Rapid climate changes more deadly than asteroid impacts in Earth’s past – study shows. Posted on 27 May 2014 by howardleeThe link between rapid climate changes and mass extinctions has been strengthened in a recent paper by Jourdan et al in “Geology.” The authors demonstrate that the extraordinarily huge volcanic eruptions of the Kalkarindji Large Igneous Province (LIP) in Australia were synchronous with a major extinction event in the middle of the Cambrian Period, and they also show that most of the severe extinctions in the Phanerozoic (the time since the beginning of the Cambrian Period) have coincided with rapid climate changes brought about by greenhouse gas and sulfur emissions by LIPs like Kalkarindji, the Siberian Traps, and others. skepticalscience.com

RE: drought, crop failure, extreme weather Oh my, we've never experienced those before. Next thing you know, there'll be snow next winter.

Hi Land Shark; Re: "I wouldn't call mass extinction prosperity... the unfortunate side effects of climate change of drought, crop failure, extreme weather, collapse of fisheries will not be conducive to prosperity."; My theory is that lefties live in fear. "Mass extinction?" Okay, so name 100 species that were made extinct by man-made global warming. Heck name 6. Regarding drought, the amount hasn't changed. The biggest recent US drought was the 1930s, for example. Regarding crop failure, the human species is bigger than it's ever been but food growth has been so high that we're now turning most of our corn crop into fuel. Regarding extreme weather, weather has always been extreme. Regarding collapse of fisheries, some of this is due to overfishing. And the weather effects fisheries. In fact, "El Nino" was named not by the climate scientists but instead by the fishermen who noticed the effect that the weather had on fishing off of Peru. From wikipedia: El Niño affected pre-Columbian Incas [85] and may have led to the demise of the Moche and other pre-Columbian Peruvian cultures. [86] A recent study suggests a strong El-Niño effect between 1789 and 1793 caused poor crop yields in Europe, which in turn helped touch off the French Revolution. [87] The extreme weather produced by El Niño in 1876–77 gave rise to the most deadly famines of the 19th century. [88] The 1876 famine alone in northern China killed up to 13 million people. [89] An early recorded mention of the term "El Niño" to refer to climate occurred in 1892, when Captain Camilo Carrillo told the geographical society congress in Lima that Peruvian sailors named the warm north-flowing current "El Niño" because it was most noticeable around Christmas. The phenomenon had long been of interest because of its effects on the guano industry and other enterprises that depend on biological productivity of the sea. en.wikipedia.org -- Carl
