300.org: “300.org exists to inform people about the worsening Climate Emergency, the worsening Climate Genocide and the urgent need to reduce atmospheric carbon dioxide (CO2 ) concentration to a safe and sustainable level of about 300 ppm. It has a lengthy numerically- and alphabetically-organized compendium of numerous expert scientist and other science-informed opinions that atmospheric CO2 concentration must be reduced from the current dangerous and already extremely damaging 405 ppm CO2 (that is increasing at a record 3 ppm CO2 per year; 2016) to a safe and sustainable level of less than 350 ppm CO2 (which rounds down to 300 ppm CO2) and ideally to circa 300 ppm CO2 (scroll down to "Numerous expert opinions advocating a return of the atmosphere to about 300 ppm CO2 ASAP").
The fundamental position of 300.org is that “There must be a safe and sustainable existence for all peoples and all species on our warming-threatened Planet and this requires a rapid reduction of atmospheric carbon dioxide concentration to about 300 parts per million”.
300.org urges the World to reduce atmospheric carbon dioxide concentration (CO2) to about 300 parts per million by volume (ppmv or ppm for short). In urging a target of an atmospheric CO2 concentration of 300 ppm, 300.org is informed by the advice of top world climate scientists as set out in carefully researched and documented presentations on this site (see Sitemap).
Basically we know what the problem is (man-made GHG pollution) and how to solve it. Fundamentally, as enunciated by 300.org, we need to reduce atmospheric CO2 concentration to about 300 ppm for a safe planet for all peoples and all species. [3].
To achieve 300 ppm CO2 and a safe planet for all peoples and all species we must achieve the following:
1. Change of societal philosophy to one of scientific risk management and biological sustainability with complete cessation of species extinctions and zero tolerance for lying.
2. Urgent reduction of atmospheric CO2 to a safe level of about 300 ppm CO2 as recommended by leading climate and biological scientists.
3. Rapid switch to the best non-carbon and renewable energy (solar, wind, geothermal, wave, tide and hydro options that are currently roughly the same market price as coal burning-based power) and to energy efficiency, public transport, needs-based production, re-afforestation and return of carbon as biochar to soils coupled with correspondingly rapid cessation of fossil fuel burning, deforestation, methanogenic livestock production and population growth. These urgently required climate change actions will be assisted by divestment from fossil fuels and judicial processes to punish climate criminals” (300.org: https://sites.google.com/site/300orgsite/300-org ).
