They are a better measure of the threats posed by climate change than heat sequestered underwater. But some of the threats that scientists (and economists) deduce from the surface temperature also reflect natural climate change, and thus cannot be mitigated through the reduction of CO2 emissions.
平心而论，地表温度仍是很重要。它们更适合作为气候变化所带来的危机的衡量指标，而非隐匿于水下的热量的衡量指标。但是，一些科学家（还有经济学家）根据地表温度推断的也反映了自然气候变化，因此不能通过减少二氧化碳排放遏制。
