Anthropogenic activities have altered the natural climate system. Changing climate alters human activities. This feedback loop is nonlinear and effects are amplified in unknown ways that may lead to unexpected tipping points both in global climate and viability of society. We must find ways, and soon, to adapt to changing climate to sustain social systems. Human systems are coupled to, and indeed dependent upon, natural systems; we need to conduct climate change research that integrates studies of both systems. And we need to apply what we learn about these systems to decisions that get made.

Structure contours drawn on acoustic basement define three basins within the province; the basins contain strata 10 to 15 km thick and underlie more than 2 45,000 km (11 million acres) of the Bering Sea shelf. Tertiary mudstone dredged from the continental slope averages more than 0.33 percent (range of .33 to .88) organic carbon, and Cretaceous mudstone along the continental slope in Pribilof Canyon contains as much as 1 percent organic carbon. However, these mudstones may not be correlative with the lower Intense storms produce exceptionally large waves which are not only capable of eroding bottom sediments, but also are dangerous to surface structures and vessels. Gas-charged sediment, present throughout a large part of the basin, has reduced strength and bearing capacity as compared to strength of gas-free sediment. Volcanic activity is a hazard of low probability. Migratory pack ice is a yearly occurrence and could pose a significant problem during years of heavy concentrations. 64 62 0 Multichannel Track Lines Figure 2.

To compose this concept, “hardware building blocks” have been used, i.e., experiences from past decades with ecovillages and garden cities. For “software building blocks,” we have used the recently formulated visions on the relation between climate change, citizen participation, social learning, and non-hierarchical governance. Each of these building blocks is described by one of the co-authors. At the end of the article, as a synthesis of conclusions of both theoretical and practical nature and through the case study of experiences with starting the first prototype in Khajuraho, India, a general structure is formulated for supporting multiple co-learning engagements on the local level of cities and communities in east and west, north and south. The hypothesis is that the integration of these learning experiences may solve global social, economic, and ecological crises on local scales. The outcome of this long-term and multi-level learning process is called “global knowledge,” and the cities in which such learning takes hold are global knowledge cities.
