If climate change were to suddenly reverse itself (because of some yet undiscovered mechanism of balance in our climate system), my guess is that the denialists would be triumphant, the skeptics would be skeptical this time of the apparent good news, the warners would be relieved, and the calamatists would seek out some other doom to proclaim.
If climate change keeps getting worse then I would expect denialists to grasp at stranger straws, many skeptics to become warners, the warners to start pushing geoengineering schemes like sulfur dust in the stratosphere, and the calamatists to push liberal political agendas — just as the denialists said they would.
