So the Copenhagen summit did not deliver any hope of substantive change, or even any indication that the world's leaders are sufficiently aware of the vastness and urgency of the problem. But is that such a surprise? Nothing in the much-hyped runup to the summit suggested that the organizers and participants had genuine ambitions to change course and stop or reverse a process of clearly unsustainable growth.

Part of the problem is that the issue of climate change is increasingly portrayed as that of competing interests between countries. Thus, the summit has been interpreted variously as a fight between the "two largest culprits" - the U.S. and China - or between a small group of developed countries and a small group of newly emerging countries (the group of four - China, India, Brazil and South Africa), or at best between rich and poor countries.

The historical legacy of past growth in the rich countries that has a current adverse impact is certainly keenly felt in the developing world. It is not just the past: current per capita greenhouse gas emissions in the developed world are still many multiples of that in any developing country, including China. So the attempts by northern commentators to lay blame on some countries for derailing the result by pointing to this discrepancy are seen in most developing countries as further evidence of an essentially colonial outlook.

But describing this as a fight between countries misses the essential point: that the issue is really linked to an economic system - capitalism - that is crucially dependent upon rapid growth as its driving force, even if this "growth" does not deliver better lives for the people. So there is no questioning of the supposition that rich countries with declining populations must keep on growing in terms of GDP, rather than finding different ways of creating and distributing output to generate better quality of life. There is no debating of the pattern of growth in "successful" developing countries, which has in many cases come at the cost of increased inequality, greater material insecurity for a significant section of the population and massive damage to the environment.

Since such questions were not even at the table at the Copenhagen summit - even a "successful" outcome with some sort of common statement would hardly have been a sign of the kind of change that is required. But this does not mean that the problem has gone away; in fact, it is more pressing than ever.
