Well, I'm assuming you have a reason you consider Rockefeller (though, there are several to specify from) a monster. It is why I asked.
To the first paragraph. They stated an enemy to the common man real or imaginary unites them. This is generally sown through an unknowable force when imaginary, researchable and critical when real. Such as the Soviet Scare to Americans. The threat was both real AND imaginary, because it hinged on how they believed the Soviets were going to one day launch war on America, which was both a possibility and fantasy as there's no real way to say the Soviets WERE going to do it, even if they planned it. Imaginary scares will only work when patrolled by a small, controlled group in constant contact who control all of the data, while nobody else is able to do any investigation on this to reveal the potential fallacies of it. This situation happens to not be the case, as it is fully allowed for other people and stations outside of the group to research, determine, and interpret all data.
To move on to your second paragraph, there are two pieces to address:
It is still never directly stated that there is an imaginary enemy to combat, nor is there one so grand for people to fully rally behind. However, the truth of the matter is, the wording is tricky and fairly irresponsible to put forward. I would imagine they expect recoil and investigation on anything they put out, and probably is their aim to begin with. The problem truly is, I cannot recall any reports or statements where scientists have investigated and found proof against Global Warming aside from side data analyzed by climatologists, which doesn't seem to be built enough to stand the argument. Generally the argument against "warmers" is the sometimes lack of data climatologists have.
To move on to the second half:
To completely invent an event with the Earth, and then half thousands of scientists behind it after moderate research would be nothing short of a miracle for a single group of around fifty people, even one hundred people. To "fudge" it a "little" is most likely true. If the event is still there, to produce the shock needed to bring attention to their cause would probably have them playing up the dangers of Global Warming. The true problem generally is people, scientists, politicians, and the lives none of them overlap. For people, it's extremely reactionary. They see events going on, people panicking around them, or events contrary to what they believe to be the truth. In this event, people are far more likely to simply disbelieve in those who hold some form of authority over them, as it's commonly believed that the people over them simply would like to continue supressing them in some fashion or another. For scientists, they are generally in a more relaxed state. Rarely do we believe something happening will overtake humanity right away, and will generally undergo research and testing on the subject matter in a generally objective way as to best understand the situation, the effects we can have on the situation, and solutions we may have for the situation. A big problem is how scientists and data collection works, how people understand it, and how politicians endorse it. In the end, politicians are what drives most detractors. People generally view politicians as having personal schemes and lies, given a broad experience of people hearing about such things (which may or not be embellished by people reporting them, and the people talking about them). This is where the real problem begins, as Politicians generally are people who use force and shock to get people to garner to their sides. This includes scare tactics, and embellished truths. When a politician begins to endorse any form of science, the people who rarely understand the processes behind it begin to doubt it's legitimacy, with reasonable cause from the distrust of the politician. This is where it hurts understanding between scientists and people: Scientists are generally slow workers in more secretive areas so their work isn't to be taken out of context, or misinterpreted, and work literally by the time table funding allows, while Politicians stress urgency. People pick up on the urgency, and see the secretive information being taken slowly by scientists as a problem. Which is highly understandable. People are emotional, they're prone to fear, hate, anger, disgust, conspiracy, violence, anxiety and so on. So when they are confronted with two fronts, such as science and politics, who work together in many ways (weaponry, reasearch, medicine, the like), they believe they are on the outside, with the middle forcing them there.
However, I do not view regular people as dumb. I just view them as regular people. They're not scientists who've had to walk the line of datastreams while pushing the heart away, they're not politicians who make it their lives to talk to large groups of people about problems aspiring to people's hearts. They're just regular people who have things beyond their control happening to them, and generally believe those in control do not suffer similar fates. People are just really people, and will continue to behave as people. It's why the statement was made about people not working together until there is a common enemy, because unless there is one, people just turn on each other as common enemies since they have nothing else to polarize against. People aren't dumb, they're not really sheep to be led around. They don't like it, they never have, they never will, and will always rebel when they start being told how they're destroying something, or how they should live.
