Imagine a cube 27 feet tall, wide, and long. But just in case that’s a little hard to picture, imagine a cube almost as tall, wide, and long as a telephone pole. That’s how much space it would take to hold a metric ton of CO2. (We’re going to talk in metric tons here, because that’s how scientists measure CO2. A metric ton is 2,204.6 lbs, and is a little bigger than the American ton’s 2,000 lbs and a little smaller than the British ton’s 2,240 lbs —but the three are fairly comparable.)
And remember, this is literally a ton. While it may not seem like a gas can weigh that much, this 27’ x 27’ x 27’ cube has the same weight as a great white shark or, well, a ton of bricks (400 bricks!)The average American produces enough CO2 each year to fill 15 of these enormous cubes. This many cubes can fill over three Olympic-sized swimming pools. The Earth is able to reabsorb a lot of that CO2 through trees, oceans, and other natural processes. But much of it will stay in the atmosphere, potentially for hundreds of years.
That’s a lot of cubes. So how are we making all of this CO2?
