http://www.futurescenarios.orgI just found this remarkable web site by David Holmgren, a permaculture guru. It's an analysis of what could happen as PO and CC intersect. He's done a thorough, objective, balanced job. The analysis culminates in four scenarios based on the speed of impact of the two problems (from slow oil depletion/slow climate change to fast oil depletion/fast climate change). In each scenario he makes a very reasonable case for the resulting structural/cultural/political outcome.
The fact that he examines four quite different scenarios insulates him against the charge of merely projecting his personal cornucopian/doomer inner landscape onto the world of the future.
One of the things that struck me quite hard is his application of Howard Odum's emergy analysis to the possible energy decline of the next 40 years. It turns out that even the story I've been telling (of a 30% decline in primary energy supply by 2050) drastically overstates the amount of
net energy we might have available then to do the work of civilization. His calculations indicate a drop of 40% in net energy, meaning we could only have 40% (i.e. 60% of 70%) of today's net energy to work with by then.
Here are some excerpts:
The simultaneous onset of climate change and the peaking of global oil supply represent unprecedented challenges for human civilisation.
Global oil peak has the potential to shake if not destroy the foundations of global industrial economy and culture. Climate change has the potential to rearrange the biosphere more radically than the last ice age. Each limits the effective options for responses to the other.
The strategies for mitigating the adverse effects and/or adapting to the consequences of Climate Change have mostly been considered and discussed in isolation from those relevant to Peak Oil. While awareness of Peak Oil, or at least energy crisis, is increasing, understanding of how these two problems might interact to generate quite different futures, is still at an early state.

Much faith in both growth and steady state scenarios rests on the observation that human ingenuity, technology, markets and social capital are at least as important in shaping history as raw energy and resources. The stunning power and spread of computers and information technology into all sectors of industrial society is seen as much a product of human capital as it is of natural capital. The rise of the service economy promised continued economic growth without using more energy and materials. But these service economies and the human capital that helped create them were themselves created through the flows of energy and resources. For example, mass education, and especially mass tertiary education, is a very expensive investment in technical capacity and social capital that has been possible because of economic wealth from the extraction of cheap fossil energy and non-renewable resources.

For a minority of intellectuals and ordinary citizens, unimpressed by the likelihood of Techno Explosion or Techno Stability, the logical future seems to be some kind crisis leading to implosion and the collapse of civilisation. The old adage “what goes up must come down” still has some truth but several factors lead to people jumping to the conclusion that the Collapse scenario is inevitable without thinking about the possibilities of Descent.

This exploration of energy descent scenarios has been an organic one which began with a didactic intention to highlight how large scale energetic and environmental factors shape history more than ideologies and the heroic actions of individuals. But my purpose was to empower those committed to ecological values and social justice to be effective in their quest to create the world we want, rather than just resist the world we don’t want. Finally it has become about telling a story that can help bring that world to life, an apparent contradiction to the premise I began with. Although the primary lesson about the large scale forces that control the course of history may be true for the long periods of stability, during periods of ecological and cultural chaos, small groups of people have been instrumental in those transitions.
IMO this is a remarkably balanced and insightful look at the Converging Crisis, and will amply reward the time it takes to read it.
