Then, in 1897, Svante Arrhenius, who earned a Nobel Prize for chemistry six years later, calculated how much global warming a doubling of CO2 in the atmosphere would cause. His answer was 4-6 degrees Celsius (a little more than the 2-4 degrees that modern studies consistently find).
接着在1897年，斯凡特·阿列纽斯计算出大气中二氧化碳含量翻倍能在多大程度上导致变暖结果。六年以后，阿列纽斯赢得了诺贝尔化学奖。他所得出的结果是4－6摄氏度（他的结果比现代研究一致发现的2－4摄氏度略高）。
