Waking the Giant, the dynamic world beneath our feet. - 7 weeks
S 2020

Description

The ground beneath our feet may seem safe and solid but earthquakes, volcanic blasts and other hazardous natural phenomena leave no doubt that this isn't the case.  The earth is a dynamic planet of shifting tectonic plates that is responsive to change, particularly when there is a dynamic climate transition.  Over the past 20,000 years, the earth has undergone an astonishing transformation from  frigid wasteland to the temperate world upon which our civilization has grown and thrived.  The disturbing fact is that there are clear signs that human-induced climate change is awakening the slumbering giant on which we live.

 The core book is delightful, easy to read and wonderfully informative.
