I live in the Arizona White Mountains where it is usually in the 60s (Fahrenheit) by mid October and it’s still in the mid 80s/high 70s. I know seasons are caused by the tilt of Earth on its axis and as it travels around the sun it gets more/less intense sun. But if we are still tilted and at the same place around the sun as we are every year, what causes an unusually warm Autumn season?

The answer in this case is that decades of greenhouse gas production have led to more heat being retained by the atmosphere, causing the weather to be more intense and generally more hot.
In short, global warming is real.
