Scientists use liquid metals to turn carbon dioxide gas back into coal

If we're going to curb the worst case scenario of climate change, it's not enough to just cut back on future carbon dioxide emissions – we need to remove some of what's already in the air. Capturing carbon from the air and sequestering it is emerging as a viable strategy, and now scientists have developed a new method to turn CO2 gas back into solid coal, that can then be buried, or even used for electronic components.
