However, the case for intervention to keep CO2 levels within bounds (say, aiming to stabilize them at about 550 ppm) is sufficiently strong to be insensitive to this dispute. Consider some numbers from the Stern Review concerning the future benefits of preventing greenhouse gas concentrations from exceeding 550 ppm, as well as the costs of accomplishing this.
不过，进行干涉以便把二氧化碳水平控制在一定范围内（比如，把它稳定在万分之五点五的水平）有足够强的论据支持，根本不需要牵涉到这种争论。看一下《斯特恩报告》中对于防止温室气体浓度超过万分之五点五所带来的未来利益以及完成这一目标所需要花费的代价的那些数据就很清楚了。
