How many gigatons…?

Saw an interesting Pinterest-style graphic the other day, relating to climate change and the amount of carbon dioxide (measured in gigatons) that has been and could be released, with the impacts of the different levels.

The scary part of the image is the part about there only being 13 years left before we break the budget of carbon released – the level of 500 gigatons. This will lead to 2 degrees C of warming, beyond which point there is a 50% chance of run-away climate change. Hardly a safe level, but the stages beyond are even more scary.

If carbon-capture and storage (CCS) technology isn’t introduced very soon (to capture the carbon from the inevitable use of fossil fuels for energy production), we’ll be beyond the 2 degree range in less than 2 decades.
