Episode 588 The Climate at Cambridge

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.

In this the Paleocene giant animals roamed the earth. Kate Lyons and Alessandro Mereghetti are scholars studying the extermination of those creatures. Some people believe that a way to protect our climate may be to repopulate our arctic with wooly mammoths and other animals. We discuss this.

On this monthly town hall meeting we discussed human similarities to animals and the nature of mind and the management of nuclear waste. To see the video, audio podcast, transcript, and comments: https://tosavetheworld.ca/episode-596-global-town-hall-mar-2024.

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.

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. Therefore, Dyer devotes the first half of the book to convincing the reader that, like it or not, we must start iimmediately getting ready. An edited transcript of this conversation will appear in the April 2024 issue of Peace Magazine.

A chat with whale and Arctic experts Edwina Tanner, Krys Chutko, and Joe Roman discuss the impact of the big sea mammals on our environment and the way human activities have decimated them. Surprisingly important is their digestive system, which affects the proliferation of phytoplankton.

News: Franz Oeste has found several other aerosols that can demolish methane in the atmosphere even faster. Clive Elsworth explains with slides to Peter Wadhams and Adele Buckley For the vieo, audio pocast, transcript and comments: https://tosavetheworld,ca/episode-591-new-aerosol-discoveries.

Discussing foxes, monkeys, bison, and cats are Bil Leikam and Alexey Prokhorenko. Then we talk about war with Richard Denton and Charles Tauber, and about nuclear waste with Sandy Greer.

Is economic growth lethal for the environment? Francesco Mellino and Richard Sandbrook discuss the dilemma and a recent journal that Mellino edited for C-40, the organization of mayors around the world who are collaborating for urban sustainability.

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?
