That, in turn, produced estimated annual emissions of between 22 and 23 megatons of carbon dioxide, slotting the operations between the nations of Jordan and Sri Lanka in terms of greenhouse-gas pollution." It creates more CO2 than entire nations. And that number most definitely has not decreased in the past two years. We may very well be up to or past 0.1% of all global CO2 emissions due solely to crypto mining, a number that will only increase as the value of bitcoin, etc increases. What is the good that has been gained that offsets that?
