"By sounding their bells or other instruments 350 times, participating churches will symbolise the 350 parts per million that mark the safe upper limit for CO2 (carbon dioxide) in the atmosphere according to many scientists," it added.This is nonsense. According to the authors of the book SuperFreakonomics, CO2 concentrations were 1,000 parts per million (ppm) some 80 million years ago, back when many mammals were appearing. Since CO2 is good for plants, most commercial hyrophonic greenhouses have supplemental CO2 at about 1,400 ppm. By contrast, our current atmospheric concentration of CO2 is only 380 ppm.
Further, CO2's effect on the temperature is minimal to begin with and cutting concentrations by 30 ppm (down from our current levels of 380 ppm) would have no discernible effect.
However, it is totally appropriate that liberal churches ring their bells for global warming -- since the latter is more of a religious faith than a fact.
