Kelly Wanser from SilverLining joins us to discuss techniques for climate intervention to mitigate the impacts of human induced climate change. Topics discussed in this episode include: - The risks of climate change in the short-term - Tipping points and tipping cascades - Climate intervention via marine cloud brightening and releasing particles in the stratosphere - The benefits and risks of climate intervention techniques - The international politics of climate change and weather modification You can find the page for this podcast here: https://futureoflife.org/2020/09/30/kelly-wanser-on-marine-cloud-brightening-for-mitigating-climate-change/ Video recording of this podcast here: https://youtu.be/CEUEFUkSMHU Timestamps: 0:00 Intro 2:30 What is SilverLining’s mission? 4:27 Why is climate change thought to be very risky in the next 10-30 years? 8:40 Tipping points and tipping cascades 13:25 Is climate change an existential risk? 17:39 Earth systems that help to stabilize the climate 21:23 Days where it will be unsafe to work outside 25:03 Marine cloud brightening, stratospheric sunlight reflection, and other climate interventions SilverLining is interested in 41:46 What experiments are happening to understand tropospheric and stratospheric climate interventions? 50:20 International politics of weather modification 53:52 How do efforts to reduce greenhouse gas emissions fit into the project of reflecting sunlight? 57:35 How would you respond to someone who views climate intervention by marine cloud brightening as too dangerous? 59:33 What are the main points of persons skeptical of climate intervention approaches 01:13:21 The international problem of coordinating on climate change 01:24:50 Is climate change a global catastrophic or existential risk, and how does it relate to other large risks? 01:33:20 Should effective altruists spend more time on the issue of climate change and climate intervention? 01:37:48 What can listeners do to help with this issue? 01:40:00 Climate change and mars colonization 01:44:55 Where to find and follow Kelly This podcast is possible because of the support of listeners like you.
