The campaign to undermine public trust in climate science has been described as a "denial machine" organized by industrial, political and ideological interests, and supported by some conservative media and skeptical bloggers to manufacture uncertainty about global warming.
However, those politicians are now beginning to realise that unless they stop denying climate change they will not be be able to win political office. Donald Trump is one example of an outspoken critic on climate change who still voices his opinion very loudly as a dying last cry as he knows he can't win office next term.
The movement to draw attention and act on climate change has become so overwhelming that the climate change deniers are now in the kamikaze pilot mode one could say. The debate is over.
