One of the more promising systems to stem the negative impacts of climate change by capturing carbon dioxide from the atmosphere is being developed by the research team of physicist Klaus Lackner, Fulton Schools professor of civil, environmental and sustainable engineering and director of ASU’s Center for Negative Carbon Emissions. Lacker tells Ensia, a magazine focusing on solutions to environmental challenges, that such a system theoretically could remove CO2 from the air many times more efficiently than plants.
