Anthropogenic Global Warming: The Greatest Fraud in History?
As a geologist what has always gotten to me was that the carbon dioxide levels we have now are some of the lowest they have ever been in the history of Rock 3 from the star Sol. You can go back to the carboniferous and find levels of carbon dioxide, methane and water vapor all much, much higher than they are today by at least a factor of 20. Yet… the planet was not only *not* in a runaway greenhouse affair, but reached a steady temperature that is constantly seen during eras of global single connected oceanic flows. You want to go back to the lovely warmth of the cretaceous, then slow down the continents, get rid of the isthmus between the two Americas and let the continents settle down and get those lovely oceanic waters on them to shallow depths so they can retain more heat.
Atmosphere sucks as a heat retention mechanism unless you can get it very dense, like Venus. Plus Venus is just a tad closer to the sun than we are…
AGW did not explain any of the artifacts of the historical record seen in geology. As a hypothesis it failed at the get-go. Mind you, when geologists talk about nasty extinction level events, you usually get something that is: 1) nasty, 2) unstoppable, 3) natural in cause. Megavolcanic events, boloids impacting the planet, gamma ray bursts… global warming? Of *course* it is warming we are coming out of an ice age and the little ice age. But then that is pointing to historical evidence in the scientific record. Can’t have that, now, can we?
