Ever since discovering the Universe Sandbox, I felt as though I've found the opportunities to see all the astronomical scenarios in my mind come into fruition. But, of course, one question at a time.
Earth's current axial tilt is 23.5 degrees, ideal for the possibility of the four seasons. Whenever I rounded it up to 25 degrees, people say that I end up getting hotter summers and colder winters--in short, more seasonal extremes.
So my question is--regarding the 25-degree axial tilt and the seasonal extremes, how much is "more"?
