Much sheer speculation has been written about the upcoming Copenhagen climate negotiations, and we will see much more over the next few weeks. What is this conference about, and what are the real issues at stake for the future of the world?

The conference in Copenhagen was set to negotiate a follow-up treaty to the Kyoto Accords, set to expire in 2012, a treaty that the Senate and the Bush administration refused to ratify or cooperate with. While China has recently passed the US as the largest emitter of global warming gases, the US is still far, far ahead of all other countries in per capita emissions, making US efforts a crucial aspect of whatever efforts the world makes.

The Kyoto Accords set aspirational guidelines for countries to shoot for as they worked to reduce carbon dioxide emissions. A large majority of the world’s countries ratified the Accords, and some made serious efforts to meet them, but few countries managed to do so. The European Union set up a carbon trading scheme, and several European countries have made large-scale investments in alternative renewable energy. Other countries only approached their targets due to decreased economic activity, primarily Russia.

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”.

Nicholas Stern endorses 350 ppm as “a very sensible long-term target”

By Simon Leufstedt on September 12th, 2009

Nicholas SternThis week Nicholas Stern, the British top climate economist and academic who is probably most known for the Stern Review, endorsed 350 ppm as “a very sensible long-term target.”

350 ppm, as in parts per million, the level scientists have identified as the safe upper limit for CO2 in our atmosphere. We are currently at 390 ppm and, according to the science, we need to get back to 350 ppm as soon as possible to be able avoid runaway climate change.

In an interview with a German newspaper Stern endorsed the 350 ppm target saying he “think it’s a very sensible long-term target.” Bill McKibben, environmental writer and founder of 350.org, writes:

“I think it’s a very sensible long-term target.” He went on to explain: “People have to be aware that is a truly long-term target. We have already passed 350ppm, we are at 390 ppm of Co2 and at 435 ppm of Co2-equivalents right now. It is most important to stop the increase of flows of emissions short term and then start the decline of flows of annual emissions and get them down to levels which will move concentrations of CO2 back down towards 350ppm.

Summary of the 2009 Copenhagen Climate Change Conference Synthesis Report

By Dr Gideon Polya on June 25th, 2009

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”.

Great power point lectures by top climate scientists and analysts

By Dr Gideon Polya on June 18th, 2009

“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).

350 or 300? Climate activists advocate 300 ppm CO2 for a safe planet for all people and species

By Dr Gideon Polya on June 9th, 2009

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.

Gore: We cannot negotiate with the facts, the truth and the consequences

By Simon Leufstedt on January 7th, 2009

During the embarrassing UN Climate Change Conference in Poznań, Poland, Al Gore held a speech where he said that the old and now “inadequate” climate change targets of 450 ppm (parts per million of CO2) had been made obsolete by new science (That’s what we and others have been saying for a while now). Gore said that the world should instead aim for a 350 ppm target.

The full transcript of his speech can be found below:

49 countries support a 350 ppm climate target in Poznań

By Simon Leufstedt on December 5th, 2008

I just got this email and video from 350, the global grassroots climate movement:

It’s 3 in the morning in Poland and I need your help with an experiment. Can you take 2 minutes watch an animation and help take over YouTube?

A little background: starting a week ago, a few members of the international 350.org team have converged for the annual UN Climate Conference. It’s a little crazy here–over 9,000 people representing 190 countries have gathered to negotiate our collective future. Things are changing by the hour, and there’s both bad news and good news to report.

The bad news first: lots of countries still don’t get it, and some (most notably, the EU) are using delay tactics to postpone action, squandering time that scientists say we simply do not have.

Now for the good news: over 49 of the least developed countries (that’s more than a quarter of the world’s nations) just announced support for a 350 target. This is AMAZING, as last year a 350 goal wasn’t even on the map. It’s testament to your hard work–and the very real threats these countries are facing right now–that we’ve come so far in such a short time.

100 Months Left Until Climate Change Runs Out of Control

By Simon Leufstedt on August 12th, 2008

100 Months Left Until Climate Change Runs Out of Control

In 100 months it will be too late to stop climate change. Then we have passed the “tipping point” where climate change will run out of control and leave us powerless to intervene. The message comes from the new campaign One Hundred Months from the New Economic Foundation (NEF), which wants to highlight this dangerous “tipping point.”

“If you shout “fire” in a crowded theatre, when there is none, you understand that you might be arrested for irresponsible behaviour and breach of the peace. But from today, I smell smoke, I see flames and I think it is time to shout. I don’t want you to panic, but I do think it would be a good idea to form an orderly queue to leave the building,” says Andrew Simms, policy director and head of the climate change programme at NEF.
