The Breathing Earth 

The Breathing Earth is real-time simulation that displays the CO2 emissions of every country in the world, as well as their birth and death rates. 

The designers ask users to remember the real time simulation is just that: a simulation. Although the CO2 emission, birth rate and death rate data used in Breathing Earth comes from reputable sources, data that measures things on such a massive scale can never be 100% accurate.

Note however that the CO2 emission levels on the simulation are more likely to be too low rather than too high.
