Can humanity trust capitalism with its future? In 1988, seven years before the United Nations first conference on global warming was held, former NASA scientist Dr. James Hansen testified before the US Congress that scientific evidence affirmed that the burning of fossil fuels was causing global warming. Since then three primary capitalist sectors – financial institutions, fossil fuel/energy firms and vehicle manufacturers have ignored climate concerns. Trillions of dollars have been invested in the fossil fuel economy accelerating global warming. Imagine what could have been possible since 1988 had the capital instead been invested in avoiding the crisis. The United States and many other nations' economies could already have been largely powered by wind, solar, geothermal and other renewable energy sources. Imagine having a healthier and cleaner environment. Imagine we are well on our way to abating global warming. Climate Chaos, Global Poverty and Capitalism shows such a future is still possible but it will require global cooperation and a new economic model. Seven key relationships, as listed below and discussed throughout this work, frame the economic criteria and climate math necessary to slow and reverse climate chaos. These relationships are interdependent. Thus without addressing all of them the climate crisis cannot be resolved. • Democratic direction of private investment capital and production to abate the crisis. • Curtail overall consumption in well-off nations. • Redistribute investment and production to end global poverty. • Degrowth: reduce unnecessary consumption to save energy and resources. • Move toward a global steady state economy. • Shorten the work year and work week to share jobs as steady state economy develops. • Initiate global negotiations to demilitarize all the world's economies. Climate Chaos argues that humanity will need to consider ending the rule of capital and implementing a People's Plan A based on socialist principles. The time to offer such a competing vision is now and not after we find that capitalism fails to do the right thing. As the struggle for a habitable planet unfolds a socialist economic model can act as a beacon for an ecological and economically sound visionary alternative.
