ERAO PRESENTS ZOOM TALK ON CLIMATE CHANGE
Retired geologist Pauline Witzke asks the question: "How Close are we to the Point of No Return?"
Thursday, February 12, 2026 at 10:00 a.m.
(Participants are welcome provided they’ve paid their membership fee)
Pauline compares past geologic global warming events to current global warming, and includes how close we are to the point of no return, when that might happen, and how we can stop it.
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.
