The clock is ticking: tic, tok, tic, tok …
The carbon clock of MCC (Mercator Research Institute on Global Commons and Climate Change) shows just how little time is left ’til the average global temperature increases by 1.5 or 2°C (2.7 – 3.4°F) – these are limits for warming which 195 countires signed (Paris Agreement, 2015). However even at +2°C climate changes will be considerable.

Different scenarios are discussed: at the lower left of the carbon clock you may select an estimation (lower, medium or upper) of how much time is left to limit CO2 concentrations so temperature increases only 2°C (or 3.6°F). Or click upper right to show the estimation of time remaining to keep temperatures to, or below, 1.5°C (2.7°F), the preferred scenario and limit.
To prevent temperatures rising more than 2°C, we have perhaps ~17 years left, depending on the scenario, to change how we all consume, recycle, develop and use technologies to help achieve that goal.
To keep to a 1.5°C increase, with a lower limit scenario, it’s too late: we reached the CO2 limit in January of 2016. For an upper limit scenario, by about April 2021 we will have increased temperature by 1.5°C. But there are many things now and in the future we can do to limit however the temperature increases.
