Any scientist that even attempts to come to conclusions on global warming with 100 or even 1000 years of data is a fool. To insist that the temperature trends of BEST mean anything or that any trends that we see have meaning is assuming so much when what we really lack is real information….the warming over the last 100 years for instance is nothing but a second in a day of the climate, and to claim that you know everything there is to know about the climate based on 100 or even 1000 years is to be the expert fool. I think the problem here is an educational issue where scientists so fell in love with ideals and computers that they forgot the first step in the scientific process where we actually have to prove what they state. In this case, we are left with science in shambles, and a bunch of expert fools running around telling us how we must live our lives.
As this chart shows here, the more long-term trends show us the current trends as being less scary. If you notice the long-term graph above, the rise in temperatures that has occurred recently is not very scary at all and look rather normal when you look at the big picture. Should we allow people who show us clipped versions or “selected versions of reality” really tell us how to live our lives? I think this picture here tells us all we need to know in that regard. Nothing scary is occurring and even if CO2 has an impact, it is more than likely minor and the warming we have seen in the last 100 years is natural and nothing to be concerned about.
