It’s been a staple of Globalwarmism that rising temperatures risk mass species extinction, but what appears to be going extinct at a rapid rate are warmist cliches. One of them is that the mass extinction of the Permian-Triassic era 250 million years ago was caused by global warming. Except, as reported by Emily Litella yesterday in Science Daily, it was the sudden ice age before the warming period that is responsible for the extinction:
Earth has known several mass extinctions over the course of its history. One of the most important happened at the Permian-Triassic boundary 250 million years ago. Over 95% of marine species disappeared and, up until now, scientists have linked this extinction to a significant rise in Earth temperatures. But researchers from the University of Geneva (UNIGE), Switzerland, working alongside the University of Zurich, discovered that this extinction took place during a short ice age which preceded the global climate warming. It’s the first time that the various stages of a mass extinction have been accurately understood and that scientists have been able to assess the major role played by volcanic explosions in these climate processes. This research, which can be read in Scientific Reports, completely calls into question the scientific theories regarding these phenomena, founded on the increase of CO2 in the atmosphere, and paves the way for a new vision of Earth’s climate history. (Emphasis added.)
Someone at Science Daily is going to get in trouble for the underlined sentence. Because you’re not allowed to say that.
