Episode 608 Shall We Whiten Clouds?

David Henkel-Wallace, Franz Oeste, Clive Elsworth, Jeff Shrager, Peter Fiekowsky, and Rocio Herbert are all exploring the new discovery that clouds (the white ones that reflect sunlight back into space) also cool the planet in another way: by adding hydrochloric acid to the atmosphere, which has an independent cooling effect by destroying methane molecules. This may give us a new way of cooling the planet. Adele Buckley has a question. For the video, audio podcast, transcript and comments: https://tosavetheworld.ca/episode-611-thanks-to-chlorine.

Suzanne Reed and Doug Grandt belong to HPAC, an online webinar coalition of groups promoting technologies of climate repair. Lawrence Martin is a Cree environmental leader in Canada. We discuss the importance of including indigenous people in all phases of any planning for experiments on climate repair to be held in their territories.

Hugh Pope spent two years editing and publishing his late father's book about Athenian democracy. He became convinced that it is a superior form of governance that can be adopted even today, and indeed it is being used as citizens' assemblies, which government sometimes establish as a way of reaching consensus about issues that could not be addressed through regular representative institutions.

Hugh Hunt, Daniel Rosenfeld, and Steven Rogak are all engineers who are eagerly studying the potential. use of salt water spray to whiten clouds and reflect sunshine back into space, thereby reducing global warming. Adele Buckley is an engineer who is skeptical about the value of trying to keep the Arctic frozen at this time.

Jonathan Lauderdale is an oceanographer and ocean climate modeler at MIT, the alma mater of Peter Fiekowsky, who is now promoting research into the effects of sprinkling iron into oceans. It makes phytoplankton multiply, which removeds CO2 from the air, so that some of it sinks and sequesters carbon.

Barbara Leger talks about her peace work in Ukraine; Bill Geimer shares his desire for Canada to become more independent of the US. We hear about the situation in Kashmir, the purge of military leaders in Russia, and the use of platforms in the ocean to grow seaweed.

Flower Msuya, Ole Mouritsen, and Paul Carnell all are scientists studying various aspects of seaweeds. Also, Flower helps local producers, Ole experiments with cooking, and Paul helps governments save coastal ecosystems.

Laura Kahn is a leader in the field of "One Health," which studies the interdependence of human, veterinary, and environmental health issues. She authored a book about the increasing resistance of microbes to antibiotics and antiviral medications, mainly because of over-exposure.

John Nissen, Robert Tulip, Doug Grandt, and Robin Collins belong to webinar groups studying Stratospheric Aerosol Injection (SAI) as a way of cooling the planet by the same means as volcanoes do. Greg Evans is an expert on aerosols at U of Toronto. We discuss the pros and cons of attempting such a project at full scale.

Ulrike Lohmann and Blaz Gasparini are cloud scientists studying the potential climate effects of various geoengineering proposals – especially cirrus cloud thinning, stratospheric aerosol injection, and marine cloud brightening. Adele Buckley asks them whether the Arctic ice could be saved by brightening clouds in a warmer climate.
