全球变暖的突然插曲标志着古新世时代的结束。来自两个相距甚远的地点的氧和碳同位素记录支持这样的观点，即生物来源甲烷水合物的脱气可能是改变地球气候的一个重要因素。这些数据显示了多次注入甲烷的证据，这些甲烷被碳循环处于停滞状态的间隔隔开。这两个地点之间的关联表明，即使是这些小规模的事件本质上也是全球性的。
An abrupt episode of global warming marked the end of the Paleocene epoch. Oxygen and carbon isotope records from two widely separated sites support the notion that degassing of biogenic methane hydrate may have been an important factor in altering Earth's climate. The data show evidence for multiple injections of methane, separated by intervals in which the carbon cycle was in stasis. Correlations between the two sites suggest that even these small-scale events were global in nature.
