Climate science - vicious attacks and deniers

 I have just finished reading an interesting article by Clive Hamilton on "Bullying , lies and the rise of right wing climate denial" I find it quite interesting when journalists start writing a series of moderately in depth stories such as this. I too have noticed a considerable increase in the stridency and aggressiveness of tactics from climate change deniers. Having attended lectures with David Karoly and other climate change activists I'm not surprised they are receiving vicious emails etc. I too feel that the debate has degenerated into attacking the person and climate change scientists are also able on this regard. However, so far as I have heard, their attacks have been in the nature of semi-humourous pokes at the deniers and often include rebuttal to the science of the anti-climate change deniers.
I will be reading Clive Hamilton's next piece on who is behind the attacks with interest. As a librarian I know that even public places such as library computers are monitored by a variety of mechanisms. So although these vicious, swearing and orchestrated attacks will be difficult to trace, I hope the culprits are caught and prosecuted. Such type of debate is not needed in our society.
Overwhelming internet facilities with avalanches of attacks is not new in Cyberspace as Google recently found out in China. Even innocuous sites such as libraries can succumb to such disgusting tactics. 
I wonder whether politicians will have to develop stronger measures to fight mass email and other lobbying tactics (vicious or not) to find the true feelings and values of a population.
