World Carbon Dioxide Emissions Since the year 1750

World CO2 since 1750 (cubic feet)

Since 1750, humans have emitted over 5 trillion pounds of carbon dioxide into the atmosphere. Roughly half of this has ended up in the oceans where it is beginning to damage the coral reefs. The other half is still in the atmosphere and causing global warming.

Now, imagine if that carbon dioxide was separated back into carbon and oxygen- imagine if the carbon was turned back into a solid form and deposited back onto the surface of the earth- a black hail covering the surface of the earth with a ubiquitous layer of carbon dust.
