350 or 300? Climate activists advocate 300 ppm CO2 for a safe planet for all people and species
The US-based organization 350 has planned for 24 October 2009 as an International Day of Climate Action – as a global day of action demanding a REDUCTION in atmospheric CO2 concentration from the present damaging 387 ppm to at most 350 ppm (in contrast the corrupt and inept world governments are all aiming to INCREASE atmospheric CO2).
Informed by the latest science, Australia-based, but hopefully International, 300 was formed to educate the public about the urgent need to reduce atmospheric CO2 from the present damaging level of about 390 ppm to a safe and sustainable level of 300 ppm.
300.org enthusiastically endorses the 350.org 24 October 2009 International Day of Climate Action but recommends the number from the latest climate science of “300” (see “Re 300.org & 350”.org) .
Here are comments from some major climate activists and climate action groups who have summed up the latest scientific evidence and conclude that there is an urgent need to reduce atmospheric CO2 concentration to 300 ppm.
