In its 2001 report on global climate, the Intergovernmental Panel on Climate Change of the United Nations prominently featured the "Hockey Stick", a chart showing global temperature data over the past 1,000 years. The Hockey Stick demonstrated that temperature had risen with the increase in industrialization and use of fossil fuels. The inescapable conclusion was that worldwide human activity since the industrial age had raised CO2 levels, trapping greenhouse gases in the atmosphere and warming the planet.

From Joseph Romm, Chief Science Advisor for National Geographic's Years of Living Dangerously series and one of Rolling Stone's "100 people who are changing America," Climate Change offers user-friendly, scientifically rigorous answers to the most difficult (and commonly politicized) questions surrounding what climatologist Lonnie Thompson has deemed "a clear and present danger to civilization."

The greatest of all Civil War campaigns, Gettysburg was the turning point of the turning point in our nation’s history. Volumes have been written about this momentous three-day battle, but recent histories have tended to focus on the particulars rather than the big picture: on the generals or on single days of battle - even on single charges - or on the daily lives of the soldiers. In Gettysburg Sears tells the whole story in a single volume.

An epic story of science and technology at the very limits of human understanding: the monumental race to build the first atomic weapons.

Rich in personality, action, confrontation, and deception, The First War of Physics is the first fully realized popular account of the race to build humankind's most destructive weapon. The book draws on declassified material, such as MI6's Farm Hall transcripts, coded Soviet messages cracked by American cryptographers in the Venona project, and interpretations by Russian scholars of documents from the Soviet archives.
