Geoengineering – An overview of potential Earth cooling technologies
-Join us for this overview of the Geoengineering concept and some of the leading technologies being studied. Geoengineering describes technologies that cool the Earth by reflecting the sun’s energy back into space or allowing heat from the Earth to escape the Earth’s atmosphere. While not a substitute for carbon emissions reductions, or carbon sequestration, some researchers claim that these technologies could be critical to avoid the catastrophic consequences of global heating and climate change.
Because these techniques involve complex interactions with the Earth’s energy balance, they are controversial and not yet well understood. Join us as we hear from Dr. John Perona on this important topic. He is author of From Knowledge to Power, a comprehensive handbook for both established and aspiring climate advocates. We will cover the following questions and more:
– What is the carbon cycle and how has mankind affected that cycle?
– How have these changes affected the Earths energy balance?
– What is Geoengineering and what problems does it attempt to solve?
– How does Geoengineering differ from other climate technologies?
– What are the main technologies being considered within Geoengineering?
– What are the potential benefits and risks of these technologies?
Dr. John Perona PhD, JD, Professor at Portland State University. John holds degrees in chemical engineering, biochemistry, and law, and is author of over 100 peer-reviewed articles. He teaches classes in synthetic biology, structure-function biochemistry, and metabolism and works to integrate science, law and policy for sustainability. He is the author of From Knowledge to Power, which Professor Katherine Hayhoe has called “A one-stop shop for anyone who wants to understand the fine details of climate science, past and future energy sources, and U.S. policies and political action to address the climate crisis.”
