双语阅读研究显示，挖比特币对气候的影响大于金矿开采

　　双语阅读
　　Bitcoin is less ＂digital gold＂ and more ＂digital beef＂, according to a study that suggests the cryptocurrency has a climate impact greater than that of gold mining and on the level of natural gas extraction or rearing cattle for meat. The research from the University of New Mexico, published in the journal Scientific Reports, assessed the climate cost of various commodities as a portion of their overall   market cap  .

　　比特币更像是＂数字牛肉＂，而非＂数字黄金＂，一项研究表明，比特币对气候的影响大于金矿开采、天然气开采或养牛的水平。新墨西哥大学发表在《科学报告》杂志上的一项研究，评估了各种商品的气候成本相较于其市场价值的比重。
　　Some, such as coal, cause almost as much damage as the entire value of the market they support, a 95% ratio, according to the analysis. Other commodities, such as pork production, generate huge climate impacts in absolute terms but only because the market is so massive.
　　翻译
　　根据分析结果，煤炭等一些能源对环境造成的损害几乎相当于他们创造的整个市值，比例高达95%。其他商品，如猪肉生产，从绝对值角度看也对气候产生了很大的影响，但只是因为市场规模很庞大。
　　Bitcoin, however, lies in between the two. According to the eco防no屏mist蔽s, the climate damage of producing the digital currency has averaged 35% of its market value over the past five years,   peaking at   82% in 2020. That is comparable to beef, which causes harm equal to 33% of its market, or natural gas, which hits 46%. And it is far in excess of gold, the commodity that the cryptocurrency’s backers most compare it to, which has a climate impact of just 4% of its market value, thanks to its enormous overall value   dwarfing   the large environmental impact of its extraction.

　　然而比特币介乎于两种情况之间。根据经济学家的观点，在过去五年里，生产数字货币对气候造成的损害平均占其市场价值的35%，而2020年达到了82%的最大水平。这相比之下，牛肉造成的损害相当于33%的市场价值，而天然气则占到了46%。
　　The digital currency’s disproportionate harm to the climate comes from its reliance on a computing process to verify transactions called ＂proof-of-work mining＂, which requires huge electricity expenditures to participate, rewarding those who carry it out with the chance to win some new bitcoin.
　　翻译
　　数字货币对气候造成的过大的危害来自于它对一种名为＂挖矿工作证明＂的依赖，这是一种为了验证交易的计算机处理过程，需要耗费巨大的电力才能参与交易，参与交易的人将有机会赢得一些新的比特币。
　　On more than one day of 20 in the period the researchers examined, the climate damage from these ＂bitcoin miners＂ exceeded the value of the coins produced, overwhelmingly due to that electricity consumption. Some have argued that renewables could cover this demand but the authors wrote that the climate damage for each dollar of value created was 10 times worse for bitcoin than for wind and solar generation – representing ＂a set of red flags for any consideration as a sustainable sector＂.
　　翻译
　　在研究人员开展调查的20多天期间里，不止一天出现了＂比特币矿工＂对气候造成的破坏超过比特币产生的价值的情况，造成这一问题的主要原因在于电力的耗用。一些人认为，可再生能源可以满足这一需求，但作者写道，比特币每创造一美元价值对气候的破坏，是风能和太阳能发电的10倍，这代表着＂给任何一种可持续发展行业都发出了一连串的危险信号。＂
