Would you go to and live on an Earth that does not tilt between the seasons? Basically, the noon Sun angle over the equator is 90 degrees every day of the year and the weather conditions are equivalent of March 21/September 21 year-round.
That would probably kill most complex life from the planet within a few generations, so no.
Think about the implications. There would be TONS of mosquitoes, with no freeze to kill them off they would just continue to multiply year-round. Alligators and snakes would move north. Zika and other diseases would also move north. The seasons are just fine the way they are.
I would, and I'd pick my spot to be mid-October (here) every day.
Yes! I would love it!
We have evolved to be most efficient in seasonal climates.
No cold? No below 0 weather, icy roads, or the need to bundle up just to walk outdoors? You bet!!!
