PAULINE'S ZOOM PRESENTATION
Pauline Witzke (Hons. B. Sc, Earth Sciences, University of Waterloo 1982) is a retired geologist who lives in Belleville, Ontario. Her career included oil and gas exploration, environmental geology, and nuclear power operations.
Her talk summarizes global warming events from the geologic past:
How high atmospheric greenhouse gasses got
How much the global average temperature increased
How they affected life on earth
How long they lasted
Why they ended
Pauline then compares these events to the global warming we are now experiencing, and includes how close we are to the point of no return, when that might happen, and how we can stop it.
