Top climate scientists in the top scientific journal Nature recently stated that we have exceeded crucial planetary boundaries beyond which we are at high risk of unacceptable environmental change. These and other top climate scientists and biologists are stating clearly that the atmospheric CO2 concentration must be urgently returned to 300-350 ppm for planetary safety. Unfortunately, World governments are ignoring the science and are committed to increasing CO2, evidently not understanding that there can be no negotiation with the laws of Physics and Chemistry.
An Australian husband and wife with homeopathic beliefs were recently jailed for the manslaughter of their horribly neglected child. Accountability must also apply to all people who are ignoring scientific advice and international law and are complicit in the carnage of US wars (9-11 million excess deaths in US wars, 1990-2009, including 4 million infants) and in the worsening climate genocide (that will kill 10 billion people, including 6 billion infants). This inescapable legal, business, political and electoral Accountability for war crimes and climate crimes is detailed in a Letter being transmitted to all Federal MPs in climate criminal Australia (a world leader in annual per capita greenhouse gas pollution) and indeed to everyone so that, unlike many Germans in 1945, they cannot say “we didn’t know”.

The key moral imperative of the Synthesis Report is “Inaction is inexcusable”.
In December 2009 the governments of the world will discuss their responses to the climate emergency facing the planet. Civilized, educated , humanitarian people dread the outcome which is likely to be grossly deficient. However in March 2009 2,500 participants (mostly climate science researchers) gathered for the scientific Copenhagen Climate Change Conference (“Climate Change, Global risks, challenges & decisions”, Copenhagen 10-12 March, 2009, University of Copenhagen, Denmark).
The must-read Synthesis Report from the March 2009 Copenhagen Climate Change Conference (“Climate Change, Global risks, challenges & decisions”, Copenhagen 10-12 March, 2009, University of Copenhagen, Denmark) has just been released.
This is a vital synthesis of current climate science from the March 2009 Copenhagen Climate Change Conference that involved 2,500 professional participants, most of them climate science researchers. All were welcome and the program and abstracts of the papers presented are available here.
The key moral imperative of the Synthesis Report is “Inaction is inexcusable”.

The Australian Green senator Christine Milne, the first female leader of a political party in Tasmania’s history, delivered this speech to the Australian National Press Club this past week.
Key quote from the speech:
“The truth is the climate nightmare is real and happening now. We are destroying the Great Barrier Reef, Kakadu and the snow caps. We are eroding our beaches, and our coastal cities will face managed retreat due to sea level rise. We are drying our food bowl, the Murray Darling, beyond repair, jeopardising rural communities and our food security.
Many of our Asia Pacific neighbours are struggling with rising seas and extreme weather which threatens a refugee crisis beyond anything we’ve ever seen.
The Himalayan glaciers, which feed all the major rivers of Asia — the Ganges and Brahmaputra, the Mekong, the Yellow and Yangtze — are melting away. Once they are gone, a third of the world’s people face a parched, hungry and, most likely, violent future.”
For what we have to do urgently – install renewables, return air CO2 to 300 ppm, return carbon as biochar to the soil, re-afforestation and cessation of carbon pollution and deforestation – see Climate Emergency Facts and Required Actions and 300.org – return atmosphere CO2 to 300 ppm.

“Nevertheless the climate sceptics are unfazed and essentially all governments around the world are committed to continuing to increase atmospheric carbon dioxide…”
An overwhelming global scientific consensus says that man-made global warming is happening NOW. Indeed for the latest see the report from President Obama’s science advisers that states that massive climatic disruption is already affecting the United States and that projects that the average U.S. temperature could rise by as much as 11 degrees Fahrenheit by the end of the century (see “White House: climate change damage happening now. Obama’s first global warming report most dire yet: Ill effects already here, will get worse”). Thus White House report report co-author Anthony Janetos of the University of Maryland:
“There are in some cases already serious consequences. This is not a theoretical thing that will happen 50 years from now. Things are happening now.”
Nevertheless the climate sceptics are unfazed and essentially all governments around the world are committed to continuing to increase atmospheric carbon dioxide (CO2) concentration above the present level of circa 390 parts per million (ppm) to even more dangerous levels.
In contrast, in climate criminal Australia (one of the world’s worst annual per capita greenhouse gas polluters) climate activists and leading climate scientists are calling for urgent reduction of atmospheric CO2 to 300 ppm. The Australia-based Climate Emergency Network, the Canberra Climate Action Summit (over 140 Australia-wide climate action groups), the influential Yarra Valley Climate Action Group and 300.org all say – informed by the latest science from America’s Dr James Hansen (NASA GISS), Australia’s Professor Barry Brook (climate science, University of Adelaide) and others – that for a safe and sustainable existence for all people and all species the atmospheric CO2 of our warming-threatened planet must be urgently reduced from the current circa 390 ppm to 300 ppm (click here for details and documentation).

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.
