, the large variations in water vapor would be frying and freezing everything, certainly swamping the effects of CO2.
There is a major fraud in the way water vapor is handled. First, the frauds claim that water vapor does not overwhelm the effects of CO2, because water vapor is stable, while CO2 is increasing. The exact opposite occurs. There are massive variations in humidity, which is why humidity is a major part of weather reports. Humidity varies from near zero in dry areas to near saturation in humid areas, while it moves around in varied and unpredictable ways.
Then the frauds have the audacity of claiming that a 0.2°C temperature increase caused by CO2 was multiplied to 0.6°C by water vapor. The slight primary effect by CO2 supposedly increased the holding capacity of the atmosphere for water vapor resulting in more water vapor in the air.
Nature produces massive changes in temperature and holding capacity in the air. Only where there is saturated humidity is holding capacity the determining factor. Seldom, is humidity saturated. There is a large amount of yearly and decadal variation, in addition to daily and monthly variation, in regional and global temperatures and humidity. To claim that a miniscule effect is the only change occurring, and it is dooming mankind, couldn't be a more blatant fraud.
If water vapor is more of a greenhouse gas than CO2, which the frauds admit when they multiply the CO2 effect by a factor of 3 due to water vapor, why would anyone want to exchange CO2 for water vapor in tailpipes and smoke stacks? Why is not water vapor a pollutant endangering the health of mankind and in need of being controlled by the EPA, when it is more of a greenhouse gas and more variable than CO2? No explanation. That's how much objective reality there is in the global warming fraud. You think that's a joke? It's even more of a joke to claim CO2 is dooming mankind.
Perhaps the most obvious fraud of the whole subject is to be attributing the entire climate to the atmosphere, while oceans determine about 98% of climate variation, and in a highly unpredictable way. Oceans are in rivers of motion and mountains of layers of hot and cold; and they vary so much that scientists don't have a clue as to what oceans are doing.
Nature shows that oceans are warming, and as they do so they increase humidity and precipitation everywhere. Where do you get droughts out of that? What nature shows is described on the page titled The Next Ice Age May have been Triggered in 2008.
Frauds switched to using the term "climate change" attempting to indicated that opposites can result from increased carbon dioxide. There is no mechanism for producing opposites. Carbon dioxide cannot move heat from one place to another. It is almost uniformly distributed in the atmosphere.
The only explanation given at the scientific level for opposite effects (droughts and floods; heating and cooling) is that the greenhouse effect is supposed to be more noticeable over the equator than over the poles thus causing a difference. Such an effect was never found. Even if it occurred, it would be so miniscule and so diffuse due to convection spreading the heat around that no differences would be noticed in weather or climate. For scientists to assume they could actually measure or observe a "greenhouse" effect over the equator without it being totally dissipated through convection is incompetence to an extreme.
And then, measured effects show more change near the poles than near the equator. The measured effects are the opposite of predicted effects. The reason is because oceans are heating, not the atmosphere, and they carry heat into cold places such as polar regions.
Sahara Desert turning green
The Sahara Desert is turning green due to increased precipitation as described by National Geographic. Nothing but oceans warming can cause increased precipitation on a large scale. If the atmosphere were heating more than the oceans, less precipitation would occur. Similarly, the center of Antarctica is accumulating more ice due to the increase in precipitation. (described on Oceans) The increase in precipitation shows that oceans are heating, not the atmosphere.
This shows that greenhouse gasses are not heating the atmosphere, because warming reduces precipitation. Fakes claim the opposite saying that since warm air holds more moisture, it will have more moisture in it, which increases precipitation. They are wrong in the same way they are wrong about water vapor amplifying global warming.
Their argument is based on the claim that increased holding capacity for water vapor in the air is the same as increased water vapor in the air. Holding capacity does not determine the amount of water vapor in the air, because seldom is the air saturated. This means the air almost always has unused holding capacity, and something else determines the amount of water vapor in the air.
The number one factor determining the amount of water vapor in the air is ocean temperature. This means the increased precipitation is caused by increased ocean temperature, not greenhouse gasses. The fakes totally ignore the influence of oceans on climate, while measurements are showing more and more evidence of oceans determining the effects of climate.
Addendum: An important undercurrent which is not usually recognized is that there are two types of science that evolvedone correct and one fraudulent. The global warming issue shows how the fraudulent science works.
The fraudulent concept of science evolved in physics due to the extremely abstract and mathematical nature of the subject. Physicists pull mathematics out of thin air and adapt it to purposes related to technology. It's usefulness causes them to assume it is scientific fact. But the math is always a shortcut which can never properly represent the complexities of nature. (See Stephan-Boltzmann Constant.)
That type of science was applied to the subject of global warming by James Hansen, a physicist at NASA and primary driving force for the fraud. He juggles computer models to fit his purpose of global warming alarmism the way physicists juggle math to design a semiconductor.
Math is used in that manner by fraudulent scientists to create an impenetrable wall around the subject which cannot be touched by the infinite complexities of real science aligned upon the laws of nature. Math moves (fake) science into a dark pit of unaccountability, which is exploited by power mongers for unquestionable authority. Extreme examples include relativity, the big bang and energy misdefined, which the public swallows hook, line and sinker, in addition to impenetrable areas such as quantum mechanics.
In other words, promoters of the fraudulent type of science do not relate to math as a tool of science; they relate to it as a replacement for the type of science which they don't do.
Perspective
What should be apparent by now to anyone who follows this subject is that scientists don't have the slightest ability to determine what climate is doing at the present time, let alone the future. None agree with each other on the details of any subject, on either side of the issue.
The best indication of what climate is doing is nature. A major cool-down in the north (in 2008 & 9), with ice reforming over the Arctic Ocean, says something. It says there was a massive loss of heat over the arctic. Canada is experiencing a drought, which indicates an absence of warm ocean water around the Arctic putting water vapor into the air.
Try to find a scientific explanation for these events. There is no indication in the science of the subject that these events have even occurred. A global cool-down is all that is being mentioned. Scientists do not do an analysis of nature for many reasons. First, they get paid to do something other than that. Nowdays, science is assumed to be a quantitative study. Common sense looking is not a quantitative study. So "scientists" calculate and calculate, and they wouldn't notice if the sun disappeared.

Geologist rips Obama's 'new scare report': 'I become more skeptical every year. I am now beginning to conclude that global warming simply does not exist' - June 17, 2009
By Geophysicist Dr. David Deming, associate professor of arts and sciences at the University of Oklahoma who has published numerous peer-reviewed research articles. Excerpt: The new scare report issued by the Obama administration refers (reference list) to the work of Stephen H. Schneider six times. You will recall that Schneider is infamous for telling Discover magazine (October, 1989, p. 45-48) that "we have to offer up scary scenarios, make simplified, dramatic statements, and make little mention of any doubts we might have...each of us has to decide what the right balance is between being effective and being honest." 2. There has been no sea level rise for the past three years. 3. Hurricane, typhoon, and tropical cyclone activity is at a 30-year low. 4. The satellite data (UAH MSU) currently show that mean global temperature is about the same as it was in June of 1979...no, if anything, it is LOWER. [...] Global "warming" is based almost entirely on the record from meteorological stations. Anthony Watt's survey of 1221 weather stations is now 70 percent complete, and shows that an astonishing 69 percent of these stations are likely to have serious errors, due to their being located near heat sources such as asphalt paving, air conditioning vents, etc. After following this subject now since the mid 1980s, I become more skeptical every year. I am now beginning to conclude that global warming simply does not exist.
Increasing Evidence for Cause of Ice Ages
Gary Novak, July 23, 2009
It's beginning to appear that the cause of ice ages is heat accumulating in the oceans. The heat keeps increasing for 10,000 years or more between ice ages. Solar energy would probably stabilize much sooner and stay near the surface, because warm water does not sink easily (Heat always rises.) So the heat apparently comes from within the earth, just as geothermal energy does. Coming from within the earth, it heats the oceans from the bottom up, which means the entire oceans accumulate heat.
Then there appears to be an interaction with Arctic ice. Artic ice constantly melts and refreezes. It was melted a thousand years ago, when the Vikings lived on Greenland. Melting and thawing creates a massive heat loss over the Arctic. This occurred over the past five or ten years. Now the Arctic is extremely cold resulting in record cold everywhere in North America which is affected by Artic air.
When the oceans get hot enough to keep putting much water vapor into the air, while Arctic cold causes it to form snow, the accumulation of snow reflects away solar energy triggering the next ice age. Whether this latest cool-down of the Arctic triggered the next ice age or is just another cycle leading up to it is yet to be determined. See The Next Ice Age May have been Triggered in 2008.
Warmest Ocean Surface, July, 2009
NASA said ocean surface heated a lot, and the air heated a little. How can the air be heating the oceans when the ocean surface heats more than the air.
