## Resource

As global temperatures continue to rise due to greenhouse gas emissions, can we dim the sunlight to cool the Earth? The idea may sound extreme, but solar radiation management, or solar geo-engineering, has already become a serious subject of scientific research. And it's not just scientists—billionaires like Elon Musk and Bill Gates have also shown interest. How viable is this concept in practice? What ethical, environmental, and global governance challenges could it bring? Zhao Ying speaks with John Moore, a research professor at the Arctic Center, University of Lapland in Finland. From 2015 to '22, he led the Chinese geoengineering research program while serving as Chief Scientist at the College of Global Change and Earth System Science, Beijing Normal University.
