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.
