We propose an innovative way (although it dates 1800 years back) to deal with climate agreements or, if preferred, amend current climate agreements (i.e. COP21): What do climate change and the Babylonian Talmud rule have in common?
Climate change can be seen as the result of an unsolved carbon budget bankruptcy. Limiting the global cumulative CO2 to 1,440 Gt, over the period 2000–2050, would yield a 50 % probability of exceeding the 2 â—¦C of the average temperature above pre-industrial levels (Meinshausen et al. 2009). However, it is estimated that the world’s cumulative emissions for the period in question will range from 1,758 to 2,736 Gt (IPCC 2000). Consequently, environmental global governance will find itself in a situation of carbon bankruptcy: countries will have claimed more cumulative emissions (1,758–2,736 Gt) by 2050 than those actually available
