This call to action comes from Peter Singer, Australian philospher and bioethicist who is a professor at Princeton, and the University of Melbourne.  Over the weekend, his fantastic op-ed calling people the world over to take action on October 24th showed up in papers in Korea, Lebanon and Ecuador – testament to just how fast information can spread these days, and just how widespread this campaign has become with actions now in over 161 countries.  Here are the links to the different papers, and the text below:

Un Día para hacer justicia al planeta, Oct. 24: A day for planetary justice (Korea Herald), October 24: A day to stand up for planetary justice (The Daily Star, Lebanon)

PRINCETON: What we are doing to our planet, to our children and grandchildren, and to the poor, by our heedless production of greenhouse gases, is one of the great moral wrongs of our age. On October 24, you can stand up against this injustice. October 24 is 350 Day. The name comes from the number of parts per million of carbon dioxide in the atmosphere that, according to Jim Hansen, perhaps the world’s leading climate scientist, we should not exceed if we are to avoid potentially catastrophic climate change. It is a measure of the seriousness of our problem that CO2 is already at 386 parts per million (ppm), and is rising by two ppm each year.

The need to cut greenhouse gases has become increasingly clear as predictions of global warming – denounced as “alarmist” when they were first made just a few years ago – have repeatedly turned out to have been too conservative. We are approaching a point of no return, at which feedback loops will kick in and continue to warm the planet, no matter what we do.

The melting of arctic ice is one example. Four hundred years ago, explorers sought the legendary “Northeast Passage” across the north of Europe and Russia to China. They found the arctic ice impenetrable, and soon gave up their quest. This year, commercial vessels successfully navigated the Northeast Passage.

That is one of many recent dramatic signs that our climate is changing and that our planet is warmer than it has been for a very long time. But ice-free arctic waters are more than a symptom of global warming. They are themselves a cause of further warming: ice and snow reflect the sun’s rays.

An ice-free surface absorbs more warmth from the sun than one covered in snow or ice. In other words, our greenhouse gas emissions have, by causing enough warming to melt the arctic ice, created a feedback loop that will generate more warming, and melt more ice, even if we were to stop emitting all greenhouse gases tomorrow.

Other feedback loops pose a similar danger. In Siberia, vast quantities of methane, an extremely potent greenhouse gas, are locked up in what used to be called “permafrost” – regions in which it was assumed that the ground was permanently frozen. But areas that used to be frozen are now thawing, releasing methane and thus contributing to further warming – and to further thawing, which releases more methane.

Developing nations are grasping just how outrageous the current distribution of greenhouse-gas emissions really is. At the United Nations Summit on Climate Change in September, President Paul Kagame of Rwanda pointed out that, while developed nations outside Africa are almost entirely responsible for the problem, its greatest impact will probably be on Africa, which has few resources to cope with the challenge.

Kagame then suggested giving every country an annual per capita quota for CO2 emissions, and allowing developing countries that are below the quota to trade their excess quota with countries that are above theirs. The money that developing countries would receive for this would not be aid, but rather a recognition that the rich nations must pay for something that in the past they simply appropriated: far more than their fair share of our atmosphere’s capacity to absorb our waste gases.

Sri Lanka took a similar stance, using studies from the UN Intergovernmental Panel on Climate Change to calculate that in 2008, environmentally permissible carbon emissions totaled no more than 2,172 kilograms per person. In fact, the world’s per capita emissions were 4,700 kilograms, or more than double the permissible limit.

But, while emissions in the rich nations were far above the permissible limit, Sri Lankan emissions were, at 660 kilograms, well below it. As Sri Lanka’s government pointed out, “That means low-emitting countries like us could not emit more because our space has already been exploited by developed or global heavy polluting countries without our consent.”

This situation is an injustice of vast proportions, reminiscent of – and arguably much worse than – the now-repudiated colonialism of the Western powers in the 19th century. The task of remedying it must begin at the meeting on climate change that will be held in Copenhagen in December.

Many political leaders have expressed support for strong action on climate change, but what most of them regard as “strong action” will not be enough to get us back below 350 ppm. In some countries, including the United States, there are major political obstacles to taking even modest steps.

On October 24, people in nearly every country will be taking action to raise awareness of the need for an international treaty to bring our atmosphere back to 350 ppm of CO2. There will be climbers hanging banners high in the Himalayas, where the glaciers are melting, and scuba divers at Australia’s Great Barrier Reef, which is threatened by climate change.

Churches will ring bells 350 times, 350 cyclists will circle towns, and, in many places, 350 trees will be planted. At www.350.org you can find out what is happening near you and join in, or put your own idea online. But don’t just sit back and hope that others will do enough to make an impact. One day your grandchildren will ask you: what did you do to meet the greatest moral challenge of your time?
