For example, I have fairly decent pattern recognition skills. And I've been hiking the same trails on the north side of the Hollywood Hills for the last 45 years. Having grown up in a dry region, I am a big fan of verdant nature, so I pay careful attention to how green the hillsides are at each point in the season.
Now, you might think that I would have noticed evidence in these wooded canyons and sagebrush hillsides of long-term Climate Change. But I haven't.
I am not saying it's not happening. Perhaps there is a long-term trend that remains invisible to me under the much more visible seasonal cycles and the random noise.
What I am saying is that, at least so far, a highly observant and statistically-minded citizen such as myself hasn't noticed Global Warming going on in his own environment. Without the aid of Global Warming Awareness Campaigns, I would never have become aware of Global Warming just by hiking in the same environment decade after decade.
I think that explains a lot of the Gnostic appeal of Global Warming Awareness. When you become Global Warming Aware, you are superior to the unenlightened masses. You have access to evidence of things unseen. You are one of the elite who are aware of knowledge that can only be gathered through the most esoteric means and analyzed by the most profound scholars.
In contrast, much of the things that I notice in my daily life, such a racial differences in crime rates and intelligence, are the kinds of things that are so overwhelmingly obvious that many people take pride in not knowing about them. (At least, they don't know about them when discussing public issues. They seem to know about them just fine when choosing where to buy a house or when deciding where to school their children.)
In fact, many popular people actively engage in Anti-Awareness Campaigns intended to increase ignorance. (For example, the President of the United States likes to boast of his long fight against awareness of racial crime rate gaps.) For this, they are showered with public approbation.
