Monitoring surface temperatures does not give us an accurate enough representation of human-induced global warming. As long as we lack a clear understanding of the relationship between our cumulative greenhouse-gas emissions and the temperature of the earth, it will remain difficult to assess the potential for damage related to climate change caused by humans – or develop the right strategies to minimize it.
有一点是清楚的。监控表面温度无法让我们足够准确地观察人为造成的全球变暖。除非我们能更清楚地理解我们的累计温室气体排放量和地球温度之间的关系，否则评估与人为导致的气候变化有关的潜在危险就十分困难，制定使这一危险最小化的正确战略也十分困难。
