How strong will our commitment be to reversing the detrimental impacts of climate change? Will we abandon those efforts when they get expensive, or when we simply tire of the endeavors if they require prolonged and arduous work? A writer asks the question of Fulton Schools Professor Klaus Lackner, who directs ASU Center for Negative Carbon Emissions. Lackner and his research team are developing some of the more promising technologies to reduce the amount of harmful carbon dioxide in the atmosphere — a major cause of global warming. Lackner and others are a bit skeptical that our communal resolve will overcome the obstacles to long-term actions to pull back on the causes of climate change, but they see increasing agreement about the need to take action.
