Axial Tilt and How It Affects the Earth

If the earth was at an axial tilt of 0° there would be absolutely no seasonal change, the temperature would remain even at all times of the year. The temperature around the equator (0°latitude) would be about 40°C or 104°F, and the 80°N latitude would be at about -35°C or -31°F; with the temperatures remaining this way all year round and no seasonality migration and aggregation of the poles would be mythical; also would be too cold for reproduction hence no “annual flush of productivity.” In the desert there would be now wet season which is an absolute requirement for terrestrial life in this biome. The earth’s sustainability would be minimal if the axial tilt were nil. Ratification of all earth’s species (besides extremists) would be embedded between approximately 20°N-60°N latitude; temperatures in these areas as follows 20°N latitude 35°C (95°F), 40°N latitude 20°C (68°F) and 60°N latitude -5°C (23°F). With the earth’s axial tilt at 60° the seasonal temperatures would be more extreme than those we are conscientious of presently. In the equator’s vicinity the temperature changes from season to season would fluctuate from -5.4°C (22.3°F) to its accustomed temperature of 40°C (104°F). In a latitude of 80° the range of temperature would be reaching below -60°C (-76°F) to 35°C (95°F). Temperature range for the other latitudes as follows: 20°N range -34°C- +40°C; 40°N-60°N ranging from below -60°C- +40°C. With extreme temperatures like these the earth would remain livable but only in a much more diminutive area although with migration attained in the warmer seasons more sustainable areas become available yet many of the species seen on earth today would be abolished. A 90° axial tilt of the earth would induce utmost extreme seasons basically uninhabitable conditions. The equator would incur temperatures ranging from -50°C - +40°C which may possibly be the only portion of earth that would be sustainable for only limited species. The rest of the temperature ranges...
