What would a city’s CO2 emissions look like?

One ton of CO2 would fill a sphere 33 feet across. The office of the mayor of New York City decided to take this information and, given the city’s overall CO2 emissions, visualize exactly what New York’s CO2 emissions would look like if all of the gas was condensed around the center of Manhattan. The screenshots above are taken from Michael Bloomberg’s video, and the visuals are dramatic - the emissions after only an hour tower over nearby buildings, and after just one day, the Empire State Building would be swallowed by CO2. The scariest part of the whole project? New York is only the 5th worst city in terms of per capita emissions.
