Can geoengineering be green?

摘要

In their provocative article, "Pursuing Geoengineering for Atmospheric Restoration," Robert B. Jackson and James Salzman put forth a new objective for the management of Earth. Atmospheric restoration would return the atmosphere "ultimately to its prein-dustrial condition." The authors arernpersuaded that the only responses to climate change are compensation and restoration, and they deeply dislike compensating for a changed atmosphere with other forms of planetary manipulation, notably injecting aerosols into the upper atmosphere.
