Climate change and the Anthropocene: both terms are commonplace, but their consequences are contested as their origins continue to be studied. Nobel Laureate Paul Crutzen's idea that humans came to exert a force for change in the earth's ecology from the late 18th century neatly conflated the onset of the Industrial Revolution in England with the start of the Anthropocene. Other dates have been proposed.

The latter is about much more than the increased emission of Green House Gases but these remain a key feature of these changes that may be altering the material flows that sustain human civilizations.

To a student of history, the issue of origins cannot be separated from when, where and how the pace, scope and nature of environmental transformation underwent epochal shift.

A peace among nations and between people requires a peace with the fabric of life. History has no silver bullet solutions but is vital to know how we came to this cross roads.
