# Bitcoin emissions alone could push global warming above 2°C **

###### tags: `Green`,`HB`,`2018`,`CO2`,`environment`,`**`

### Résumé:
The projected Bitcoin usage,if it follows the rate of adoption of other broadly adopted technologies, could alone produce enough CO2 emissions to push warming above 2 °C within less than three decades.
Method:
studied the carbon emissions of Bitcoin if it follows the adoption trends of other broadly used technologies. For this, they used the incorporation rate of 40 different technologies for which data are readily available
For each year, they calculated the average and lower and upper quantiles of per cent population using all technologies and applied a logistic model to such trends
The projected trends of technology usage adoption were used to estimate likely Bitcoin usage assuming a global total of ~314.2 billion cashless transactions. They used only cashless transactions that are likely to occur in places where infrastructure is already in place for the usage of Bitcoin as a reference

### Opinion:
papier qui ne peut pas être considéré comme un veritable article scientifique mais qui s’en rapproche bcp, methodologie intéréssante et originale de comparaison avec les tendances des autres technos, mais une comparaison qui à mon sens peut vite paraître limitée. Aussi, c’est une étude qui ne prend en compte que l’état actuel du bitcoin pour nous montrer son impact environnemental
