Is 350 ppm Safe? Hell, NO!

Folks, don’t be fooled by the hype: 350 ppmv NOT safe!

1. There is a 30-year time lag between the release of CO2e greenhouse gases to the atmosphere and the cumulative impact of heat-trapping mechanism taking effect.
2. The positive feedback system whose impacts we are now witnessing started when the atmospheric CO2 concentration rose above the 330 ppmv in the mid 1970s.
3. Any concentration level above the 330 ppm is clearly unsafe. To stabilize at levels below 330 ppm, we must aim for much lower levels of about 260-270 ppm.
