How do astronomical rhythms affect the Earth's climate? Is it true that tiny changes in the heat balance of the Earth could plunge us back into full ice age conditions? Ruddiman Earth's Climate: Past and Future summarises the major lessons to be learned from 550 million years of climate changes, as a way of evaluating the climatological impact on and by humans in the 21st century.With startling new material on how the last major Ice Epoch could have hastened human evolution, "Ice Age" explains why the Earth was once covered in ice - and how that made us human. The Long Summer: How Climate Changed Civilization by Brian Fagan Brian Fagan traces the effects of climate change on civilisation over the past 15,000 years -- a period of prolonged global warming that has accelerated in the past 150 years -- and how civilisations have responded to, or been radically altered by, changes in environment. The book also looks ahead to possible effects during the next several centuries of fossil fuel use.
