Diary: Lawdy, Lawdy my how things change
Look, everyone who reads this knows that I am a JMG fanboy. To a lesser degree, Ugo Bardi is right up there too.
But these two are complete doomers. It seems that they have partnered up to explain how the laws of thermodynamics means that we are doomed, doomed I tell you. Well.....no shit sherlock. Now, I am not disagreeing with their predictions or their analysis of the past, but I think that things there are a little broad brush in my opinion.
I am not completely certain that anyone "knows without a doubt" how things were in the distant past. All the data is derived from indirect means. Long term temperature (>2000 years ago) are derived from ice cores and tree rings. These aren't "bad", but they do have margins of error that make their truth less than "absolute". I also have a sneaking hunch that the farther back you go the dicier the data. But in truth, it is the best we have and we need to use it.
Ugo is currently on a rant on how CO2 is the most terrible-ist thing ever. Well buckaroo, while it ain't great, it is just another thing that our grandchildren will have to curse us for. JMG longs for a past that never really was.
Mostly I just figure that we are just another species. We have memories of the past and predictions of the future. We have hunted species to extinction and rail against other opportunistic species. But we have also watched species die out when we had nothing to do with it.
Look, the world is constantly changing. I suppose I am a "evolutionist" in the sense that the world will be different in the future, but that happens. I see no reason to get all atwitter because things are changing and there isn't a damn thing I can do about it.
But today is a nice day. I am going to forget the problems and visit an old lady.
