This blog focuses on the natural world, with a particular emphasis on the twin sides of our fossil-fuel addiction: (1) global climate change and (2) energy decline. Because these phenomena impact every aspect of life on Earth, specific topics range widely, and include philosophy, evolution, economics, humanity, politics, current events, and many aspects of the human condition.
