There’s a third way, which suffers from the problem that it is subtle, neither black nor white, and doesn’t do well in sound bites. It’s a “lukewarm” synthesis, arguing indeed that humans have something to do with the rise in surface temperature measured since the mid-1970s, but that it is hardly the end of the world as we know it. This view claims to accommodate the seemingly odd behavior of temperature in the last 15 years.

Each of these positions – let’s call them hothead, flatline, and lukewarm – are testable against observed history and theory.
