Hot off the press - revolutionary climate finding - The worst extinction event in earth's history (according to wikipedia) was caused by global cooling - not by global warming (as previously thought). So much for "the science is settled"
Quote (from WUWT):
... Scientists from the UNIGE explain the global temperature drop by a stratospheric injection of large amounts of sulphur dioxide reducing the intensity of solar radiation reaching the surface of the earth. “We therefore have proof that the species disappeared during an ice age caused by the activity of the first volcanism in the Siberian Traps,” added Urs Schaltegger. This ice age was followed by the formation of limestone deposits through bacteria, marking the return of life on Earth at more moderate temperatures. The period of intense climate warming, related to the emplacement of large amounts of basalt of the Siberian Traps and which we previously thought was responsible for the extinction of marine species, in fact happened 500,000 years after the Permian-Triassic boundary ...--WUWT
Alarmists think CO2 caused the P-T event, 252 million years ago, by causing run-away global warming. They got everything precisely back to front. They are exactly wrong. This P-T event is one of the reasons they get so uptight and rude when you don't believe their propaganda. Many of them think they are saving the world from an analogous P-T extinction by stopping "carbon pollution". Idiots!!!
