Quiz: Capturing Carbon

Carbon capture is beginning to be seen as one of the main methods in limiting global warming. The Intergovernmental Panel on Climate Change has identified four means of limiting global warming, and they all call for removing carbon dioxide from the atmosphere. Carbon dioxide removal technologies (CDR) must remove 100 to 1,000 gigatonnes of the gas during this century, claims the IPCC. As work to remove carbon from the atmosphere accelerates, take this quiz to see what you know about carbon capture.
