Those of you who are wringing your hands over climate change and increasing CO2 concentration in the atmosphere, please read: Inconvenient Facts: The science that Al Gore doesn’t want you to know by Gregory Wrightstone. The facts and geological history which Mr. Wrightstone presents ends the man made climate change debate. There is climate change alright, and it’s been going on for 4 billion years. The earth was once an ice ball. There are glacial periods and interglacial periods–be glad we have a warm earth to live in now. There were warmer periods than we have now–the medieval warm period lasted for 400 years, between about 950 to 1350. The Vikings settled the coast of Greenland and engaged in agriculture and had livestock. When Michael Mann (Penn State) and Phil Jones (East Anglia University) were exchanging emails (climategate) about their hockey stick theory, they couldn’t address the medieval warm period because there was no industrial activity to explain it. Of course everyone (IPCC) was on board with the hockey stick until it was discredited. There have been periods in millenia past that had much higher CO2 concentrations in the atmosphere. Also, there are no data sets that demonstrate a correlation between increasing CO2 and increasing temperature. There is some data to suggest that an increase in CO2 follows an increase in temperature. Carbon dioxide is a trace gas in the atmosphere–400 parts per million. That’s 0.04%. So nix on the carbon taxes; and drill baby drill. Keep flying those jet A powered planes and helicopters, and leave the batteries to power our phones and computers. And when the batteries catch on fire, hope you’re not in a craft that’s powered by the damn things.
