The Great Dying wiped out at least 90% of the species on Earth due to an abrupt rise in global-average temperature about 252 million years ago. The vast majority of complex life became extinct. Based on information from the most conservative sources available, Earth is headed for a similar or higher global-average temperature in the very near future. The recent and near-future rises in temperature are occurring and will occur at least three orders of magnitude faster than the worst of all prior Mass Extinctions. Habitat for human animals is disappearing throughout the world, and abrupt climate change has barely begun.  The Real Truth About Health Conference, 2016 published as CC BY US 3.0 by The Real Truth About Health, 2018.
