Different types of solar geoengineering are seeing a push for more research.
ABC News Chief Meteorologist and Chief Climate Correspondent Ginger Zee joins Make Sunsets founders Luke Iseman and Andrew Song for a balloon launch in San Jose, California.ABC News is taking a look at solutions for issues related to climate change and the environment with the series, "The Power of Us: People, The Climate, and Our Future."
While some experts have been researching techniques that could cool the planet for decades, there have been very few experiments in the field and critics argue we don't know enough about potential impacts on weather and climate events, water cycles, or food production. Sarah Doherty, program director of the Marine Cloud Brightening Project and associate professor at the University of Washington, says that emissions from ships traversing the globe have already been triggering a similar process.
The study consists of blowing tiny particles of salt water into the air and using a variety of research instruments to study the evolution of a sea-salt aerosol plume as it rises higher into the atmosphere. "If we understand the science of what particles do to clouds and how that affects the climate system, it's a win-win, whatever that science turns out to be, because we need to know it to know about pollution and what happens in the near term. And it's what you need to know to know whether marine cloud brightening might be something that you would consider for, you know, lessening climate impacts," Wanser told ABC News.
"So solar geoengineering can, in combination with emissions cuts and eventually with carbon removal, reduce the overall damage of climate change. That's its promise."
