The physical problem underlying climate change is very simple: dumping carbon dioxide and other greenhouses gases into the air raises their concentrations in the atmosphere and causes gradual warming. In the several decades since climate change has been an important international political issue.Reframing our understanding of carbon dioxide emissions can help clear the path for practical approaches to reducing carbon in the atmosphere, carboncan be tied up in mineral carbonates or biomass,bound up in materials that are used in the built infrastructure.Waste are often recycled, and the biggest opportunity for carbon recycling lies in the production of synthetic fuels from carbon dioxide, water, and renewable energy. Ramping up and down the production of such fuels could be used to balance the intermittencies created by the large-scale move to renewable energy for electricity grids
