How sweet but then again you have to discover a planetary climate spectrum between a Polar climate (0 degree inclination to the orbital plane) and an Equatorial climate (90 degree inclination to the orbital plane much like Jupiter - http://calgary.rasc.ca/images/planet_inclinations.gif It means the Arctic circle would extend down to roughly the latitude of Portland Maine whereas presently it is way North - https://jsis.washington.edu/archive/...datreeline.jpg All the traits that belong within the Arctic circle would extend downwards to lower latitudes with increasing asymmetries of daylight/darkness and temperature fluctuations as greater surface areas defined by latitudes experience great swings between warm and cold across half an orbit. A polar climate doesn't necessarily means a colder climate as opposed to an equatorial climate, it represents the rate of change in surface conditions across half or a full orbit of any planet. Of course the orbital proposal which predates De Revolutionibus allows for this climate spectrum for what is called axial precession is really the normal annual increase and decrease in surface areas, expressed as a circumference, where the Sun is in view or out of sight as a function of an orbital surface rotation - https://en.wikipedia.org/wiki/Axial_...recession..svg The arrow is facing the wrong direction and the entire surface turns parallel to the orbital plane as a function of the forward motion of the Earth through space but unfortunately the system Copernicus used when correctly identifying this motion was based on Ptolemy's framework where the Sun moves through the constellations and not on the older but more accurate perspective where the background stars come in season. Axial precession is really a distinct surface rotation so that happens across an orbit hence the easy means to explain the Polar day/night cycle with Polar noon at the South Pole in a few days - https://epic.gsfc.nasa.gov/ |

Don't see why would our planet vaporise? Says more about you and your (lack of) understanding of fairly basic physics. Let's say a large asteroid would hit our Moon, knocking it out of orbit or much farther away, so earth would wobble more? An asteroid big enough (or fast enough) to have enough energy the moon out of its orbit wouldn't knock the moon out of its orbit, it would shatter it, and turn a great deal of it into plasma. And that wouldn't be nearly enough energy to alter the Earth's tilt that much. -- Terry Austin Vacation photos from Iceland: https://plus.google.com/u/0/collection/QaXQkB "Terry Austin: like the polio vaccine, only with more asshole." -- David Bilek Jesus forgives sinners, not criminals. |

(It is likely that our Moon is what has kept the tilt of the Earth's axis so stable. Mars, for instance, has seen much wider swings.) Well, 500 years ago, earth's population was around 500 million, now 7 billion! 200 years ago , industrialization caused the exponential population growth! Going back to 1/2 billion would be a normal thing, I think!

And the whole collapse of civilization thing would be nice to avoid! (This is likely to happen in any case, but by our own making, not some mysterious adjustment of Earth's axis.) |
