Description: 環境科學家大衛基斯，針對氣候變遷提出一個令人震驚、卻又低價有效的方案：如果說我們可以在大氣層注入大量灰塵雲，使太陽光線與熱能折射的話呢?

大衛基斯對於氣候變遷的驚人構想

Injecting particles into the upper atmosphere could cool the planet quickly and at a fraction of global GDP, just as volcanic eruptions have temporarily done in the past. Although this approach could offset rising CO2 levels almost instantly, it introduces side effects like potential ozone depletion and moral hazards that could undermine emissions reduction efforts. As the pace of climate change accelerates and traditional solutions stall, society must openly debate the risks and ethics of radical interventions now possible through science.
