The S... Has Hit the Fan With Global Warming

      It's been all over the news, except of course on the State run media (ABC, CBS, NBC, CNN, & MSNBC). All those emails that were hacked from the Climate Research Unit at Anglia University in England, the leading worldwide facility in climate research. The emails show that the data has been fudged, manipulated, and thrown away if it didn't present the "facts" they wanted it to show. All the talk is that humans are causing the global temperature to rise, through carbon dioxide emissions from the burning of fossil fuels, such as coal, and oil. How egotistical of the human race to think we can influence the global climate.
      This is just leading up to what I wanted to talk about. We are in an interglacial period right now, since the last continental glaciers finished receding about 10,000 years ago. Over the last 2 1/2 million years, the earth has had 5 glacial periods during which up to 30% of the continents were covered with glaciers up to a mile thick. Where did all that ice come from? When I was at the University of Connecticut, majoring in Geology back in the early 60's, we discussed a theory of the ice ages that still makes a whole lot of sense, and shows that what is going on today is natural and not caused by humans.
       About 2/1/2 million years ago, the continents arrived (continental drift) at their present locations. This set the stage for the start of the first ice age. At that time the Arctic ocean was open water. This allowed tremendous evaporation from the ocean that fell as snow across the continents. This eventually caused glaciers to start forming on the continents. All that snow and ice on the land caused a lot of sunlight to be reflected back into space causing the global temperature to drop causing global cooling and further glaciation. Eventually, the planet cooled to the point where the Arctic ocean froze. This cut off the evaporation that lead to the creation of the continental ice glaciers. With the influx of new snow cut off, the glaciers slowly started receding. As they receded, more land was exposed and not as much sunlight was reflected back into space, so the planet started warming again. Eventually, the glaciers disappeared as the planet warmed to the point that the Arctic ocean melted and became ice free again. The cycle started all over again, as it has five times, and will continue to do so until the continents realign themselves again. If the earth is warming, and the Arctic ocean is melting as the doomsayers would have you believe, then when it becomes ice-free again, I hope you have a big snow shovel, because we'll be headed into another ice age.
