[by Dean Smith] Since May 1974, the National Oceanic Atmospheric Administration (NOAA) has been tracking CO2 concentrations in the earth’s atmosphere. In a recent release, NOAA announced that the month of March of this year had the highest level of CO2 in the atmosphere of any month since the organization started tracking CO2 concentrations. It uses 40 sites to record CO2 levels. Computers then calculate the global average using these measurements. For all 31 days of March, NOAA recorded CO2 levels of 400 parts per million. However, this finding is not good news for those pushing the man-made global warming agenda because of greenhouse gas. The reason: for the 18th year, fifth month in a row, global warming temperatures have not risen as measured by the Remote Sensing Systems (RSS) on satellites.
