Earth on the Brink of Ice Age

The central piece of evidence that is cited in support of the AGW theory is the famous ‘hockey stick’ graph which was presented by Al Gore in his 2006 film “An Inconvenient Truth.” The ‘hockey stick’ graph shows an acute upward spike in global temperatures which began during the 1970s and continued through the winter of 2006/07. However, this warming trend was interrupted when the winter of 2007/8 delivered the deepest snow cover to the Northern Hemisphere since 1966 and the coldest temperatures since 2001. It now appears that the current Northern Hemisphere winter of 2008/09 will probably equal or surpass the winter of 2007/08 for both snow depth and cold temperatures.

The main flaw in the AGW theory is that its proponents focus on evidence from only the past one thousand years at most, while ignoring the evidence from the past million years -- evidence which is essential for a true understanding of climatology. The data from paleoclimatology provides us with an alternative and more credible explanation for the recent global temperature spike, based on the natural cycle of Ice Age maximums and interglacials.About 325,000 years ago, at the peak of a warm interglacial, global temperature and CO2 levels were higher than they are today. Today we are again at the peak, and near to the end, of a warm interglacial, and the earth is now due to enter the next Ice Age. If we are lucky, we may have a few years to prepare for it. The Ice Age will return, as it always has, in its regular and natural cycle, with or without any influence from the effects of AGW. whole article

  1. I knew having these hot flashes would come in handy..think of how much money I'll save on utilities..

  2. YDG, if things get cold enough...
    "How do you heat the place?"
    "We hired 10 ladies having hot flashes to stand around for heat, it's expensive but not as much as electricity!"

    McRaven, Minnesota's probably pulling for global warming.

  3. stephen hawking's an ok guy but we need einstein to figure this out.

    i'd also like tesla's opinion.

  4. today we are bouncing to a high of -30 below and a low tonight of -50. Coldest night on record...yippie! Now I have to go run my hands under hot water so I can feel my fingers...

  5. Billy - Tesla could probably invent something to control the weather.

    McRaven - we got up to 60 today but we're plunging into the teens tonight with strong North winds.
    I know that's nothing compared to up there though. I wish I didn't have to read meters tomorrow! I think I'm big enough not to get blown away by the wind but if I do...tell them to look for me on the North side of the fences.
