Plows, Plagues, and Petroleum: How Humans Took Control of Climate
Plows, Plagues, and Petroleum: How Humans Took Control of Climate – Review
This book is NOT about global warming. At least, not directly about the global warming of the Industrial Age over which extremists from both environmental and industry/government groups loudly wrangle about. Ruddiman’s theme is global warming usually beginning far earlier — 8000 years earlier. His expertise is in paleoclimatology, analysis of the climate in long-past eras. He presents a extremely convincing case that originally starting about 8000 years ago, an greatly increased “unnatural” production of carbon dioxide from early human agricultural endeavors immediately began to measurably effect the earth’s climate (with the effect strengthened a few thousand years later by greatly increased methane emissions from rice farming). It is Ruddiman’s conclusion, very clearly presented and well supported with evidence, that this “extra” carbon dioxide has offset the “normal” global cooling that otherwise would have ended the present comfortable “interglacial” period and immediately plunged us once again into an period of severe glaciation.
