'Global Warming' Greenhouse Theory Disproved 100 Years Ago
[Ediotr's Note: The massively funded propaganda campaign to convince the entire world that "Global Warming" is a product of human 'carbon emission' pollution is currently at an all time high plateau, while ironically, the physical evidence that Global Warming is an utter hoax is found on local TV news stations in all but the warmest tropical regions. Cold temperature and snowfall records are being broken from the northern latitudes of Canada to the southern latitudes of Kansas while at the same time, we see yet another repeat on public TV of Nova's well-funded 'documentary' on Global Warming hosted by actor Matt Damon, star of the 'Bourne Connection' films. If I had even one tenth of the production funding that went into that 2 hour propaganda fest and had access to the same public TV outlets accessed by propaganda factories like Frontline or Nova, I-or anyone else who still has a brain-could demolish the entire scaffolding upon which every plank of the Global Warming hoax rests.
The most annoying thing to overcome is the massive IGNORANCE of the American public when it comes to any significant knowledge about the government's role in weather manipulation. The FACT that our Illuminated New World Order government is responsible for CREATING
and jacking up hurricanes, tornadoes, droughts, tsunamis, earthquakes and floods with known and DOCUMENTED technologies like HAARP is apparently unknown to the mass of humanity, who continue to accept rank 'scientific' rubbish from the Al Gore Academy of Brainwashing.
The earth is a LIVING being which tries to compensate and offset the ARTIFICIAL manipulation --by the NWO--of its weather systems and NATURAL climatological cycles. When the NWO uses chemtrails and HAARP to manipulate the ionosphere and jet streams to create drought conditions in Australia and southern California, more rain or snow is produced in another part of the world to try to compensate and re-balance the natural exchange of moisture between atmosphere and land. It's so obvious, a child can see it. Please America, start thinking and stop buying into well-funded and ubiquitously available hype. .....Ken Adachi]

Original Title: Greenhouse Theory Disproved a Century Ago
The claim that carbon dioxide (CO2) can increase air temperatures by "trapping" infrared radiation (IR) ignores the fact that in 1909 physicist R.W. Wood disproved the popular 19th Century thesis that greenhouses stayed warm by trapping IR. Unfortunately, many people who claim to be scientists are unaware of Wood's experiment which was originally published in the Philosophical magazine , 1909, vol 17, p319-320.
Wood was an expert on IR. His accomplishments included inventing both IR and UV (ultraviolet) photography. Wood constructed two identical small greenhouses. The description implies the type of structure a gardener would refer to as a "coldframe" rather than a building a person could walk into. He lined the interior with black cardboard which would absorb radiation and convert it to heat which would heat the air through conduction. The cardboard would also produce radiation. He covered one greenhouse with a sheet of transparent rock salt and the other with a sheet of glass. The glass would block IR and the rock salt would allow it to pass. During the first run of the experiment the rock salt greenhouse heated faster due to IR from the sun entering it but not the glass greenhouse. He then set up another pane of glass to filter the IR from the sun before the light reached the greenhouses. The result from this run was that the greenhouses both heated to about 50 C with less than a degree difference between the two. Wood didn't indicate which was warmer or whether there was any difference in the thermal conductivity between the glass sheet and the rock salt. A slight difference in the amount of heat transfered through the sheets by conduction could explain such a minor difference in temperature.
The two sheets probably didn't conduct heat at the same rate. The experiment conclusively demonstrates that greenhouses heat up and stay warm by confining heated air rather than by trapping IR. If trapping IR in an enclosed space doesn't cause higher air temperature than CO2 in the atmosphere cannot cause higher air temperatures.
The heated air in the greenhouses couldn't rise higher than the sheets that covered the tops of the greenhouses. Heated air outside is free to rise allowing colder air to fall to the ground. Atmospheric CO2 is even less likely to function as a barrier to IR or reflect it back to reheat the ground or water than the sheet of glass in Wood's greenhouse. The blackened cardboard in Wood's greenhouses was a very good radiator of IR as is typical of black substances. The water that covers 70% of earth's surface is a very poor radiator and produces only limited amounts of IR as is typical of transparent substances. Water releases heat through evaporation rather than radiation.
The glass sheet provided a solid barrier to IR. Atmospheric CO2 is widely dispersed comprising less than 400 parts per million in the atmosphere. Trapping IR with CO2 would be like trying to confine mice with a chain link fence. Glass reflects a wider spectrum of IR than interacts with CO2. The glass sheets reflected IR back toward the floor of the greenhouse. CO2 doesn't reflect IR.
At the time of Wood's experiment, it was believed that CO2 and other gas molecules became hotter after absorbing IR. Four years later Niels Bohr reported his discovery that the absorption of specific wavelengths of light didn't cause gas atoms/molecules to become hotter. Instead, the absorption of specific wavelengths of light caused the electrons in an atom/molecule to move to a higher energy state. After absorption of light of a specific wavelength an atom couldn't absorb additional radiation of that wavelength without first emitting light of that wavelength. (Philosophical Magazine Series 6, Volume 26 July 1913, p. 1-25)
Unlike the glass which reflects IR back where it comes from, CO2 molecules emit IR up and sideways as well as down. In the time interval between absorbing and reemitting radiation, CO2 molecules allow IR to pass them by. Glass continuously reflects IR. Those who claim that CO2 molecules in the atmosphere can cause heating by trapping IR have yet to provide any empirical scientific evidence to prove such a physical process exists. The experiment by R.W. Wood demonstrates that even a highly reflective covering cannot cause heating by trapping IR in a confined space. There is no way CO2, which at best only affects a small portion of the IR produced by earth's surface, can heat the atmosphere by trapping IR. Contrary to the lie repeated in news stories about climate, science doesn't say that CO2 is causing higher temperatures by trapping IR. Empirical science indicates that no such process exists in this physical universe.
