Our Remaining carbon budget ...
'The MCC Carbon Clock shows how much CO2 can be released into the atmosphere to limit global warming to a maximum of 1.5°C and 2°C, respectively. With just one click, you can compare the estimates for both temperature targets and see how much time is left in each scenario.'
