A couple of things I’ve discovered over the years and some observations:
1) Conspiracy theorists never investigate real conspiracies because the fake ones are much safer to investigate. Investigating real conspiracies can get you hurt or killed. This is why Monckton can safely rant about Global Warming being a conspiracy by what essentially comes down to the Illuminati, but we see very little in the mainstream media about how the deniers function.
2) The professional deniers know what the consequences of their actions will be if they are successful, in fact they are counting on them. If large areas of the Earth are turned into lifeless desert that opens up all kinds of opportunities for oil and coal exploration. Besides we will need those energy resources to survive in a world growing more hostile to life. So what if a large portion of the Earth’s population dies, it will mostly hit the poorer people who don’t buy much coal and oil anyway. This is the way they are thinking.
3) Drawing parallels between “Climategate” and Watergate may not be a bad thing. I recall that there were a series of other break-ins before the Plumbers were caught that caused all kinds of problems for the Democratic party and helped Nixon get elected. But the investigation of Watergate break-in eventually revealed the truth. I expect that a similar series of events can be made to happen by investigating who was behind the hacked emails.
