May 9, 2013: NOAA confirms that CO2 hits 400 ppm

The earth’s atmosphere hasn’t held this much CO2 since the Pliocene Epoch, an ancient era that ended more than 2 million years before the first Homo sapiens appeared.  Global CO2 levels hovered between 170 ppm and 300 ppm for ages until the Industrial Revolution, when a steady ascent began.  The U.N. Intergovernmental Panel on Climate Change estimates 450 ppm is when the worst effects of climate change will begin.

Consume less animal protein, or do so more responsibly?

Ecologist Allan Savory promotes holistic grassland management via a program of planned livestock grazing that “mimics nature,” claiming that it is the only way to stop desertification.  Savory believes that desertification is perhaps a greater contributor to climate change than fossil fuels.

Words Change the World

Frederick Douglass – prominent abolitionist, author, and orator – was born into slavery.  He used words to change the world, saying, “If there is no struggle, there is no progress … The struggle may be a moral one, or it may be a physical one, and it may be both … Power concedes nothing without a demand.  It never did and it never will.”
