Brandon Rogers’ letter in the January issue of PAW is right on. It is not the production of fossil fuels that raises atmospheric CO2, is it their consumption.

In addition, my own studies, based on historic data from multiple sources, have shown that both atmospheric CO2 and global average surface temperature (GAST) are directly proportional to world human population. If we do not curb our population growth, Mother Nature will do it for us.
