The maximum global temperatures variations occur between the
Solstices representing the specific orbital points of the orbital motion of the Earth yet not one single organisation,including NOAA,explains the seasons properly - http://www.crh.noaa.gov/fsd/astro/season.php Does anyone here doubt just how important it is to rein in this reckless social tyranny which converts what would normally be a productive effort to reduce pollution into this incredibly unfair substitution by labelling it global 'climate change' - http://www.noaanews.noaa.gov/stories...atereport.html This 'modelling' is a dangerous business to the exclusion of all other inputs and especially the central one of planetary dynamics,should any further variations in temperatures occur up or down,any changes due to other inputs are locked out to serve carbon dioxide solely.Surely there are a few sane people still around to determine that this empirical railroading of temperature spikes towards human influences displays the worst possible traits of speculative excesses. I can't even get one here to affirm the temperature variations of the day/night cycle through daily rotation never mind the orbital specific for seasonal variations therefore this is not a game and never has been.The idea is to teach astronomy and not counter pollution concerns which will always exist yet omit astronomy and there is no way to distinguish weather from climate. |

If our whole conception of why we have seasons was wrong, yes, I can see this might mean we couldn't properly explain things such as how long-term orbital variations contribute to ice ages. The surface of the Earth is cooler than the surface of the Sun. So the Sun emits energy in the form of visible light predominantly, while the Earth, not even red hot, radiates heat away into space at night in the form of long-wave infrared. Carbon dioxide blocks those rays, being warmed by them. However the Earth's orbit works, that orbit hasn't changed much recently. So it is unclear what you might have to contribute to the global warming debate, even over and above the fact that how the seasons are conventionally explained seems clear and well-founded to us. Perhaps there is some problem with how we word our explanations of it, which seem to imply a variable orientation for the Earth, which cannot be the case, as Polaris is the pole star all year long. That what varies instead is the relationship between the Earth and the Sun due to the Earth's orbit around the Sun... is something we already know quite well. But a fixed orientation relative to the stars does translate into a variable tilt relative to the Sun if you ignore the stars and concentrate on the line going from the Earth to the Sun. Which may be why Copernicus spoke of a "variable tilt", and it goes along with your preference for viewing the period of the Earth's rotation as 24 hours rather than the shorter "sidereal day".

Can't we just crucify the feckwit on a large equatorial mounting and
be done with it? |
