Categories of Climate Attitude

Writing at Power Line, Steven Hayward cites a typology of attitudes toward climate change appearing in Energy for Future Presidents, a book by Richard Muller. Muller's categories:

Alarmists
Exaggerators
Warmists
Lukewarmists
Skeptics
Deniers

Hayward defines each. Based on those definitions I believe I'm a skeptic.

There has been much documented climate change in eras when humans clearly had no ability to influence what was happening. Climate science is worth pursuing, but I believe our current state-of-knowledge is not advanced enough to base sweeping policy decisions upon.
