"Now, in what might be the largest scientific fraud ever uncovered, NASA and the NOAA have been caught red-handed altering historical temperature data to produce a "climate change narrative" that defies reality. This finding, originally documented on the Real Science website, is detailed here. We now know that historical temperature data for the continental United States were deliberately altered by NASA and NOAA scientists in a politically-motivated attempt to rewrite history and claim global warming is causing U.S. temperatures to trend upward. The data actually show that we are in a cooling trend, not a warming trend (see charts below). This story is starting to break worldwide right now across the media, with The Telegraph now reporting (1), "NOAA's US Historical Climatology Network (USHCN) has been 'adjusting' its record by replacing real temperatures with data 'fabricated' by computer models."

And this engineer proposes a ship like the Enterprise that could be built in 20 years. "Engineer Thinks We Could Build a Real Starship Enterprise in 20 Years "In Star Trek lore, the first Constitution Class Starship Enterprise will be built by the year 2245. But today, an engineer has proposed — and outlined in meticulous detail – building a full-sized, ion-powered version of the Enterprise complete with 1G of gravity on board, and says it could be done with current technology, within 20 years. “We have the technological reach to build the first generation of the spaceship known as the USS Enterprise – so let’s do it,” writes the curator of the Build The Enterprise website, who goes by the name of BTE Dan. This “Gen1” Enterprise could get to Mars in ninety days, to the Moon in three, and “could hop from planet to planet dropping off robotic probes of all sorts en masse – rovers, special-built planes, and satellites.” http://www.universetoday.com/95099/engin...

    Thanks for all the previous answers to my question but I have more references to a possible correlation between various radio wave frequencies and global warming. According to the French satellite DEMETER project ......, " The Power Line Harmonic Radiation (PLHR) is the ELF and VLF waves radiated by electric power systems at the harmonic frequencies of 50 or 60 Hz. Evidence of PLHR Propagation in the magnetosphere was first observed on ground. However direct observations by satellites are rather rare [6] and shown in few papers " ......... "All the observations indicate that PLHR influences the atmosphere?ionosphere?magnetosphere coupling. On one hand, non linear interactions between electrons and PLHR can participate in the precipitation of electrons from the slot region in the radiation belts, on the other hand, main part of the PLHR energy dissipates in the lower ionosphere and modifies the ionospheric currents. This problem now requires serious attention because the electrical power consumption is always increasing in the world." ........... "All these wave dissipations in the ionosphere could participate to the global warming of the Earth because the change in global temperature increases the number of natural lightning discharges in the atmosphere. " http://www.lpce.cnrs-orleans.fr/www_expe... The websites cites various science papers on man-made and natural (earthquakes) sources of disturbances to the ionosphere or magnetosphere. So my questions remain...is it possible or likely that man-made sources of EM emissions from radio, TV, power lines, etc.. or even an increase in intensity or frequency of earthquakes can cause some global warming? If we dismiss them as a possible source of warming and concentrate on CO2 or GHG- related carbon taxes or cap/trade policies or convert to electric vehicles en masse with the resultant increase in powerlines/electrical energy transmission, how might it affect warming? Are we barking up the wrong tree without knowing the true cause..if any...of AGW? I'd prefer answers with scientific reference sources... pro and con.. or any related climate science links. Many thanks to all that respond.

Now this isn't a HAARP question...I'm just wondering if anyone has any relevant thoughts or research which refers to atmospheric affects from increased use of radio/TV, etc.. How much energy per year is directed into the sky by the use of radio and TV signals or any other devices and how would this affect ozone or precipitation or water vapor levels as the site claims? Do climate models account for increased EM effects? http://broadcast.homestead.com/Introabst...

  • Was the moon closer to earth in the recent past?

    According to Velikovsky, some research suggests the ancient Babylonians and others saw the moon as being nearly as bright and nearly a third larger in reference to the sun. With all the cratering on the moon, I 'm wondering if anyone has ever calculated how much it's orbit was changed due to those impacts. How do we know when that cratering/impacts occurred? "A Brighter Moon Many traditions persist that at some time in the past the Moon was much brighter than it is now, and larger in appearance than the Sun." "In order that the Sun and the Moon should give off comparable light, the Moon must have had an atmosphere with a high albedo (refracting power)(5) or it must have been much closer to the earth. In the latter case the Moon would have appeared larger than the Sun. In fact, the Babylonian astronomers computed the visible diameter of the Sun as only two-thirds of the visible diameter of the Moon, which makes a relation of four to nine for the illuminating surfaces. This measure surprised modern scholars, who are aware of the exactness of the measurements made by the Babylonian astronomers and who reason that during the eclipses one can easily observe the approximate equality of the visible disks.(6) " http://www.varchive.org/itb/brigmoon.htm
