Under a Green Sky Global Warming the Mass Extinctions of the Past and What They Can Tell Us About Our FutureOntologist Peter D Ward fresh from helping prove that an asteroid had killed the dinosaurs turned to the Permian problem and he has come to a stunning conclusion In his investigations of the fates of several groups of mollusks during that extinction and others he discovered that the near total devastation at the end of the Permian period was caused by rising levels of carbon dioxide leading to climate change But it's not the heat nor the humidity that's directly responsible for the extinctions and the story of. What's the worst case scenario that could happen in the future because of global warming This book will tell you Paleontologist Peter D Ward has spent his entire academic career studying the effects of past climates on the earth's many life forms and in my opinion he speaks with great authority when projecting these findings into the future Written almost like a detective novel Ward leads you through the latest scientific discoveries about past climates and the mechanisms that produced them Some of the conclusions he reaches are truly disturbing and could almost be read as a call to action for those of us aware of this momentous problem to avert the worst ravages of the climate change that is already upon us The green sky referred to in the book's title represents a lifeless planet earth that could result if global warming is left uncheckedI read this book after reading Climate Wars The Fight for Survival as the World Overheats because the author of that book referred to this one so often to support his own conclusions Climate Wars lays out several near future scenarios that could result from unchecked global warming and Under a Green Sky completes the picture by showing how the present trends of CO2 accumulation the primary mechanism of climate change can lead to a nightmarish longer term future
