Above is a nice reconstruction of historical temperatures, and in it I see two things: One, obvious to all, is that it is good to be alive during a warm period. Two, if you look closely, there is a downward trend with the peaks. I’ve sent away for a book on this and will address it later when I understand it better, but as explained to me in a way I did not quite comprehend, our planet enters and leaves the spirals of the galaxy at regular intervals of 350 years or so, and when that happens, we cool off. You can see by the bottom of the Little Ice Age that we might soon be entering a cool period, the prediction given as 2030. How severe – no one can say. We have a great tool, however, if it happens: Hundreds of years of fossil fuels available to us.



What follows is going to be old news for many readers, so bear with me. The issue of climate change is something that takes time to sink in for me, and I am a late arrival, so please, if you are up to speed already, humor me.
