title: Wrestling with 'doubt-sayers': a first step in leading community-wide climate change action for better health.
abstract: OBJECTIVE
  Although the evidence base for climate change is indisputable and the potential human health impact is extremely concerning, to date public health professionals are playing little part in influencing community change to accept and act on the science.
  
  
  METHODS
  In reviewing the techniques used to obstruct action on tobacco control by vested interests through constantly raising doubt about the science in this arena, a similar pattern is seen in obstructing action on climate change.
  
  
  RESULTS
  It is clear that the raising of unverified doubt is the primary tool employed by profit-driven corporations to prevent constructive action in both these arenas, with the very high potential for the health of the whole population to suffer as a result.
  
  
  CONCLUSIONS
  Those promoting the health of Australians have a responsibility to optimise health in this regard and need to think differently through embracing complexity science and then take action, with the first step being to provide constant counter-arguments to the unsubstantiated statements of the 'doubt-sayers'.
