Peter Kalmus

Dr. Peter Kalmus is a scientist studying clouds and climate change at NASA's Jet Propulsion Laboratory (speaking on his own behalf). He holds a PhD in physics from Columbia University. Concerned about global warming, Dr. Kalmus cut his emissions to below a tenth of the US average, and found that this made his life more interesting, satisfying, and joyful -- not less. He now does everything he can to spread this message and to help humanity transition away from fossil fuels. He believes that the problem is not only technological or scientific, but also spiritual: it calls humans to set aside the notion that we are exceptional within the web of life, and instead to live, gratefully, in alignment with the biosphere.
