ABSTRACT
Aggressive efficiency improvements and a shift away from fossil fuels cannot offset climate change threats. This realization creates an imperative for 'carbon-negative' mitigation measures; that is, measures that can reduce atmospheric carbon faster than emissions will load the atmosphere. Among such measures, air extraction technology, coupled with secure sequestration, offers advantages of centralization and control without direct intervention in the biosphere or major collateral environmental impact. Significant new scientific developments in air extraction show promise of greatly reduced costs, such that decreasing the concentration of carbon in the atmosphere to substantially lower risk levels may be economically practicable. These developments create a strong case for expanded R&D efforts aimed at advancing air extraction technology.
