What the heck is a "ton of carbon in the air?"

Help me visualize CO2 pollution. When we say we're spewing "tons of carbon" into the air, what does that look like? What does it mean when you measure a gas in tons? If I magically compressed a ton of carbon that's in the air to a density of, say, the graphite in pencil lead, what are the dimensions of that brick of carbon?
