Climate engineering-which could slow the pace of global warming by injecting reflective particles into the upper atmosphere-has emerged in recent years as an extremely controversial technology. A leading scientist long concerned about climate change offers a proposal for an easy fix to what is perhaps the most challenging question of our time. After decades during which very little progress has been made in reducing carbon emissions we must put this technology on the table and consider it responsibly.
