Fixing the Sky

by Bryan Walker October 8, 2010

The notion that if it comes to the worst in climate change we can fall back on geoengineering  receives little credence in James Rodger Fleming’s new book Fixing the Sky: The Checkered History of Weather and Climate control. Fleming is a science historian and in the claims of some of today’s would-be climate engineers he [...]

Climate Wars

by Bryan Walker December 22, 2008

Gwynne Dyer’s new book Climate Wars explores the all-important political dimension of addressing climate change. Military history is Dyer’s speciality. One origin of this book was his dawning awareness that, in a number of the great powers, climate-change scenarios are already playing a large role in the military planning process. The other factor persuading him [...]
