The Ottawa Centre is comprised of about 90 CMOS members. The Centre holds monthly meetings downtown from September through May.  Our meetings are open to members and the public.  Meetings start with lunch followed by a presentation by an invited speaker and discussion. Occasionally our meetings are joint with partner groups or societies.  About every ten years, the Ottawa Centre hosts the annual CMOS Congress.

Outreach activities aimed at high school, university and post graduate students are a priority for the Ottawa Centre. We judge and provide prizes at regional science fairs in Ottawa and Gatineau.


Upcoming Luncheon Meeting - Tuesday 24 October 2017

SPEAKER:  Geoff Strong, Atmospheric Scientist

:  Global Warming Impacts - Present and Future Scenarios

ABSTRACT:  While Arctic regions have been warming faster than anywhere else on Earth, the impacts of global warming have been most severe over the sub-tropics where about half the human race lives. Most disturbing of all is the desertification of the sub-tropics caused by the expansion of Earth's great deserts, leading to severe prolonged droughts and famines rivalling any in recorded history.  

Conditions in those regions most seriously affected by global warming, particularly Africa and the middle east, and how this has translated into climate refugees, will be described. The talk will include speculation on the dynamics that lead to desertification in many regions, but which also allow heavy rains and flooding in immediate adjacent areas. Finally, comparison will be made of today's conditions with the reality of future scenarios, and why action on solutions to the global problem must start at the grass roots, with individuals. This may finally be happening, but the question remains: is it too late?

About the presentation: "Humanity faces a myriad of ecological, economic, and social problems, many of which have no easy or obvious solution.  Every event has many antecedents, and we usually attribute our problems or the occurrence of catastrophic events to the most immediate and obvious antecedents, while overlooking the role of population growth as a major driving factor in creating the conditions for the antecedent events to occur."

About the speaker: Madeline Weld is the president of the Population Institute Canada (PIC), an organization concerned with the implications of human population growth for all life on Earth. She has a B.Sc. in zoology from the University of Guelph and an M.S. and Ph.D. in physiology from Louisiana State University in Baton Rouge. She worked at the University of Ottawa for many years between 1984 and 2001.  Now retired, she worked in the Food Directorate of Health Canada from 2001 to 2014.  Madeline is also a co-editor of Humanist Perspectives, a quarterly Canadian magazine.
