300.org - return atmosphere CO2 to 300 ppm

300.org exists to inform people about the Climate Emergency and the need to reduce atmospheric carbon dioxide (CO2 ) concentration to a safe and sustainable level of about 300 ppm. 

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 (ppm). 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).

VERON, John E.N. "Charlie". Dr J.E.N. "Charlie" Veron: 320-350 ppm CO2 for coral reef safety
Professor John E.N. “Charlie” Veron is a world authority on coral (he has discovered and described about 1/3 of coral species), He is an  marine researcher, former chief scientist of the Australian Institute of Marine Science and author with Dr Mary Stafford-Smith (also of Coral Reef Research) of “Corals of the World. Reef building corals worldwide” (see:
http://www.nhbs.com/corals_of_the_world_tefno_98887.html ).

Professor  John E.N. "Charlie" Veron, “Is the Great Barrier Reef on Death Row?”, powerpoint lecture, joint event of the Royal Society with the  Zoological Society of London and introduced by Sir David Attenborough FRS, 6 July 2009: “450 ppm [CO2] will bring on the demise of the GBR [Great Barrier Reef] …320-350 [ppm CO2 needed]” and

“CO2 in Summary.

320 ppm: occasional [coral] bleaching

345 ppm: sporadic mass bleaching

387 ppm: inevitable long-term decline

450 ppm: rapid decline, reefs cease to be biodiverse

600 ppm: acidification affecting all biota

800 ppm: mid-Eocene extinction comnditions

1000 ppm: reefs only geological structures. Sixth Mass Extinction.” [1].

Professor John Veron (Coral Reef Research), co-signatory to the statement by the technical working group on coral, The Royal Society on 6th July 2009: "The Earth’s atmospheric CO2 level must be returned to <350ppm to reverse this escalating ecological crisis and to 320ppm to ensure permanent planetary health. Actions to achieve this must be taken urgently. The commonly mooted best case target of 450ppm and a time frame reaching to 2050 will plunge the Earth into an environmental state that has not occurred in millions of years and from which there will be no recovery for coral reefs and for many other natural systems on which humanity depends. Working group signatories Professor John Veron (Coral Reef Research) Dr Mary Stafford-Smith (Coral Reef Research), Prof. Ove Hoegh-Guldberg (University of Queensland) ]and 20 other eminent scientists including Sir David Attenborough FRS (working group co-chair)].

Polya's 3 Laws of Economics mirror the 3 Laws of Therrnodynamics of science and are (1) Price minus COP (Cost of Production) equals profit; (2) Deception about COP strives to a maximum; and (3) No work, price or profit on a dead planet. These fundamental laws help  expose the failure of neoliberal capitalism in relation to wealth inequality, massive tax evasion by multinational corporations, and  horrendous avoidable deaths from poverty and pollution culminating in general ecocide, speciescide, climate genocide, omnicide and terracide.

Carbon Debt:

Carbon Debt reflects the inescapable future cost in today's dollars of fixing the remorselessly increasing climate damage. Carbon Debt  is the historical contribution of countries  to the carbon pollution of the atmosphere and can be variously expressed as Gt CO2-e (gigatonnes or billions of tonnes of CO2-equivalent) or in dollar terms by applying a Carbon Price. Thus leading climate economist Dr Chris Hope from 90-Nobel-Laureate Cambridge  University has estimated a damage-related Carbon Price in US dollars of $150 per tonne CO2-e (see Dr Chris Hope, “How high should climate change taxes be?”, Working Paper Series, Judge Business School, University of Cambridge, 9.2011: http://www.jbs.cam.ac.uk/fileadmin/user_upload/research/workingpapers/wp1109.pdf  ).

The World added 350 Gt C (1285 Gt CO2) to the atmosphere in 1751-2006 (see James Hansen, “Letter to PM Kevin Rudd by Dr James Hansen”, 2008: http://www.aussmc.org.au/documents/Hansen2008LetterToKevinRudd_000.pdf ) and currently adds a further 64 Gt CO2-e annually (see Robert Goodland and Jeff Anfang, “Livestock and climate change. What if the key actors in climate change are … cows, pigs and chickens?”, World Watch, November/December 2009: http://www.worldwatch.org/files/pdf/Livestock%20and%20Climate%20Change.pdf ).

The World  has a 1751-2006 Carbon Debt of     350 Gt C x (3.67 Gt CO2/Gt C) x $150 per tonne CO2-e = $193 trillion plus a 2007-2015 Carbon Debt of (64 Gt CO2-e /year) x  ($150 /t CO2-e) x 8 years  = $76.8 trillion or a total 1751-2015 Carbon Debt of $270 trillion (about 3 times the annual world GDP of $85 trillion)  that is increasing by about 64 Gt CO2-e/year  x ($150 /t CO2-e)  = $9.6 trillion/year or about $10 trillion each year.

By way of a national example, Australia is a world-leading annual per capita  GHG polluter with a 1751-2006 Carbon Debt of 5.9 Gt C x (3.67 Gt CO2-e/Gt C) x ($150 /t CO2-e) = $3.2 trillion plus a 2007-2015 Carbon Debt of  2 Gt CO2-e/year  x ($150 /t CO2-e) x 8 years  = $2.4 trillion i.e. a total 1751-2015 Carbon Debt of $5.6 trillion (A$7.2 trillion) that is increasing at 2 Gt CO2-e /year x ($150 /t CO2-e) = $300 billion (A$385 billion) per year. Thus Australia (population 24 million) with 0.34% of the world's population has 2.1% of the world's Carbon Debt. The Australian Carbon Debt will have to be paid by the young and future generations and for under-30 year old Australians is increasing at about $30,000 (A$38,500) per person per year, noting that the annual Australian per capita income is about $65,000 (A$83,000) (see Gideon Polya, “2015 A-to-Z  alphabetical list of actions and advocacies for climate change activists”,  Countercurrents, 14 January, 2015: http://www.countercurrents.org/polya140115.htm ).
