If all $11 billion were spent on solar and wind in the same proportion as current global spending, global CO₂ emissions would fall by about 50 million tons each year. Run on a standard climate model, this would reduce temperatures so trivially – about 0.00002oC in the year 2100 – that it is the equivalent of postponing global warming by the end of the century by a bit more than seven hours.
如果这110亿美元如同当前全球开支比例一样全部用于太阳能电和风电，全球二氧化碳排放量每年可以减少大约5,000万吨。用标准气候模型计算，这对气温的降低效应可以忽略不计——到2100年可降低0.00002℃——相当于让截至本世纪末的全球变暖趋势停止七个多小时。
