最后,大灭绝的最终原因是全球变暖或全球变冷,通常是由其他事件之一引起的。据信全球的冷却和冰川消融导致了奥陶纪末期,二叠纪-三叠纪和泥盆纪晚期的灭绝。尽管温度下降杀死了一些物种,但随着水变成冰,海平面下降的影响更大。全球变暖是一个更为有效的杀手。但是,不需要太阳风暴或红色巨人的极端高温。持续加热与古新世-始新世的热最大值,三叠纪-侏罗纪的灭绝和二叠纪-三叠纪的灭绝有关。大多数情况下,问题似乎在于较高的温度释放水的方式,增加了温室效应,并导致了海洋中的缺氧事件。在地球上,随着时间的推移,这些事件一直保持平衡,但一些科学家认为,地球有可能沿着金星前进。在这种情况下,全球变暖将对整个星球进行消毒。

Finally, the ultimate cause of extinction is global warming or global cooling, usually caused by one of the other events. Global cooling and glacial ablation are believed to have led to the extinction of the late Ordovician, Permian-Triassic and late Devonian periods. Although the temperature drop kills some species, as the water turns into ice, the effect of sea level decline is greater. Global warming is a more effective killer. However, there is no need for extreme storms or extreme heat from the Red Giant. The continuous heating is related to the thermal maximum of the Paleocene-Eocene, the extinction of the Triassic-Jurassic and the extinction of the Permian-Triassic. In most cases, the problem seems to be the way in which water is released at higher temperatures, increasing the greenhouse effect and causing anoxic events in the ocean. On Earth, these events have been balanced over time, but some scientists believe that the Earth is likely to move along Venus. In this case, global warming will disinfect the entire planet.
