우리가 온실가스를 대기로 배출함으로써 지구의 온난화를 무자비하게 가중시키고 있는 동안, 산업용 배기가스 배출은 태양 빛을 우주로 다시 반사해보내는 입자를 생산하고 있고, 그것은 우리가 이제 겨우 이해하기 시작한 지구 온난화를 억제합니다. 기후변화 운동가인 켈리 왠저는 우리에게 묻습니다. 우리가 이러한 효과를 활용하여 온난화를 감소시킬 수 있는 방법을 고안할 수 있을까요? "구름 표백"의 가능성과 위험성에 대해서 알아보고, 그것이 우리 기후를 다시 건강하게 복구시키는데 어떻게 도움이 될지도 알아봅시다.

About the speaker
Kelly Wanser helps study and invent global-scale technological interventions that could save humanity from the worst effects of climate change.
The Guardian, 2019 | Article
"If all else fails"
Man-made global cooling is scary, but may become necessary.
National Research Council, et al. | National Academies Press, 2015 | Book
Climate Intervention: Reflecting Sunlight to Cool Earth, National Academy of Sciences
A scientific assessment of possible methods of directly cooling climate — from painting roofs to plastic on ice to mirrors in space. It reviews the science with evidence supporting reflecting sunlight from the atmosphere as the most promising approach.
Oliver Morton | Princeton University Press, 2017 | Book
The Planet Remade: How Geoengineering Could Change the World
As with all books by the esteemed science author and Economist editor, a marvelously well-written, captivating tour of the issues, deeply grounded in science and history. He makes a compelling case for technological interventions in climate.
Stewart Brand | Penguin Books, 2010 | Book
Whole Earth Discipline: Why Dense Cities, Nuclear Power, Transgenic Crops, Restored Wildlands, and Geoengineering Are Necessary
A healthy planet that supports humans requires sophisticated technologies, used wisely, to provide the scale of capabilities they need while preserving the natural systems they rely on. Thought-provoking ideas outside the environmental canon, from the prophetic environmentalist and futurist who helped change the way we see the planet and our future on it.
David Grinspoon | Grand Central Publishing, 2016 | Book
Earth in Human Hands: Shaping Our Planet's Future
Seen from the perspective of an astrobiologist on another planet, the intelligent life on Earth has been altering the planet's geology. But they are accidentally trashing the place, and their intelligence may need to be applied to ensure it can support humans into the future. A profound and entertainingly written gem.
David Biello | Scribner, 2017 | Book
The Unnatural World: The Race to Remake Civilization in Earth's Newest Age
Powerful individuals and technological innovation may not be able to solve the climate problem on their own, but they play a pivotal and hopeful role, wonderfully illustrated here. Or, as Esquire says, "A futurist ray of hope amid the usual denial and despair."

"Solar Geoengineering to Reduce Warming in the Earth System: The imperative for research"
Read my written testimony for the House Science, Space and Technology Committee, Subcommittee on Environment and Subcommittee on Energy Hearing — Geoengineering: Innovation, Research, and Technology, from November 8, 2017.
Kelly Wanser | Medium, 2018 | Article
"As climate risks increase, will geoengineering become a safer alternative?"
Public debate often places climate risks in the context of "this century" or "by 2100." But scientists are increasingly highlighting the risks of devastating and irreversible impacts in just 20 or 30 years. This is within our lifetimes, and certainly within our children's.
