Some excerpts from his paper:

The German Energy Watch Group points out that the world’s proven and possible reserves of uranium would be able to support the current level of demand for uranium for at most seventy years and the world could face uranium supply shortages after about 2020.

Worse, recent studies reveal that taking into account emissions in land development and soil erosion, fuels made from biomass actually emit more greenhouse gases than conventional petroleum.

The mainstream environmental movement, as far as its social composition is concerned, mainly consists of people who belong to the upper middle class in a capitalist society. They include the university professors, engineers, technicians, managers, financial analysts, and other professionals. Although they typically do not own significant amounts of the means of production, they play important managerial and technical functions for the capitalists and enjoy substantial material privileges relative to the working class.

From a purely technical point of view, the most simple and straight forward solution to the crisis of climate change is immediately to stop all economic growth and start to downsize world material consumption in an orderly manner until the greenhouse gases emissions fall to reasonable levels. This can obviously be accomplished with the existing technology. If all the current and potentially available de-carbonization technologies are introduced to all parts of the world as rapidly as possible, the world should still have the material production capacity to meet the basic needs of the entire world’s population even with a much smaller world economy.
