Global warming promotes the idea that temperatures have increased around the world due to too much manmade carbon dioxide. Of course, there are alternative explanations. Reasonable people point out that most heat is trapped by atmospheric humidity, water vapor – about 95 percent, in fact; thus, CO2 is a fairly minor component of the heat-trapping environment.
But facts do not get in the way of what seems to be "a good story." Proponents of global warming or climate change wish to use the concept to introduce a fairly Draconian regulatory regime that will control people's usage of energy via Smart Meters and other devices. The global warming promotion is thus a Trojan Horse leading to additional oversight of how people use energy and lead their lives.
Proponents of global warming (or climate change) deny they have such intentions. They also claim that atmospheric humidity is not the problem. What goes on in the atmosphere is "normal," they argue. It is the insignificant additional "manmade" carbon that is doing all the damage. Everything would be fine, but it is what human beings are producing now as a result of the industrial revolution, etc., that has caused the disaster-in-the-making.
Since this meme has been partially discredited by the email scandal called Climategate, followed by Climategate II in 2011, global warming terminology has changed. These days the "PC" term is "climate change." Like Peak Oil, another fear-based power elite meme, global warming was more popular in the mid-2000s before the financial crisis began to concentrate people's minds and Climategate emails showed that proponents of global warming had conspired to hide contrary evidence and had apparently lied about data, conspired against dissenting views and generally done everything in their power to turn an opinion (the world is warming) into an actionable perception.
After the Climategate emails came to light, there were several quasi-formal panels that examined the matter with risible results. Witnesses were not called and the assertions of those responsible for the emails and data misrepresentations were apparently taken at face value. The show must go on.
Despite the conflation of the Internet, war-problems and the economic crisis, the elite still pushes ahead. Yet the more promotions like global warming stagger forward, zombie-like, the more resentment they will generate. The process will continually damage the legitimacy of modern regulatory democracy, which is the most powerful promotion of all. Generally, this is a dangerous situation for the powers-that-be.
