Episode 598 More on Iron Salt Aerosol
projectsavetheworld's podcast
Oswald Petersen is working on an intervention to reduce methane from the atmosphere with iron salt. Peter Fiekowsky, in California, is endorsing this project with enthusiasm. They explain the current plans to climatologist Paul Beckwith and Canadian Pugwashites Adele Buckley and Robin Collins. The new plan is to use airplanes to disseminate the iron instead of their original notion, towers.

Episode 595 Thinning Cirrus Clouds
projectsavetheworld's podcast
David Mitchell (and his colleague Ehsan Erfani) are pointing out that the high cirrus clouds are like a blanket warming the planet. If we poke holes in the blanket, we release heat. Likewise, by seeding the cirrus clouds in the winter at the poles, we can release excess heat from our world. For the video, audio podcast, transcript and comments:

Episode 594 It's time to Geoengineer Climate
projectsavetheworld's podcast
Gwynne Dyer's new book, Intervention Earth, is really about geoenginering and the urgency of studying the numerous proposals for cooling the planet faster than by simply reducing carbon emissions. For several years, Dyer and his wife Tina Viljoen have been filming numerous interviews with experts on climate, aware earlier than most other people that the only possible way to avert global catastrophe would eventually depend on the application of some such measures at scale. At last, that reality is becoming recognized by scientists, but much more needs to happen to change public opinion in time....

Episode 592 Tiny Green Things
projectsavetheworld's podcast
Ricardo Letelier and Peter Fiekowsky know that phytoplankton created the oxygen in our atmosphere. Now maybe they can help us again by removing CO2 from the atmosphere and sending it to the ocean depths. But do phytoplankton respire it out too quickly for that to work? And would a good new volcano do what Mt. Pinatubo did: cool the planet by feeding the phytoplankton and making them multiply and take our more carbon dioxide?

info_outlineEpisode 367. Claudia Wagner-Riddle is an agrometeorologist; she studies how agriculture affects climate change -- both the production of plants and animals. The quality of soil is a key factor. Various essential bacteria in the soil produce nitrous oxide and other compounds of nitrogen, which plants require, but which affect air and water negatively in several respects. By recycling animal manure, farmers can adequately replenish the nutrients in their soil, but about half of the people on the planet today are alive because they eat food produced by synthetic fertilizers, which have been seriously mis-used and are causing climate problems as well as other environmental stresses. And the ruminant animals (notably cattle and dairy cows) also emit methane in the process of digesting grass. These are complicated problems to solve, and Wagner-Riddle does not favor the widespread proposal to end the maintenance of cows.
