At the G8 meeting it appears that those pretending to fight "climate change" (which used to be called anthropogenic global warming) say they are going to limit average global temperature increase since the start of industrialization to 2C. They plan to do that by limiting greenhouse gas emissions. Apparently these folks do not believe that temperature changes due to natural causes. They seem to have forgotten that 7000 years ago average global temperature was more than 2C more than it is now. They appear to have no plan for dealing with a naturally occurring increase of more than 2C, something that obviously could happen since it has happened before. They also do not seem to realize that life would be better for humans if the average temperature was 2C warmer than it is now. As far as I know they also have no plan for the eventuality of another ice age; even a drop of average temperature by 2C would harm humans far more than an increase of 2C. They talk a lot about scientists predictions of what will happen. The scientist's models have been shown to have no predictive value. So why are they basing public policy on something known to be inaccurate?
