Well, so what's new with that, I hear you say? And indeed, not much is the answer. But its a saturday night so some knock-about fun is in order. So, Watts, along with most of the septic blogosphere, was all over An ikaite record of late Holocene climate at the Antarctic Peninsula by Zunli Lua et al.. Not because they care about the science, but because the abstract says This ikaite record qualitatively supports that both the Medieval Warm Period and Little Ice Age extended to the Antarctic Peninsula. In septic-world, it is very important that the MWP and LIA be global, so that instantly…
This is just one of dozens of responses to common climate change denial arguments, which can all be found at How to Talk to a Climate Sceptic. Objection: Today's warming is just a recovery from the Little Ice Age. Answer: The problem with this argument is that it relies on an implicit assumption that there is some particular climate that the earth needs to be at and that given a period of globally lower temperatures, an eventual rise is inevitable. What is the scientific basis for such an assumption? There is no evidence that such a situation exists. The climate is influenced by many…
This is just one of dozens of responses to common climate change denial arguments, which can all be found at How to Talk to a Climate Sceptic. Objection: The Hockey Stick graph, the foundation of global warming theory, has been refuted and shown to be scientifically invalid, perhaps even a fraud. Answer: The first order of business here is to correct the mischaracterization of this single paleoclimate study as the "foundation" of Global Warming theory. It is anything but! What is going on today is unique and is understood by study of today's data and the best scientific theories the…
