    For the first time, climate scientists from across the country have successfully incorporated the nitrogen cycle into global simulations for climate change, questioning previous assumptions regarding carbon feedback and potentially helping to refine model forecasts about global warming. The results of the experiment at the Department of Energy's Oak Ridge National Laboratory and at the National Center for Atmospheric Research are published in the current issue of Biogeosciences. They illustrate the complexity of climate modeling by demonstrating how natural processes still have a strong effect on the carbon cycle and climate simulations. In this case, scientists found that the rate of climate change over the next century could be higher than previously anticipated when the requirement of plant nutrients are included in the climate model. ORNL's Peter Thornton, lead author of the paper, describes the inclusion of these processes as a necessary step to improve the accuracy of climate change assessments.

  • The most recent UN report on climate change predicts that greenhouse gases already in circulation have committed the planet to a warming of 2.5 degrees. “No matter what we do today to reduce emissions, the planet will still heat up,” says Ramanathan. But, through a quirk that Ramanathan has spent 10 years uncovering, the planet actually manifests only ¼ of the warming it should based on these climate models. Air pollution, specifically brown clouds from burning biomass, Ramanathan has learned, act as a global warming mask, reducing sunlight on the ground. “On the one hand, it has protected us, but also prevented us from seeing the full blast of the greenhouse effect,” he says. “One of the dumbest things we can do is to reduce sunlight,” because it reduces ocean evaporation, which cuts down on rainfall, and shifts weather systems everywhere, shrinking harvests and glaciers.
  • We are left with “Faustian bargains,” says Ramanathan. If we cut airborne pollutants such as sulfur, the mask will drop, temperatures rise rapidly, and climate tipping elements come into play. Curing one ill causes another. Any plan for “dismantling the experiment we have done with blankets, mirrors and dust must be done as carefully as dismantling a nuclear device.”

  • However, convincing northern consumers of the need for a new paradigm and new lifestyles, given the impossibility of endless growth on a limited planet, will not be an easy task.[8] A synthesis, of elements of sometimes overly holistic indigenous wisdom and of excessively compartmentalized western science, seems to me the a fruitful combination to provide guidance for a way out of the current crises which threaten the planet, our Mother Earth.

      Dualist indigenous/western knowledge paradigm is partially useful at best.  Looking at relations of power and voice is more useful.  See Edelman's "Peasants Against Globalization"
  • the phrase “to live well but not better” (than others, or at the cost of others) is potentially confusing in English since “well” and “better” are similar if used to denote qualitative vs quantitative meaning. Language and culture are crucial elements if we are to convince others to understand and then follow this “dictum”. For example, English is a language based largely on nouns, while Anishinabe languages are dominated by verbs, resulting in cultures which focus respectively on objects versus process[12], with a resultant tendency to objectivize or integrate nature.[13] This may in part explain the domination of the planet today by English dominated cultures and may make the task of undoing this domination extra difficult.
  • Ecuadorian economist Pablo Davalos[16] provides a brief survey of the evolution of dependency, Marxist, world system and neo-liberal classical economics to show how we have arrived at a state of economic autism. He concludes that “Of the alternative concepts that have been proposed, the one that presents more options within its theoretical and epistemological framework to replace the old notions of development and economic growth, is Sumak Kawsay, good living.”

  • The creation of “autonomous” zones of power in Chiapas, with parallel institutions of governance are said to have brought significant political transformation, but some say they have not yet created a viable model of economic autonomy for poor peasants.[22] Others cite civil – military tensions in the Juntas of Good Governance as reducing local autonomy.[23] Some feel that internal political organization has taken priority over social and economic improvements and weakened earlier efforts to reform the broader Mexican state and guarantee indigenous rights of self-determination.[24] Nevertheless, the Zapatista carcoles are models of governance which include many elements implicit in the ecosocialist and degrowth paradigms and further research on these experiences is sorely needed.
  • The protection and preservation of balance in the natural world, including all its living beings, is a primary goal and need of our proposal. Mother nature has inherent rights to exist on the Earth in an undiminished healthy condition.

    In its efforts to exert some political influence on solutions to the current world financial and climate crises the nascent international ecosocialist movement should direct some attention to a synthesis of the western ecosocialist discourse with the growing Latin American indigenous discourse that is making exciting progress, albeit in fits and starts, toward an international charter for the protection of the planet, Mother Earth, and all forms of life on it.
