The real deniers are the warmists... they try to deny data that shows clearly that despite rising CO2 levels that the world has not warmed in nearly twenty years. Of course this contradicts the predictions of all of their computer models.
Incredibly the data showing the lack of warming comes from government entities who know that their budgets depend on continued warming... so the fudge factor is already being maximized. Which means that we would be several years into a severe cooling trend before that was acknowledged.
Actually...no it doesn't.
It contradicts the CHOSEN outcomes of their computer models.
The computer models are loaded with chosen information, often times fabricated information. These models are repeatedly run, usually having VARYING outcomes. Seldom do the models have repeating outcomes. Basically, the outcomes are cherry picked to support a theory.
