Be my guest.using the same graphic what do you change to have the
geographical axis line up with the Solar radiation/Orbital shadow (SR/ OS) boundary while keeping rotational orientation fixed to Polaris - http://www.astronomy.org/programs/se...flashlight.gif The modification to Copernican reasoning based on the pseudo-dynamic of variable axial tilt is now far more important than the Keplerian orbital refinement,specifically in order to split global climate from hemispherical weather patterns (seasons).With all the grave concerns about climate,the unusual situation is that we do not even have an accurate explanation for the seasons and that is probably the only conclusion that can be drawn at present. To alter the SR/OS boundary is an enormous challenge in itself therefore to make variable axial tilt align with the SR/OS boundary at the Equinoxes is a waste of time even if it still is proposed as a pseudo-dynamic. Who wants to help humanity understand the difference between global climate and hemispherical weather patterns with the help of modern imaging and the correct astronomical mechanism for climate and the seasons ?. That's right,you would rather show each other pretty pictures and pretend that astronomy is all about magnification. |

Because the Earth's spin is not exactly aligned with the Earth's orbit around the sun, the Sun sometimes shines directly over the northern hemisphere, and other times shines directly over the southern hemisphere. For instance, the sun reaches its most northerly position (the tropic of cancer) on June 21. This is called the "summer solstice." If you were standing on the tropic of cancer on June 21, the sun would be directly overhead at noon. This is the first day of summer in the northern hemisphere, and the first day of winter in the southern hemisphere. Because the sun is shining more directly in the north than in the south, the weather is warmer in the north in June. In December, the opposite happens. The sun is over the tropic of Capricorn, and is shining directly at the southern hemisphere. So December is summer in Australia and Brazil, but winter in America, Europe, and Asia. Some people believe that summer is when the Earth is closest to the sun. This is not true. In fact, the Earth is farthest from the sun in early July, The challenge is actually a waste of time when you know the answer and the cause for cyclical hemispherical weather patterns is certainly not variable inclination of the Earth as the following graphic would have it - http://www.astronomy.org/programs/se...flashlight.gif All this fuss over climate imbalances and global warming and I have yet to see a correct explanation for what causes cyclical weather patterns in the hemispheres and all encompassed by global climate and the motions of the Earth.The price of your observational convenience based on celestial sphere geometry and your magnification hobby is the inability to work with the axial and orbital motions of the Earth as they apply to climatology and so much else. Seasons occur because of the majestic motions of the Earth,specifically the change in the Orbital shadow/Solar radiation boundary against rotational orientation.Of course,this majesty is availible to astronomers while variable axial tilt is for those who know no better,at least with 21st century imaging and data. |

The motions of Earth and its orbital position from the Sun dictate
the background for global climate and what makes existence possible,in fact most people are astronomers by living by the daily and annual cycle of the Earth.For you magnification folk,you probably notice that people are interested in astronomy through climatology and are paying closer attention to the planet after being bombarded for decades with huge sweeping statement about the universe. Google news is full of astronomical content even though astronomers are absent from the discussion. http://news.google.com/nwshp?ie=UTF-...ncl=1114966083 Your reaction is expected just as Sam's standard stock reply is and the theorists poor attempt to argue for a variable tilting Earth.What is not expected,but hoped for,is a courageous person who has enough sense to see where astronomy and climatology mesh and make the neccessary modifications to suit 21st century concerns.

This is the way the seasons work.- Hide quoted text - - Show quoted text - Here are the temperature bands which set the conditions for global climate - http://www.climateprediction.net/ima...ges/annual.gif The oscillation of those temperature bands over the course of an annual orbit of the Earth depend on how long a location spends in solar radiation or in the orbital shadow as the main component. Hemispherical weather patterns or the seasons as you know them are a distinct hemispherical subset of global climate insofar as weather conditions of temperature,precipitation and the nature of the precipitation (rain,snow) atre due to the conditions set by the orbital cycle of the Earth . You do not try to explain hemispherical weather patterns directly through the motions of the Earth (hence your variable axial tilting Earth),what you do is explain global climate using the orbital motion and path of the Earth and determine that the SR/OS boundary alters against rotational orientation. Right now you have a bunch of guys fixated on CO2 levels and making a good job of scaring people with future predictions,these same people do not even explain the known cyclical hemispherical weather patterns( seasons) for the Earth correctly or rather use a pseudo- dynamic of variable axial tilt to do the job that the Earth's orbital motion does. |

There is no sense here that anything is wrong with a variable axially tilting Earth,not the slightest sign of recognition that there is a productive way to split global climate from hemispherical weather patterns (seasons) and explain the former astronomically and allow the latter to exist as a meteorological prediction convenience. I am well familiar with the politics of all this and have nothing to say about what will occur as the 'theoretical' excesses of the last century are set aside for the new agenda of climate 'predictions' and all its dire warnings.My policy is making people aware of the terrestrial consequences of the motions of the Earth and how the cycles makes existence possible,cycles that you lot spent centuries ignoring for the convenience of celestial sphere geometry and observational predictions based on the calendar system.Considering that in all the years promoting the system where clocks keep in sync with axial rotation in 24 hours/360 degrees reflecting the daily rotational cycle of the Earth via the human devised Equation of Time principles that I have yet to see one person affirm it,makes the appreciation of the more intricate astronomical/climatological material less likely now than ever. |
