Greta Thunberg is both a cause and an effect in the great shift that's ongoing in the public opinion about climate change. Climate science deniers are feeling the pressure and they are preparing to change their strategy. No more denying that AGW exists and that it is a danger for all of us. It is time to move to foot-dragging for profit.
A post by Tim Ball on the despicable WUWT blog is well worth reading because it summarizes the plight of climate science deniers in the current debate. Ball says that he calls it quits because:
"you are asking people to believe that a small group of people managed to deceive the world into believing that a trace gas (0.04% of the total atmosphere) was changing the entire climate because of humans. In addition, that group convinced many others to participate in the deception. The public view is that deceiving so many is just not possible. "
Stark clear: Ball perfectly summarizes the problem for him and his band of science-deniers: how could anyone believe what they are saying? With Greta Thunberg bursting into the debate, their position is rapidly becoming untenable. So, they are shifting away from discussing whether AGW exists or not. Ball says,
"I decided to stop trying to educate people about the global deception that is AGW. ... The challenge now is to help people understand the differences between deceptively derived policies, and what is the best, most adaptive, most profitable, and most rewarding strategy for survival of the individual, business, or industry. "
And I couldn't have said it more clearly. Ball and his ilk are preparing for a war of attrition against the attempt to do something to save humankind before it is too late, all in the name of the "most profitable" strategy.
