'The seasons are not caused by the tilt of the Earth,the seasons are caused by daily rotation and the orbital motion of the Earth,each with its specifics characteristics.It takes people with common sense to work out the details and when they do they will have little appetite for childish affairs and nuisances who believe humans can control global temperatures. Amazing thing when it is now possible to see two separate rotations to the central Sun that all planets have and nobody can apply the observation to the Earth - http://hubblesite.org/newscenter/arc...99/11/video/b/ No wonder the English are about to lose GMT as the timekeeping standard for no good reason even though it is almost impossible to do so. |

The seasons are caused by the tilt of the earth, but the tilt itself doesn't change. If there was no tilt, there would be no seasons, well except perhaps for a slight variation due to the Earth having an elliptical rather than a spherical orbit. -- Col Bolton, Lancashire 160m asl |

The seasons are caused by the tilt of the earth, but the tilt itself doesn't change. If there was no tilt, there would be no seasons, Poor reasoning,if the Earth's rotational orientation aligned with the travelling orbital axis,the planet would experience conditions similar to that experienced at the equator,if 90 degrees almost like Uranus then the planet would experience polar conditions.If you have trouble with the 'orbital travelling axis' I suggest you look at the sequence of images of Uranus again there the rotational axis for daily rotation is almost 90 degrees from its orbital traveling axis around which the planet;s polar coordinates turn to the central Sun - http://www.daviddarling.info/images/...gs_changes.jpg Due to its inclination,the Earth has a predominantly equatorial climate as to Uranus which is almost totally polar hence there is no such things as 'no seasons',there are either equatorial or polar conditions. It sometimes happens that no matter how hard readers try,they cannot see the East/West turning of Uranus to the central Sun which constitutes its polar daylight/darkness cycle and then apply the rules to the Earth. well except perhaps for a slight variation due to the Earth having an elliptical rather than a spherical orbit. -- Col Bolton, Lancashire 160m asl |

If there was no axial tilt wrt the plane of orbit then there would be no seasons. How could there be? The path of the sun in the sky would remain constant, as would day length as would temperature, so no seasons. Obviously polar regoins would be colder than equatorial ones due to the lower altitude of the sun, but that would be it. It would be like eternal March 21st or September 21st. -- Col Bolton, Lancashire 160m asl |

It is not your fault,you are only asked to look at the East/West turning of Uranus to the central Sun,note that it will turn in a 360 degree cycle/circle to the Sun once in 84 years and drop the idea that Uranus tilts with respect to the orbital plane,Sun or whatever other reference you choose. http://www.daviddarling.info/images/...gs_changes.jpg In the sequence of images,you not be able to see the South/North daily rotation which defines the polar coordinate ( rotational axis) and the East/West turning defined by the turning of the planet around a 'traveling orbital axis' that runs almost North/South from Equator to Equator and yet you do see the planet turn to the central Sun. The path of the sun in the sky would remain constant, as would day length as would temperature, so no seasons. It is not quite like that,the Earth has variations in natural noon which would occur in the same manner regardless of inclination.The Earth turns 360 degrees to the central Sun every day and this is why temperatures rise and fall,the Earth also turns to the central Sun as a component of its orbital motion and this turning is uneven hence the combined daily and orbital motions generate variations for each noon cycle and these variations are global regardless of latitude as long as the Sun is seen every day. There is no such thing as 'no seasons' and this is extremely important,a planet can have an equatorial climate, a polar climate or somewhere in-between as it depends of the relationship between daily and orbital characteristics.The Earth has a largely equatorial climate and it just requires readers to dwell on those images of the polar climate of Uranus long enough to get accustomed to the comparisons with Earth and work in the details. Obviously polar regoins would be colder than equatorial ones due to the lower altitude of the sun, but that would be it. It would be like eternal March 21st or September 21st. -- There are both orbital and global conditions that you are omitting by lunging at such a conclusion yet such is this era where a blind eye is turned to the cause of the polar daylight/darkness cycle,if you could turn your attention to this known experience you would think differently about weather and climate.

It is perfectly easy to demonstate the seasons on Earth by moving a globe about a central object. It will be seen that at one point the northern hemisphere presents itself (notice I didn't say 'tilts') to the sun in such a manner as to allow sunlight to strike at a higher angle thus causing summer. 180° along the orbit, the same thing happens for the southern hemisphere. There are both orbital and global conditions that you are omitting by lunging at such a conclusion yet such is this era where a blind eye is turned to the cause of the polar daylight/darkness cycle,if you could turn your attention to this known experience you would think differently about weather and climate. Looks like the rest of the scientific community have 'lunged' at this conclusion too. But you're right and everybody else is wrong..... -- Col Bolton, Lancashire 160m asl |

E-mail: change boy to man Teach evolution, not creationism:http://evolutionnotcreationism.org.uk/ What is so difficult about acknowledging that all locations on the planet experienced a single orbital daylight/darkness cycle due to the orbital behavior of the Earth where the polar coordinates,where rotation is at its least,act like a beacon for the orbital trait ?. The spectacular sequence of images of Uranus where the equatorial rings act like an orbital longitude meridian as the planet turns in an 84 year cycle would normally be good enough to affirm the replacement of 'tilt' insofar as planetary climate descriptions can be considered as either largely equatorial or polar rather than the idea of seasons/ no seasons. http://www.sflorg.com/spacenews/imag...2307_01_02.jpg Let the world be pestered with people who believe they can control the world's temperature through a minor atmospheric gas,investigators have to clearly distinguish seasonal weather patterns from global climate, make it interesting and enjoyable. |
