| Summary: | This comment is meant to address the unproven attribution of climate change to man-made influences, specifically from key finding #1: “1. Human-induced climate change and its impacts are apparent now throughout the United States. • Global warming is unequivocal and is due primarily to human-induced emissions of heat-trapping gases and other pollutants” This statement can not be supported when looking at the facts and must be removed. We will show how by process of elimination the greenhouse component must be a very minor one. CO2 has generally been portrayed as increasing over the past century based on direct measurements spliced with ice core estimates. I will not get into the claims by atmospheric physicists, chemists and geologists (Jaworowski, Segalstad, Beck) that ice core data is fraught with errors and uncertainty and may be very different prior to 1958 but assume that depiction is correct for the purpose of this analysis. In addition the CCSP ignores all the other man made localized effects as I discussed in a prior comment and other commenters have addressed like insufficient adjustment for urbanization, land use changes and siting issues which are more important than greenhouse gases. The CCSP dismisses any natural factors that are present. This document will compare the CO2 temperature correlations with the correlations with natural factors and show that natural factors can not be ignored and use of historical cycles to predict the future states and adaption are the only sensible solutions. |
