350? or 330?
Havning just finished the 350 Rally at HK, i couldn’t help but to think about the number 350ppm - which 350.org and many other people like Al Gore etc. recognised as the safe upper limit.
But i couldn’t help but to noitce:
For the past 800,000 years, the planet has been self balancing at 280 ppm.
Here is some new development:
Top climate scientists say that the atmospheric CO2 needs to be urgently reduced to 300 ppm to make the planet safe for all peoples and all species (see 300.org: http://sites.google.com/site/300orgsite/300-org ). However, with global annual greenhouse gas pollution still INCREASING it is clear that World governments still do not appreciate the dire urgency of the problem. The worst offender by far is Australia which has annual per capita Domestic and Exported GHG pollution 10 times that of China, 25 times that of India and 60 times that of Bangladesh – but which under its policy of “5% off 2000 GHG pollution by 2020” is committed to INCREASING its Domestic and Exported GHG pollution from 2000 levels by 40% (2020) and by 80% (2050) (see: http://sites.google.com/site/yarravalleyclimateactiongroup/australia-s-5-off-2000-ghg-pollution-by-2020-endangers-australia-humanity-and-biosphere ).
