July 4, 2009, Earth Aphelion
July 4, 2009, Earth Aphelion
Earth Perihelion is the date on which the earth is closest to the sun. That date changes from year to year. The last Earth Perihelion was January 4, 2009. On that date the radiant energy that the earth received from the Sun was greater than on any other day of the year. It was a good day. Earth Aphelion is the date on which earth is farthest from the Sun. Today, July 4, 2009 is earth aphelion. Today the amount of radiant energy that the earth receives from the Sun is less than on any other day of the year. REPOST: Let's do some high school math shall we. At Earth Aphelion the earth is at a distance of 1.0167103335 astronomical units, AU from the Sun. See: http://en.wikipedia.org/wiki/Earth At Earth Perihelion the earth is at a distance of 0.9832898912 AU from the Sun. Radiance follows an inverse square law. This can be extremely dramatic if you do flash photography. Under an inverse square law radiance drops off by a factor of four if you double the distance from the light source. Hence, in flash photography objects in the background appear to be in the dark. The ratio of the two distances above is 1.033988392. Taking the square and then the inverse we get 0.9353382 That means that during the course of a whole year the radiance that the earth receives from the Sun varies by ~6.5%. Compa http://en.wikipedia.org/wiki/Solar_c...Solar_constant "Solar constant" "It is measured by satellite to be roughly 1366 watts per square meter (W/m^2), though this fluctuates by about 6.9% during a year (from 1412 W/m^2 in early January to 1321 W/m^2 in early July) due to the earth's varying distance from the Sun, and typically by much less than one part per thousand from day to day." Those who are challenged by high school math, like Al Gore (a high school failure), GISS NASA chief James E. Hansen (a computer programmer), Barack Obama (JD in black liberation studies), should ask themselves how can a "Solar constant" that varies by 90 W/m^2 over the course of a year, be called a constant? What ****ing nonsense. Climatology is a ship of fools. Now the real troubling thing is that people who have shown no proficiency in high school math rule the UN, the US government and the IPCC. Some of them even write readable articles in Wikipedia that may be of little note. Never the less it is worthwhile to check some numbers given by people who can not do high school math. Please read: http://en.wikipedia.org/wiki/Image:R...e-forcings.svg If you are willing to believe the work of people who cannot do high school math you can read the graph that says that the radiative forcing for all the CO2 that is in the atmosphere right now, 380 ppm is only 1.5 W/m^2. The so called greenhouse effect, 1.5 W/m^2 in total, is a triviality compared to 90 W/m^2. $100 billions has been spent studying putative small increments in a number which is trivially small, even if you do believe in the work of monkeys. Our leaders cannot do high school math. We are ruled by monkeys. We are ****ed. We're doomed.

Oh ****, $100 billions has been spent pandering to legions of heat seeking weasels and now $2 trillions is to be spent remediating a nonproblem that is less serious (by an order of magnitude) that the problem of the annual variation of the earth-Sun distance. This craziness could have been avoided if high school math proficiency had been made a prerequisite for service in high office as had been advocated by John F. Kennedy.
