The study of the science of climate change indicates that human activities are the most important drivers determining the physical and biological future of Earth. It demonstrates that failure to limit the production of greenhouse gases and aerosols and to minimize land use change will result in significant weather-related impacts that will not only be considered destructive from a human perspective but will likely result in the next great extinction of life on Earth, the Holocene or sixth extinction. Limiting these impacts and achieving Net Zero 2050 comes at a cost that requires support from all citizens of the global community, a support that is only possible if citizens are informed and confident in the underlying science.

Bio: David Manz has over forty-five years of experience working as a water/wastewater treatment process design engineer, water resources management specialist, climate change specialist, water resources engineer, hydraulics and irrigation engineer. He also has experience as an educator and researcher in colleges and universities and as an engineering consultant and senior corporate and engineering manager. From 2007 to 2020 he offered a course on the science of global warming and climate change at the University of Calgary which evolved into the ‘Guide to the Science of Climate Change’ that is available on the web and is a recommended reference for use in schools across Alberta. Among his many awards are the Alberta Order of Excellence for his development of the BioSand Water Filter, which he has made freely available to the developing world, and for his contribution to education on the science of global warming and climate change; and the Queen Elizabeth II Platinum Jubilee Medal, Province of Alberta.

Members of the public are welcome to attend (at a cost of $5).
